車２の入口側７と出口側８に連通している。[Example] Fig. 1 is a front view of an embodiment, and Fig. 2 is a partial sectional view of Fig. 1, in which a casing 13 surrounding a centrifugal impeller 2 fixed to the shaft end 1 of a rotating shaft is covered. 4, and the casing 1
Cooling air inlet 15 and outlet 16 are located apart in the axial direction of 3.
and communicates this population 15 and outlet 16 with the inlet side 7 and outlet side 8 of the impeller 2, respectively.
ここまでは従来例とおよそ同一構造であるが、実施例の
特徴的な構造として、前記入口１５と出口１６とを周方
向に離し、この人口１５と出口１６との間に、前記ケー
シング１３の外周の軸方向に堰１０を設ける。Up to this point, the structure is approximately the same as that of the conventional example, but as a characteristic structure of the embodiment, the inlet 15 and the outlet 16 are separated in the circumferential direction, and the casing 13 is placed between the inlet 15 and the outlet 16. A weir 10 is provided in the axial direction of the outer circumference.
なお、羽根車は遠心形と限らず、斜流形、軸流形等も採
用でき、軸流形で外径がケーシング１３に接近していれ
ば、円板９を必要としない。Note that the impeller is not limited to the centrifugal type, but may also be of the mixed flow type, axial flow type, etc. If the impeller is of the axial flow type and the outer diameter is close to the casing 13, the disk 9 is not required.
このような構造によれば冷却風の入口と出口とはケーシ
ング上で周方向に離れているうえに堰が間にあるので、
出口を出た空気が入口に再び入るような循環が大幅に減
少し、冷却効果が向上する。According to this structure, the inlet and outlet of the cooling air are separated from each other in the circumferential direction on the casing, and there is a weir between them.
Circulation of air leaving the outlet and re-entering the inlet is significantly reduced, improving the cooling effect.
