Description

Three-dimensional radiating temperature-equalizing plate

Technical Field

The utility model relates to a temperature-uniforming plate.

Background

Along with the increasing power consumption of electronic elements on the market, the packaging is more and more miniaturized, in a narrow space, the contradiction between the performance of the electronic elements and the density of the generated heat flux is more and more serious, and the heat dissipation problem of the electronic elements is related to the reliability and the service life of equipment. At present, a heat transfer technology based on a two-dimensional plane is adopted in the market, namely a temperature equalizing plate.

The traditional vapor chamber utilizes the principle of capillary adsorption evaporation heat dissipation and adopts a circulating heat dissipation mode of heat absorption evaporation condensation in the Z direction. The working process comprises the following steps: the heat source is attached to the surface of the temperature-equalizing plate and transfers heat to the evaporation cavity. The liquid in the capillary core layer absorbs heat, evaporates along the Z direction and diffuses to two sides, condenses back to liquid after encountering the cold edge of the core layer, and returns liquid for circulation through capillary adsorption, thereby achieving the effect of circulating, evaporating, radiating and cooling.

Therefore, the traditional temperature-uniforming plate can not realize three-dimensional heat dissipation on the premise of being relatively thin, and the heat dissipation effect is poor.
