[0002] With the continuous development of modern military electronic technology, the heating power of electronic equipment is also increasing, but the volume is becoming smaller and smaller. Those small and compact multi-functional electronic control systems, electronic interference systems, etc. are extremely harmful to heat and pollution. Sensitive, overheating will cause these sensitive electronic and electrical components to fail, the digital display system will display incorrectly, the control system will drift and the system will malfunction when it is lower than the rated load. At present, some old military aircraft and electronic equipment in our country still use natural heat dissipation And air-cooled heat dissipation method, this heat dissipation method not only has low cooling efficiency, but also absorbs dust, oil and other impurities in the air on the surface of electronic components during the test on the ground, which will reduce the heat dissipation efficiency of electronic components. Traditional natural heat dissipation or air-cooled heat dissipation can no longer meet the heat dissipation requirements of these electronic equipment; some small-scale high-power mission electronic systems being developed by various electronic research institutes in China must carry out a large number of verification tests during the development process. These verification tests Some old models in our country are needed as flight test platforms. These old models, such as J7, Yun 8 and J8, are not equipped with environmental control liquid cooling systems. Although some aircraft are equipped with environmental control liquid cooling systems, they have not reserved special The liquid cooling interface is used for the test. Due to the limitation of the installation position of some electronic equipment on the machine, the environmental control liquid cooling system on the machine cannot be used.
