Abstract
PURPOSE: To reduce noise of a motor fan provided with a motor and moving vane by setting, a radius of curvature of the tip part on the trailing edge side of the moving vane and a chord length on the outer diameter, thereof at a specified value.
CONSTITUTION: A motor fan comprises a motor 3, a moving vane 2 driven by the motor 3 and a casing 1 enveloping the moving vane 2. A radius of curvature of the tip part on the trailing edge side of the moving vane 2 is set at about 0.1D0 or about 0.2l, wherein D0 and l represent the outer diameter of the fan and the chord length on the outer diameter of the moving vane respectively. Thus, the flow over the vane surface at the tip part thereof is made to be smooth and the leakage of vortex at the tip part is suppressed so that it is possible to reduce the generation of noise.
