Abstract

It is a thin plus cooling fan structure that includes a case, a fixed stand, a fan wheel and a cover. The case sets a container that there sets an axle pipe at the bottom for combination of the fixed stand and fan wheel. The proper position in one side of the container sets an exit vent, and the cover sets an entrance vent which enables the top of the blade of the fan wheel to protrude outside the cover, and the bottom of the blade extends into under the cover to make the blade not to touch the cover when the blade rotates. When the fan wheel rotates, the air outside enters through the entrance vent of the cover, and takes heat inside away the case, and blows out through the exit vent of the case. The structure of the thin plus cooling fan can increase the area of the blade to raise the air volume and eliminate the noise of wind shear.
