Title: HEAT EXCHANGER AND AIR CONDITIONER
Abstract:
Provided are a heat exchanger and an air conditioner capable of inhibiting uneven flow of refrigerant even when used under conditions when the circulation flow changes. A plurality of flat perforated pipes (21b) are connected at different heights to a first inner space (23a) of a return header collecting pipe (23) of an outdoor heat exchanger (20). The first inner space (23a) uses a loop structure that includes a first partitioning plate (51), a first inlet (41x), a first upper communicating route (51x), and a first lower communicating route (51y). The first partitioning plate (51) partitions the first inner space (23a) into a first outflow space (51a) and a first loop space (51b). The first inlet (41x) is provided at the bottom of the first outflow space (51a) so that the refrigerant rises in the first outflow space (51a). Refrigerant that reaches the upper end of the first outflow space (51a) is guided to the first loop space (51b) via the first upper communicating route (51x), and the refrigerant that drops from the first loop space (51b) is returned to the first outflow space (51a) in a non-vertical direction via the first lower communicating route (51y).
