To provide an outdoor heat exchanger which has an excellent water-drainage property of a defrost water and which can suppress increase in manufacturing cost, increase in coolant inclusion amount, and degradation in heat exchanging property.SOLUTION: An outdoor heat exchanger 11 includes: header tanks 30, 31 provided in a right-left direction with a space therebetween; and a heat exchanging core part 40 provided between the two header tanks 30, 31. The heat exchanging core part 40 includes a plurality of flat coolant flow pipes 41 and a plurality of fins 42. The coolant flow pipe 41 includes right and left inclined parts 411, 412 inclined diagonally downward from right and left end parts toward a middle part in the right-left direction and has a substantially V-shape where a connecting part of the right and left inclined parts 411, 412 is positioned at the lowest bottom. At a portion closer to a front end of an upper surface of the coolant flow pipe 41, a water drainage groove 416 is provided open upward and extending from a left end to a right end. A plurality of opening part for causing the water drainage groove 416 to communicate with a lower part of the coolant flow pipe 41 are formed in the coolant flow pipe 41 with a space therebetween in the right-left direction.SELECTED DRAWING: Figure 2
【課題】解霜水の排水性が優れているとともに、製造コストの増加、冷媒封入量の増大および熱交換性能の低下を抑制しうる室外熱交換器を提供する。【解決手段】室外熱交換器11は、左右方向に間隔をおいて配置されたヘッダタンク30,31と、両ヘッダタンク30,31間に設けられた熱交換コア部40とからなる。熱交換コア部40が、複数の扁平状冷媒流通管41およびフィン42を備えている。冷媒流通管41が、左右両端部から左右方向の中間部に向かって斜め下方に傾斜した左右両傾斜部411,412を有し、かつ左右両傾斜部411,412の連接部分が最も下方に位置する略V形である。冷媒流通管41の上面の前端寄りの部分に、上方に開口しかつ左端部から右端部に至る排水溝416が形成されている。冷媒流通管41に、排水溝416を冷媒流通管41の下方に通じさせる開口部が左右方向に間隔をおいて複数形成されている。【選択図】図2
