Problems solved by technology

The problem with the existing quick connector male is that: when debugging the cold plate, the interior of the cold plate will be filled with coolant. After the debugging, usually the quick connector female and the quick connector male are directly disconnected. 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 rupture and leak if it is severe. Both of these situations will directly lead to the scrapping of the cold plate

Embodiment Construction

[0017] Examples of quick connector males Figure 1~5 Shown: the male housing 6 including the movable sealing sleeve for pushing the corresponding quick joint female head at the front end, the rear end of the male housing 6 is provided with an external thread 9 for connecting with the corresponding cold plate, inside the male housing There is a male head fluid channel that runs through the male head housing along the front and rear directions. The front end of the male head fluid channel guides and seals and is slidably equipped with a male head valve core that is pushed by the female head valve core of the quick connector female head. The male head valve core A male spring 8 is arranged between the male housing and the male housing. On the inner wall of the male housing, there is a tapered hole wall section 7 whose diameter gradually increases from front to back, and the tapered hole wall section of the housing cooperates with the male valve core to limit the forward movement ...

Abstract

The invention relates to a male joint of a fast connector. The male joint of the fast connector comprises a male joint shell, a male joint valve element is movably assembled in a male joint fluid channel of the male joint shell in a guiding mode, a pressure relief channel used for connecting the male joint fluid channel and the outside atmosphere is arranged in the male joint valve element and comprises a liquid passing hole segment connected with the male joint fluid channel and an installing hole segment connected with the outside atmosphere, a plugging piece is movably assembled in the installing hole segment in a guiding mode, a pressure relief spring used for applying elastic acting force to the plugging piece and enabling the plugging piece to plug the liquid passing hole segment is arranged on the male joint valve element, and a guiding channel used for connecting the liquid passing hole segment and the installing hole segment after the plugging piece is separated from the liquid passing hole segment is arranged on the plugging piece and the male joint valve element or between the plugging piece and the male joint valve element. The male joint of the fast connector can perform automatic pressure relief.

Description

technical field [0001] The invention relates to a quick connector male 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. A quick connector male connected to the inner cavity of the cold plate is set on the cold plate. When debugging, the quick connector female is connected to the quick connector male. Through the quick connector female, the quick The male connector 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 passing the test, disconnect the quick connector male and the quick connector female, and the cold plate...
