These thermally conductive silicone pads 392 are spaced apart on the lower surface of the arc-shaped cooling box 38 and are fixedly connected to it. A heat dissipation box 35 is also provided above the liquid storage tank 31.

[0026] The working principle and usage process of this utility model are as follows: When in use, the heat dissipation box 35 is installed and fixed so that the main shaft of the centrifugal fan passes through the heat dissipation box 35. At the same time, the arc-shaped cooling box 38 is fixed on the top of the centrifugal fan motor. When the centrifugal fan is working, the power supply of the water pump 393 is turned on. At this time, the water pump 393 delivers coolant 395 to the distribution box 32. Then, the coolant 395 flows continuously through the heat dissipation box 35 and the arc-shaped cooling box 38, thereby achieving synchronous cooling of the main shaft and motor of the centrifugal fan.

[0027] During the operation of the cooling device, the power supply to the thermoelectric cooler 30 and the cooling fan 5 is turned on. At this time, the thermoelectric cooler 30 cools the liquid storage tank 31. In combination with the use of the heat-conducting fins 396, the coolant 395 in the liquid storage tank 31 is cooled down quickly. At the same time, the cooling fan 5 dissipates heat from the hot end of the thermoelectric cooler 30, thereby ensuring the cooling effect of the thermoelectric cooler 30.

[0028] Thus, through the coordinated operation of multiple structures, the cooling device can simultaneously cool the motor and main shaft of the centrifugal fan, resulting in a better cooling effect on the centrifugal fan. Secondly, this invention can be applied to different models of centrifugal fans, making the application range of the cooling device wider. In addition, this invention has anti-slip and warning functions, enriching the functionality of the cooling device. Furthermore, this invention has a simple structure, is easy to use, and is worthy of promotion and use.

[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
