parallel fan: "Mini Air Cooling Fan" parallel dual fan pressure unchanged, but will increase the amount of wind. Therefore increase the amount of wind to increase the cooling effect, in the design of power if the heat is too small, you can consider increasing the fan to resolve.the series fan: Results of the series fan is pressure to increase, but the wind changed. This approach is not to solve the heat problem, generally used in the past when much wind resistance adopted to ensure that the amount of wind. "Mini Air Cooling Fan" major issues. Using the process in order to reduce the low-noise must note the following:System Impedance: Air flow resistance will cause air flow noise generation.Airflow turbulence: due to poor design of the flow channel of air turbulence caused by high-frequency noise will appear, if it does not improve the flow channel is difficult to have a qualitative improvement.
"Mini Air Cooling Fan" fan speed and size: the cooling effect of the fan speed, the faster the better, the greater the larger the size of the fan air flow, cooling effect is better. Fans of turn.The higher the speed the greater the noise, the larger the size the larger the noise.Temperature rise: after reducing the temperature difference between the temperature rise, the cooling effect is reduced.
Vibration: vibration will cause the fan noise increased, reducing life expectancy as well as the speed is reduced.
