Technical Field

[0001] The utility model relates to the technical field of motor fan covers, in particular to an aluminum alloy motor fan cover. Background Art

[0002] The motor fan cover, also known as the motor fan cover, is a protective device for the motor fan. It is mainly used to protect the motor fan from external objects and prevent these external objects from entering the interior of the motor fan, thereby ensuring the normal operation of the motor fan. In addition, the motor fan cover can also keep the interior of the motor fan clean and reduce the wear of the fan blades, thereby extending the service life of the fan.

[0003] At present, some motor fan covers are also made of aluminum alloy. Aluminum alloy motor fan covers are manufactured for installation and use. A plurality of heat dissipation holes are usually opened at one end of the aluminum alloy motor fan cover for heat dissipation. When the heat dissipation holes are blocked by dust, the heat dissipation will be affected. Generally, the aluminum alloy motor fan cover needs to be disassembled from the equipment as a whole, and then the dust on the heat dissipation holes is cleaned with tools. However, the aluminum alloy motor fan cover is generally fixed to the equipment by multiple screws, and it is troublesome to disassemble it. Therefore, this method of cleaning the dust in the heat dissipation holes by disassembling the aluminum alloy motor fan cover is relatively troublesome. Therefore, an aluminum alloy motor fan cover is now proposed. Utility Model Content
