How to measure the quality of a ventilation fan


to measure the quality of a heat dissipation, the two most important aspects of performance and life, the second is more and more attention to the work of the noise, moreover relates to can be normal use, also must pay attention to the specifications and power of the fan. With the related data for wind area (bottom size Fan at the bottom of the casing outside the area of minus and motor portion of the results of the area) , and further affect the fan is the important performance index of the airflow, have greater air volume can be reduced wind speed does not reduce the air volume, using 'large-diameter fan' was one of the developing trend of the cooling fan, increase the height of the fan is beneficial to increase the fan power, increase leaf area, and can enhance the performance of the fan, the fan will be used to increase height adding deflector on outer box or change the blade rotation direction ( The axial flow fan) And so on.
