Title:
HEAT EXCHANGER AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/281655
Kind Code:
A1
Abstract:
A heat exchanger (HE) comprises: a first heat transmission part (31a) that includes a plurality of first heat transmission pipes (31); a second heat transmission part (32a) that includes a plurality of second heat transmission pipes (32); and a non-azeotropic mixture refrigerant that flows through the plurality of first heat transmission pipes (31a) of the first heat transmission part (31) and the plurality of second heat transmission pipes (32a) of the heat transmission part (32). The plurality of first heat transmission pipes (31a) of the first heat transmission part (31) and the plurality of second heat transmission pipes (32a) of the heat transmission part (32) are arranged in a single row. The first heat transmission part (31) and the second heat transmission part (32) are configured so that the non-azeotropic mixture refrigerant flows so as to only flow back once from the first heat transmission part (31) to the second heat transmission part (32).
