Problems solved by technology

However, this fixing device is prone to deformation of the snap ring and falls off or the clasp scratches the coating on the outside of the rod, causing the rod to rust, forming a hidden danger.
In addition, during the installation process, the small snap ring must be snapped onto the slot of the rod, which is cumbersome to operate

Embodiment Construction

[0015] Please refer to FIG. 1 , a fixing member according to a preferred embodiment of the present invention includes several fixing members 10 . Taking the fixing of the heat sink 20 on the circuit board (not shown) as an example, the fixing device of the preferred embodiment of the present invention will be described in detail below.

[0016] The heat sink 20 includes a base 21 that is attached to the electronic components on the circuit board to absorb heat, a number of heat sinks 26 that are fastened together, three heat pipes 24 that are thermally connected together with the heat sink 26 and the base 21, and a power supply. The fixing member 10 passes through to fix the heat sink 20 to two fixing feet 22 on the circuit board.

[0017] The base 21 has a body 210, which is provided with a straight groove 212 corresponding to the heat pipe 24, and a flange extends horizontally outward from the upper half of the side edges of the body 210 parallel to the groove 212. 214 , th...

Abstract

This invention relates to a fixing piece for fixing a radiator on a CB including several fixing pieces, every one of which includes a sleeve, a screw and an elastic element changing the shape along the radial direction of the sleeve, in which, one end of the sleeve forms a head, the other end is set with an elastic piece changing shape along the radial direction and having an agnail structure, said elastic element is set outside of the sleeve and placed between the head and the agnail structure, one end of said screw is fixed in the sleeve,the other end includes a screw section popping out of the sleeve, which can either cover the spring on the fixing piece or assemble the fixing piece to the radiator in advance conveniently.

Description

technical field [0001] The invention relates to a fixing part, its manufacturing method and a heat dissipation device combination using the fixing part. Background technique [0002] With the rapid development of the computer industry, the operating capabilities of electronic components such as central processing units continue to improve, and their heat generation is also increasing. Heat dissipation has become a problem that must be solved when these heat-generating electronic components are used. At present, the solution commonly adopted in the industry is to install a heat sink on the electronic components to dissipate heat. The radiator needs to be fixed on the electronic components with a fixing device. The effect of this fixing device will directly affect the heat sink and electronic components. The heat exchange efficiency between components affects the heat dissipation effect. [0003] The fixing device disclosed in US Patent No. 5,901,039 is a screw-fit fixing dev...
