Description

Technical Field

[0001] This utility model relates to the field of liquid cooling system technology, specifically to a composite pressurized liquid storage container for a liquid cooling system. Background Technology

[0002] The liquid cooling system consists of a tail liquid cooling unit and a ground liquid cooling unit. The tail liquid cooling unit is installed at the tail of the special aircraft and provides the required liquid flow and temperature for heat dissipation of the tail antenna within the characteristic temperature range. The ground liquid cooling unit provides the tail antenna with the required liquid cooling capacity during ground connection testing. However, the cooling system requires the use of pressurized liquid storage containers. The existing pressurized liquid storage containers have a single pressurization method, which relies on a pressurization pump. The pressurization effect is poor, a large-sized pressurization pump is required, which consumes a lot of electrical energy and occupies a lot of space. In addition, the pressurization level of the existing pressurization device cannot be adjusted, which is inconvenient to use. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a composite pressurized liquid storage container for a liquid cooling system. It has a simple structure and is easy to operate. It can not only be pressurized by a booster pump, but also further pressurized by elastic extrusion. The self-pressurization magnitude can be adjusted to make the pressurization effect better and effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a composite pressurized liquid storage container for a liquid cooling system, comprising a pressurized tank body, a left end cap sealed to the left end of the pressurized tank body, a right end cap connected to the right end of the pressurized tank body, a piston cylinder connected to the center of one side of the right end cap via a threaded connection, a sliding piston one disposed inside the piston cylinder, a connecting rod fixed to the center of one side of the piston one, one end of the connecting rod passing through the right end cap and located inside the pressurized tank body, a piston two fixed to the end of the connecting rod located inside the pressurized tank body, the outer side of the piston two being connected to the piston cylinder... The piston is connected to the inner side by a sliding connection. A spring is connected to one side of the piston. An elastic adjustment element for adjusting the spring force is provided on the right end cover.

The elastic adjustment element includes two hydraulic telescopic columns fixed to one side of the right end cover. A support ring is fixed to the telescopic end of the hydraulic telescopic column. One side of the support ring is in contact with the spring.

[0005] Furthermore, two sealing rings are provided at the connection between the right end cover and the connecting rod, and an annular groove corresponding to the sealing rings is provided on the right end cover. The sealing rings can prevent the liquid inside the pressurized tank from escaping from the gap between the right end cover and the connecting rod.

[0006] Furthermore, both the lower end of the pressurization tank and the right end cover are provided with two mounting feet, each with mounting holes, allowing the device to be fixedly installed.

[0007] Furthermore, both piston one and piston two are provided with two annular grooves on their outer sides, and each annular groove is provided with a rubber ring inside, so that piston one and piston two are connected more tightly through the rubber ring.
