HEAT EXCHANGER AND AIR CONDITIONER

摘要

A first main communication space (75a) which communicates with the upstream side of a plurality of flattened tubes (31) during functioning of the outdoor heat exchanger as an evaporator is provided with a partition plate (91) extending in the vertical direction, and partitioning the first main communication space (75a) into a first space (93) through which the first main communication space (75a) communicates with the plurality of flattened tubes (31), and a second space (94) which communicates with a branched tube part (112a) for introducing a refrigerant into the first main communication space (75a) during functioning of the outdoor heat exchanger as an evaporator. A through-hole (91a) through which the first space (93) and the second space (94) communicate is formed below the first main communication space (75a).
