On the cooling fan of Ruifeng S3 automobile

There is a water tank and a cooling fan in the front of the car. When the vehicle stops, the cooling fan blows the wind forward to dissipate heat. The question is: 1, the vehicle is at a high speed, can the cooling fan not turn? In which direction does the air blow? 2. What does the vehicle use to judge whether the fan is rotating forward or backward? There is a water tank and a cooling fan in the front of the car. When the vehicle stops, the cooling fan blows the wind forward to dissipate heat. The question is: 1, the vehicle is at a high speed, can the cooling fan not turn? In which direction does the air blow? 2. What does the vehicle use to judge whether the fan is rotating forward or backward? Fans rotate in one direction, not two. The fan is located between the water tank and the engine. The wind direction is from the water tank to the engine through the fan. Also, the cooling mode does not mean to use the engine to cool, but the wind cools the coolant in the water tank through the mesh cooling holes of the water tank to achieve the purpose of cooling! ! Problem 1, when driving at high speed, natural wind enters the radiator network of water tank from the front of the vehicle to take away heat, and the fan generally does not turn unless the temperature is extremely high. Question 2: Does the fan rotate forward and backward? Please use ~ ~ ~ fan, which is located between the water tank and the engine. The wind direction is from the water tank to the engine through the fan. Also, the cooling method does not mean using the engine to cool, but the wind cools the coolant in the water tank through the mesh cooling holes of the water tank to achieve the purpose of cooling! ! Please accept the wind so that the car won't run at high speed with the wind. When the temperature reaches the set value, the engine temperature monitoring system indicates when the fan rotates. The fan will rotate automatically! Fans want to suck air in, so I rely on fans who don't have positive and negative turns, right? The fan that sucks air from the water tank, instead of blowing, must blow against the water tank to reduce the water temperature to about 90 degrees. When the temperature control switch works, the fan will not turn when the water temperature does not exceed 90 degrees, and the electronic fan switch will turn on as long as it is higher than 90 degrees, especially in winter. Because of the low temperature, the fan turns less, and when running at high speed, the electronic fan generally does not turn, because there is natural wind to cool down. The electronic fan is mainly controlled by the thermostat feedback to the driving computer to send instructions. In a word, the engine needs heat preservation, not just for heat dissipation. If it helps your question, please click "Adopt" on the right. First, the air from the radiator blows backwards, and then the electronic fan is automatically controlled by a water temperature sensor. I hope my answer is helpful to you. If so, please use or adopt. Thank you for blowing the fan in the direction of the engine. When it turns depends on the temperature, which is completed by the computer and the temperature sensor plug. In any direction, but the temperature does not reach a specific temperature, the electronic fan will not start. The start of the electronic fan is controlled by the thermostat @20 19.
