ABSTRACT:
A cooling fan includes a hub (40) and blades (50) extending radially from the hub. Each of the blades is divided into strip zones (505, 51, 52, 53, 54, 55, 56), projections of homocentric arcs concentric with the hub on the blades are defined as boundaries of the zones. The zones are coated with a layer of paint with different colors to present a rainbow-liked image when the fan is in operation.
