Portable temperature-equalizing type spraying cooling circulating system for high-power electronic component

Abstract

The invention discloses a portable temperature-equalizing type spraying cooling circulating system for a high-power electronic component. The circulating system comprises a compressor, a spraying cooler and an air condenser, wherein an outlet of the compressor is connected with an inlet of the air condenser through a connecting pipeline; the outlet of the air condenser is connected with the inlet of the spraying cooler through the connecting pipeline; the circulating system is characterized by being provided with a gas-liquid separator and an auxiliary heating device; the outlet of the spraying cooler is connected with the inlet of the gas-liquid separator through a fluid conveying pipeline; the auxiliary heating device is arranged on the fluid conveying pipeline; the outlet of the gas-liquid separator is connected with the inlet of the compressor through the connecting pipeline; and a to-be-cooled piece is fixedly arranged on the spraying cooler. The auxiliary heating device and the gas-liquid separator are utilized in the circulating system provided by the invention to solve the problems that liquid phase exists before a refrigerant enters into the compressor and residual liquid after being subjected to spraying cooling cannot directly enter into the compressor for recompressing, so that spraying cooling closed circulation is realized and energy source is saved.

Description

technical field [0001] The invention relates to spray cooling, in particular to a portable uniform temperature spray cooling circulation system for high-power electronic components. Background technique [0002] With the rapid development of electronic technology, the requirements for the integration of electronic components and the stability of operation in fields such as computers, communications, aerospace, and military affairs are also constantly increasing. This makes the heat flux generated by the electronic components continuously increase, and the waste heat increases, resulting in an increasingly harsh thermal environment in which the electronic components operate. Working at temperatures above the rated temperature is the main cause of electronic components not functioning properly and reducing their lifespan. Relevant studies have shown that for every 5°C increase in the temperature of a semiconductor element, its working stability is reduced by about 20%. There...
