Document Type and Number:
WIPO Patent Application WO/2021/255781
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a heat exchanger and a refrigeration cycle apparatus capable of suppressing the buckling of flattened tubes in the tube axial direction without impairing drainage and ventilation. A heat exchanger according to the present disclosure comprises: a plurality of heat transfer members (11) that are spaced apart from each other and arrayed in the first direction (X), extend in the second direction (Y), and circulate a refrigerant inside; a first header (12a) that extends in the first direction (X) and is connected to one end of each of the plurality of heat transfer members (11); a second header (12b) that extends in the first direction (X) and is connected to the other end of each of the plurality of heat transfer members (11); and a reinforcing member (20) that extends along the first direction (X) and the second direction (Y) and is equipped with openings (25). When the third direction (Z) is perpendicular to the first direction (X) and the second direction (Y), the reinforcing member (25) is disposed on at least one side of the plurality of heat transfer members (11) in the third direction (Z) and fixed to the first header (12a) and the second header (12b).
