[0002] As we all know, the heat dissipation of high-heat generating components such as CPU / GPU / chips is mainly achieved through conduction, which involves the medium in direct contact with the processor - the heat sink. After the heat sink absorbs the heat, it dissipates the heat in the form of convection. In the process of convection heat dissipation, the heat dissipation area is mainly determined by the surface area of the heat sink fins. The larger the surface area, the better the heat dissipation effect; the smaller the surface area, the worse the heat dissipation effect. In order to improve the heat dissipation effect, the industry adopts water cooling, which uses the heat exchange medium to flow in the fins to take away the heat, thereby achieving rapid cooling.
[0003] The existing water-cooled heat dissipation cold plate includes a shell, fins and a cover; a water inlet and a water outlet are arranged on the cover, and fins are arranged in the shell, and the heat exchange medium enters through the water inlet, then flows through the fins and finally flows out through the water outlet, thereby realizing heat exchange and heat dissipation in a cycle.
