Abstract

The present invention provides a plate-fin stacked heat exchanger, which is constituted by stacking plate fins (2a) each having a plurality of heat transfer passages (14) through which a first fluid flows in parallel. 2a) Heat exchange is performed between the second fluid flowing therebetween and the first fluid. Each of the plate fins (2a) forms a plurality of heat transfer flow paths (14) by means of concave grooves provided on the plates (6a, 6b) arranged opposite to each other, including a plurality of heat transfer flow paths (14) communicated with The liquid side header flow path and the gas side header flow path (10), and the communication flow path (11) connecting multiple heat transfer flow paths and the gas side header flow path (10), the communication flow path ( 11) The cross-sectional area is not more than the total cross-sectional area of ​​the plurality of heat transfer channels (14).

Description

technical field [0001] The present invention relates to a plate-fin laminated heat exchanger and a refrigeration system using it. Background technique [0002] Generally, in a refrigeration system such as an air conditioner or a refrigerator, refrigerant compressed by a compressor circulates through a heat exchanger such as a condenser or an evaporator, and exchanges heat with a second fluid to perform cooling or heating. In this case, the performance and energy saving of the system are largely determined by the heat exchange efficiency of the heat exchanger. Therefore, there is a strong demand for high efficiency of heat exchangers. [0003] As a heat exchanger of a refrigeration system such as an air conditioner or a refrigerator, a fin-and-tube heat exchanger is generally used in which a heat transfer tube is penetrated in a group of fins, and since the diameter of the heat transfer tube is reduced, Improvement in heat exchange efficiency and progress in miniaturization...
