Description

Technical Field

[0001] The utility model relates to the technical field of computer host heat dissipation, and particularly relates to a double-sided water-cooled circulation heat dissipation system. Background Technique

[0002] With the development of science and technology and network technology, computers have become an indispensable product in the lives and work of Chinese people. In recent years, the e-sports industry has risen rapidly, making computers required to have more powerful performance. However, the higher the computer performance, the higher the heat generated by the heat-generating components on the circuit board (for example: processors, power supplies, and display adapters). Heat has a considerable impact on the usage efficiency and service life of the computer. Therefore, it is necessary to enable the heat-generating components of the computer to obtain good cooling effects to ensure the smooth and stable operation of the computer.

[0003] Currently, the methods with better heat dissipation efficiency mostly install water-cooling heads on the heat-generating components of the circuit board. The water-cooling heads provide water-cooling liquid inside. The water-cooling liquid flows through the heat dissipation pipeline to the heat-generating components to cool their heat, and the cooled water-cooling liquid is then transported back to the water-cooling head to complete the effect of water-cooled circulation heat dissipation. However, most of the existing water-cooled circulation heat dissipation systems adopt a single-sided contact structure with the heat-generating components of the motherboard. The heat dissipation efficiency of this heat dissipation structure is not fast enough to meet the requirements of high-performance heat dissipation. Therefore, we propose a double-sided water-cooled circulation heat dissipation system. Content of the Utility Model

[0034] During actual use, water cooling devices are installed on both sides of the circuit board, and the circuit board is provided with a diversion device communicating with the two water cooling devices. Through the diversion device, the water cooling liquid inside the water cooling device on one side of the main board 1 is quickly guided to the inside of the water cooling device on the other side.
