The CPU radiator is used to dissipate the heat for the CPU. The radiator plays a decisive role in the stable operation of the CPU. It is very important to choose a good radiator when assembling a computer.

[0004] The CPU radiator in the above patent can only achieve the purpose of easy installation when in use. However, when the existing CPU radiator is in use, due to the gaps in the cooling fins and the cooling fan absorbing air through the inside of the cooling fins when starting, a large amount of impurities in the air will remain inside the cooling fins, and the internal space of the cooling fins is relatively narrow, which is inconvenient to clean. Therefore, a device is needed to improve the above problem. Utility Model Content

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

The cooling fan 12 is fixedly installed at the front end of the cooling fins 13 and contacts the CPU 5 through the cooling fins 13, so that the CPU 5 can conduct heat to the inside of the cooling fins 13.

[0022] The positioning device 3 includes an L-shaped positioning rod 15, a supporting cavity 16, a base 17 and a positioning spring 18. The supporting cavity 16 is fixedly installed on the top ends of both sides of the base 17, the positioning spring 18 is fixedly installed on the inner bottom end of the supporting cavity 16, and the L-shaped positioning rod 15 is fixedly installed on the top end of the positioning spring 18.
