Description

water cooling device

In order to meet the needs of users, the working clock of the chip on the interface card is as high as hundreds of millions of hertz (Hz). ), and with such a high frequency of work, heat problems should arise. When the temperature of the interface card is too high, the power consumption will increase in the lightest case, and the life of the processor may be shortened in the severe case, which will seriously affect the efficiency, reliability and stability of the processor. Therefore, in order to remove the heat of the interface card, there is known a water-cooled heat dissipation system composed of a pump, a water-cooling head, and a radiator. The general working method is that the heat exchange element exchanges heat with the heat source of the interface card, and then cools the liquid by cooling the liquid.

The cooling liquid is pressurized by the pump and flows into the radiator, so as to achieve the effect of rapid heat dissipation, so that the interface card can operate normally. However, the conventional water cooling system only sets the water cooling head on the main heating element (such as a graphics processor) to dissipate heat from the main heating element, but other heating elements are also arranged around the main heating element. The heat dissipation system cannot dissipate heat from other heating elements, resulting in poor heat dissipation of the interface card. Therefore, how to solve the above-mentioned problems is the direction that those skilled in the art should strive for.
