Locked on the heat sink 10, and the bottom of the heat sink 10 is provided with a connecting bracket 30 and a fastening strip 301, and the cooling fan 20 fixed on the heat sink 10 is fixed to the heating chip by the fastening strip 301 (Fig. (not shown in the figure), so as to transfer the heat generated by the heating chip to the external environment in time, so as to maintain its normal operation.

However, there are following disadvantages in the existing above-mentioned cooling fan fastener:

1. The product structure of the above cooling fan buckle is relatively complicated, there are too many combined parts, and there are relatively many assembly processes, which wastes man-hours;

2. The fan support frame of the above cooling fan buckle is mostly plastic parts, which are easily deformed and cause poor appearance;

3. After the fan support frame of the heat dissipation fan fastener is disassembled, it cannot be reused, and the cost of scrapping is high.

In view of this, it is necessary to provide a cooling fan fastener with simple structure and convenient assembly.

【Content of invention】

Therefore, the object of the present invention is to provide a heat dissipation fan fastener, which has a simple structure and is easy to assemble.

In order to achieve the above object, the present invention provides a heat dissipation fan fastener for fixing a heat dissipation fan on a heat dissipation device.
