Micro Cooling Fan Power study mode

Time:2014-11-30 Click:476Times

"Micro Cooling Fan" input power can be divided into useful power and unwanted power in two parts. Useful power that ultimately drive the blades rotating power, called the input shaft work; useless power resistive losses include components, mechanical friction loss and vibration wear and tear. The ratio of useful power and total power consumption, i.e., "Micro Cooling Fan" energy conversion efficiency, is naturally the higher the better. In addition to the fan energy conversion efficiency, there is an important class of fan efficiency, i.e., the input shaft power is converted to fluid (air) kinetic energy efficiency. Common "Micro Cooling Fan" There are three kinds examine ways:
Total pressure efficiency = total pressure flow power output / input shaft power x 100%;
HIP HIP flow efficiency = output power / input shaft power x 100%;
Hydraulic efficiency = actual full head / Ideal full head x 100%;
