Performance calculation of silicone oil fan clutch

This paper established the torque model of the cylinder head and end faceof the siliconeoil fan clutch under cylindrical coordinates. First, some correlation coefficients were determined based on the data of the corresponding device provided by the supplier, and then the model was used to directly obtain the performance curve of the fan at different inputs, speed and radiator outlet temperature conditions.The performance curves of the LE-040-Z670H-9 and LB-15.9X44-Z410W-7 silicone oil fan clutches are in line with the actual conditions, indicating that the established clutch mathematical model is correct and which provides theoretical support for designing the improved clutch.
