The wind causes airflow by the fan 6 and is taken in from the suction port 5, and the flow is indicated by the arrow 3. In the air-cooling case according to the first embodiment, the gap generated at the joint 4 can be minimized.

次に、図２、図３を参照して、上部筐体１および下部筐体２の各部の詳細について説明する。ここで、図２は、図１のＡ−Ａ断面の分解図である。図３は穴７部付近の拡大図である。   Next, with reference to FIGS. 2 and 3, details of each part of the upper housing 1 and the lower housing 2 will be described. Here, FIG. 2 is an exploded view of the AA cross section of FIG. FIG. 3 is an enlarged view near the hole 7.

上部筐体１には、段差部１１の場所に設けた穴部７と上側ラップ部８が設けられている。ここで、実施例１では、上部ラップ部８について、段差部１１を備えた上部筐体１との一体構造としているが、別部品としても良い。下部筐体２には爪部９と下側ラップ部１０が設けられている。   The upper housing 1 is provided with a hole 7 provided at the location of the step 11 and an upper wrap 8. Here, in the first embodiment, the upper wrap portion 8 has an integral structure with the upper housing 1 having the step portion 11, but may be a separate component. The lower housing 2 is provided with a claw 9 and a lower wrap 10.

このように、実施例１の空冷用筐体は、対向する一対の側面部と上面部とを有する断面がコの字型に形成された上部筐体１と、板状の下部筐体２とを有する。上部筐体１の側面部には、穴部７と上側ラップ部８が設けられている。下部筐体２には、爪部９と下側ラップ部１０が設けられている。   As described above, the air-cooling housing according to the first embodiment includes the upper housing 1 having a pair of opposed side surfaces and the upper surface and having a U-shaped cross section, and the plate-shaped lower housing 2.
