Description

第1および第2のファン8,8’が作動すると、吸入口80,80’周辺の空気が第1および第2のファン8,8’に取り込まれ、その空気が風として第1および第2の風路9,9’の長手方向に対して交差する方向に吐出口81,81’から風路9,9’内に送り出される。それに伴い配置空間B2には、吸気孔部20から外部の空気が流入する。 When the first and second fans 8 and 8 ′ are operated, the air around the suction ports 80 and 80 ′ is taken into the first and second fans 8 and 8 ′, and the air is used as the wind for the first and second fans. Are sent out from the discharge ports 81 , 81 ′ into the air paths 9, 9 ′ in a direction intersecting the longitudinal direction of the air paths 9, 9 ′. Accordingly, outside air flows from the intake hole 20 into the arrangement space B2.

上記第1および第2の風路9,9’は、第3の仕切板7Cの水平部分によって上段と下段とに分けられている。そのため、たとえば電気部品31からの熱によって暖められた下段の第1の風路9内の空気は、温度が高くなるほど上昇しがちになるものの、上段の第2の風路9’に侵入することなく速やかに外部に排出される。これにより、上段に位置するヒートシンク5と下段に位置する電気部品31とは、互いに熱の影響を受けずに第1および第2のファン8,8’からの風によって効率よく冷却される。 The first and second air passages 9, 9 ′ are divided into an upper stage and a lower stage by a horizontal portion of the third partition plate 7C. Therefore, for example, the air in the lower first air passage 9 heated by the heat from the electrical component 31 tends to rise as the temperature rises, but enters the upper second air passage 9 ′. It is quickly discharged outside. Thereby, the heat sink 5 located in the upper stage and the electrical component 31 located in the lower stage are efficiently cooled by the wind from the first and second fans 8 and 8 'without being affected by heat.

上記電源装置Aは、たとえば工場内の床面上に配置され、その床面付近には、粉塵が集まりやすく、より多くの粉塵を含む空気が存在する。このような状態において、第1および第2のファン8,8’が作動すると、上側よりも下側の第1のファン8の方が床面に近い空気を吸い込みがちとなる。その反面、下側の第1のファン8は、上側の第2のファン8’よりも風量小で吸気力も小さくなっている。これにより、下側の第1のファン8によって吸い込まれる粉塵の量が抑えられ、床面に近い下側の第1の風路9でも、第1のファン8からの粉塵の侵入が効果的に抑制される。 The power supply device A is disposed, for example, on a floor surface in a factory, and dust is easily collected near the floor surface, and air containing more dust exists. In such a state, when the first and second fans 8 and 8 ′ are operated, the first fan 8 below the upper side tends to suck air closer to the floor surface than the upper side. On the other hand, the lower first fan 8 has a smaller air volume and a smaller intake force than the upper second fan 8 '. Thereby, the amount of dust sucked in by the lower first fan 8 is suppressed, and intrusion of dust from the first fan 8 is effective even in the lower first air passage 9 close to the floor surface. It is suppressed.

図10に示す電源装置A1では、電気部品32がたとえば第2の風路9’の上部壁となる第1の仕切板6を貫通してコイル部分32Aが第2の風路9’内に位置するように配置されている。第2のファン8’からの風は、電気部品32のコイル部分32Aとヒートシンク5のフィン51に当たりながら第2の風路9’の長手方向両端部へと流れて外部に吹き出る。このような構成によれば、1つの風路9’の異なる壁に沿って配置された複数の部品を効率よく空気冷却することができる。なお、その他には、ファンが配置された垂直壁、あるいは上部壁に対向する底部壁に部品を配置しても、同様の効果を得ることができる。 In the power supply device A1 shown in FIG. 10, the electric component 32 penetrates the first partition plate 6 that becomes the upper wall of the second air passage 9 ′, for example, and the coil portion 32A is positioned in the second air passage 9 ′. Are arranged to be. The wind from the second fan 8 ′ flows to both ends in the longitudinal direction of the second air passage 9 ′ and blows outside while hitting the coil portion 32 A of the electrical component 32 and the fins 51 of the heat sink 5. According to such a configuration, a plurality of components arranged along different walls of one air passage 9 ′ can be efficiently air-cooled. In addition, the same effect can be obtained by arranging parts on the vertical wall on which the fan is arranged or on the bottom wall facing the top wall.

図11に示す電源装置A2では、筐体カバー2の側面部2Aにおける吸気孔部20は、その側面部2AのF方向両端部寄りの領域でかつ上下方向中間部付近に設けられている。この電源装置A2を工場内の床面上に配置した場合、吸気孔部20は、粉塵が集積した床面付近より上方に離れて位置する。そのため、配置空間B2には、吸気孔部20を通じて空気とともに吸い込まれる粉塵の量が抑えられ、ひいては第1および第2の風路9,9’に対する第1および第2のファン8,8’からの粉塵の侵入がより効果的に抑制される。このような粉塵の侵入を抑制する効果は、吸気孔部20を上下方向上部寄りに位置させるほどより高めることができる。 In the power supply device A2 shown in FIG. 11, the intake hole 20 in the side surface portion 2A of the housing cover 2 is provided in a region near both ends in the F direction of the side surface portion 2A and in the vicinity of the middle portion in the vertical direction. When this power supply device A2 is arranged on the floor surface in the factory, the intake hole 20 is positioned away from the vicinity of the floor surface where dust is accumulated. Therefore, the amount of dust sucked together with the air through the intake hole 20 is suppressed in the arrangement space B2, and as a result, from the first and second fans 8, 8 ′ with respect to the first and second air passages 9, 9 ′ . Intrusion of dust is more effectively suppressed. The effect of suppressing such dust intrusion can be further enhanced as the intake hole 20 is positioned closer to the upper part in the vertical direction.
