Cooling fan selection
1, according to the system the amount of the cooling demand and plan the number of fans are used to determine a single fan airflow working point of Q1.
2, make sure that the fan air volume point are located on the fan PQ curve 1/2 - About two-thirds to determine the shape of fan, air volume specification Q: Q1 / ( 1/2) Or Q1 / ( Eg. 。
3, fan shape is in this phase and noises in the system design specification requirements. The morning high quality cooling fan
4, when the fan selection, suggest using PWM fan speed control function, the purpose of controlling the noise, increase the life of fan, prolonged anti-dust mesh plug.
