Problems solved by technology

However, the heat generated by electrical components cannot be accumulated in the electrical components and must be dissipated effectively, otherwise the performance and working life of the electrical components will be reduced, and the electrical components may even be damaged
[0003] Traditional heat dissipation methods such as air cooling, air cooling, and water cooling can no longer meet the needs of the development of electrical technology due to factors such as low heat dissipation efficiency, safety, and corrosion and damage to electrical components.

Abstract

The invention discloses a phase change cooling system, which comprises an evaporation part, a condensation part and an evaporation and condensation pipeline, and is characterized in that the evaporation and condensation pipeline connects the evaporation part and the condensation part into a run-through circulation loop; the circulation loop is filled with a liquid-state working medium; the evaporation part is composed of a plurality of internally communicated heat absorbing plates which are arranged in an array mode, the top parts of the plurality of heat absorbing plates are connected with aninlet of the condensation part, and the bottom parts of the plurality of heat absorbing plates are connected with an outlet of the condensation part. The phase change cooling system utilizes phase change heat transfer to replace water cooling, and improves the heat transfer efficiency. In addition, a cooling plate serving as the evaporation part has a characteristic of heat equalization, and thetemperature difference of points on the cooling plate can be controlled within 3 DEG C.

Description

technical field [0001] The invention relates to a cooling system, in particular to a phase change cooling system. Background technique [0002] With the continuous development of electrical technology, electrical components are developing in the direction of smaller volume, higher integration, faster work and higher power density. All this means that when the electrical components are working, a greater heat flux is generated. However, the heat generated by electrical components cannot be allowed to accumulate in the electrical components, and must be dissipated effectively, otherwise the performance and working life of the electrical components will be reduced, and the electrical components may even be damaged. [0003] Traditional heat dissipation methods such as air cooling, air cooling, and water cooling can no longer meet the needs of the development of electrical technology due to factors such as low heat dissipation efficiency, safety, and corrosion and damage to e...
