The traditional heat dissipation technology can not meet the increasing power heat dissipation requirement, at present, a temperature-equalizing plate is a relatively good heat dissipation technology, the temperature-equalizing plate is of a sheet structure and is inserted between a heat source and an external heat dissipation structure, the temperature-equalizing plate can take away heat quickly during work, heat can be prevented from being concentrated on the heat source, and the heat can be dissipated out timely.

The temperature equalizing plate is generally a vacuum cavity structure consisting of an upper shell, a middle capillary layer, a lower shell and an internal working medium. The working principle of the temperature equalizing plate is that when the heat absorption area of the temperature equalizing plate is contacted with a heat source, the liquid phase working fluid in the capillary structure of the heat absorption area absorbs heat energy and is converted from a liquid phase to a gas phase. Due to the pressure difference in the element, the gas phase working fluid flows rapidly from the air passage in the cavity to the far-end condensation area. Latent heat is released when the vapor phase working fluid flows to a condensation zone remote from the heat source, transitioning from the vapor phase working fluid to the liquid phase working fluid into the capillary structure. Then, the liquid phase working fluid is transported and reflowed to the heat absorption area by the capillary force of the continuous capillary structure in the cavity, and the liquid phase and the gas phase flow circulation is formed. The temperature equalizing plate element achieves the purposes of quickly conducting heat energy, reducing temperature and dissipating heat through the phase change and circulation of the working fluid.

The existing temperature equalizing plate is mostly provided with point-shaped bulges on the surface of a single-side cover plate, has a single capillary structure, and is difficult to promote because the heat dissipation capacity of the existing temperature equalizing plate is limited to a certain extent.
