However, in the application process, a part of the cooling liquid can circularly flow at the cold end of the liquid absorption core and cannot rapidly and timely flow back to the hot end, so that the cooling liquid at the hot end is reduced, and the heat carried by the cooling liquid after heated and vaporized can not be timely discharged from the cold end, so that the circulating efficiency and the heat transfer effect of the cooling liquid in the soaking plate are reduced, the heat dissipation effect of a chip is reduced, even the condition that the soaking plate is aged due to dry burning is generated, and the service life of the soaking plate is shortened.

In addition, the microstructure of the vapor chamber is usually formed by stacking a plurality of layers of copper meshes, however, the permeability of the microstructure formed by the plurality of layers of copper meshes is not high, so that when the vapor chamber is used in a high-power environment, the phenomenon that the cooling medium at the cold end flows back and is interrupted to the hot end to cause the dry burning at the hot end occurs, and the heat dissipation efficiency of the vapor chamber is influenced.
