[0002] The heat spreader is a vacuum cavity with a microstructured inner wall, usually made of copper. When heat is transferred from the heat source to the evaporation zone, the coolant in the cavity begins to vaporize after being heated in a low vacuum environment. At this time, it absorbs heat energy and expands rapidly in volume. The gas phase cooling medium quickly fills the entire cavity. When the gas phase working medium contacts a relatively cold area, condensation will occur, and the heat accumulated during evaporation will be released through the condensation phenomenon. The condensed coolant will return to the evaporation heat source through the microstructured capillary channel. This operation will be repeated in the cavity.
