    • 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。
