[0002] The computational demands of computer systems are becoming increasingly enormous, with multiple circuit boards often housed within a single chassis to handle different tasks, such as image processing and signal processing. For rapid heat dissipation, the cooling structure is crucial for the stability of computer systems, and the application of liquid cooling systems within chassis is becoming increasingly widespread. The main component of a liquid cooling structure is the liquid cooling heat dissipation assembly, which includes heat-absorbing components that rest against the heat-generating elements on the circuit board and rapid heat exchange components installed in available space within the chassis. The rapid heat exchange components and heat-absorbing components are connected by piping, which has fluid connectors. These fluid connectors are inserted and fixed into the liquid cooling sockets of the rapid heat exchange components or heat-absorbing components. Currently, fluid connectors are mainly fixed using threaded connections. However, given the limited space inside the computer case, threaded connections make installation and removal of fluid connectors cumbersome.

[0020] Example: See Figures 1 to 4 As shown, a quick-release fluid connector for computer heat dissipation includes a straight pipe-shaped movable connector 1. The front end of the movable connector 1 is formed with an outer screw sleeve 11. A rubber sealing sleeve 2 is inserted into the movable connector 1 on the rear side of the outer screw sleeve 11. An arc-shaped annular groove 21 is formed on the inner wall of the middle part of the rubber sealing sleeve 2. The front end of the rubber sealing sleeve 2 is inserted and fixed inside the outer screw sleeve 11 of the movable connector 1, and the rear end of the rubber sealing sleeve 2 is inserted and fixed inside a locking sleeve 5, which is fitted onto the movable connector 1. A front positioning retaining ring 3 is inserted and fixed on the movable connector 1 on the rear side of the locking sleeve 5. Guide inserts are formed on both sides of the front positioning retaining ring 3. The locking sleeve 5 has guide arms 51 formed on its rear end faces on both sides. The rear end of the guide arm 51 passes through the guide slot 31 of the front positioning retaining ring 3 and is hinged to the front connecting rod 6 via a front hinge pin. The rear end of the front connecting rod 6 is hinged to the rear connecting rod 7 via a rear hinge pin. When the front connecting rod 6 and the rear connecting rod 7 are aligned (the front connecting rod 6 and the rear connecting rod 7 are on the same straight line, and the included angle between them is 180 degrees), the locking sleeve 5 can be driven to move forward. The locking sleeve 5 will compress the rubber sealing sleeve 2, and the outer wall of the part of the rubber sealing sleeve 2 with the annular groove 21 will deform and change into an annular convex retaining ring a. Figure 3 As shown;
[0021] A rear positioning retaining ring 4 is inserted and fixed on the moving pipe 1 on the rear side of the front positioning retaining ring 3. The rear positioning retaining ring 4 has openings 41 on both sides that are opposite to the guide arm 51. The rear end of the rear connecting rod 7 is inserted into the opening 41 of the rear positioning retaining ring 4 and a positioning pin 9 is inserted. The two ends of the positioning pin 9 are inserted and fixed on the rear positioning retaining ring 4. A paddle 8 is inserted on the positioning pin 9 in the opening 41 and the paddle 8 is fixed to the rear end of the rear connecting rod 7.
[0022] A fixed sleeve 10 is inserted into the movable pipe 1 on the rear side of the rear positioning retaining ring 4. The inner wall of the rear end of the fixed sleeve 10 is formed with pipe threads. The inner wall of the front end of the fixed sleeve 10 is formed with a front limiting retaining ring 101. A sealing ring 20 is fixedly connected to the inner wall of the front limiting retaining ring 101. The sealing ring 20 is pressed against the outer wall of the movable pipe 1. A rear limiting retaining ring 12 is formed on the outer wall of the rear end of the movable pipe 1, which is opposite to the front limiting retaining ring 101.
[0023] A semi-circular guide head is formed between the front end of the outer rotating sleeve 11 and the front end of the moving pipe 1. The front and rear ends of the rubber sealing sleeve 2 are respectively formed with annular connecting sleeves. An annular groove is formed on the front end face of the locking sleeve 5. The connecting sleeves at the front and rear ends of the rubber sealing sleeve 2 are respectively inserted and fixed into the outer rotating sleeve 11 and the groove of the locking sleeve 5. The outer walls of the rubber sealing sleeve 2, the outer walls of the outer rotating sleeve 11, and the outer walls of the locking sleeve 5 are all within the same cylindrical surface. Therefore, the front end of this fluid connector can be smoothly inserted into the liquid coolant of the computer host. Inside the socket of the thermal component; the socket on its liquid cooling heat dissipation component can be a straight socket, the optimal socket is a hole with a stepped surface, that is, the socket has two sections, the diameter of the section of the hole near the socket outlet is smaller than the diameter of the other section of the hole away from the socket outlet, then there is a stepped surface between the two sections of the hole, and the rubber sealing sleeve 2 on this fluid connector moves into the section of the hole inside the socket. When the rubber sealing sleeve 2 deforms, the retaining ring a will press against the inner wall of the hole, and at the same time, the stepped surface inside the socket can restrict the outward movement of the retaining ring a.
[0024] The diameter of the inner wall of the locking sleeve 5 is equal to the diameter of the outer wall of the movable pipe 1. There is a gap between the movable pipe 1 and the front positioning retaining ring 3. Only with a gap between the two can the locking sleeve 5 be driven to move axially on the movable pipe 1.
[0025] The rear end of the guide arm 51 on the locking sleeve 5 is formed with a slot 52. The front end of the front connecting rod 6 is inserted into the slot 52 of the guide arm 51 and a front hinge pin is inserted therein. The two ends of the front hinge pin are respectively inserted and fixed on the guide arm 51. The rear end of the front connecting rod 6 is inserted with a rear hinge pin. The two ends of the rear hinge pin are inserted and fixed on the two ends of the rear connecting rod 7. The paddle 8 is inserted and fixed between the rear connecting rods 7 and is perpendicular to the rear connecting rods 7.
[0026] A protective sleeve 30 is inserted and fixed on the front positioning retaining ring 3, and the front end of the protective sleeve 30 is fixed on the rear end face of the front positioning retaining ring 3; a rubber anti-slip sleeve 40 is inserted and fixed on the protective sleeve 30, and the rubber anti-slip sleeve 40 and the protective sleeve 30 are respectively formed with clearance openings opposite to the front connecting rod 6, the rear connecting rod 7 and the paddle 8. The main function of the protective sleeve 30 is to facilitate the gripping of this fluid connector.
[0027] The diameter of the outer wall of the rear limiting ring 12 at the rear end of the moving pipe 1 is equal to the diameter of the inner wall of the fixed sleeve 10.
[0028] The pipe thread on the fixed sleeve 10 is located on the rear side of the moving pipe 1. There is a gap between the front limiting ring 101 of the fixed sleeve 10 and the rear limiting ring 12 of the moving pipe 1. The moving pipe 1 can move telescopically within the fixed sleeve 10. The length of the fixed sleeve 10 inserted into the moving pipe 1 must be at least greater than the length of the rubber sealing sleeve 2. This also allows the rubber sealing sleeve 2 on the moving pipe 1 to be fully inserted into the socket of the liquid cooling heat dissipation component on the computer host.
[0029] Working principle: This invention is a quick-release fluid connector. The structure of the quick-release fluid connector is shown in the attached figure. The fluid connector in the attached figure is a schematic diagram of the locked state. The rubber sealing sleeve 2 has a deformed retaining ring a, which can be locked into the insertion hole of the liquid cooling heat dissipation component. The self-locking structure composed of the rear connecting rod 7 and the front connecting rod 6 can restrict the locking sleeve 5 from moving back on the moving pipe 1, thereby preventing the retaining ring a from disappearing.
[0030] When it is necessary to disconnect the fluid connector, by moving the lever 8, the rear connecting rod 7 is driven to rotate around the positioning pin 9 to both sides of the moving pipe 1. The rotation of the rear connecting rod 7 can drive the front connecting rod 6 to rotate and move. The front connecting rod 6 can pull the locking sleeve 5 and move it, thereby straightening the rubber sealing sleeve 2. After the rubber sealing sleeve 2 is deformed, the retaining ring a will disappear. Then the moving pipe 1 is moved as a whole, and the moving pipe 1 can retract into the fixed sleeve 10, so that the fluid connector can be removed from the liquid cooling heat dissipation assembly.
[0031] The embodiments described are illustrative of the invention and are not intended to limit the invention. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the invention; therefore, the scope of protection of the invention should be as set forth in the claims.
