Bimetallic temperature sensing clutch technology "Waterproof Cooling Fan" principle is the thermal signal transfer process. The cooling liquid passes through the radiator, and the air flow flowing through the radiator for heat exchange. Bimetal temperature sensitive clutch feel after the front end of the airst ream temperature, generation of deformation, and drives the clutch inner valve to open or close the clutch, so as to control "Waterproof Cooling Fan" speed purposes. Through the above description contrast to believe that you have understood the importance of small cooling fan, electronic silicone clutch is mainly used in the Euro III emission and above-grade large passenger cars, trucks and parts of construction machinery vehicles, can effectively reduce fuel consumption and reduce engine load and thus reduce emissions emissions. This is our moment to meet State IV emission requirements. I believe that with escalating emissions requirements and increasingly stringent technology, Borg Warner advanced electronic control silicone "Waterproof Cooling Fan" will be generalizable.
