Abstract:
This heat exchanger (7) comprises a plurality of flat heat transfer tubes (23) which respectively have formed therein a plurality of first flow passages (35) and a plurality of second flow passages (34), and a header (21) having formed therein an insertion space (53). The header (21) has: a tube pass-through wall portion (68) through which the plurality of flat heat transfer tubes pass so that the plurality of flow passages (35) are connected to a first space (62) in the insertion space and the plurality of second flow passages (34) are connected to a second space (61) in the insertion space; a protruding wall (45) that divides the insertion space into the first space (62) and the second space (61); and an inflow part (67) which supplies a refrigerant to the first space (62) so that the refrigerant flows toward an inner wall surface (65) that is in contact with the first space (62) in the tube pass-through wall portion (68), wherein the protruding wall (45) is separated from the tube pass-through wall portion (68) so that a communication passage (63) through which the refrigerant flows from the first space (62) to the second space (61) is formed between the protruding wall (45) and the tube pass-through wall portion (68).
