"Micro Cooling Fan" Manufacturers of 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 what is it short pressure: pressure is the pressure of the wind the plane perpendicular to the direction of airflow suffered. Pressure (wind pressure) due to the blocking of the building, so that the ambient air is blocked, the dynamic pressure drop, and side and back of the static pressure increase local vortices generate static pressure drop and distant disturbed airflow, this kind of "Micro Cooling Fan "static collectively referred to as the raising and lowering pressure
