    • If a forced convection is generated by a cooling fan, there is generated a problem that a natural convection is prevented and a cooling effect in a region of the natural convection is lowered. The invention provides a structure in which an air flow generated by a forced convection does not come into contact with an air flow generated by a natural convection, by setting a partition all between a forced convection path in which the air flows on the basis of a forced convection generated by a cooling fan, and a natural convection path in which the air flows on the basis of a natural convection. Further, the partition wall is not provided near an upper end so as to draw in the air flowing through the natural convection path to a side of the forced convection path, thereby promoting the natural convection of the natural convection path.
    • 如果由冷却风扇产生强制对流,则产生防止自然对流并降低自然对流区域的冷却效果的问题。 本发明提供了一种结构,其中通过强制对流产生的气流不会与由自然对流产生的空气流接触,通过在空气流动的强制对流路径之间设置隔板 由冷却风扇产生的强制对流,以及空气基于自然对流流动的自然对流路径。 此外,分隔壁不设置在上端附近,以便将流过自然对流路径的空气抽吸到强制对流路径的一侧,从而促进自然对流路径的自然对流。

    • Provided is an air heat exchanger capable of preventing an increase in ventilation resistance and a decrease in heat exchange efficiency due to condensation water generated on surfaces of heat transfer fins, without increasing thermal resistance of flat tubes and the heat transfer fins, and preventing scattering of water droplets downwind from the heat transfer fins. In the air heat exchanger including a plurality of flat tubes 2 and heat transfer fins 5 provided between the flat tubes 2 and on which air is blown, the flat tubes 2 include water draining grooves 4 on side surfaces on which the heat transfer fins 5 are provided and the heat transfer fins 5 include water guiding grooves 6 communicating with the water draining grooves 4. At least a groove wall 40 on the upwind side of an air blowing direction 10 among groove walls forming the water guiding grooves 6 is provided from a position of the upwind side from the water draining grooves 4 to the water draining grooves 4. The water guiding grooves 6 extend toward the water draining grooves 4 along the groove wall 40 on the upwind side and an area of a cross section perpendicular to an extension direction decreases toward the water draining grooves 4.
    • 提供一种空气热交换器,其能够防止由于传热翅片表面产生的冷凝水导致的通风阻力增加和热交换效率降低,而不增加扁平管和传热翅片的热阻,并且防止散热 水滴从传热翅片向下风向。 在包括设置在扁平管2之间的多个扁平管2和传热翅片5的空气热交换器中,扁平管2包括在其上具有传热翅片5的侧表面上的排水槽4 传热翅片5包括与排水槽4连通的导水槽6.至少在形成导水槽6的槽壁中的吹风方向10的上风侧的槽壁40从位置 从排水沟4向排水槽4的上风侧。导水槽6沿着上下风向侧的槽壁40向排水槽4延伸,与延伸方向垂直的截面的区域 朝向排水槽4减少。
