[0008] Preferably, a heat conducting plate is placed inside the bellows, and the position of the heat conducting plate is between the air outlet and the pipe.

[0014] (2) In the leak-proof water-cooled graphics card radiator, the water pump increases the fluidity of the coolant in the pipe in the cold head, and at the same time, the fan cools down the coolant in the pipe when it is working, thereby improving the heat dissipation efficiency of the radiator.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

[0022] See also Figure 1-5The utility model provides a technical solution: a liquid-leakage-proof water-cooled graphics card radiator, comprising a cold head 2 and a protection plate 6, the protection plate 6 is rotatably mounted on the surface of the cold head 2, a liquid inlet pipe 3 and a liquid outlet pipe 4 are fixedly mounted on the surface of the cold head 2, the liquid inlet pipe 3 and the liquid outlet pipe 4 are connected inside the cold head 2, a rubber ring 10 is sleeved on the liquid inlet pipe 3 and the liquid outlet pipe 4, a water pump 5 is fixedly mounted on the surface of the liquid outlet pipe 4, the water pump 5 is powered on, the liquid inlet pipe 3 and the liquid outlet pipe 4 are connected through a pipeline, the liquid inlet pipe 3, the liquid outlet pipe 4 and the water pump 5 are connected, and contain cooling liquid inside, a bellows 1 is arranged on the surface of the pipeline, an air outlet is opened on the top of the bellows 1, a bracket 12 is fixedly mounted on the inner wall of the air outlet, a fan 13 is rotatably mounted on the surface of the bracket 12, the fan 13 is powered on, and when the cooling liquid flows in the cold head 2, the heat generated by the graphics card core at the bottom of the cold head 2 can be exported.

[0023] Two groups of protection plates 6 are symmetrically arranged on the surface of the cold head 2. After the protection plates 6 are closed, the rubber ring 10 is pushed to close the protection plates 6, so that a closed space is formed between the protection plates 6 and the cold head 2 to prevent leakage at the connection between the liquid inlet pipe 3 and the liquid outlet pipe 4 and the cold head 2 and corrode the PCB board.

[0024] A heat conducting plate 11 is placed inside the bellows 1, and the position of the heat conducting plate 11 is between the air outlet and the pipe. The side of the heat conducting plate 11 close to the pipe is in contact with the pipe. The heat conducting plate 11 improves the heat flow between the pipe and the air outlet, and improves the heat dissipation of the coolant in the pipe by the fan 13.

[0025] A fixing block 7 is fixedly installed on the surface of the cold head 2. An opening is opened on the surface of the fixing block 7. A screw 9 is sleeved on the inner wall of the opening. The screw 9 is connected to the fixing block 7 through a buffer spring 8. The screw 9 fixes the cold head 2 on the PCB board where the graphics card core is located.

[0026] An oil tank 14 is fixedly mounted on the surface of the bellows 1, a discharge port is provided at the bottom of the oil tank 14, and lubricating oil is contained in the oil tank 14. A gear ring 15 is rotatably mounted on the surface of the bellows 1, and the top of the gear ring 15 contacts the bottom of the oil tank 14, an oil inlet 18 is provided at the top of the gear ring 15, a dropper 19 is fixedly mounted on the inner wall of the gear ring 15, an oil outlet 21 is provided at a section of the dropper 19 away from the gear ring 15, the oil outlet 21 is communicated with the oil inlet 18 through the dropper 19, and the lubricating liquid in the oil tank 14 drips onto the bearing surface of the fan 13 through the dropper 19 to lubricate the bearing of the fan 13.

[0027] A tooth block 20 is fixedly mounted on the outer wall of the gear ring 15, a push-pull rod 16 is fixedly mounted on the surface of the heat conducting plate 11, and a bump 17 is fixedly mounted on the surface of the push-pull rod 16. The bump 17 pushes the tooth block 20 to move during movement, and the moving tooth block 20 drives the gear ring 15 to rotate.

[0028] During operation, confirm the graphics card core that needs water cooling, align the bottom of the cold head 2 with the core and slowly place the cold head 2 on the surface of the core, align the screw 9 with the fixing hole on the graphics card PCB where the core is located, and after the screw 9 is aligned with the fixing hole, twist the screw 9 to make the screw 9 enter the fixing hole to fix the cold head 2. At the same time, in the process of the screw 9 entering the fixing hole, the buffer spring 8 buffers part of the pressure from the screw 9 to prevent the screw 9 from suddenly pressing down and damaging the PCB.

[0029] After the installation of the cold head 2 is completed, the air box 1 is installed at the heat dissipation port of the host chassis, with the air outlet facing the heat dissipation port of the chassis.

[0030] After the cold head 2 and the bellows 1 are installed, the liquid inlet pipe 3 and the liquid outlet pipe 4 are adjusted to a suitable position that does not affect the operation of the equipment, and the protection plate 6 is rotated to make the two groups of protection plates 6 close to each other. After the protection plates 6 are closed, the rubber ring 10 is pushed to the top of the protection plate 6 to cover the protection plate 6, so that a closed space is formed inside the protection plate 6, and the connection between the liquid inlet pipe 3 and the liquid outlet pipe 4 and the cold head 2 is in the closed space, so as to prevent the coolant flowing in the cold head 2 from leaking from the connection and causing a short circuit on the PCB board.

[0031] Furthermore, the radiator is connected to a power source, at which time the water pump 5 and the fan 13 start working. The started water pump 5 pumps out the coolant in the cold head 2 through the liquid outlet pipe 4. The pumped coolant flows into the water pump 5 through the pipeline, and then is pumped into the cold head 2 through the liquid inlet pipe 3 through the water pump 5. This cycle increases the fluidity of the coolant in the cold head 2 and improves the heat dissipation effect of the cold head 2 on the graphics card core.

[0032] Furthermore, when the fan 13 rotates, the coolant flowing into the pipeline can be cooled, and at the same time, the heat conducting plate 11 can increase the heat dissipation speed of the coolant in the pipeline.

[0033] When the heat conduction efficiency of the heat conduction plate 11 decreases and a new heat conduction plate 11 needs to be replaced, the old heat conduction plate 11 is pulled out and the new heat conduction plate 11 is inserted into the bellows 1. In the process of placing the new heat conduction plate 11 into the bellows 1, the movement of the heat conduction plate 11 drives the push-pull rod 16 to move, and the moving push-pull rod 16 drives the protrusion 17 to move. When the protrusion 17 moves, it contacts the gear block 20 and pushes the gear block 20 to move. The moving gear block 20 drives the gear ring 15 to rotate, and the rotating gear ring 15 aligns the oil inlet 18 with the discharge port. The lubricating liquid in the oil tank 14 flows into the oil inlet 18 through the discharge port, and the lubricating oil entering the oil inlet 18 drips from the oil outlet 21 through the dropper 19 and falls onto the surface of the fan 13 bearing, thereby lubricating the fan 13 bearing and preventing the aging of the bearing from affecting the normal rotation of the fan 13 and reducing the overall heat dissipation effect of the radiator.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
