Abstract

PURPOSE: To lessen the generation of niose by forming a fan into such a shape that the fitting angle of the fan at any diameter can be represented by a specific formula in order to equalize the flow of air before and after the fan.
CONSTITUTION: The fan 2 is formed into such a shape that the fitting angle β of a fan at any diameter D of the fan can be represented by the formula β/βm= (D/Dm)-n (where 1.0≤n≤1.5, Dm is the effective diameter of the fan 2, and βm is the fitting angle of the fan at the position of effective diameter). Thus, the flow of air before and after the fan 2 can be equalized without reduction of air amount and the generation noise can be lessened without lowering the cooling efficiency of engine.
