Abstract

A heat exchanger and an air conditioner indoor unit, where heat-exchanging ability is prevented from falling and the tolerance for installation angle of a heat-exchanging portion can be relaxed. An indoor heat exchanger (50) is constructed from plural heat exchangers that are joined together and provided in an air conditioner indoor unit (2). The heat exchangers are a first indoor heat exchanger (50a), a second indoor heat exchanger (50b), a third indoor heat exchanger (50c), and a fourth indoor heat exchanger (50d). The third indoor heat exchanger (50c) is joined at an angle to one end of the first indoor heat exchanger (50a) and second indoor heat exchanger (50b). The fourth indoor heat exchanger (50d) is joined at an angle to the other end of the first indoor heat exchanger (50a) and second indoor heat exchanger (50b). The third indoor heat exchanger (50c) and fourth indoor heat exchanger (50d) have substantially the same length.
