Claims

1. A cooling fan cover, comprising a cooling cover body, the cooling cover body having an inner surface and an outer surface, wherein the outer surface of the cooling cover body has a plurality of holes arranged therein, the plurality of holes being able to penetrate the cooling cover body and be transparent to the inner surface of the cooling cover body, and the radius of the holes on the outer surface of the cooling cover body gradually increases from the radius of the holes on the inner surface of the cooling cover body.

2. The cooling fan cover as requested in item 1, wherein the plurality of holes are arranged in a ring or spiral shape.

3. The cooling fan cover as requested in claim 2, wherein the distribution is arranged in a ring close to the outer surface of the cooling cover.

4. As in claim 3, the cooling fan cover is further connected to an air collecting cover on the inner surface of the cooling cover. The air collecting cover includes an inner surface of the air collecting cover and an outer surface of the air collecting cover. The outer surface of the air collecting cover has a plurality of spirally distributed arc-shaped grooves. The plurality of arc-shaped grooves penetrate the air collecting cover and are permeable to the inner surface of the air collecting cover to concentrate the air force from the fan blades and transmit it to the perforations on the inner surface of the cooling cover.

5. The cooling fan cover as claimed in claim 1, wherein an outer cover is further connected to the outer surface of the cooling fan cover.

6. The cooling fan cover of claim 1 further comprises a plurality of hollow cones that protrude from the outer surface of the cooling fan cover through holes in the inner surface of the cooling fan cover.

7. The cooling fan cover as requested in item 3, wherein the inner side of the cooling cover is connected to the fan by a snap-fit ​​ring.

8. The cooling fan cover as requested in item 1, wherein the outer layer of the cooling cover is connected to a mesh with a plurality of openings.
