[0028] Please refer to Figures 1 to 7 , in the embodiment of the present invention, a water cooling system includes a water cooling head 7 and a fixed disk 4. The fixed disk 4 is connected with a liquid guide hose 5 through a pumping device

[0029] Specifically, the pumping device includes a disc cavity, which is opened in the fixed disk 4. A circular plate 11 is rotatably connected to the middle of the disc cavity. An annular cavity is formed between the circumferential outer side of the circular plate 11 and the inner side wall of the disc cavity. A middle section of the liquid guiding hose 5 is located in the annular cavity. Both ends of the liquid guiding hose 5 extend through the side wall of the fixed disk 4. Two extrusion blocks 13 are fixedly connected to the circumferential side wall of the circular plate 11. A fixed cylinder 3 is fixedly connected to the outer wall of the fixed disk 4. A motor 12 is fixedly connected to the interior of the fixed cylinder 3. The output of the motor 12 The output shaft is fixedly connected with a rotating rod 9, which penetrates and is rotatably connected to the two side walls of the fixed disk 4, and the rotating rod 9 penetrates and is fixedly connected to the circular plate 11. The end of the rotating rod 9 away from the motor 12 is fixedly connected with a fan blade 10, and the fan blade 10 faces one side of the heat dissipation spiral tube 1. When the motor 12 drives the rotating rod 9 to rotate, the rotating rod 9 can drive the circular plate 11 to rotate, and the rotation of the circular plate 11 can drive the two extrusion blocks 13 to alternately circulate and squeeze the liquid guiding hose 5 in the annular cavity, so that the coolant in the liquid guiding hose 5 flows;

[0030] Two oppositely arranged magnetic plates 2 are fixedly connected to the side wall of the fixed disk 4, and a heat dissipation spiral tube 1 is arranged between the two magnetic plates 2. The heat dissipation spiral tube 1 and the water cooling head 7 are both made of copper with high thermal conductivity. The two ends of the heat dissipation spiral tube 1 respectively penetrate the side walls of the two magnetic plates 2, one end of the heat dissipation spiral tube 1 is connected to the liquid guide hose 5, and the other end of the heat dissipation spiral tube 1 is connected to the delivery hose 6. A spiral channel 8 is opened in the water cooling head 7, one end of the delivery hose 6 penetrates the central upper side of the water cooling head 7 and is connected to the central end of the spiral channel 8, and one end of the liquid guide hose 5 is connected to the outer ring end of the spiral channel 8;

[0031] The heat dissipation spiral tube 1, the liquid guiding hose 5, the spiral channel 8, and the delivery hose 6 are all filled with coolant, which is composed of deionized pure water, a surfactant, and a magnetic ball 14. The surfactant includes any one of oleic acid and linoleic acid. The surfactant is used to prevent the magnetic ball 14 particles from agglomerating to ensure the stability of the coolant fluid. The magnetic ball 14 is composed of gadolinium (Gd), aluminum (Al), cobalt (Co) and zirconium (Zr), and has high magnetic entropy change and magnetocaloric effect. The alloy can absorb or release a large amount of heat under changes in the magnetic field. The magnetic ball 14 is a sphere with dense pits on the surface, and the diameter of the magnetic ball 14 is 0.1-0.2 mm.

[0032] The working principle of the present invention is:

[0033] During use, first, the bottom side of the water-cooling head 7 can be attached to the surface of the computer heating element. Then, start the motor 12. The motor 12 can drive the rotating rod 9 to rotate. The rotation of the rotating rod 9 can drive the circular plate 11 to rotate. The rotation of the circular plate 11 can drive the two extrusion blocks 13 to alternately and cyclically extrude the liquid guide hose 5 in the annular cavity, causing the coolant in the liquid guide hose 5 to flow, and further causing the coolant to circulate along the liquid guide hose 5, the spiral channel 8, the delivery hose 6, and the heat dissipation spiral tube 1.

[0034] And when the rotating rod 9 rotates, it can drive the fan blade 10 to continuously rotate. The rotation of the fan blade 10 can continuously cool the heat dissipation spiral tube 1 by air cooling, reducing the temperature of the coolant in the heat dissipation spiral tube 1. When the coolant enters the heat dissipation spiral tube 1, the magnetic balls 14 in the coolant are in the strong magnetic field between the two magnetic plates 2. The magnetic moments inside the magnetic balls 14 will be rearranged, resulting in a change in magnetic entropy. In order to keep the total entropy of the system unchanged, when the magnetic moments are arranged neatly, that is, when the magnetic entropy decreases, the thermal entropy will increase correspondingly, thus releasing heat. On the contrary, when the magnetic balls 14 leave the heat dissipation spiral tube 1 and the external magnetic field is removed, the magnetic moments of the magnetic balls 14 become disordered again, that is, the magnetic entropy increases and the thermal entropy decreases. The magnetic balls 14 need to absorb heat, and the magnetic balls 14 can play a refrigeration effect. When the magnetic balls 14 enter the water-cooling head 7 with the coolant, the magnetic balls 14 absorb the external heat, greatly improving the heat dissipation effect on the heating element on the bottom side of the water-cooling head 7.

[0035] As described above, it is only the preferred embodiment of the present invention, and there is no restriction in any form on the present invention. Any ordinary technician in the industry can smoothly implement the present invention according to the illustrations in the specification and the above description. However, any equivalent changes made by those skilled in the art within the scope of the technical solution of the present invention by making some changes, modifications, and evolutions using the technical content disclosed above are all equivalent embodiments of the present invention. At the same time, any equivalent changes, modifications, and evolutions made to the above embodiments based on the essential technology of the present invention still fall within the protection scope of the technical solution of the present invention.
