What is the working principle of a silicone oil clutch fan?
1 Answers
The working principle of a silicone oil clutch fan: This type of clutch uses silicone oil as the medium. When the temperature is low, the silicone oil does not flow, and the fan clutch disengages. When the temperature is high, the viscosity of the silicone oil causes the fan clutch to engage, allowing the fan to rotate. Silicone oil fan clutches are not commonly found in general household vehicles but are more frequently seen in large trucks and heavy-duty vehicles. In household cars, the cooling fans are electronically controlled, with temperature sensors in the engine. When the engine coolant temperature is too high, the cooling fan automatically turns on; when the temperature is too low, the fan shuts off. The silicone oil fan clutch uses silicone oil as the medium, utilizing the shear viscosity of the silicone oil to transmit torque.
