SuKoTec Product Knowledge - Working Principles of Automotive Electronic Fans

The function of an automotive electronic fan is to dissipate heat from the engine and assist in cooling the engine. The electronic fan is controlled by the engine coolant temperature switch to operate, usually with two levels of speed: 90 ° C, one level of low speed: 95 ° C, and two levels of high speed: 95 ° C. In addition, opening the air conditioner will also control the operation of the electronic fan (condenser temperature and refrigerant pressure control). Therefore, the electronic fan is an important cooling component in the air conditioning system.

Common troubleshooting methods for electronic fans

Common faults:

(1) The electronic fan does not rotate or cannot operate at high speed, and the air conditioning cannot operate normally.

(2) The electronic fan has abnormal noise and loud noise.

Solution

(1) You can use an engine diagnostic tool to test the function of the electronic fan. If the fan can rotate normally, then the circuit is normal. Check whether the thermostat is normal.

(2) High engine water temperature is mostly caused by the failure of the electronic fan to start. After troubleshooting the electronic fan, the water temperature will return to normal levels. If the electronic fan does not work, first check for poor connections at the connector. Check the power and grounding of the electronic fan, check if the fan is stuck, and if the fan motor is burnt out.

(3) Check if there are scratches on the fan casing. Check for signs of fan blade deformation, bearing damage, or foreign objects entering the fan.

SuKoTec electronic fan product advantages:

Durability and product performance

The high-quality fan assembly and fan components ensure cooling performance and stable and long-lasting operation;

Innovative technology effectively resists mechanical damage and wear and tear

The raw materials match 100% with the original parts. Select high-quality plastics, eliminate recycled plastics, and use high-temperature resistant, low warping, and shock absorbing materials to minimize deformation and ensure smooth motor operation under high temperatures.

Smooth operation of the motor

High quality motor armature can ensure reliable operation of the motor, while also providing strong protection against current peaks and overvoltage protection.

Anti-corrosion process

Strictly follow REACH regulations to carry out special anti-corrosion treatment on the motor cover to avoid electromagnetic interference with other electronic components.
