Problems solved by technology

[0004] Traditional liquid-cooled heat dissipation systems generally use pure liquid as the working fluid, but the thermal conductivity of pure liquid is generally small, and the thermal resistance between it and the heat-absorbing unit, heat dissipation unit, and the pipe wall of the connecting pipe is large, resulting in the working fluid of the liquid-cooled heat dissipation system It cannot quickly absorb heat from the heat-absorbing unit and dissipate heat to the heat-dissipating unit, thereby affecting the heat transfer of the liquid-cooled heat dissipation system and reducing the heat dissipation efficiency

Description

【Technical field】 [0001] The invention relates to the field of heat transfer, in particular to a liquid-cooled heat dissipation system. 【Background technique】 [0002] In recent years, with the rapid development of electronic technology, the operating frequency and speed of electronic components have been continuously improved. However, at the same time, the electronic components generate more and more heat and the temperature is getting higher and higher, which seriously threatens the performance and stability of the electronic components during operation. In order to ensure the normal operation of the electronic components, it is necessary to effectively dissipate heat from the electronic components. At present, the air-cooled heat dissipation system is widely used in the heat dissipation of electronic components. It generally conducts the heat generated by the heating element through the heat dissipation fins, and then uses the fan to force the air convection to take away...
