　　The cooling fan is a very common machine in our life, and it is also widely used in automobiles. The car cooling fan is very important for the normal operation of the car, but sometimes the phenomenon of the car cooling fan does not turn, so what is the reason for the car cooling fan not turning? The following is the Taiwan fan brand to tell you .

　　1. Whether the water temperature meets the requirements: Most of today's car radiator fans use electronic temperature control to work, so generally only when the water temperature in your car reaches the required temperature, the fan will start to rotate normally. If the temperature If it is too low, the radiator fan will not turn. Therefore, when your car radiator fan fails to rotate, you should first check whether the water temperature meets the requirements.

　　2. Relay failure: If the water temperature meets the requirements and the car radiator fan still cannot work, then there may be a problem with the fan's relay. If the relay fails, the car's radiator fan will not work.

　　3.3

　　There is a problem with the temperature control switch: if there is no problem in the above two aspects, then you should check the temperature control switch. Sometimes there will be some faults in this place, which will also cause certain problems to the operation of the car radiator fan. impact, so it should also be checked.

　　The use of an independent ECU with a single chip as the carrier to control the electronic cooling fan is common in the engine cooling system and motor cooling system of large commercial vehicles. Take Yili Technology's engine intelligent cooling system ATS as an example. The cooling system is composed of multiple electronic cooling fans, and each electronic fan is controlled by a corresponding ECU. The water temperature sensor and electronic fan are connected to the ECU controller through the wiring harness, and the ECU controller is connected to the vehicle power supply and fuse box. The Yili ATS system has a fault display screen, which can automatically detect and display the system fault. If the electronic fan does not turn, the fault usually exists in two places: the ECU and the sensor. The ECU is burned (the display screen is white or black, no fault code; the ECU indicator light is not on.) The sensor is broken or the wiring harness and connector are in poor contact (fault code E2/E1). If "E1, E2" are displayed alternately, it means that there is a problem with one of the sensors, check the sensor connection harness and connectors; occasionally "E1" or "00" appears, the reason is generally poor contact of the plug-in, replace the plug-in or clean the plug-in with alcohol That's it.
