Problems solved by technology

[0011] Compared with the traditional air-cooled heat dissipation system, the high-power LED liquid-cooled heat dissipation system disclosed in the above reference document 3 has improved heat dissipation efficiency, but the energy consumption is also higher
Moreover, the liquid cooling system provided in this reference document only has a heat sink module, which can conduct the heat of the LED to the inside of the heat sink, and take away the heat under the action of circulating water. For high-power LEDs, other Cooling efficiency is still limited
