Embodiment Construction

[0012] The present invention will be further described in detail below in conjunction with the drawings.

[0013] Such as figure 1 As shown, the present invention includes a housing 10 and an upper cover 2 connected to the housing 10. It is characterized in that the housing 10 is at least partially cylindrical, and the upper surface of the housing 10 is also provided with an extension extending in the height direction of the housing 10 The blind hole 16 has an aperture larger than the outer diameter of the fan. The upper cover 2 has a plate shape and is covered on the blind hole 16 on the upper surface of the housing 10 by a number of fasteners. The upper cover 2 is also provided with a first through hole 4 that penetrates vertically, and the diameter of the first through hole 4 is smaller than the outer diameter of the fan.

[0014] Place the fan in the blind hole 16 inside the casing 10, cover the upper cover 2 on the blind hole 16, and fix the two with fasteners, because the up...

Abstract

The invention discloses a CPU (central processing unit) fan housing comprising a housing body and an upper cover connected to the housing body. The CPU fan housing is characterized in that the housing is partially cylindrical at least, the upper surface of the housing is provided with a blind hole extending in the height direction of the housing, the diameter of the blind hole is larger than the outside diameter of a fan, the upper cover is plate-shaped and covers the blind hole in the upper surface of the housing through a plurality of fasteners, the upper cover is also provided with a vertically through first through hole, and the diameter of the first through hole is smaller than the outside diameter of the fan. The fan is disposed in the blind hole inside the housing; after being rested on the blind hole, the upper cover is fastened to the blind hole through the fasteners; the first through hole is provided above the upper cover, and the radiating effect of the upper cover is unaffected; the CPU fan housing can effectively prevent foreign matters from contacting with the edge of the fan, and the fan is protected from scratches impairing the durability.

Description

Technical field [0001] The invention relates to a cooling device, in particular to a cooling fan accessory used by a computer CPU. Background technique [0002] In recent years, as the conversion capacity of power circuits has continued to increase, power consumption has increased accordingly, and various electronic components have also generated a huge amount of heat, which has brought heat dissipation problems, and then has produced heat dissipation devices. As for CPU components, the increase in integration and operating frequency will increase the requirements for heat sinks. [0003] In the prior art, the fan is directly fixed inside a cylindrical shell without any protective cover or other protection facilities. When the fan rotates at a high speed, its edge may be damaged by foreign objects, which affects its durability. Summary of the invention [0004] The technical problem to be solved by the present invention is to provide a fan housing with improved durability. [0005] ...
