The hardware system in the existing electronic equipment is generally provided with the heat dissipation device for independently controlling the central processor and the graphic processor, and the reason is that the degree of cooling required by the central processor and the graphic processor is greatly different in the running process of the system, and the heat dissipation device which is independently arranged can adjust the respective cooling intensities according to the temperature rising amplitude of the central processor and the graphic processor, so that the central processor and the graphic processor can be more accurately cooled to the proper temperature, the controllability of the heat dissipation function in the hardware system is effectively improved, and the running quality upper limit of the electronic equipment system is also conveniently tested.

The heat sink in the existing electronic device has a part of defects, because the independent heat sink can only cool down the central processing unit or the graphics processor, but when the hardware system operates, the load operation central processing unit, the normal operation or the low power operation graphics processor exist, and the load operation graphics processor, the normal operation or the low power operation central processing unit are in condition, so that the heat sink responsible for controlling the temperature of the normal operation or the low power operation part does not cool down in high power operation, and the heat sink responsible for controlling the temperature of the load operation part is easy to reach the upper cooling limit, thereby being forced to reduce the operation rate of the system.
