Description

One-way sealing quick female joint for self-sealing liquid cooling system

Technical Field

The utility model belongs to the technical field of liquid cooling systems, and particularly relates to a quick female joint of a self-sealing liquid cooling system for realizing quick on-off of liquid conveyed in a pipeline.

Background

With the rapid development of information technology, the service volume of the data center is enlarged and the power density is improved, and liquid cooling becomes a new technology for refrigerating the data center. In a liquid cooling system, a quick connector is used on an outer tube connecting the liquid cooling system and a server. When the liquid cooling system needs to be overhauled and maintained, the outer pipe does not need to be disassembled, the outer pipe can be directly connected or disconnected by plugging and unplugging the quick connector, and liquid leakage cannot occur at the position of the quick connector in the plugging and unplugging process.

At present, the quick connectors used in liquid cooling systems in the market are mostly self-sealing quick connectors. The self-sealing quick connector comprises a plug (male head) and a socket (female head). When the plug and the socket of the quick connector are disconnected, the plug and the socket are automatically closed, self-sealing is realized, and leakage of liquid is prevented. When the plug and the socket of the quick connector are connected, the valve cores of the male head and the female head are contacted and pushed open, and the fluid channel is opened, so that the outer pipe connected with the fluid channel is communicated. The female head comprises a body, a steel ball, a locking ring, a valve core, a spring and the like. The male head comprises a main body, a groove for receiving the locking steel ball, a valve core, a spring and the like. In the off-state, the steel ball is held in the covering position by the locking ring. In the connection state, the locking ring can move between an initial connection position and a locking position, and in the initial connection position, the locking ring retreats, the steel ball is released, and the main body of the male head drives the locking ball outwards; when the locking position is realized, the steel balls of the socket are clamped at the grooves of the plug, the locking ring returns to the covering position, and therefore the steel balls are locked. In the connected state, the spring is compressed and the valve element is pushed open.

The currently available female connectors have several disadvantages:

1) and the steel ball locking structure ensures that the steel ball causes abrasion to other parts of the female head.

2) The steel ball locking structure needs a large number of steel balls, cannot lock the whole surface of the formed product and can only realize local locking of a steel ball area;

3) the steel ball is of a spherical structure, has certain pressure bearing requirements, and is easy to slip when the internal pressure is too high, so that the locking device is ineffective.
