Title: Structure of a radiating fan

Abstract: An improved structure of a radiating fan comprises a blade seat, an axle center and a bearing. The central portion of the blade seat is installed with the axle center made of precision ceramic material, the outer peripheral surface of the axle center is covered by a hollow bearing made of precision ceramic material. Since the axle center and the bearing made of precision ceramic material have the advantages of long lifetime, low noise, and without using lubricating oil. Thus it is better than the axle center made of stainless steel and the oil bearing made of copper.
