What is the role of car electronic fan
The main role of automotive electronic fan is to assist the engine to heat and cool . It enhances the heat dissipation effect by improving the air flow speed of the radiator core, thereby speeding up the cooling speed of the water and achieving the goal of temperature reduction . Specifically, the electronic fan cools the engine block and transmission, and at the same time provides heat dissipation to the air conditioning condenser, ensuring that the engine and other components operate within the appropriate temperature range, thereby extending their service life .
Working principle
The working principle of the automobile electronic fan is based on the control of the temperature controller. When the engine coolant temperature rises to the set upper limit value, the thermostat is switched on and the fan starts to work; When the coolant temperature decreases to the set lower limit value, the thermostat turns off the power and the fan stops working . In addition, electronic fans usually have two levels of speed, starting at 90°C and 95°C, the former for low speed and the latter for high speed. When the automobile air conditioner is turned on, the operation of the electronic fan is also controlled by the temperature of the condenser and the pressure of the refrigerant .
Type and design
There are many types of automotive electronic fans, the common silicone oil clutch cooling fan and electromagnetic clutch cooling fan. The advantage of these types of fans is that they only start when the engine needs to be cooled down, thus minimizing energy loss to the engine . The fan is usually installed at the rear of the tank, near the engine compartment side, and its function is to draw wind from the front of the tank when it is turned on.
Automotive electronic fan is an electrically controlled radiator fan, mainly used in the cooling system of automobiles. It controls the operation of the fan through electrical signals to ensure that the engine can maintain the appropriate temperature under various working conditions. The working principle of the electronic fan is based on the detection of the temperature sensor or water temperature sensor, when the engine is detected to be overheated, the sensor will send a signal to the computer, and the computer will issue a command to start the electronic fan, thereby helping the radiator to dissipate heat.
The main components of an electronic fan include a motor, an impeller and a control unit. The combination of the motor and impeller generates the air flow, while the control unit interprets the signal and controls the movement of the electronic fan. Electronic fans are usually connected using electrical connectors, and their power source can be direct current or alternating current.
Compared to traditional fans, automotive electronic fans have higher efficiency because it is able to precisely control the fan speed through the computer, matching the state of the radiator. However, electronic fans also require highly accurate computer and circuit support, and once the electronic system fails, the entire fan system will not work. In addition, the price of electronic fans is usually higher than that of traditional fans.
In order to ensure the normal operation of the electronic fan, regular maintenance and inspection are necessary. Common problems include insufficient motor lubrication, overheating, starting capacitance problems, and motor bushing wear, which can affect the fan speed or cause the fan to stop working. Therefore, timely investigation and resolution of these problems is essential to maintain the best working condition of the engine.
