风扇安装在发动机与散热器之间。风扇叶片由发动机驱动旋转时，产生高速气流，带走散热器中冷却液的热量，达到给发动机散热的目的。
但是，风扇的转速与发动机在各种工况下运行有很大关系。当发动机转速较慢时，不容易得到足够快的风扇转速；而当发动机转速较高，即汽车在高速行驶时，或者在天气寒冷时，则不希望风扇的转速过高，以免增压发动机的功率损失和风扇噪声。所以在现在汽车中，常常采用各种措施来控制风扇的转速。这些措施包括采用硅油离合器、电动风扇和电控液压驱动式风扇。

The fan is installed between the engine and the radiator. When the fan blades are driven to rotate by the engine, high-speed airflow is generated, which takes away the heat of the coolant in the radiator and achieves the purpose of dissipating heat from the engine.However, the speed of the fan is closely related to the operation of the engine under various working conditions. When the engine speed is slow, it is not easy to obtain a sufficiently fast fan speed; When the engine speed is high, that is, when the car is driving at high speeds or in cold weather, it is not desirable for the fan speed to be too high to avoid power loss and fan noise from the turbocharged engine. So in modern cars, various measures are often taken to control the speed of the fan. These measures include the use of silicone oil clutches, electric fans, and electrically controlled hydraulic driven fans.Disclaimer | Some content is sourced from the internet!
