If you take into account the "24V DC Cooling Fan" outlet different wind speeds at various points, will have to variable V, S for the micro-yuan, according to 1/2 x S x ρ x V ^ 3 formula to calculate the surface integral on the outlet plane , analysis is more complicated, will not be discussed here in detail. As long as the magnitude of the relationship between the fan power and wind speed, wind somewhat understand the above formula, it served its purpose. "24V DC Cooling Fan" After the design is determined, total pressure efficiency determine if the energy conversion efficiency is constant, can be seen from the above equation: fixed area after the wind power and wind speed (wind) to the third power of synchronous growth; the same amount of wind fan, the larger the area of wind power is smaller. Therefore, "24V DC Cooling Fan" depends primarily on the amount of wind power and size specifications. With the amount of wind power will (wind speed) increases sharply increased, increasing the caliber it will help to control the power.
