Micro Cooling Fan pressure is how did this happen?

   "Micro Cooling Fan" manufacturers increasing competition, with the continuous development of technology, the fan technology and design concepts are constantly innovating, but no matter how technology further improve the fan pressure principle is not going to change." ? "Micro Cooling Fan" of pressure refers to pressure what is it short: pressure is the pressure of the wind the plane perpendicular to the direction of airflow suffered. Pressure Because the building block that ambient air is blocked, the dynamic pressure drop, "Micro Cooling Fan" static pressure increases and side and rear produce local vortex airflow static pressure drop and distant disturbed, this kind of static pressure collectively referred to as the raising and lowering pressure.
