摘　　要：装在冷却风扇进口处的护罩会减少风扇的进风面积和设计风量（约降低四分之一左右）。考虑到护罩的影响，风扇设计的进风面积必须增大。The air cowling, which is installed at the inlet of the cooling fan, will reduce the inlet airarea and designed air quantity of the fan (about one quarter of air quantity is reduced). In considerationof the effect of the air cowling, the designed inlet air area of the fan must be increased.
