Definitions
- the present invention relates to an air-cooled heat exchanger that is mainly mounted under the floor of an automobile or at the lower part of an engine room, particularly under an engine front.
- Patent Document 1 a heat exchanger in which corrugated fin members are arranged on a meander-formed tube member has been known.
- This heat exchanger can be made compact by forming the pipe member in a meandering manner, making it possible to lengthen the flow path of the fluid flowing through the inside of the pipe member, and by using corrugated fin members, a large number of pipe members can be used. It is possible to arrange the fins, and the heat exchange performance can be improved.
- the pipe member is formed in a meandering manner to reduce the bulk of the heat exchanger in the thickness direction, so that the floor of an automobile or the lower part of an engine room is formed.
- the stepping stones from the road surface are in direct contact with the pipe member and damaged during traveling, and stress concentration occurs in the recess formed by this damage due to external force due to vibration, etc.
- An object of the present invention is to obtain a heat exchanger capable of preventing a situation where a pipe member is damaged.
- the present invention repeatedly folds and stacks plate materials into a corrugated shape to form corrugated fins, and press-deforms the curved portion formed by the bending processing into a concave shape.
- a plurality of fin members formed with engaging recesses, and a plurality of straight pipe portions arranged in parallel via the fin members and the straight pipe portions having meandering pipe members having U-shaped folded portions.
- the plurality of straight pipe portions of the pipe member are engaged with the engagement concave portions of the plurality of fin members.
- the present invention is such that a fin member formed of corrugated fins is assembled to a meandering tube member in which a plurality of straight pipe portions are integrally formed. It can arrange
- the fin member is formed of corrugated fins, the surface area of the fin member can be increased due to the presence of the curved portion formed between the fins of the corrugated fin. Therefore, it is possible to efficiently dissipate heat from the pipe member, and heat exchange performance can be improved.
- a one-stage heat exchanger different from the two-stage heat exchanger described in Patent Document 1 is formed. Can be easily mounted under the floor.
- the outer diameter of the pipe member is 8 mm to 12 mm.
- the outer diameter of the pipe member is less than 8 mm, especially when a liquid such as oil, gasoline, or light oil is used as the fluid in the pipe, it becomes difficult to ensure the required flow rate because the pressure loss of the fluid increases. The flow rate decreases and it becomes difficult to obtain a desired amount of exchange heat, or the pressure loss exceeds a threshold value and it becomes impossible to use.
- the diameter is larger than 12.0 mm, the outer diameter of the pipe member is increased. Therefore, although the required flow rate of the fluid is easily secured as the outer diameter increases, the entire product becomes bulky and the automobile As a result, the mountability in a narrow space such as under the floor of the vehicle or in the lower part of the engine room is reduced.
- the facing interval between the curved tops that protrude outwardly at the curved portions of the adjacent fin members is set to 0.5 to 5.0 mm.
- the curved top part in this invention means the top part most projected in the bending width direction of the fin member in the curved part of the fin member curvedly formed by the bending process of a board
- interval is larger than 5.0 mm, it becomes necessary to arrange
- the facing distance between the adjacent fin members becomes narrow, so that the stepping stones from the road surface are less likely to enter the facing distance, and the stepping stones are on the surface of the pipe member during traveling. Since the tube member surface is damaged by stepping stones and a recess is formed, and the recess is prevented from being damaged due to stress concentration due to external forces such as vibration. Is preferable. However, in order to make the facing interval less than 0.5 mm, the protruding portions of adjacent fin members must be arranged close to each other.
- the facing interval means a disposition interval between adjacent fin members facing each other through the tube member, and in particular, an engagement recess that does not involve the tube member between both fin members. It means an interval at the curved top protruding from the fin member in the width direction.
- the protruding height in the width direction of the fin member from the surface of the straight pipe portion of the pipe member is set to 11 mm or less.
- the reason for this is that if the protrusion height in the width direction of the fin member is larger than 11 mm, the entire product assembled with the fin member becomes bulky, and the mountability to an automobile or the like is reduced. From the calculation of the fin efficiency of the fin member shown, it became clear that a significant improvement in heat exchange performance cannot be expected.
- the relationship between the protrusion height of a fin member and the fin efficiency regarding the heat exchange performance of a fin member is demonstrated below.
- the said fin efficiency means the heat dissipation efficiency of the fin member which changes with the shape of a fin member, the height of a fin member, and the plate
- the protrusion height in the width direction of the fin member exceeds 11 mm, the fin efficiency is lower than 80%, and the heat exchange efficiency is lowered, while the protrusion height of the fin member is 11 mm or less.
- the fin efficiency can be secured at 80% or more, and the heat exchange efficiency can be maintained well. Therefore, in order to maintain the heat exchange efficiency of the present invention satisfactorily, the protrusion height in the width direction of the fin member needs to be 11 mm or less.
- the protrusion height in the width direction of the fin member is limited to 11 mm or less, and in the present invention, the protrusion height of the fin member is set such that the facing interval between the curved top portions is 0.5 to 5.0 mm.

- the limit value of the shortest distance between the pipe member (1) and the stepping stone (21) when the stepping stone (21) does not directly hit the pipe member (1). If the distance between the tube member and the stepping stone is at least 1 mm or more in the schematic diagram, it is assumed that the stepping stone does not directly hit the tube member even during actual travel.
- each facing distance t and the protrusion in the width direction of the fin member when the facing distance t is 0.5 mm, 1 mm, 4 mm, and 5 mm.
- FIGS. 6A to 6D regarding the relationship with the height L, a schematic diagram was created for each facing interval, and a simulation analysis was performed.
- the facing interval t is 0.5 mm in (a)
- the facing interval t is 1 mm in (b)
- the facing interval t is 4 mm in (c)
- the facing interval t is 5 mm in (d).
- a schematic diagram is shown respectively.
- the shortest distance P of a stepping stone (21) and the surface of a pipe member (1) will be 1 mm, ie, the protrusion height L of the fin member that a stepping stone does not hit a pipe member directly.

- interval t was made into the minimum value of the protrusion height of the fin member in which a stepping stone does not directly hit the surface of a pipe member in each opposing space
- the protrusion height in the width direction of the fin member is y ⁇ 2.46x ⁇ .
- the fin member may have a plate thickness of 0.2 mm to 0.5 mm. If the plate thickness is less than 0.2 mm, the fin member becomes thin, so the heat capacity of the fin becomes poor, the temperature of the fin decreases rapidly, the heat exchange efficiency decreases, and the strength of the fin decreases. This makes it easier for the stepping stones to come into contact with the surface of the pipe member. If the thickness is greater than 0.5 mm, the strength is improved, but the heat exchange efficiency is somewhat improved, but a significant improvement cannot be expected, so the material is wasted.
- the fin member may have a fin arrangement interval of 1.6 mm to 2.2 mm formed by bending.

From FIG. 8, it was found that the drop temperature of the fluid in the tube exceeds about 10 ° C. when the arrangement interval is in the range of 1.6 mm to 2.2 mm. From this result, it can be seen that in the range where the fin arrangement interval is 1.6 mm to 2.2 mm, the drop temperature of the fluid in the pipe accompanying the passage to the heat exchanger shows a higher value than other arrangement intervals. In order to maintain good heat exchange performance of the members, it is preferable that the fin spacing be in the range of 1.6 mm to 2.2 mm.
- the fin arrangement interval is less than 1.6 mm, the surface area of the fin member increases, but the arrangement interval becomes too narrow, so that the flow resistance increases and the fluidity of the fluid passing through the fin member is poor.
- the heat exchange performance will be reduced, and if it is larger than 2.2 mm, the flow resistance will decrease and the flow will be easier, but the surface area of the fin member will be smaller, so in this case also the heat exchange performance Decreases.
- the present invention is configured as described above, and the fin member formed as a corrugated fin is engaged with the meandering tube member, the manufacturing can be facilitated, and the fin member The surface area of the tube member can be increased, and the heat from the tube member can be efficiently radiated.
- the stepping stone from the road surface directly hits the surface of the pipe member during traveling without impairing good heat exchange performance.
- the abutting part of the tube member is damaged and a recess is formed. In this recess, stress concentration due to external forces such as vibration occurs, and the risk of damaging the tube member can be eliminated, and the bulk of the product in the thickness direction can be reduced. Can be low. Therefore, it is possible to improve the mountability in a narrow space under the floor of an automobile or at the lower part of the engine room, particularly under the engine front.
