1, the turbofan can output more air volume in a smaller space occupation, and improve the heat dissipation effect.
2. The machining accuracy of turbine fan blades is higher than that of ordinary cooling fans, and the noise generated by dusty impeller or high-speed operation is also greater.
3. With the reduction of CPU power consumption, the CPU turbofan is gradually replaced by a large-caliber low-speed ordinary axial-flow silent fan, but it is still often used in high-performance graphics cards, especially in the radiator of public graphics cards.
4. The turbine fan is driven by the motor to rotate the impeller, and the blades in the impeller force the gas to rotate, thus doing work on the gas and increasing its momentum. Under the action of centrifugal force, gas is thrown around the impeller, and kinetic energy is converted into pressure energy through the volute. When the gas in the impeller is exhausted, the pressure in the impeller is lower than that in the intake pipe. Under the action of pressure difference, new gas is sucked into the impeller, and the gas is continuously exhausted from the fan.
