<p>A heat exchanger (30) has flat tubes (33) arranged vertically, and plate-shaped fins (36) arranged in the extension direction of the flat tubes (33). The flat tubes (33) are inserted into notched sections (45) in the fins (36). The section between vertically adjacent notched sections (45) of the fins (36) is a windward plate section (70), while the section on the leeward side of each notched section (45) is a leeward plate section (75). A windward-side heat conduction promotion unit (71) comprising projecting parts (81-83) and louvers (50a, 50b) is provided on the windward plate section (70). A leeward-side heat conduction promotion unit (76) comprising a leeward-side projecting part (84) is provided on the leeward plate section (75). The leeward-side heat conduction promotion unit (76) is positioned on the leeward side of the notched section (45), and overlaps with the windward-side heat conduction promotion unit (71) when viewed from the fin (36) leading edge (38) side.</p> |
