(54) HEAT EXCHANGER


(57) A heat exchanger (10) includes a plurality of flat tubes (20) and one or more fins (30). The flat tubes (20) are arranged in a first direction. The fin (30) is joined to the flat tubes (20). The heat exchanger (10) causes heat exchange between a refrigerant that flows inside the flat tubes (20) and air that flows outside the flat tubes (20) along a second direction that intersects the first direction. The fin (30) includes a first joint portion (32) and a first plate portion (33). The first joint portion (32) is joined to a first flat tube (20a). The first plate portion (33) is positioned between an air flow downstream end (30b) and the first joint portion (32). The first plate portion (33) is formed with a first protruding portion (133) for causing water to flow in the first direction in a vicinity of the first flat tube (20a).
