    • In a casing, a printed circuit board is arranged such that a first side of the printed circuit board has a first angle of α° with respect to a first side surface plate. A cooling device is arranged to have a second angle of β with respect to the first side surface plate. Accordingly, an amount of cooling air flowing in and out via an air intake port and an air discharge port may be increased. Furthermore, by reducing the angle of the change in the flow direction of the cooling air flowing over the printed circuit board, the cooling air flowing over the printed circuit board may be made to efficiently flow through an air discharge port 119a. Furthermore, the efficiency with which a heat-generating component on the printed circuit board is cooled may be improved.
    • 在壳体中,印刷电路板布置成使得印刷电路板的第一侧相对于第一侧面板具有α°的第一角度。 冷却装置被布置成具有第二角度&bgr; 相对于第一侧面板。 因此,可以增加通过进气口和排气口流入和流出的冷却空气量。 此外,通过减少流过印刷电路板的冷却空气的流动方向的变化的角度,可以使流过印刷电路板的冷却空气有效地流过排气口119a。 此外,可以提高印刷电路板上的发热部件被冷却的效率。
