Compared with the fan, the heat dissipation fins in the heat dissipation fin group are arranged laterally.

The periphery of the fan is provided with a windshield.

The bottom end of the base is fixedly connected with a backplane bracket.

A buffer pad is provided between the backplane support and the base.

A fixing seat is arranged under the fan, and the fan is fixed on the fixing seat, and a fixing hole is arranged on the fixing seat.

The base is provided with screw holes for fixing the fixing seat under the fan.

The beneficial effects of the utility model are:

The utility model provides a computer heat dissipation device, which comprises a fan, a base made of graphite composite material and a cooling fin group, the cooling fin group is located at the top of the base, and the base and the cooling fin group It is integrally formed, wherein the base and the heat dissipation fin group jointly constitute the accommodation area for placing the fan, and the fan is placed in the accommodation area; since the price of graphite composite material is much lower than that of copper and aluminum, the utility model has the advantages of low cost. low, and the base made of graphite composite material is light in weight, fast in heat conduction, and high in heat dissipation efficiency. features. Further, compared with the fan, the heat dissipation fins in the heat dissipation fin group are arranged laterally, so that the fan located at one end of the heat dissipation fin group can quickly blow away the heat accumulated on the heat dissipation fins.
