Silicon Viscous Oil Cooling 1308X13H08 010 A CAMC Truck Engine Fan

Silicon oil visco fan clutch replaces 1308X13H08-010-A for CAMC Truck Engine Cooling Part ZIQUN brand

Silicone oil---The degree of expansion is different depending on the temperature. When the temperature is high, the expansion degree is large, and the fan speed is large; when the temperature is low, the expansion degree is small, and the fan speed is low or closed.

The viscous silicone oil flows into the gap between the driving plate and the driven plate and the driving plate and the clutch housing, and transmits the torque on the driving plate to the clutch housing, driving the fan to rotate at a high speed, and the clutch is now in the engaged state.
When the temperature of the airflow blowing to the bimetallic temperature sensor is lower than 35℃ due to the load drop of the engine, the control valve plate closes the oil inlet A, and the silicone oil no longer enters the working cavity, but the original silicone oil in the working cavity It continues to return to the oil storage chamber under the action of centrifugal force until it is emptied.

When the engine load increases and the coolant temperature increases, the temperature of the airflow through the radiator core also increases.
The high-temperature air flow blows on the bimetallic temperature sensor, which causes the bimetallic plate to be heated and deformed, and drives the valve plate drive pin and the control valve plate to deflect to an angle.
After the airflow temperature exceeds 65°C, the oil inlet hole A on the driven plate is opened, and the silicone oil in the oil storage cavity enters the working cavity through this hole.

When the car is driving, due to changes in environmental conditions and operating conditions, the thermal condition of the engine is also changing. Therefore, the cooling intensity of the engine must be adjusted at any time. For example, in the hot summer, when the engine works at low speed and heavy load, and the temperature of the coolant is high, the fan should rotate at high speed to increase the cooling air volume and enhance the heat dissipation of the radiator.
