Abstract

The invention belongs to a liquid cooling technology of airborne electronic equipment and relates to an improvement of a supercharged expansion device of an aircraft liquid cooling system. The invention is characterized in that a supercharged expansion mechanism is composed of a supercharging case, a non-return valve (8), a pressure regulator (6), a safety valve (7) and a hollow rubber ball (9). According to the improved balloon piston-type supercharged expansion device of the aircraft liquid cooling system, automatic supercharging can be carried out by the system itself, and there is no need to install the device at the highest point of the liquid cooling system. Thus, height difference of installation space is minimized greatly, and use requirements of the device used on an aircraft without enough installation height difference are satisfied.

Description

technical field [0001] The invention belongs to the liquid cooling technology of airborne electronic equipment, and relates to the improvement of a pressurized expansion device of an aircraft liquid cooling system. Background technique [0002] Aircraft liquid cooling system is a closed cycle system, the current pressurized expansion device of an aircraft liquid cooling system can be found in figure 1 , which consists of a surge tank 1, a liquid cooling pump 2 and a pressurized expansion tank 3. The pressurized expansion tank 3 is provided with a safety valve 3a, a liquid filling port 3b and a liquid outlet of the expansion tank; the liquid inlet 1a of the surge tank 1 communicates with the liquid outlet of the radiator through a pipeline, and the outlet of the surge tank 1 The liquid port 1c communicates with the liquid inlet of the liquid cooling pump 2 through the pipeline, the liquid outlet of the liquid cooling pump 2 communicates with the liquid inlet of the cold plat...
