• A cooling fan is an essential component of a vehicles cooling system. It is responsible for cooling the engine by drawing in air through the radiator and then expelling it out into the engine compartment.
• The cooling fan helps to regulate the temperature of the engine and prevent it from overheating, which can cause serious damage to the engine and other components.

The cooling fan can also improve vehicle performance and fuel efficiency. When the engine is running at high temperatures, it can cause it to run less efficiently, leading to reduced power and increased fuel consumption. By keeping the engine at an optimal temperature, the cooling fan helps maintain the vehicles performance and fuel efficiency.

• High Thermal Conductivity: The materials used in cooling fans should have high thermal conductivity to efficiently transfer heat away from the device.
• Low Friction: Materials with low friction are preferred for fan blades to reduce the amount of energy needed to rotate the blades.
• Durable: Cooling fans need to be durable to withstand the wear and tear of continuous use.
