To provide an outdoor heat exchanger that can reduce the number of components of a heat pump type refrigeration cycle, simplify the whole structure, and restrain a decrease in performance during cooling operation.SOLUTION: An outdoor heat exchanger 4 comprises: a first heat exchange part 30; a second heat exchange part 40 provided on the downstream side in the refrigerant flow direction of the first heat exchange part 30, and into which a refrigerant having passed through the first heat exchange part 30 flows; and a gas-liquid separator 50 provided on the downstream side in the refrigerant flow direction of the second heat exchange part 40, into which the refrigerant flows from the second heat exchange part 40, for separating the refrigerant having flowed in, into two phases of gas and liquid. The first heat exchange part 30 comprises a plurality of first heat exchange pipes 33 whose longitudinal direction is directed in the up-down direction. The second heat exchange part 40 comprises a plurality of second heat exchange pipes 43 whose longitudinal direction is directed in the left-right direction. The gas-liquid separator 50 comprises a liquid-phase refrigerant outlet 56 for sending a liquid-phase refrigerant during cooling operation of the heat pump type refrigeration cycle, and a gas-phase refrigerant outlet 55 for sending a gas-phase refrigerant during heating operation of the heat pump type refrigeration cycle.SELECTED DRAWING: Figure 3

    【課題】ヒートポンプ式冷凍サイクルの構成部品の数を少なくして全体の構成が簡易になり、しかも冷房運転時の性能低下を抑制しうる室外熱交換器提供する。【解決手段】室外熱交換器4は、第1熱交換部30と、第1熱交換部30の冷媒流れ方向下流側に設けられかつ第1熱交換部30を通過した冷媒が流入する第2熱交換部40と、第2熱交換部40の冷媒流れ方向下流側に設けられ、かつ冷媒が第2熱交換部40から流入するとともに流入した冷媒を気液2相に分離する気液分離器50とを備えている。第1熱交換部30が長手方向を上下方向に向けた複数の第1熱交換管33を有し、第2熱交換部40が長手方向を左右方向に向けた複数の第2熱交換管43を有し、気液分離器50が、ヒートポンプ式冷凍サイクルの冷房運転時に液相冷媒を送り出す液相冷媒出口56およびヒートポンプ式冷凍サイクルの暖房運転時に気相冷媒を送り出す気相冷媒出口55を有している。【選択図】図3
