A pressure relief joint and a liquid cooling assembly using the pressure relief joint

Abstract

The invention relates to a pressure relief joint and a liquid cooling component using the same in order to guarantee the leakproofness of the liquid cooling component in normal work. The pressure relief joint comprises a joint seat which is hermetically installed on a cooling liquid chamber body; the joint seat is provided with a pressure relief passage which communicates with the inside of the cooling liquid chamber body; the pressure relief joint further comprises a pressure relief valve core which is movably installed inside the joint seat in a guiding manner; the pressure relief valve corecomprises a sealing position and a pressure relief position, wherein the sealing position is positioned in a movement stroke and is used for sealing the pressure relief passage; the pressure relief position is used for opening the pressure relief passage; the pressure relief joint further comprises a locking part which is used for matched with the pressure relief valve core in a stop manner in order to keep the pressure relief valve core at the sealing position; the locking part is detachably installed or movably installed on the joint seat; and the locking part which is movably installed onthe joint seat comprises an avoiding position which is separated from the pressure relief valve core in a stop manner. By additionally arranging the locking part, the pressure relief joint has the pressure relief function without affecting the normal use of the liquid cooling component, and does not cause leakage of cooling liquid.

Description

technical field

[0001] The invention relates to a pressure relief joint and a liquid cooling assembly using the pressure relief joint. Background technique

[0002] For electronic equipment using liquid cooling, when it is necessary to debug or transport the liquid cooling components, the liquid cooling components are usually disassembled from the equipment. After disassembly, the inside of the liquid cooling components is a closed space filled with liquid . When the temperature of the external environment rises, the liquid pressure inside the liquid-cooled component will increase sharply. In extreme cases, the flow channel in the liquid-cooled cold plate will bulge, the seal will fail, and leakage will occur. In order to prevent this problem from happening, the operator needs to drain the disassembled liquid cooling components one by one, so as to avoid the pressure increase of the liquid inside the liquid cooling component as the temperature increases, but this operation ...
