220V Cooling Fan is designed by improving the speed

Relationship between pressure and air flow is relative, at the same speed, "220V Cooling Fan" the greater the pressure, then it's the smaller air volume, and vice versa. If you want to simultaneously increase the fan air volume and pressure, then in addition to the blade design, by increasing the speed of the method it is relatively simple. However, the ensuing sound of blades of wind shear and friction bearings under high speed rotation sound and other noise problems are troublesome people. "220V Cooling Fan" of wind pressure and wind volume has been relatively easy to confuse the concept of many players, the simple, the pressure is the pressure of the wind, the greater the pressure, the greater the power of the wind, the more likely the chassis punching , air filter and other parts blown through. The wind can be understood as the same time by "220V Cooling Fan" air traffic volume at the same time, we can exchange more airflow to enhance heat dissipation.
