Heat Pipe CPU Cooler For Intel Alder Lake Socket LGA 1700 CPU

Heat pipe

Heat pipe is a classical two phase cooling device, which is one of the most efficient thermal components, the heat pipe is composed of copper tube, working fluid, wick structure. Generally the tube is sealed and vaccumed to form a vacuum-tight containment, in the inner wall, there is a wick structure to offer capillary force, also a small amount of working fluid is injected into the tube. When the envaporator end conduct the CPU, the working fluid vaporizes and absorbs the heat, the hot vapor flows to the other end by the air pressure, the hot vapor condenses at the condenser end and release the heat, the vapor turns into the liquid and return to the envaporator end with the capillary force of the wick structure, and then circulate the heat transporting process. This CPU cooler utilizes 4 heat pipes which is designed for high heat flux CPU, the 4 heat pipes construction design can remove the heat quickly and transport to aluminum fin stack rapidly, it is an excellent thermal solution.

Heat pipe direct conduction design

This heat pipe CPU cooler uses heat pipe direct conduction design to improve the thermal performance and save the cost. The heat pipes are inserted into an aluminum substrate, and goes through the rolling pressing process to ensure the flatness of the heat pipe surface, the flatness can reach 0.1mm. then put the thermal grease on the surface and contact with CPU directly. This design is briliant as the heat pipes conduct the CPU directly, which can significantly reduce the thermal resistance, the heat can be conducted to the heat pipes, and transported to the aluminum fin stack, the heat conduction efficiency is greatly improved, and don't need a copper pedestal to conduct the heat, so the design is also cost-effective.
