To provide an outdoor heat exchanger which enables suppression of vertical dispersion of volume of air applied to a rear heat exchanger and which has improved heat exchange performance.SOLUTION: First heat exchange tubes 33 whose upper surfaces 33a are inclined downward from front ends to rear ends and whose lower ends 33b are inclined upward from the front ends to the rear ends and second heat exchange tubes 34 whose upper surfaces 34a are inclined upward from the front ends to the rear ends and whose lower surfaces 34b are inclined downward from the upper ends to the rear ends are alternately arranged in the vertical direction in a heat exchange core unit of an outdoor heat exchanger 11 of a heat pump type refrigeration cycle. Ventilation clearance 38 is constituted by the first and second heat exchange tubes 33, 34 adjacent each other in the vertical direction and a corrugate fin 39 is arranged in the ventilation clearance 38. The upper surface 33a of the first heat exchange tube 33 and the lower surface 34b of the second heat exchange tube 34 are parallel with each other, and the lower surface 33b of the first heat exchange tube 33 and the upper surface 34a of the second heat exchange tube 34 are parallel with each other.SELECTED DRAWING: Figure 4
【課題】後側熱交換器に当たる空気量の上下方向のばらつきを抑制しうるとともに、熱交換性能が向上した室外熱交換器を提供する。【解決手段】ヒートポンプ式冷凍サイクルの室外熱交換器11の熱交換コア部に、上面33aが前端から後端に向かって下方に傾斜するとともに、下面33bが前端から後端に向かって上方に傾斜した第1熱交換管33と、上面34aが前端から後端に向かって上方に傾斜するとともに、下面34bが前端から後端に向かって下方に傾斜した第2熱交換管34とが上下方向に交互に並んで配置されている。上下方向に隣接する第1および第2熱交換管33,34により通風間隙38が構成され、通風間隙38にコルゲートフィン39が配置されている。第1熱交換管33の上面33aと第2熱交換管34の下面34b、および第1熱交換管33の下面33bと第2熱交換管34の上面34aとがそれぞれ平行になっている。【選択図】図4
