[0002] A fan cooling device is a device used to help the fan dissipate heat or cool down. It can effectively reduce the heat generated when the fan is running, ensure the normal operation of the fan and extend its service life. The fan cooling device mainly cools or dissipates heat for key components such as the motor, bearing seat, blades, etc. in the fan.

[0003] Most fans use natural convection to dissipate heat: when the fan is running, the blades rotate to generate airflow, which can help remove heat from the bearing seat and blades. However, the efficiency of natural convection heat dissipation is relatively low and the speed is slow. Especially under high temperature or high load conditions, it is unable to effectively remove heat from the bearing seat and blades. The heat dissipation is limited, resulting in an increase in the internal temperature of the fan. Therefore, a fan cooling device is urgently needed to solve the above problems.

[0026] Please refer to Figure 1 , Figure 2 , Figure 3In one embodiment, a fan cooling device provided by the present application includes a base 1, a motor 2 and a volute 3, the base 1 is provided with the motor 2 and the volute 3, the volute 3 is provided with a condensation ring 4, the inner ring of the condensation ring 4 is connected to the bearing seat 5, the output shaft of the motor 2 passes through the inner ring of the bearing seat 5 and is connected to a rotating wheel 6, a plurality of blades 7 are arranged on the rotating wheel 6, and a cooling pipe 8 is built in the rotating wheel 6, one end of the condensation ring 4 is connected to the cooling pipe 8, and the other end of the condensation ring 4 is connected to a pumping assembly, the motor 2 and the pumping assembly are electrically connected to a control box (not shown in the figure) arranged on the base 1.

[0027] It can be understood that by utilizing the pumping assembly to transport the coolant to the condensation ring 4 and the cooling pipe 8, the bearing seat 5 and the blade 7 are cooled. Liquid cooling can provide a stronger heat dissipation capacity than natural convection, especially in a high temperature environment. The cooling effect of the condensation ring 4 and the cooling pipe 8 can remove heat more quickly. At the same time, by utilizing the liquid cooling method, the fan structure can be designed to be relatively closed, reducing the impact of dust and pollutants on the operation of the fan.

[0028] For details, please refer to Figure 3 , Figure 4 , Figure 5 On the basis of the above embodiment, a placement groove 11 is opened on the rotating wheel 6, and the cooling pipe 8 is in a spiral shape. The cooling pipe 8 is arranged in the placement groove 11, and the cooling pipe 8 contacts the inner wall of the placement groove 11. The water inlet of the cooling pipe 8 is connected to the water outlet of the condensation ring 4 through the first hose 14. The first hose 14 is arranged inside the volute 3. By adopting the spiral cooling pipe 8, a larger contact area with the rotating wheel 6 can be obtained, and a better heat dissipation effect can be achieved.

[0029] For details, please refer to Figure 4 , Figure 5 On the basis of the above embodiment, it also includes a connecting rod 12 and a support frame 13, the connecting rod 12 is connected to the support frame 13, the support frame 13 is arranged in the placement groove 11, the support frame 13 is connected to the cooling pipe 8, and the connecting rod 12 is connected to the volute 3. It can be understood that the side of the cooling pipe 8 in contact with the support frame 13 is fixedly connected. By setting the support frame 13, a support effect can be provided for the cooling pipe 8 to prevent the cooling pipe 8 from rotating with the rotating wheel 6.

[0030] For details, please refer to Figure 2 , Figure 3 On the basis of the above embodiment, the water pumping assembly includes a water tank 9, a water pump (not shown in the figure) and a water filling pipe 10. The base 1 is provided with a water tank 9, and the water tank 9 is provided with a water pump and a water filling pipe 10. The water pump is electrically connected to the control box.

[0031] It can be understood that the water tank 9 is filled with coolant, and a cooler is built in the water tank 9. The cooler is used to cool the returning coolant, thereby realizing the heat dissipation effect of the liquid cooling cycle. When in use, the coolant is extracted by a water pump, and the heat of the condensation ring 4 and the cooling pipe 8 is taken away by the coolant during the flow of the coolant.

[0032] For details, please refer to Figure 5 , Figure 6 , Figure 7 On the basis of the above embodiment, the water outlet of the cooling tube 8 is connected to the water outlet pipe 20, and the water inlet of the condensation ring 4 is connected to the water inlet pipe 19 through the second hose 15. The water outlet pipe 20 and the water inlet pipe 19 extend to the outside through the volute 3.

[0033] Specifically, based on the above embodiment, a temperature sensor (not shown in the figure) is further included. The temperature sensor is electrically connected to the control box. The temperature sensor is arranged in the rotating wheel 6, and the sensing end of the temperature sensor is in contact with the surface of the cooling tube 8.

[0034] It can be understood that the contact surface of the condensation ring 4 is also provided with a temperature sensor, which can be used to monitor the surface temperature of the condensation ring 4 and the cooling tube 8 in real time, trigger the overheating signal in time and perform liquid cooling to dissipate heat.

[0035] For details, please refer to Figure 1 On the basis of the above embodiment, a protective net 17 is further included. An air inlet 16 is arranged on the volute 3. The protective net 17 is threadedly connected to the air inlet 16. By setting the protective net 17, large foreign objects can be prevented from blocking the air inlet 16 and affecting the air intake of the fan, thereby affecting its working efficiency. At the same time, it can also play a role in safety protection.

[0036] Specifically, based on the above embodiment, the cooling tube 8 is made of copper. It can be understood that the condensation ring 4 is also made of copper, which can well absorb the heat generated by the bearing seat 5 and the blades 7.

[0037] In summary, when a fan cooling device is in use, the motor 2 is used to drive the rotating wheel 6 and the blade 7 to rotate, the air is blown in through the air inlet 16 and discharged from the air outlet 18, and the heat generated by the bearing seat 5 and the blade 7 is absorbed by the high thermal conductivity of the copper material by setting the cooling pipe 8 and the condensation ring 4 made of copper. When the temperature sensor detects that the surface temperature of the cooling pipe 8 exceeds the preset value, a signal is sent to the control box, and the control box controls the water pump to start, and the coolant in the water tank 9 is extracted by the water pump. The coolant enters the condensation ring 4 along the water inlet pipe 19 and then enters the cooling pipe. 8, the heat dissipation of the bearing seat 5 and the blades 7 is realized, and finally the coolant flows out from the water outlet pipe 20, and the built-in cooler of the water tank 9 is used to cool the refluxed coolant, thereby realizing liquid cooling circulation heat dissipation; the whole liquid cooling process is simple and efficient, and can be triggered and liquid cooling heat dissipation can be performed in time when the fan needs to dissipate heat, ensuring that the bearing seat 5 can operate within the optimal operating temperature range and extend its service life. At the same time, through effective heat dissipation, the energy efficiency of the motor 2 caused by overheating can be reduced, thereby reducing the overall energy consumption. Compared with the traditional heat dissipation using natural convection, it is more efficient and faster.
