[0002] In order to further save energy for the engine and improve engine efficiency, the heat dissipation of the car radiator has changed from the traditional first-generation cooling fan connected to the engine, and the fan will run and consume energy as long as the engine starts, and gradually developed to the second generation. Silicon oil clutch is installed before the cooling fan heats up. , using the principle of thermal expansion and contraction of silicone oil, the fan does not run at low temperature, and starts to run and dissipate heat when the water temperature of the water tank rises to a predetermined temperature, which achieves a certain energy-saving effect. However, due to the silicone oil clutch, there are disadvantages such as low temperature control accuracy and easy oil leakage. At present, the third generation is gradually developing an electromagnetic fan clutch in front of the cooling fan, using a temperature control switch and a controller to control the operation of the fan. The disadvantages are that the fan is noisy and the heat dissipation effect is poor when running at low speed in summer.

Now the fourth-generation electronic fan has appeared, which uses four motors, four cooling fans are installed on the four motors, and the controller is used to control the operation and stop of the four fans according to the height of the user to achieve the effect of heat dissipation and energy saving. The advantage is only Trial for new cars, the speed is not affected by the change of engine speed, the disadvantage is that the power consumption is large, the current of the four fan motors is 50-70A, the cost is high, when the old car is refitted due to the large power consumption, it is necessary to replace a larger battery and generator
