AI Technical Summary
When the data center server works in the liquid-cooled box, the evaporation pressure caused by the vaporization of the coolant is higher than the external atmospheric pressure, which can easily cause coolant leakage, causing waste and environmental impact.
A pressure balance and leakage prevention device including liquid-cooled box, pressure comparison switch, pump, condenser and liquid-phase check valve is designed. The pressure inside the liquid-cooled box is detected by the pressure comparison switch. When the pressure is too high , the vaporized coolant is forced to condense and re-send back to the box to prevent leakage.
It effectively prevents the leakage of coolant, reduces the waste of coolant and environmental impact, and ensures the sealing of the liquid-cooled box.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of data center server boxes, and in particular refers to a pressure balancing and anti-leakage device for an immersion liquid cooling box of a data center server. Background Art
[0002] Data center servers generate a lot of heat when working. In order to reduce the heat, the data center servers are immersed in a liquid cooling box. As the server works, it absorbs the heat released and gradually vaporizes. The vaporization of the phase change coolant will produce evaporation pressure on the closed box. When the evaporation pressure is higher than the external atmospheric pressure, this pressure can easily cause the coolant at the box seal - vaporous fluorinated liquid to leak into the atmosphere, resulting in a waste of expensive coolant and impact on the environment. Utility Model Content
[0003] The technical problem to be solved by the utility model is to provide a pressure balancing and anti-leakage device for an immersion liquid cooling box of a data center server in view of the deficiencies of the above-mentioned prior art.
[0004] In order to solve the above technical problems, the technical solution adopted by the utility model is:
[0005] A pressure balancing and anti-leakage device for an immersed liquid cooling box for a data center server comprises a liquid cooling box, in which a data center server is immersed, a box cover is arranged above the liquid cooling box, the bottom of the box cover is sealed to the liquid cooling box by a sealing strip, a pressure comparison switch, a pump, a condenser and a liquid phase one-way valve are sequentially connected to one side of the upper side of the liquid cooling box through a connecting pipe, and an end of the connecting pipe is connected to the liquid cooling box from the bottom side of the liquid cooling box.
[0006] Furthermore, the pressure comparison switch adopts a TXZC2 type electronic pressure switch.
[0007] Furthermore, the pump is a 2XZ-2 type vacuum pump.
[0008] Furthermore, the condenser is a plate condenser.
[0009] Furthermore, the liquid phase one-way valve adopts a H21W-250P one-way valve.
[0010] Compared with the prior art, the utility model provides a pressure balancing and anti-leakage device for an immersed liquid cooling box for a data center server. It compares the internal pressure of the liquid cooling box through a pressure comparison switch. When the pressure is too high, the vaporized coolant is forced to condense and flow into the liquid cooling box again after being converted into liquid, thereby solving the problem of coolant leakage in the existing box caused by the pressure generated by the vaporization of the coolant being higher than the ambient atmospheric pressure. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] Among them, 1. liquid cooling box body, 2. box cover, 3. pressure comparison switch, 4. pump, 5. condenser, 6. liquid phase one-way valve. DETAILED DESCRIPTION
[0013] The technical solutions in the embodiments of the present utility model will be described clearly and completely below.
[0014] A pressure balancing and anti-leakage device for an immersed liquid cooling box for a data center server comprises a liquid cooling box 1, in which a data center server is immersed, a box cover 2 is arranged above the liquid cooling box 1, a sealing strip is installed at the bottom of the box cover 2, and the box cover 2 is sealed to the liquid cooling box 1 through the sealing strip; a pressure comparison switch 3, a pump 4, a condenser 5 and a liquid phase one-way valve 6 are sequentially connected to one side of the upper side of the liquid cooling box 1 through a connecting pipe, and an end of the connecting pipe is connected to the liquid cooling box 1 from the bottom side of the liquid cooling box 1. Example
[0015] In this embodiment, the pressure comparison switch 3 adopts a TXZC2 type electronic pressure switch, the pump 4 adopts a 2XZ-2 type vacuum pump, the condenser 5 adopts a plate condenser, and the liquid phase one-way valve 6 adopts a H21W-250P one-way valve. During operation, when the coolant vaporizes, pressure is generated in the closed box. The pressure comparison switch 3 compares the pressure. When it is higher than the atmospheric pressure of the external environment of the box, the switch transmits a signal to the pump 4, and the pump 4 starts to work, and the vaporized coolant-fluorinated liquid is forcibly pumped to the condenser 5. Under the heat dissipation effect of the condenser, the vapor coolant is condensed from vapor to liquid, and the volume is also reduced accordingly. Under the action of the pump 4, the liquid coolant opens the liquid phase one-way valve and is sent back to the box. The liquid phase one-way valve 6 is in a closed state when the pump stops working, thereby preventing the pressure generated by vaporization from directly communicating with the box.

Those skilled in the art may make some modifications or changes without departing from the spirit and scope of the present invention, that is, within the scope of disclosure. Therefore, the scope of protection of the present invention shall be subject to the scope defined in the claims.
