Adaptive pressure relief and liquid filling device of penetrating liquid cooling case of electronic equipment

Abstract

The invention discloses an adaptive pressure relief and liquid filling device of a penetrating liquid cooling case of electronic equipment. The adaptive pressure relief and liquid filling device comprises a cylinder block, and one end of the cylinder block is a connecting open end; a piston is arranged in the cylinder block, and extends out of the other end of the cylinder block; a liquid containing cavity is formed in the piston, and the side edge, located at the connecting open end of the cylinder block, of the liquid containing cavity communicates with the cylinder block; and the liquid containing cavity communicates with outside or is closed through a differential pressure opening and closing structure. The defects that after the penetrating liquid cooling case of the electronic equipment in the prior art is disconnected from an external liquid cooling pipeline, the balance of internal and external pressure of the case and proper storage of outflow residual cooling liquid cannot be guaranteed simultaneously are overcome; the pressure relief and liquid filling device can adapt to change in internal and external pressure difference of the case, and releases pressure; and meanwhile, the residual cooling liquid in the case can be stored properly.

Description

Technical field[0001]The present invention relates to an apparatus relating to an adaptive pressure relief and a fluid device of an electronic device, which is particularly applicable to the penetrating liquid cooling chassis of the electronic device to disconnect with the external liquid cold line. Adaptive pressure and fluid device.Background technique[0002]As people's constant pursuit of electronic equipment and the development of technology, electronic equipment is increasingly variable, and the order is high, the volume is compact, and the assembly density of components is constantly improving, and the total electronic equipment chassis The heat consumption and heat-current density require the cooling requirements. Natural heat dissipation or forced air cooling can no longer meet the heat dissipation requirements of these electronic devices. The liquid is much more than air, and the liquid medium can be cooled by the liquid medium, and the penetrating liquid cooling chassis can...

AI Technical Summary

Problems solved by technology

[0005] The technical problem solved by the present invention is to provide an adaptive pressure relief and liquid storage device for penetrating liquid-cooled chassis of electronic equipment, which overcomes the disconnection of the penetrating liquid-cooled chassis of electronic equipment and the external liquid cooling pipe in the prior art. After the circuit is connected, the pressure balance inside and outside the chassis cannot be ensured and the residual coolant flowing out is properly stored. The pressure difference can adapt to the change in the pressure difference inside and outside the chassis and release the pressure, and at the same time, it can properly contain the leakage of the residual coolant in the chassis.
