Composite heat dissipation system

Abstract

The invention relates to the heat dissipation field and provides a composite heat dissipation system. The composite heat dissipation system includes a phase change structure and a vacuum chamber soaking plate which abut each other, wherein the phase change structure includes a rib, liquid metal alloy and an outer chamber, multiple ribs are disposed in the outer chamber at intervals, and the liquid metal alloy is loaded in a hollow structure formed by the outer chamber and the ribs. The composite heat dissipation system is advantaged in that heat transferred to the vacuum chamber soaking plate in one direction is transferred to other directions of the vacuum chamber soaking plate through the liquid metal alloy, the heat is absorbed and liquefied by utilizing the solid metal alloy in the outer chamber, heat dissipation efficiency of the vacuum chamber soaking plate is effectively enhanced, moreover, the waste heat of the vacuum chamber soaking plate is reduced, and heat dissipation of the vacuum chamber soaking plate and energy storage of the phase change material are realized.

Description

technical field [0001] The invention relates to the field of heat dissipation, in particular to a composite heat dissipation system. Background technique [0002] With the social industry and people's pursuit of high-power devices and small integration. What follows is the problem of heat dissipation of high-power devices, for example, heat dissipation of game consoles, heat dissipation of lasers, etc. How to deal with the heat in the equipment in time without causing damage to the equipment and products has become a research hotspot. [0003] At present, the application of the vacuum chamber vapor chamber dissipates the heat of the heat source to the surrounding environment with a large heat transfer coefficient, but the heat of the vacuum chamber vapor chamber itself can only be dissipated to the surrounding environment with a small heat dissipation coefficient. Vacuum chamber vapor chamber heat dissipation generally adopts natural air convection, fan forced convection o...

AI Technical Summary

Problems solved by technology

The efficiency of air convection cooling is not high, and the operation process of liquid flow cooling is cumbersome, which is easy to cause damage to the equipment

The heat emitted by the vapor chamber in the vacuum chamber is finally absorbed by the environment as waste heat, which causes energy waste and accelerates the greenhouse effect.
