Problems solved by technology

The problem with the existing quick connector female head is that when the cold plate is being debugged, the inside of the cold plate will be filled with coolant. The interior of the board is still filled with coolant. If it is stored or transported directly, the coolant will expand when the temperature rises. This expansion is inevitable and quite strong. The expanded coolant volume increases. When the coolant is full When the container is closed, the pressure will increase sharply, which will cause the surface of the cold plate to deform and bulge if it is light, and cause the cold plate to break and leak if it is severe. Both of these situations will directly lead to the scrapping of the cold plate

Embodiment Construction

[0014] An example of a quick connector female head Figure 1~5 Shown: including the female head housing 5, the front end of the female head housing 5 is a plug-in end for plugging with the adapted quick connector male head, and the outer peripheral surface of the rear end of the female head housing is provided with a Connecting thread 6 for plate connection. The female head housing is provided with a female head fluid passage that runs through the female head housing along the front and back directions. The female head spool 10 is equipped with a female head spool for pushing the male head spool of the quick connector male head, and the female head is guided to move in the female head fluid channel. The housing 5 is provided with a spool limiting structure for cooperating with the female spool so that the female spool can move backwards to the limit. The circlip 9 of the female head fluid channel is provided with a limit step 8 for limiting cooperation with the rear end of th...

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...
