Technical field:

The utility model relates to the technical field of heat dissipation devices, in particular to a computer heat dissipation device.

Background technique:

As we all know, the chipset or processor of a computer will generate high heat during operation, and the operation speed is fast. The higher the driving power, the higher the temperature generated. If the temperature of the chipset or processor is too high, it will affect Therefore, if the heat dissipation problem cannot be solved, it will limit the operating speed of the chipset or processor, resulting in unstable operation of the computer.

Existing computer cooling devices are mainly composed of bases made of copper or aluminum alloys, heat dissipation fins, and fans for assisting heat dissipation. Due to the shortage of resources, the prices of copper and aluminum are gradually increasing. The computer cooling device made of aluminum has a relatively high cost. Moreover, because the density of copper and aluminum is relatively high, the computer cooling device made is heavy, easily crushes the chip, and is inconvenient to install.
