Silicone Fans and Electronic Fans

About the difference between silicone oil fan and electronic fan:
1. Different power sources. Silicone oil fan power source is the engine, electronic fan power source is a separate electric motor.
2. The engine temperature sensing device is different. The engine is through the silicone oil as a medium to the silicone oil fan transmission torque, silicone oil at different temperatures in different viscosities, the engine utilizes the characteristics of the silicone oil to identify the engine temperature. Electronic fan through the thermostat feel the engine water temperature temperature, so as to adjust the electronic fan motor switch.
3. Different heat dissipation ability at low speed. Silicone oil fan power from the engine, and with the engine temperature changes. When the engine is at low speed, the speed of the silicone oil fan is extremely low, at this time the engine fan heat capacity is extremely low. An electronic fan does not vary with the engine and always maintains the engine temperature at a reasonable temperature.
For example, many of Toyota's vehicle models use silicone oil fans, and it's really not that hard to understand. This is because almost all of these Toyota models are powered by small-displacement, low-power naturally aspirated engines. This type of engine itself does not generate high temperatures, so the engine cooling requirements are not high, if the vehicle in the test shows that the silicone oil fan has been able to meet the engine cooling needs, the use of silicone oil fan is not wrong. Secondly, the price of silicone fans is generally lower, saving costs.
