An integrated liquid supply device for bellows type liquid introduction and pressurization of liquid cooling system

Abstract

The invention belongs to the technical field of aircraft or electronic pod liquid cooling system, and relates to a bellows-type liquid guiding pressurizing integrated liquid supply device of a liquidcooling system. The device is changed from original bellows or spring element pressurization to pressurization using a high-pressure liquid by leading the high-pressure liquid from a liquid cooling pump outlet to between the bellows and a housing or into the bellows. Pressure of the high-pressure liquid is stable, and action area is small. Action area of a low-pressure liquid is large, so as to achieve pressure balance. The device solves problems of easy leakage of motive seal, and wearing and life of a sealing ring. The device has no friction and wearing parts, and has stable performance, good repeatability and long life. The device changes volume measurement from conversion of pressure signals to direct measurement of bellows position signals, and can accurately measure volume changes ofa reservoir, and an output signal is more stable, accurate and reliable.

Description

technical field [0001] The invention belongs to the technical field of aircraft or electronic pod liquid cooling systems, and relates to an integrated liquid supply device for liquid cooling system bellows type liquid introduction and pressurization. Background technique [0002] The structure diagram of the liquid storage tank of the original liquid supply device is as follows figure 1 As shown, the bellows 13, the spring 14, the rear end cover 15, the front end cover 16 cooperate with the liquid storage tank shell 1 to form a self-pressurized liquid storage expansion tank. As the temperature of the liquid in the system increases, the liquid volume expands , the pressure rises; the bellows 13 and the spring 14 are continuously compressed under the action of pressure; the greater the volume expansion, the greater the elastic value of the bellows 13 and the spring 14, and the increase in the boost pressure, resulting in excessive pressure in the liquid cooling system.
