Abstract (en)
[origin: WO2022224350A1] This heat exchanger comprises: a first heat exchanger that exchanges heat between air and refrigerant; and a second heat exchanger that is disposed in series with the first heat exchanger in a first direction, which is the air flow direction, and exchanges heat between air and the refrigerant. The first heat exchanger has a plurality of first heat exchanger tubes that are spaced apart from each other in a second direction intersecting the first direction and circulate the refrigerant therethrough. The axial direction of the first heat exchanger tubes extends along a third direction that intersects each of the first and second directions. The second heat exchanger has a plurality of second heat exchanger tubes that are spaced apart from each other in the second direction and circulate the refrigerant therethrough, and a corrugated fin that is provided between the plurality of second heat exchanger tubes. The axial direction of the second heat exchanger tubes extends along the third direction.
