Abstract (en)

[origin: JP2018124047A] PROBLEM TO BE SOLVED: To increase a heat transfer area between a refrigerant pipe and a corrugated fin, to improve heat transfer performance in a heat exchanger.SOLUTION: A heat exchanger includes: a refrigerant pipe formed in a multistage manner by being folded in a meander manner; and a plurality of corrugated fins arranged in each of a plurality of stages formed in the refrigerant pipe, and into which the refrigeration pipe is inserted on each stage. Each corrugated fin has, for example, collars 133f, 134f that are members provided at insertion holes 131f, 132f into which the refrigerant pipe of each corrugated fin is inserted, and that are members for making the refrigerant pipe bring into surface contact with each corrugated fin.SELECTED DRAWING: Figure 4
