Population continues to increase, the demand for cars is also more and more big, automotive electrical requirements also more up, electronic fan is a necessary equipment, car for automotive electronic fan to know a lot of people just stop at the fan this concept, automobile electronic fan is how to work?

The working process of the automobile electronic fan: automotive electronic fan is controlled by a thermostat, when the water temperature rise is the highest limit thermostat, turning on the power supply fan start working, turn off the power supply to stay under the water temperature drops to limit the thermostat, fan to stop working. The signal is transmitted to the electronic fan control unit by the thermal switch to control the electronic fan starting at different speeds. Automobile electronic fan is controlled by the engine coolant temperature switch it work, usually have two levels of secondary high-speed rotational speed 90 ℃ level at 95 ℃. In addition, the air-conditioning can also control the electronic fan operation (condenser temperature and refrigerant pressure control).
