To provide an outdoor heat exchanger for a heat pump-type refrigeration cycle capable of retarding degradation of heat exchange efficiency in heating.SOLUTION: An outdoor heat exchanger 4 includes a plurality of flat refrigerant circulation tubes 39, and fins 42 arranged in a ventilation clearance 41 between the adjacent refrigerant circulation tubes 39. Each of the fin 42 is composed of a main heat exchange portion 44 positioned within a range in a ventilation direction, of the ventilation clearance 41, and a projecting portion 45 disposed integrally with the main heat exchange portion 44, and projecting to a windward side with respect to the refrigerant circulation tubes 39. The main heat exchange portion 44 and the projecting portion 45 have corrugated shape composed of wave top portions 44a, 45a, wave bottom portions 44b, 45b, and connecting portions 44c, 45c connecting the wave top portions 44a, 45a and the wave bottom portions 44b, 45b. First to fifth through holes 47, 48, 49, 51, 52 are formed on the projecting portion 45 of the fin 42.SELECTED DRAWING: Figure 3

    【課題】暖房時に、熱交換効率の低下を遅延させうるヒートポンプ式冷凍サイクル用室外熱交換器を提供する。【解決手段】室外熱交換器4は、複数の扁平状冷媒流通管39と、隣り合う冷媒流通管39どうしの間の通風間隙41に配置されたフィン42とを備えている。フィン42は、通風間隙41の通風方向の範囲内に位置するメイン熱交換部44と、メイン熱交換部44に一体に設けられ、かつ冷媒流通管39よりも風上側に突出した突出部45とからなる。メイン熱交換部44および突出部45は、波頂部44a,45a、波底部44b,45b、および波頂部44a,45aと波底部44b,45bとを連結する連結部44c,45cよりなるコルゲート状である。フィン42の突出部45に第1〜第5貫通穴47,48,49,51,52が形成されている。【選択図】図3
