Abstract:
According to the present invention, an outdoor heat exchanger (9) is provided with: a primary heat exchanger (11) equipped with a first heat transfer pipe (21); and a secondary heat exchanger (12) equipped with a second heat transfer pipe (23). A flow passage part (30) in which a refrigerant flows is provided between one end side of the first heat transfer pipe (21) and one end side of the second heat transfer pipe (23). The flow passage part (30) is formed by a plate-like body (31), a plate-like body (32), and a plate-like body (33). The plate-like body (31) has formed therein inflow/outflow holes (51, 53). The plate-like body (32) has formed therein refrigerant passages (41, 42). The lower end sides of the refrigerant passages (41, 42) communicate with the inflow/outflow holes (53) and the upper end sides communicate with the inflow/outflow holes (51). The plate-like body (33) is stacked on the plate-like body (32) so as to cover the refrigerant passages (41, 42) from the opposite side, with respect to the plate-like body (32), of the side on which the refrigerant passages (41, 42) communicate with the inflow/outflow holes (51, 53).
