Description

[Detailed description of the invention]

The present invention relates to a refrigerator in which heat radiation from a condenser is supplemented by a heat storage device. Conventionally, in the refrigeration cycle used in refrigerators, a condenser consisting of a meandering pipe is used to condense the cold soot emitted from the compressor, which is the basic part of the refrigeration cycle, and a large number of heat dissipation wires attached to the condenser are used to condense the cold soot emitted from the compressor. It is designed to dissipate heat. However, such a device that radiates heat only from the condenser has the disadvantage that the condenser requires extremely long pipe materials such as meandering pipes as mentioned above, and there is also the trouble of complicated bending, and it also requires a large number of radiating fins. was there. The present invention has been made in view of the above-mentioned circumstances, and its purpose is to radiate the necessary amount of heat with a simple device such as a condenser, and to improve the heat radiating performance. To provide an extremely high-performance refrigerator capable of improving its heat dissipation performance throughout the year. Hereinafter, one embodiment of the present invention will be explained with reference to the drawings. First, in FIG. 1, 1 is the refrigerator main body, 2 is the freezer compartment inside, 3 is the refrigerator compartment, 4 is the freezer compartment door, 5 is a refrigerator compartment door. On the other hand, 6 is a compressor installed in the lower back side (machine room) of the storage body 1, and 7 is a condenser (condensation pipe) extending from this compressor 6. As shown in FIG. 2, they are arranged in a so-called inverted U-shape around the back surface of the refrigerator main body 1, in close contact with the inner surface of the heat-conductive back plate la. Reference numeral 8 denotes a heat storage device disposed at the center of the back of the main body 1 surrounded by the condenser 7, and in detail, as shown in FIGS. 3 and 4, a flat substrate 9 and a corrugated plate 10 The phase change temperature is 15 to 20 degrees inside the heat transfer container 11 which is formed into a so-called single-sided corrugated board shape by laminating

For example, i-A skin NCH02 of [00]
The heat storage agent 12 consists of 40 days and 20 days, and the phase change temperature is 20~
For example, Mgc121 mother at 30 [℃] is also ○ and Cac12
・Heat storage agent 13 consisting of a mixture of mother LO and a phase change temperature of 29 to 39

[00], for example, a heat storage agent 1 to 4 made of Cad 2 and Fine 20, is sequentially sealed in each corrugated portion of the corrugated plate 10, and based on this structure, the substrate 9
is brought into close contact with the inner surface of the back plate la and is fixed by a presser metal fitting 15. Now, according to this embodiment configured as described above, heat is radiated from the condenser 7 to the outside of the refrigerator via the peripheral part of the back plate la, and heat is also radiated from the peripheral part of the back plate la to the central part. Heat is also radiated to the heat storage device 8 through the exposed part.
That is, this heat storage device 8 absorbs a large amount of heat from the condenser 7, and radiates the absorbed heat when the operation is stopped, so that the back plate l
The back plate la including not only the peripheral part of a but also the central part
The heat is dissipated from the entire surface of the condenser, thus achieving a greater heat dissipation effect than before, and the condenser 7 can therefore be kept to a very simple pipe with an inverted U-shape. The design, manufacturing, and installation effort can all be greatly simplified. By the way, the temperature of the room in which the refrigerator is installed varies widely throughout the year, ranging from approximately 10 to 30 degrees Celsius. Accordingly, the condensation temperature of the medium in the refrigerator also varies from room temperature to 10 degrees Celsius. If the temperature is about 14 to 22, the room temperature is 20.

[00] is about 23-34

[00], the room temperature is 30 [
℃] is about 34-44

Changes to [00]. For this reason, if a single type of heat storage agent whose phase change temperature is unique is used in the heat storage device 8, even if it can handle one of the above temperatures, it will not be able to handle the remaining temperatures, resulting in a drawback. However, in this example, as mentioned above, the phase change temperature was 15 to 20 degrees, 20 to 30 degrees, and 29 degrees
Since different types of heat storage agents 12, 13, and 14 are sealed and used, the heat storage agents 12, 13, and 14 are used by enclosing different types of heat storage agents 12, 13, and 14. 12, 13, 14 corresponds,
Therefore, it is possible to improve the heat dissipation effect throughout the year and to achieve highly efficient operation of the refrigerator, which is extremely effective in achieving so-called high performance. In the above embodiment, the condenser 7 and the heat storage device 8 are provided inside the husband's back plate la, but they may be provided outside the husband's back plate la.
It may be provided on a surface other than the back plate la. In addition, the present invention is not limited to the embodiments described above and shown in the drawings, but in particular, the specific shape of the condenser, the specific types and number of heat storage agents, or the specific types and enclosure structure of each of them. etc., may be modified and implemented as appropriate within the scope of the gist. In summary, the present invention comprises a heat storage device having a plurality of types of heat storage agents having different phase change temperatures, which are attached together with a condenser to any one surface of the refrigerator body so that heat can be conducted through each surface. It is characterized by the fact that a simple condenser can be used to radiate the necessary amount of heat, and it is also possible to improve the heat radiating performance. It is possible to provide an extremely high-performance refrigerator that can be improved through the use of a refrigerator.
