[0027] The circulation assembly 8 includes a circulating water pump 801, which is fixedly connected to the upper surface of the cooling water tank 5. The surface of the circulating water pump 801 is connected to a water inlet pipe 802, which is connected to the hollow shell 2. The circulating water pump 801 is connected to the cooling water tank 5. The surface of the hollow shell 2 is connected to a water outlet pipe 803, which is connected to the cooling water tank 5. One side of the cooling water tank 5 is connected to a circulating pipe 804, and the circulating pipe 804 is connected to heat sinks 805 in an equidistant array. The circulating water pump 801 drives the coolant to circulate, allowing the coolant to continuously absorb heat in the hollow shell 2 to ensure the heat dissipation effect.

[0028] The cooling water tank 5 is provided with a filter assembly 9, which includes a limit frame 901, which is fixedly connected to one side of the cooling water tank 5, a fixing frame 902 is clamped on one side of the limit frame 901, and a filter screen 903 is fixedly connected inside the fixing frame 902. The air is filtered by the filter screen 903 to prevent dust from falling on the surface of the heat sink 805 and causing a decrease in heat exchange efficiency.

[0029] The fixing frame 902 and the limiting frame 901 are arranged correspondingly, and the fixing frame 902 and the heat sink 805 do not contact each other.

[0030] Among them, a mounting plate 806 is fixedly connected to one side of the cooling water tank 5, a motor 807 is fixedly installed on the mounting plate 806, and a fan blade 808 is fixedly connected to the output shaft end of the motor 807. The fan blade 808 is driven by the motor 807 to rotate, thereby accelerating the flow of air and improving the heat exchange efficiency at the heat sink 805.

[0031] The fan blade 808 does not contact the heat sink 805, the fan blade 808 does not contact the connecting plate 10, and the heat sink 805 is a hollow copper heat sink.

The coolant circulates under the action of the circulating water pump 801, and the coolant flows out of the hollow shell 2, enters the cooling water tank 5 through the outlet pipe 803, flows into the heat sink 805 through the circulating pipe 804, and exchanges heat with the external air in the heat sink 805.
