A fin (36) of a heat exchanger (30) includes: a plurality of intermediate plates (70) arranged one above another and dividing a space between adjacent ones of flat tubes (33) into air passages (40); a plurality of tube insertion portions (46) each provided between vertically adjacent ones of the intermediate plates (70), with an upwind side thereof being open such that a corresponding one of the flat tubes (33) is inserted therein; a vertically extending downwind plate (75) that is continuous with downwind ends of the plurality of intermediate plates (70) arranged one above another; and a plurality of upwind plates (77) extending further toward an upwind side than the flat tubes (33) from upwind side ends of the intermediate plates (70). Each of the upwind plates (77) is provided with at least one upwind side heat-transfer portion (81, 91, 92, 95) which projects toward the air passages (40). |
