Abstract

An advanced ventilator vane structure comprises multiple vanes set equidistantly on the same surface of the center of a base. The tortuosity of each vane is like S-type shape and its free end is an arc fringe. This special shape of the vanes could reduce the wind resistance and the turbulence, as well as the noise caused by resonance. This invention achieves the purpose of improving the economic efficiency via enhancing wind-force by increasing the rotary power and the speed of the vane.
