Female head of quick coupling

Abstract

The invention relates to a female head of a quick coupling. The female head comprises a female head shell, wherein a female head valve core and a movable seal sleeve are movably assembled in a female head fluid passage of the female head shell in a guide manner; a female head spring is abutted between the movable seal sleeve and the female head valve core; a sealing section, which is in seal fit with a sealing structure of the seal sleeve to seal the female head fluid passage when being located at a backward limit position, is arranged at the periphery of the female head valve core; a pressure relief section, which is positioned on the rear side of the sealing section for forming a pressure relief passage with the sealing structure of the seal sleeve after the female head valve core moves forwards, is also arranged at the periphery of the female head valve core. The invention provides the female head of the quick coupling capable of realizing automatic pressure relief.

Description

technical field

[0001] The invention relates to a quick connector female head. Background technique

[0002] In the liquid cooling system, the key component of heat dissipation is the cold plate. When in use, the heat-generating device is closely mounted on the cold plate, so as to achieve heat exchange with the cooling liquid flowing in the cold plate to obtain heat dissipation. Therefore, the cold plate The flatness of the cold plate is a key parameter of the cold plate. Set the quick connector female head connected to the inner cavity of the cold plate on the cold plate. When debugging, connect the quick connector male head to the quick connector female head. Through the quick connector male head, quick The connector female injects coolant into the inner cavity of the cold plate, and conducts a tightness test and a thermal performance test on the coolant inside the cold plate. After the test is passed, disconnect the quick connector male and the quick connector female, an...
