To provide an outdoor heat exchanger which is improved in the drain performance of defrosted water from a heat exchanger main body at a defrosting operation mode.SOLUTION: An outdoor heat exchanger 4 is composed of a heat exchanger main body 40 comprising a heat exchange core part 43 having a plurality of heat exchange pipes 46 and fins 47, and a defrosted water drainage drain promotion material 50 arranged at a front side of the heat exchange core part 43 of the heat exchanger main body 40. The drain promotion material 50 is formed into a net shape by combining a plurality of sets of linear members 51, 52 and 53. At least a part of the drain promotion material 50 contacts with the heat exchange core part 43, or approximates it, and water is induced by surface tension from at least either of the heat exchange pipes 46 and the fins 47 of the heat exchange core part 43. Capillary grooves 54 opened at the heat exchange core part 43 side of the heat exchanger main body 40 are formed at the drain promotion material 50 so as to be stretched around all the linear members 51, 52 and 53, and to form the net shape.SELECTED DRAWING: Figure 2
【課題】除霜運転モード時における熱交換器本体からの解霜水の排水性が向上した室外熱交換器を提供する。【解決手段】室外熱交換器4は、複数の熱交換管46とフィン47を有する熱交換コア部43を備えた熱交換器本体40と、熱交換器本体40の熱交換コア部43の前側に配置された解霜水排水用の排水促進部材50とからなる。排水促進部材50が、線状部材51,52,53を複数組み合わせることにより網目状に構成されている。排水促進部材50の少なくとも一部が、熱交換コア部43に接触し、または近接し、かつ熱交換コア部43の熱交換管46およびフィン47のうちの少なくともいずれか一方から表面張力により水を誘引する。排水促進部材50に、熱交換器本体40の熱交換コア部43側に開口した毛細溝54が、全線状部材51,52,53に張り巡らされて網目状となるように形成されている。【選択図】図2
