Dimming module heat dissipation device

The utility model discloses a dimming module heat dissipation device, which belongs to the technical field of heat dissipation equipment, and comprises a water pump box, a liquid cooling pipe and a heat dissipation block, a motor is movably installed at the top of the water pump box, a liquid conveying water pump is movably installed at the lower end of the motor, and the liquid cooling pipe is arranged at the front end of the water pump box. By arranging the water pump box, an air cooling device is replaced with water cooling heat dissipation with higher quietness, the water cooling heat dissipation device fixes the module through a heat absorption groove, and then heat energy of the module is completely guided into a heat dissipation block. The cooling liquid in the heat dissipation block can quickly conduct heat energy to the internal heat conducting sheet, the heat energy is volatilized into the air from the heat conducting sheet, so that the quiet effect is achieved, the motor works to drive the infusion
