Problems solved by technology

[0002] In the electronic pod environmental control system or aircraft liquid cooling system, when the flight altitude changes, the atmospheric pressure changes accordingly, and the elastic element of the self-pressurized liquid storage tank of the system will experience displacement when the atmospheric pressure changes, and the self-pressurized liquid storage tank The boost pressure of the tank will also change, which will cause the pump inlet pressure to fluctuate. When the pressure is less than a certain value, the pump inlet will generate negative pressure, which will cause cavitation damage to the pump impeller.

Abstract

The invention belongs to the field of electronic pod environmental control system or aircraft liquid cooling system, and in particular relates to a self-pressurized liquid storage tank of the electronic pod environmental control system, which includes a shell, an elastic element assembly, and a pump. One side of the shell is provided with a The system liquid return port and the pump connection port, the elastic element assembly is arranged in the housing, one end of the elastic element assembly is fixedly connected to the side wall inside the housing away from the system liquid return port and the pump connection port, and the other end is suspended in the housing. And it is close to the liquid return port of the system and the pump connection port. The pump is connected to the pump connection port of the casing. The invention can make the elastic element not be affected by the flight height and stabilize the boost pressure, so as to ensure the stability of the pump inlet pressure and prevent the pump The impeller produces cavitation, improving system reliability.
