HEAT EXCHANGER

WIPO Patent Application WO/2022/014516

A1

Provided is a compact and high-performance heat exchanger that has a curved part provided to a header thereof. A heat source heat exchanger (50) comprises a liquid header (54) and a plurality of flat heat-transfer pipes (60). The liquid header includes at least a first straight part (54a) extending in the left-right direction, a second straight part (54b) extending in the front-back direction that is orthogonal to the left-right direction, and a curved part (54c). The curved part connects the first straight part and the second straight part. The plurality of flat heat-transfer pipes are respectively inserted into openings formed in the liquid header, and are connected to the liquid header. The flat heat-transfer pipes include curved part flat pipes (66) that are inserted into and affixed to the openings provided in the curved part. A cross-sectional longitudinal direction of the curved part flat pipes is inclined relative to both a cross-sectional longitudinal direction of first flat pipes (62) inserted into and affixed to the openings provided in the first straight part, and a cross-sectional longitudinal direction of second flat pipes (64) inserted and affixed to the openings provided in the second straight part.
