Problems solved by technology
[0006] In the field of heat exchangers, forming plate fins from a material with a thin thickness and high thermal conductivity is advantageous in terms of weight reduction, miniaturization, and efficiency improvement, but there may be problems in terms of reliability
In particular, in the case of providing a structure in which high-pressure refrigerant flows through the flow paths formed in the plate fins, there is a possibility that the flow paths of the refrigerant in the plate fins may be deformed, resulting in a change in the flow rate and velocity of the refrigerant. unevenness, resulting in reduced performance as a heat exchanger
In addition, in some cases, there is a problem that the refrigerant leaks from the refrigerant flow path in the thin plate fin.

Embodiment Construction
[0043] The heat exchanger according to the first aspect of the present invention includes: a plate-fin laminate formed by laminating a plurality of plate fins, wherein the plate fins have a flow path in which a first fluid flows; and the plate-fin laminates are provided The end plates at both ends of the stacking direction of the body; and the supply and discharge pipe, which is connected to the end plate, and the first fluid flowing in the flow path of each plate fin in the plate fin laminate passes through the supply and discharge pipe. In this heat exchanger, the second fluid is caused to flow between the stacks of the plate-fin laminate, and heat is exchanged between the first fluid and the second fluid. The plate fin includes two plate-shaped members having concave surfaces constituting the flow path at opposite positions, and the flow path is formed by the concave surfaces of the two plate-shaped members that are fixed to each other oppositely. One of the plate-shaped mem...

A heat exchanger according to a first aspect of the present invention includes a plate-fin laminate, an end plate, and a supply and discharge pipe through which a first fluid passes. The plate fin includes two plate-shaped members having concave surfaces constituting a flow path at opposing positions, and the flow paths are formed by the respective concave surfaces of the two plate-shaped members fixed to face each other. One of the plate members is disposed at a position facing the end plates of the plate-fin laminated body. One plate-shaped member arranged to face the end plate is provided so that the surface having the concave surface is in contact with the end plate.
Description
Technical field [0001] The present invention relates to a heat exchanger, and more particularly, to a laminated plate fin heat exchanger formed by laminating plate-shaped plate fins through which refrigerant flows. Background technique [0002] Heat exchangers for exchanging heat energy between fluids with different heat energy are used by a large number of equipment. In particular, laminated plate-fin heat exchangers are widely used, for example, in air conditioners, computers, and various electrical equipment for households and vehicles. [0003] The heat exchanger with laminated plate fins exchanges heat between the fluid (refrigerant) flowing in the flow path formed in the plate fins and the fluid (air) flowing between the laminated plate fins form. [0004] In the field of the above-mentioned laminated plate-fin heat exchanger, various structures have been proposed for the purpose of weight reduction, miniaturization, and efficiency of heat exchange (for example, refer to Pate...
