[Problems to be Solved by the Invention] In recent years, it has been desired to increase the volume of a storage compartment such as a refrigerating compartment. At this time, the machine room has been relatively miniaturized in order to increase the volume without increasing the size of the body. As a result, it is not possible to install the large condenser in the machine room, and it is necessary to take measures such as providing a heat pipe separately on the back side of the refrigerator, thereby ensuring the necessary amount of heat radiation and the like. Therefore, a refrigerator capable of achieving a high volume of the storage compartment and ensuring the amount of heat radiation required for the refrigeration cycle is provided. [Means for solving the problem]

The refrigerator of the embodiment performs heat exchange in a refrigerating cycle using a multiflow type condenser including a flat tube formed in a flat shape and internally formed with a plurality of streams through which the refrigerant flows a road; and a header that becomes the inlet or outlet of the refrigerant flowing to the flat tube.

Hereinafter, an embodiment will be described with reference to Figs. 1 to 21(a) to 21(d). As shown in FIG. 1, the body 2 of the refrigerator 1 is formed in a substantially rectangular shape. The body 2 includes a back plate 3, a left side plate 4, a right side plate 5, a top plate 6 and a bottom plate 7 (refer to FIG. 2), and the front surface is open. The opening of the front surface of the main body 2 is opened and closed by the door 10a (refer to FIG. 2). The back plate 3, the left side plate 4, the right side plate 5, the top plate 6, and the bottom plate 7 are exemplified, for example, a vacuum heat insulating panel or a foamed polyurethane, or the vacuum insulated panel and the combined use The structure of the foamed polyurethane is a structure that thermally insulates the storage chamber 10 (see FIG. 2) from the outside of the refrigerator 1.

In the present specification, as shown in FIG. 1 , the direction along the gravity in the state in which the refrigerator 1 is installed is referred to as the up-and-down direction, and the state in which the refrigerator 1 is viewed from the front is viewed from the left side plate 4 toward the right side. The direction of the plate 5 is referred to as a left-right direction, and the direction from the door 10a toward the back plate 3 side will be referred to as a front-rear direction. A machine room 8 is provided at a lower portion of the body 2. Further, the back plate 3, the left side plate 4, the right side plate 5, and the bottom plate 7 are formed with an opening portion 9 that communicates with the inside of the machine room 8 at a position corresponding to the machine room 8. When the cooling fan 20 (see FIG. 2) is actuated, each of the openings 9 functions as an intake port that sucks air from the outside into the machine room 8, or an exhaust port that discharges air from the inside of the machine room 8 to the outside. . According to the position of the cooling fan 20 in the machine room 8, it is determined whether the opening 9 functions as an intake port or functions as an exhaust port. Further, the opening portion 9 may be a simple slit, may be processed into a louver shape, or may be provided with a dust filter or the like.

As shown in FIG. 2, a compressor 11, a condenser 12, a cooling fan 20, and the like are provided in the machine room 8. The compressor 11 and the condenser 12 constitute a refrigeration cycle 21 together with an evaporator (not shown). In the present embodiment, an axial fan is used as the cooling fan 20. In the machine room 8, other components than the compressor 11, the condenser 12, and the cooling fan 20, which are omitted from illustration, are also provided. Further, of course, the control unit is also provided in the main body 2, and the control unit controls the entire refrigerator 1 including the compressor 11, the condenser 12, the cooling fan 20, and the like.

In front of the machine room 8, for example, a storage compartment 10 such as a vegetable compartment is provided, and the storage compartment 10 is opened and closed by a pull-open type door 10a. Further, above the machine room 8, for example, a storage compartment 10 such as a freezing compartment is provided, and the storage compartment 10 is opened and closed by a pull-open type door 10a. Further, although not shown in the drawings, a storage compartment 10 such as a refrigerating compartment is provided above the inside of the main body 2, and the storage compartment 10 is opened and closed by, for example, a rotary door 10a. Since the compressor 11 and the condenser 12 generate heat, the mechanical chamber 8 and each of the storage compartments 10 are partitioned by the heat insulating partition wall 10b.

In the present embodiment, a so-called multi-flow type condenser is employed as the condenser 12 provided in the machine room 8. The details of the multi-flow type condenser 12 will be described later. However, as shown in FIG. 3 and the like, the headers 13 are connected by the flat tubes 14, and a plurality of streams are arranged in parallel in the flat tubes 14. road. Hereinafter, the configuration will be referred to as a parallel type for convenience. Further, there is also a multi-flow type condenser 12 having the following configuration. As shown in FIG. 4 and the like, the headers 13 are connected by a flat tube 14 of a crucible. Hereinafter, for convenience, the configuration is referred to as a 蜿蜒 type. Further, a fin 15 is provided between the flat tubes 14.

Next, the action of the above configuration will be described. For example, according to FIG. 2, it is conceivable that the size of the storage unit is not increased, that is, in order to increase the volume of the storage compartment 10, it is necessary to relatively reduce the size of the machine room 8. However, if the machine room 8 is downsized, the volume of the machine room 8 is reduced. Therefore, it is not possible to provide a large unit capable of ensuring a sufficient amount of heat radiation. Therefore, in order to secure the necessary amount of heat dissipation, the following measures have been taken, for example, the heat pipe is additionally provided on the back side. On the other hand, in the present embodiment, the multi-flow type condenser 12 is employed. Since the multi-flow type condenser 12 has a large surface area even if it is small, it is possible to ensure sufficient heat radiation amount first, and it can also be provided in the machine room 8 after miniaturization.

However, in the case where the condenser 12 is provided, there are a number of aspects that should be noted. For example, as described above, since other components are also provided in the machine room 8, the arrangement position of the condenser 12 may be restricted depending on the position of the other components or the position of the opening portion 9. Further, particularly in the case of the refrigerator 1, since the storage compartment 10 such as a refrigerating compartment or a freezing compartment is provided, it is necessary to suppress the influence of heat generation on the storage compartment 10. Further, in the actual manufacturing process, it is also necessary to consider the ease of connection with the piping 17 (see FIG. 5 and the like) which will be described later.

That is, in the case where the multi-flow type condenser 12 is installed in the refrigerator 1, not only the condenser 12 is required to be small, but also the installation portion or the installation direction of the condenser 12 needs to be creatively designed. In the following, a plurality of structures (the structural example A to the structural example D) of the condenser 12 will be described, and then an appropriate setting example (setting example A to setting example D) of the structural example A to the structural example D will be described. .

<Structure Example A: Structure in which the refrigerant flows in one direction in a parallel manner> With reference to Fig. 3 to Fig. 5, a structural example A, which is a structure in which the refrigerant flows in one direction in a parallel direction, will be described. Hereinafter, for convenience, the condenser 12 of the structural example A is referred to as a condenser 12A by the suffix "A". In addition, each structural example mentioned later is also the same. However, when each structural example is demonstrated generally, it is demonstrated, without the suffix.

As shown in FIG. 3, a plurality of flat tubes 14 are provided in parallel between the two cylindrical headers 13 of the condenser 12A. Each of the flat tubes 14 has a plurality of flow paths formed therein, and each of the flow paths communicates with each of the headers 13. Therefore, in the flat tubes 14, the refrigerant flows in parallel. According to this configuration, it is called a multi-flow type or a parallel flow type.

Further, the refrigerant flowing into one header 13 on the inlet side flows through the flat tube 14 to reach the other header 13 on the outlet side. At this time, the fins 15 are in contact with the flat tubes 14, and therefore, the heat of the flat tubes 14 is released, and the fins 15 are disposed between the flat tubes 14 by, for example, forming a thin metal plate into a wave shape. . Hereinafter, the portion where the flat tubes 14 and the fins 15 are disposed will be referred to as a main body portion 12a for convenience. The main body portion 12a as a whole can be regarded as a rectangular parallelepiped shape in which the outer edge is substantially thin.

Hereinafter, the width direction of the main body portion 12a, that is, the direction from one header 13 to the other header 13 in Fig. 3 is referred to as an X-axis. Further, the height direction of the main body portion 12a, that is, the extending direction of the cylindrical header 13 in Fig. 3 is referred to as a Y-axis. Further, the direction in which the main body portion 12a is thick, that is, the direction orthogonal to the X-axis and the Y-axis is referred to as a Z-axis. Further, in FIG. 3, the directions of the arrows indicating the X-axis, the Y-axis, and the Z-axis are set to the positive direction, and the "+" is added to the positive direction with respect to the main body portion 12a, and the negative direction is opposite to the positive direction. The direction is appended with "-".

A connecting pipe 16 is provided in each of the headers 13 respectively. The connecting pipe 16 is provided to be connected to the pipe 17 (see FIG. 5 ) and is firmly connected to the header 13 , and the side connected to the pipe 17 is formed into, for example, a tubular shape that can be bent or bent, and It is connected to the pipe 17 by, for example, brazing. Hereinafter, for convenience, the connection pipe 16 on the refrigerant inlet side is referred to as an inlet side connection pipe 16a, and for convenience, the connection pipe 16 on the refrigerant outlet side is referred to as an outlet side connection pipe 16b. In this case, the direction of the inlet-side connecting pipe 16a is substantially in the X-direction, and the direction of the outlet-side connecting pipe 16b is substantially in the X+ direction.

In the case of the condenser 12A as described above, as shown in the simplified diagram of FIG. 4, the refrigerant flowing in from the inlet-side connecting pipe 16a is from the header 13 provided with the inlet-side connecting pipe 16a as indicated by an arrow F, The other flat tubes 14 flow into the other headers 13 and flow out from the outlet side connecting tubes 16b. That is, in the case of the condenser 12A, the refrigerant flows in one direction. At this time, the refrigerant is gas-like when flowing into the inlet-side connecting pipe 16a, and is condensed by the condenser 12, thereby becoming liquid when flowing out from the outlet-side connecting pipe 16b.

Therefore, with respect to the condenser 12, the temperature of the header 13 on the inlet side is relatively increased, and the temperature of the header 13 on the outlet side is relatively lowered. Moreover, the temperature of the inlet side of the flat tube 14 is the highest, and the temperature is gradually lowered as it approaches the outlet side. That is, the main body portion 12a of the condenser 12 generates a temperature distribution including the header 13.

Further, when the restriction caused by the installation portion or the installation direction is not considered, the degree of freedom in the direction of the inlet-side connecting pipe 16a and the outlet-side connecting pipe 16b is considered to be high. Specifically, as shown by the solid line and the broken line in FIG. 5 , the inlet-side connecting pipe 16 a can be disposed in various directions such as the X-direction, the Y+ direction, the Z+ direction, and the Z-direction with respect to the main body portion 12 a. Similarly, the outlet-side connecting pipe 16b can be disposed in various directions such as the X+ direction, the Y+ direction, the Z+ direction, and the Z-direction with respect to the main body portion 12a.

That is, the condenser 12 includes a connection pipe (inlet side connection pipe 16a, outlet side connection pipe 16b) formed to be from the body portion 12a in which the flat tubes 14 are disposed The protruding length is connected to the external pipe 17. Further, the connecting pipe (the inlet side connecting pipe 16a and the outlet side connecting pipe 16b) may extend in parallel with respect to the flat pipe 14, or may extend perpendicularly with respect to the flat pipe 14. Further, the direction of the inlet-side connecting pipe 16a and the outlet-side connecting pipe 16b with respect to the flat pipe 14 may be different, and the direction in which the main body portion 12a protrudes may be different. This is also the same for the condenser 12 (see FIGS. 9 and 12) and the like which will be described later.

In addition, although the illustration has been omitted, the inlet-side connecting pipe 16a and the outlet-side connecting pipe 16b are not necessarily strictly orthogonal or parallel to the respective directions, and may be slightly inclined or may be inclined substantially with respect to each axis. . Further, although the outlet-side connecting pipe 16b can be provided in the region R shown in FIG. 5, in this case, since the inlet and the outlet are close to each other, the refrigerant may not uniformly flow into all the flat tubes 14, and therefore, In the case of the condenser 12A, it is preferable to provide the inlet-side connecting pipe 16a and the outlet-side connecting pipe 16b as diagonal as possible.

However, the piping 17 connected to each of the connecting pipes 16 is in the vicinity of the condenser 12, corresponding to the direction of the connecting pipe 16. Therefore, for example, when the inlet-side connecting pipe 16a is provided to extend in the X-direction and the outlet-side connecting pipe 16b is provided to extend in the X+ direction as shown in FIG. 5, the pipe 17 is connected from the X direction, and therefore, considering When the size of the pipe 17 is included, the actual installation space required for providing the condenser 12A to some extent is required in the X direction, that is, in the width direction of the main body portion 12a. Similarly, for example, when the inlet-side connecting pipe 16a is provided to extend in the Z+ direction, a certain degree of installation space is required in the Z direction, that is, in the thickness direction of the body portion 12a. That is, the installation space is restricted in accordance with the direction of each of the connecting pipes 16.

<Structure Example B: Structure in which the refrigerant flows in two directions in a parallel manner> With reference to Fig. 6 to Fig. 8 , a structural example B which is a parallel type and a structure in which the refrigerant flows in two directions will be described. As shown in Fig. 6, the basic structure of the condenser 12B is the same as that of the condenser 12A, and a plurality of flat tubes 14 are provided in parallel between the two cylindrical headers 13. Each of the flat tubes 14 has a plurality of flow paths formed therein, and each of the flow paths communicates with each of the headers 13. Therefore, in the flat tubes 14, the refrigerant flows in parallel. Further, a fin 15 is provided between the flat tubes 14.

However, in the case of the condenser 12B, one header 13 is provided with both the inlet side connection pipe 16a and the outlet side connection pipe 16b, and between the inlet side connection pipe 16a and the outlet side connection pipe 16b is provided. Sealing portion 13a. The seal portion 13a seals the inside of the cylindrical header 13. That is, the sealing portion 13a divides the inside of one header 13 into two ranges. Further, the sealing portion 13a makes the number of the flat tubes 14 on the inlet side relatively large, and the number of the flat tubes 14 on the outlet side is relatively small. The reason is that the refrigerant is gas-like on the inlet side, and therefore has a large volume, and is condensed on the outlet side to be in a liquid state, so that the volume is reduced. Thereby, efficiency can be improved.

In the case of the condenser 12B as described above, as shown in the simplified diagram of Fig. 7, the gaseous refrigerant flowing in from the inlet-side connecting pipe 16a is located on the inlet side of the relatively sealed portion 13a as indicated by an arrow F. The inside of each flat tube 14 on the side of the connecting pipe 16a flows to the other header 13, and passes through the other header 13, and is reversed in each of the flat tubes 14 located on the side of the outlet side connecting tube 16b of the sealing portion 13a. After flowing, it flows out from the outlet side connecting pipe 16b. That is, in the case of the condenser 12B, the refrigerant flows in two directions. Hereinafter, the condenser 12 of such a configuration is referred to as a foldback type for convenience.

In the case of the condenser 12B, the degree of freedom in the direction of the inlet-side connecting pipe 16a and the outlet-side connecting pipe 16b is also high, regardless of the restriction caused by the installation portion or the installation direction. Specifically, as shown by the solid line and the broken line in FIG. 8 , the inlet-side connecting pipe 16 a can be disposed in various directions such as the X-direction, the Y+ direction, the Z+ direction, and the Z-direction with respect to the main body portion 12 a. Similarly, the outlet-side connecting pipe 16b can be disposed in various directions such as the X-direction, the Y-direction, the Z+ direction, and the Z-direction with respect to the main body portion 12a.

In the case of the condenser 12B, the piping 17 connected to each of the connecting pipes 16 is also in the vicinity of the condenser 12, corresponding to the direction of the connecting pipe 16, and therefore, the installation space is restricted in accordance with the direction of each connecting pipe 16. Further, although the illustration has been omitted, the inlet-side connecting pipe 16a and the outlet-side connecting pipe 16b may be slightly inclined or may be greatly inclined with respect to each axis.

<Configuration Example C: Structure in which the headers are disposed on the same side. Referring to FIGS. 9 to 11 , the configuration in which the headers 13 are disposed on the same side, that is, the inlet and the outlet of the refrigerant are used. A structural example C which is disposed on the same side with respect to the main body portion 12a will be described.

As shown in Fig. 9, a flat tube 14 is provided between the two smaller cylindrical headers 13 of the condenser 12C. The flat tube 14 has a plurality of flow paths formed therein, and each flow path communicates with each of the headers 13. That is, the crucible type condenser 12C bends a flat tube 14 in the thickness direction to connect the inlet and the outlet. In this case, the refrigerant also flows in parallel in the flat tubes 14. Further, a fin 15 is provided between the folded flat tubes 14. Further, in the case of the condenser 12C, the header 13 on the inlet side and the header 13 on the outlet side are provided on the same side with respect to the main body portion 12a.

In the case of the condenser 12C as described above, as shown in the simplified diagram of Fig. 10, the gaseous refrigerant flowing in from the inlet-side connecting pipe 16a flows to the other set in the flat pipe 14 as indicated by an arrow F. The tube 13 flows out from the outlet side connecting pipe 16b. Further, in addition to the direction perpendicular to the flat tubes 14 as shown in FIG. 9, the direction of the headers 13 may be considered in the horizontal direction or the coaxial direction of the flat tubes 14, but in the case of the condenser 12C, The header 13 itself is small, so the main cause of the space problem is the direction of the connecting tube 16.

In the case of the condenser 12C, the degree of freedom in the direction of the inlet-side connecting pipe 16a and the outlet-side connecting pipe 16b is also high, regardless of the restriction caused by the installation portion or the installation direction. Specifically, as shown by the solid line and the broken line in FIG. 11, the inlet-side connecting pipe 16a can be set in various directions such as the Z+ direction, the X-direction, the Y+ direction, the Y-direction, and the Z-direction with respect to the main body portion 12a. . Similarly, the outlet-side connecting pipe 16b can be disposed in various directions such as the Z+ direction, the X-direction, the Y+ direction, the Y-direction, and the Z-direction with respect to the main body portion 12a.

In the case of the condenser 12C, the piping 17 connected to each of the connecting pipes 16 is also in the vicinity of the condenser 12, corresponding to the direction of the connecting pipe 16, and therefore, the installation space is restricted in accordance with the direction of each connecting pipe 16. Further, although the illustration has been omitted, the inlet-side connecting pipe 16a and the outlet-side connecting pipe 16b may be slightly inclined or may be greatly inclined with respect to each axis.

<Configuration Example C: Structure in which the header is provided on the diagonal side> Referring to Fig. 12, the configuration in which the header 13 is disposed on the diagonal side, that is, the inlet and the outlet of the refrigerant are opposed A structural example D arranged on the diagonal line on the main body portion 12a will be described. As shown in FIG. 12, the condenser 12D is substantially the same as the condenser 12C, but the two cylindrical headers 13 are provided at diagonal positions with respect to the main body portion 12a.

In the case of the condenser 12C, the degree of freedom in the direction of the inlet-side connecting pipe 16a and the outlet-side connecting pipe 16b is also high, regardless of the restriction caused by the installation portion or the installation direction. Specifically, the inlet-side connecting pipe 16a can be disposed in various directions such as the Z+ direction, the X-direction, the Y+ direction, the Y-direction, and the Z-direction with respect to the main body portion 12a. Similarly, the outlet-side connecting pipe 16b can be disposed in various directions such as the Z+ direction, the X+ direction, the Y+ direction, and the Z-direction with respect to the main body portion 12a.

In the case of the condenser 12D, the piping 17 connected to each of the connecting pipes 16 is also in the vicinity of the condenser 12, corresponding to the direction of the connecting pipe 16, and therefore, the installation space is restricted in accordance with the direction of each connecting pipe 16. Further, although the illustration has been omitted, the inlet-side connecting pipe 16a and the outlet-side connecting pipe 16b may be slightly inclined or may be greatly inclined with respect to each axis.

Further, the condenser 12 shown in the structural examples A to D is also provided in various directions. For example, in the case of the condenser 12A, it is conceivable to provide a state in the height direction of the body portion 12a along the gravity direction as shown in FIG. 13(a), that is, the header 13 is along the gravity direction and the flat tubes 14 and the arrangement The state of the face level. Further, the illustration of the connecting pipe 16 is omitted in FIGS. 13(a) to 13(d).

Further, it is conceivable that the state in the width direction of the main body portion 12a, that is, the state in which the header 13 and the installation surface are horizontal and the flat tubes 14 are along the gravity direction, is provided along the gravity direction as shown in Fig. 13 (b). Further, it is conceivable that the state in the thickness direction of the main body portion 12a is provided along the gravity direction as shown in FIG. 13(c); or as shown in FIG. 13(d), the thickness direction of the main body portion 12a is obliquely provided with respect to the gravity direction. State, etc. Further, although the illustration has been omitted, a state in which the header 13 is provided obliquely with respect to the direction of gravity may be considered (see FIG. 20).

<Setting Example A> Hereinafter, the setting example A will be described with reference to FIGS. 14 and 15( a ) to 15 ( d ). Fig. 14 shows a setting example A, and schematically shows a state in which the machine room 8 is viewed from above. In the installation example A, the condenser 12 is provided such that the main body portion 12a is substantially parallel to the storage chamber 10 in front of the machine room 8. In this case, the outside air is taken in from the opening 9 provided in the bottom plate 7, and after cooling the condenser 12, the compressor 11 is cooled, and is exhausted from the opening 9 provided in the left side plate 4.

First, as described above, since the storage compartment 10 is provided in front of and above the machine room 8, it is preferable that the heat released by the condenser 12 has little influence on the storage compartment 10. In this case, since the distance to the storage compartment 10 on the front side of the machine room 8 is the same, it is considered that the influence on the storage compartment 10 (see FIG. 2) on the upper side of the machine room 8 is considered.

Further, as described above, since the condenser 12 condenses the gaseous refrigerant into a liquid state, it is preferable that the outlet-side connecting pipe 16b is located below. Further, since the right side plate 5 is present on the right side of the condenser 12, it is difficult to secure the space on the right side of the condenser 12. Further, in order to reduce the size of the machine room 8, it is not preferable if the space above the condenser 12 is increased.

In the case where these points of attention are referred to, for example, for the condenser 12A, it is preferable to provide the header 13 in the direction of gravity so as to be in the Z+ direction (the front side perpendicular to the paper surface) as shown in Fig. 15 (a) In the extending manner, the inlet-side connecting pipe 16a is provided in the header 13 on the right side of the figure of the main body portion 12a, and is in the Z-direction indicated by a solid line or the X-direction indicated by a broken line (left side in the drawing) In the extended manner, the outlet side connecting pipe 16b is provided in the header 13 on the left side of the drawing. 15(a) to 15(d) schematically show the state observed from the arrow XV of Fig. 14 .

By providing the above-described state, it is possible to suppress the influence of heat generation on the storage compartment 10 on the upper side of the machine room 8 as compared with the case where the headers 13 are arranged up and down (see FIG. 13(b)). Further, since the inlet side having a higher temperature is disposed on the outer side, it is possible to further suppress the influence of heat generation on the storage compartment 10 and other components in the machine room 8.

Further, since the inlet-side connecting pipe 16a is disposed on the upper side and the outlet-side connecting pipe 16b is disposed on the lower side, the flow of the refrigerant which changes from a gaseous state to a liquid state is not hindered by gravity. Moreover, since there is a comparative space on the lower side of the illustration of the condenser 12 in FIG. 14, it is easy to secure an installation space and it is easy to connect the piping 17. That is, it is considered that in the case of the condenser 12A, the arrangement as shown in the above-described FIG. 15(a) is appropriate.

Further, for example, in the condenser 12B, it is preferable that the header 13 is provided along the gravity direction as shown in FIG. 15(b), and the inlet-side connecting pipe 16a is provided in the figure so as to extend in the Z+ direction. The header 13 on the right side is provided on the lower side with the outlet side connecting pipe 16b interposed therebetween so as to extend in the Z+ direction.

By setting in the state as described above, it is possible to obtain the same effect as the condenser 12A, for example, it is possible to suppress the influence of the heat emitted from the condenser 12 on the storage compartment 10, and it is not hindered by securing the installation space. Since the refrigerant flows, the piping 17 and the like can be easily connected. That is, it is considered that in the case of the condenser 12B, the installation direction and the structure as shown in the above-described FIG. 15(b) are appropriate.

Further, for example, in the condenser 12C, as shown in FIG. 15(c), each of the headers 13 may be provided on the side of the right side plate 5, and the inlet-side connecting pipe 16a may be disposed to extend in the Z+ direction. The header 13 on the upper right side of the main body portion 12a is provided in the header 13 on the lower right side of the main body portion 12a so as to extend in the Z+ direction.

By setting in the state as described above, it is possible to obtain the same effect as the condenser 12A, for example, it is possible to suppress the influence of the heat emitted from the condenser 12 on the storage compartment 10, and it is not hindered by securing the installation space. Since the refrigerant flows, the piping 17 and the like can be easily connected. That is, it is considered that in the case of the condenser 12C, the installation direction and the structure as shown in the above-described FIG. 15(c) are appropriate.

Further, for example, as shown in FIG. 15(d), the condenser 12D may be provided with the header 13 so as to extend in the Z+ direction so as to be on the diagonal side of the right side plate 5 side and the right side plate 5 side. The inlet-side connecting pipe 16a is provided in the header 13 on the upper right side of the body of the main body portion 12a, and the outlet-side connecting pipe 16b is provided in the lower portion of the lower portion of the main body portion 12a so as to extend in the Z+ direction. 13.

By setting in the state as described above, it is possible to obtain the same effect as the condenser 12A, for example, it is possible to suppress the influence of the heat emitted from the condenser 12 on the storage compartment 10, and it is not hindered by securing the installation space. Since the refrigerant flows, the piping 17 and the like can be easily connected. That is, it is considered that in the case of the condenser 12C, the installation direction and the structure as shown in the above-described FIG. 15(b) are appropriate.

By providing in the state as described above, it is possible to suppress the influence of heat generation on the storage compartment 10 on the upper side of the machine room 8. At this time, when the condenser 12A is viewed from the side, the state is substantially as shown in Fig. 19 (a), and the cooling fan 20 is disposed in a space (S) formed by the inlet-side connecting pipe 16a and the outlet-side connecting pipe 16b. Thereby, space can be saved. That is, it is considered that in the case of the condenser 12A, the arrangement as shown in the above-described FIG. 21(a) is appropriate.

Further, in this case, it is preferable that the cooling fan 20 is disposed in a space (S) formed by the inlet-side connecting pipe 16a and the outlet-side connecting pipe 16b.

By setting in the state as described above, it is possible to obtain the same effect as the condenser 12A, for example, it is possible to suppress the influence of the heat emitted from the condenser 12 on the storage compartment 10, and it is not hindered by securing the installation space. Since the refrigerant flows, the pipe 17 can be easily connected, and space and the like can be saved. That is, it is considered that in the case of the condenser 12B, the installation direction and structure as shown in the above-described FIG. 21(b) are appropriate.

Further, for example, the condenser 12C preferably has the inlet-side connecting pipe 16a disposed on the right side of the main body portion 12a as shown in FIG. 21(c) so as to extend in the Z+ direction. Further, the outlet-side connecting pipe 16b is provided in the header 13 on the left side of the main body portion 12a. By providing the above-described state, it is possible to obtain the same effect as the condenser 12A, for example, it is possible to suppress the influence of the heat generated by the condenser 12 on the storage compartment 10, and it is possible to save space without hindering the refrigerant. Flowing, etc. That is, it is considered that in the case of the condenser 12C, the installation direction and structure as shown in the above-described FIG. 21(c) are appropriate.

Further, for example, the condenser 12D preferably has the inlet-side connecting pipe 16a disposed on the right side of the main body portion 12a as shown in FIG. 21(d) so as to extend in the Z+ direction. 13. The outlet-side connecting pipe 16b is provided on the right-side header of the main body portion 12a so as to extend in the Z-direction indicated by the solid line or the X-direction (the left side in the drawing) indicated by the broken line. 13. By providing the above-described state, it is possible to obtain the same effect as the condenser 12A, for example, it is possible to suppress the influence of the heat generated by the condenser 12 on the storage compartment 10, and it is possible to save space without hindering the refrigerant. Flowing, etc. That is, it is considered that in the case of the condenser 12D, the installation direction and structure as shown in the above-described FIG. 21(d) are appropriate.

Further, in the installation example D, the state in which the condenser 12 is close to the right side plate 5 is assumed, but in the case where the condenser 12 is close to the left side plate 4, the inlet side is connected as long as the idea contrary to the above examples is used. The direction of the tube 16a and the outlet-side connecting tube 16b may be set. As described above, the refrigerator 1 of the present embodiment employs the condenser 12 having a different structure depending on the installation position in the machine room 8.

According to the embodiment described above, the effects described below can be obtained. The refrigerator 1 performs heat exchange of the refrigeration cycle 21 using a multi-flow type condenser 12 including a flat tube 14 which is formed in a flat shape and internally formed with a plurality of pieces through which the refrigerant flows. a flow path; and a header 13 which becomes an inlet or an outlet of the refrigerant flowing to the flat tubes 14. Thereby, since the multi-flow type condenser 12 is small and has high performance, it can be installed in the machine room 8 after miniaturization. Therefore, the necessary amount of heat radiation can be secured by the condenser 12 provided in the machine room 8.

Further, since the multi-flow type condenser 12 can be expected to have a heat dissipation effect of about 2 to 3 times that of the condenser of the same volume, the heat radiation pipe provided in the related art can be eliminated, the structure can be simplified, and the manufacturing cost can be reduced. Moreover, the reduction in heat leaks in the storage compartment can also contribute to energy saving.

The condenser 12 may be disposed such that the extending direction of the flat tubes 14 is horizontal to the installation surface of the refrigerator 1, or the extending direction of the flat tubes 14 may be arranged perpendicular to the installation surface, and the main body portion 12a and the installation surface may be provided. The horizontal arrangement may be such that the main body portion 12a is inclined with respect to the installation surface. That is, the installation direction of the condenser 12 can be set according to the shape of the machine room 8, or the other components in the machine room 8. Thereby, the degree of freedom of setting can be improved.

In the state where the condenser 12 is already installed, the refrigerant flows in from the upper side. Thereby, the refrigerant which is condensed and becomes liquid is moved downward by gravity, so that the refrigerant can be liquefied efficiently, that is, the performance of the refrigeration cycle 21 can be improved. The refrigerant inlet side of the condenser 12 is disposed away from the storage chamber 10. Thereby, it is possible to suppress the storage compartment 10 or the heat insulating partition wall 10b from being warmed by the heat generated by the condenser 12, and it is possible to reduce heat leakage.

The condenser 12 is disposed in the machine room 8 and is disposed in the body 2 of the refrigerator 1. The machine room 8 is provided with an opening 9 for cooling the compressor 11, and it is easy to introduce and discharge the outside air. Therefore, by providing the condenser 12 in the machine room 8, the condenser 12 can be efficiently cooled, and the air heated by the condenser 12 can be efficiently discharged.

The condenser 12 includes a connection pipe 16 which is an inlet or an outlet of the refrigerant, and is formed to extend in the X direction, the Y direction, or the Z direction from the body portion 12a in which the flat tubes 14 are disposed. Further, the cooling fan 20 that cools the condenser 12 is formed to be smaller than the outer shape of the main body portion 12a, and is thinner than the protruding length of the connecting pipe 16, and is disposed between the main body portion 12a and the front end of the connecting pipe 16. Within the space formed (S. space).

Thereby, the cooling fan 20 can be installed in the space necessary for providing the condenser 12, and space can be saved. Further, as described above, the multi-flow type condenser 12 is small in size and high in performance, and can efficiently exchange heat even if the amount of air is small. Therefore, it is housed in a space formed by the main body portion 12a and the connecting pipe 16 (S The cooling fan 20 in the inside can also be sufficiently cooled.

(Other Embodiments) The present invention is not limited to the embodiments described above, and may be arbitrarily modified or expanded without departing from the scope of the invention, and may be modified or expanded, for example, as follows.

In the above-described embodiment, an example in which one condenser 12 is cooled by the cooling fan 20 is shown. For example, the configuration may be as shown in FIGS. 22(a) to 22(c). Two or more condensers 12 are cooled by one cooling fan 20. In this case, for example, as shown in FIG. 22( a ), the condenser 12 may be disposed obliquely with respect to the air blowing surface of the cooling fan 20 , and as shown by an arrow Y, the wind sent by the cooling fan 20 may be blown to each condensation. 12 Further, as shown in FIG. 22(b), the condenser 12 may be placed on the air blowing surface so as to be superposed on each other, and the wind sent by the cooling fan 20 may be blown to each of the condensers 12. Further, as shown in FIG. 22(c), a plurality of condensers 12 may be arranged side by side on the air blowing surface.

By providing the plurality of condensers 12 in the above manner, the capacity of the refrigeration cycle 21 can be improved, and the plurality of condensers 12 can be cooled by one cooling fan 20, whereby space can be saved. In this case, a parallel or 蜿蜒 type condenser may be separately provided, or a parallel or 蜿蜒 type condenser may be provided in combination.

In the embodiment, the condenser 12 including one main body portion 12a is exemplified, but as shown in Figs. 23(a) and 23(b), for example, the condenser 12 including the plurality of main body portions 12a may be used. Thereby, the ability of the refrigeration cycle 21 can be improved without causing the condenser 12 to be excessively enlarged. Thereby, the surface area of the condenser 12 can be increased, or the condenser 12 can be made thinner, and the space occupied by the condenser 12 can be made small. Moreover, the heat dissipation efficiency can also be improved.

Further, although the two main body portions 12a are shown in Figs. 23(a) and 23(b), three or more main body portions 12a may be included. Further, instead of folding as shown in FIGS. 23(a) and 23(b), the main body portions 12a may be angled to each other. Further, the plurality of body portions 12a may be connected in series or may be connected in parallel.

In the embodiment, an example in which the condenser 12 is cooled by the cooling fan 20 is shown. For example, as shown in FIGS. 24(a) and 24(b), the defrosting water (W) may be used. The configuration is dropped from above the condenser 12. Further, the defrosting water is water generated when the frost adhered to a cooler (not shown) is dissolved. Thereby, the condenser 12 can be efficiently cooled by the defrosted water. At this time, if the direction of the condenser 12 is set such that the flat tubes 14 are along the gravitational direction, the defrosted water can be caused to flow down the flat tubes 14 by gravity, and the cooling water can be prevented from staying on the fins 15 and can be retained. Cooling is performed efficiently.

In this case, the defrosted water may be dropped from the front surface, that is, in the direction of the Z-axis described in the embodiment, to the main body portion 12a. In addition, the defrosting water (W) may be dropped at all times, and the defrosting water (W) may be periodically dropped. Thereby, clogging of the fins 15 caused by dust or the like can be prevented.

The configuration of the refrigerator 1 exemplified in the embodiment is an example, and the number of the storage compartments 10 may be different, or the function or arrangement may be different. For example, a freezer compartment or the like is provided at the lowermost portion. Further, for example, FIG. 2 and the like schematically show a configuration or a structure. For example, the size or installation portion of the compressor 11 and the condenser 12, the cooling fan 20, the opening portion 9, and the like may not necessarily be illustrated.

Further, as shown in FIG. 25, the refrigerator 1 in which the machine room 8 is provided in the upper portion of the main body 2 may be used. That is, the shape of the machine room 8 or the arrangement in the body 2 is not limited to the shape or arrangement exemplified in the embodiment. In the case of FIG. 25, the header 13 on the inlet side is directed toward the upper portion, and the header 13 on the outlet side is directed toward the lower portion. When viewed from the side of the left side plate 4, the condenser 12 is substantially oriented toward FIG. (a) The arrangement direction shown, whereby the influence on the storage compartment 10 can be suppressed, and space can be saved.

Further, as shown in Fig. 27, the heat insulating member 30 may be provided between the condenser 12 and a wall portion provided with the installation portion of the condenser 12, for example, the heat insulating partition wall 10b of the machine room 8, the partition The heat member 30 blocks a space between the condenser 12 and the heat insulating partition wall 10b, or at least a portion of the space. In this way, for example, in the case where it is necessary to arrange the inlet-side connecting pipe 16a having a relatively high temperature on the side of the heat insulating partition wall 10b in consideration of the piping, it is possible to suppress the transfer of heat from the condenser 12 to the storage compartment 10. Further, the heat insulating member 30 may be provided in a space above the condenser 12.

In this manner, the heat insulating member 30 is provided in a state in which the space between the condenser 12 and the heat insulating partition wall 10b is blocked, whereby the inflow of air into the space between the condenser 12 and the heat insulating partition wall 10b can be suppressed. In other words, the wind delivered by the cooling fan 20 can be concentrated on the condenser 12 in an effective manner. Thereby, the condenser 12 can be efficiently cooled.

Further, as shown in FIG. 28, the condenser 12 may be disposed in a state in which a wall portion of the installation portion of the condenser 12, for example, the heat insulating partition wall 10b of the machine room 8 is provided. In this case, it is preferable to arrange the outlet-side connecting pipe 16b having a relatively low temperature on the side of the heat insulating partition wall 10b. Thereby, it is possible to suppress the transfer of heat from the condenser 12 to the storage chamber 10. Further, the condenser 12 is disposed in a state in which the condenser 12 is in contact with the heat insulating partition wall 10b, whereby air inflow into the space between the condenser 12 and the heat insulating partition wall 10b can be suppressed, and the cooling fan 20 can be transported. The wind is concentrated in the condenser 12, so that the condenser 12 can be efficiently cooled. In this case, the heat insulating member 30 may be provided at a portion other than the contact portion.

Further, when the machine room 8 is provided in the upper portion of the main body 2 as shown in Fig. 25, as shown in Fig. 29, the wall portion of the upper and lower sides of the condenser 12 and the wall on the top side of the tank may be provided. The state of the contact is configured. In this case, the outlet side connecting pipe 16b having a relatively low temperature is disposed inside the tank, whereby the transfer of heat to the storage compartment 10 can be suppressed, and the inlet side connecting pipe 16a having a relatively high temperature can be brought into contact with the top plate side. Thereby, it is also possible to promote heat dissipation from the handcuff side.
