Abstract

A cooling fans is applied in a server, and includes a rotary shaft and several blades. The rotary shaft is composed of a main shaft and an extension shaft. The diameter of the main shaft is greater than the diameter of the extension shaft. The blades are formed from the rotary shaft and blows wind from one side to another side. Due to smaller diameter of the extension shaft, the area of the blades which can cut air would increase. Thus, the cooling fans improves the efficiency of dispersing heat.
