Abstract
Description
Technical fields:
[0001] This utility model relates to the field of hardware accessories technology, and more specifically to a disc-type liquid cooling radiator. Background technology:
[0002] In some existing electrical equipment, heat dissipation devices are required to be installed in the internal control motherboard and other controllers to achieve heat dissipation. These devices are generally a combination of heat sink and cooling fan.
[0003] Existing heat sinks generally consist of multiple heat dissipation fins formed on an aluminum alloy heat sink to achieve heat dissipation. Some circular controllers or motherboards typically have circular heat sinks with fixed or formed heat dissipation fins on them. They use air cooling, which generally has a poor heat dissipation effect.

[0024] The above structure is formed by machining three parts into a circular bottom block 10 and then welding them together. The circular bottom block 10 can also be made as a whole by metal 3D printing.
[0025] Furthermore, both the upper circular cavity 11 and the lower circular cavity 12 have outwardly extending connecting through holes formed on their inner sidewalls. The outer end of the connecting through hole extends out of the outer sidewall of the middle circular block 15. The inner ends of the liquid inlet connector 14 and the liquid outlet connector 13 are inserted into the corresponding connecting through holes, and their outer sidewalls are welded and fixed to the inner sidewall of the corresponding connecting through hole.
[0026] The upper cover plate 16 has a plurality of vertical screw-in holes 161 formed thereon, and the bottom plate of the vertical heat dissipation pipe 20 has a screw-in pipe portion extending downward thereon in the middle, and the screw-in pipe portion is screwed into the corresponding vertical screw-in hole 161.
[0027] Furthermore, the bottom edge of the base plate of the vertical heat dissipation pipe 20 is formed with an annular groove, the sealing gasket is nested in the annular groove, the bottom surface of the sealing gasket presses against the top surface of the upper cover plate 16, and the top surface of the sealing gasket presses against the top surface of the annular groove.
[0028] The bottom surface of the upper circular cavity 11 is formed with multiple stepped through holes, the upper part of which is a large-diameter hole section and the lower part is a small-diameter hole section. The inner sidewall of the large-diameter hole section is formed with internal threads. The inner heat exchange tube 30 is inserted into the vertical heat dissipation tube 20, and its top surface presses against the middle of the bottom surface of the top plate of the vertical heat dissipation tube 20. The lower part of the vertical heat dissipation tube 20 extends out of the corresponding vertical screw-in through hole 161 and the upper circular cavity 11. The lower screw-in tube part formed in the middle of the bottom end plate is screwed onto the internal thread of the corresponding large-diameter hole section.
[0029] The bottom edge of the bottom plate of the inner heat exchange tube 30 is formed with an annular groove in which a second sealing ring 2 is nested. The top surface of the second sealing ring 2 presses against the top surface of the annular groove, and its bottom end surface presses against the bottom surface of the upper circular cavity 11.

[0034] A cooling fan is also fixed on the side wall of the water tank to dissipate heat from the returning water.
[0035] In use, the water in the tank is pumped to the lower circular cavity 12, where it exchanges heat with the components that need heat dissipation, which are in close contact with or fixed to the bottom surface of the circular bottom block 10. After that, the water enters all the internal heat exchange tubes 30 and then enters the vertical heat dissipation tubes 20, where it exchanges heat with the flowing air outside. A guide fan is also installed on the mounting mechanism (such as the chassis) on the outside of the vertical heat dissipation tubes 20, which blows air onto the vertical heat dissipation tubes 20 to achieve rapid heat exchange. Then, the water flows back to the tank, where it is cooled by the cooling fan before being transported to the circular bottom block 10 for heat exchange, which greatly improves the heat exchange effect.
