Abstract
PURPOSE: To effectively utilize a blade area and prevent a pressure loss of a fan by controlling the cooling air flow at the inport of the fan.
CONSTITUTION: A fan 4 and a guide-ring 5 having a projection 8 are equipped in a housing 1. In this case, D1<Df is set (wherein D1 is a diameter of a guide-ring in the fan side, Df is an outer diameter of the fan. Then, the cooling air flows to the central direction of the fan 4. Thus, a cooling efficiency is improved by effectively utilizing the total blade area of the fan.
