【Background technique】

With the rapid development of the computer industry, the operating speed of electronic components is getting faster and faster. The introduction of high-frequency and high-speed processors has become an inevitable trend. However, high-frequency and high-speed operation causes the heat generated by electronic components to increase rapidly. As a result, the temperature of the electronic components continues to rise, and the stability of its operation is greatly affected. In order to dissipate the heat generated in time and quickly, it is necessary to install a radiator on the electronic components. At the same time, in order to ensure the heat dissipation of the radiator High efficiency, in addition, it is necessary to install a fan on the radiator to assist in heat dissipation.

In the prior art, most of the cooling fin structures of the radiator are aluminum extruded or folded, and their shapes are also different. Generally, screws are used to directly lock the fan on the cooling fins of the radiator from the top. However, this The fixing method is not only insufficient in bonding force, but also easily deforms the cooling fins and causes slippage, which separates the fan from the radiator; there are also fan fixing brackets that fix the fan to the radiator. However, the overall fan fixing frame needs to be designed according to the shape of the radiator, which is difficult to process, consumes more materials, and has high manufacturing costs. The frame surrounds the fins of the radiator and affects the cooling effect. In order to overcome the problems caused by the fixing method of the overall structure of the fan fixing frame in the heat dissipation device and various difficulties encountered in manufacturing, it is necessary to design a new type of fan fixing frame and change the many disadvantages caused by the traditional fixing frame.
