Abstract (en)

[origin: EP3306234A1] The accumulation of lubricating oil within a header (20A, 20D, 20E) is suppressed while suppressing the outflow of a refrigerant in a configuration including a plurality of heat transfer pipes (11, 11A, 11B, 11C). A heat exchanger (10A, 10B, 10C, 10D, 10E) includes a plurality of heat transfer pipes (11, 11A, 11B, 11C) that are provided at intervals in a vertical direction and allow a refrigerant to flow therethrough toward first ends (115); a header (20A, 20D, 20E) that extends in the vertical direction, has the first ends of the plurality of heat transfer pipes (11, 11A, 11B, 11C) connected thereto, and allows the refrigerant to flow from a lower end (20s) toward an upper end (20t) to which a refrigerant pipe (4, 4E) is connected; and a bypass pipe (30) that allows the lower end (20s) of the header (20A, 20D, 20E) and the refrigerant pipe (4, 4E) to communicate with each other. The length of the bypass pipe (30) is made longer than the length of a flow passage that leads from the lower end (20s) of the header (20A, 20D, 20E) through the upper end (20t) to a site to which the bypass pipe (30) of the refrigerant pipe (4, 4E) is joined.
