Abstract

The invention relates to the technical field of radiators, and discloses a small-sized compression refrigerating system based on a micro-channel heat exchanger. The small-sized compression refrigerating system particularly includes a compression refrigerating circulating system, the micro-channel heat exchanger and electronic heating elements to be cooled, wherein the electronic heating elements to be cooled are mounted on a runner of the micro-channel heat exchanger, the compression refrigerating circulating system is connected with the micro-channel heat exchanger through a connection pipeline, and a sealed closed pipeline loop is formed through connection pipelines and is filled with refrigerating fluid. The effect of cooling the electronic heating elements is achieved by integrating the small-sized compression refrigerating system and electronic equipment. Besides, the small-sized compression refrigerating system has the function of detecting and regulating the temperature in real time.

Description

technical field [0001] The invention relates to heat dissipation technology for electronic equipment, in particular to a system-level electronic equipment cooling device based on a microchannel heat exchanger and a compression refrigeration cycle, which can cool heating components and high heat flux heating components of electronic equipment. Background technique [0002] Conventional heat dissipation methods for electronic equipment mainly include forced air cooling, liquid forced cooling, micro-channel cooling, and semiconductor refrigeration. Among them, the principles of air forced cooling and liquid forced cooling are basically the same. Both use power components such as fans or liquid pumps to drive the flow of cooling air or cooling liquid, and take away the heat transferred from the electronic components to the heat exchanger through convective heat exchange in the heat exchanger. The heat of the heat exchanger. Microchannel cooling is also based on liquid forced co...
