Abstract (en)

The accumulation of lubricating oil within a header is suppressed in a configuration including a plurality of heat transfer pipes. A heat exchanger 10A includes a plurality of heat transfer pipes 11 that are provided at intervals in a vertical direction and allow a refrigerant to flow therethrough toward first ends; and a header 20A that extends in the vertical direction, has the first ends of the plurality of heat transfer pipes 11 connected thereto, and allows the refrigerant to flow from a lower end 20s toward an upper end 20t to which a refrigerant pipe 4 is connected. A flow passage cross-sectional area of a portion of the header 20A to which a heat transfer pipe 11A located at a lowermost stage among the plurality of heat transfer pipes 11 is connected is smaller than a flow passage cross-sectional area at the upper end 20t of the header 20A.
