Micro Cooling Fan how to achieve low noise

Time:2014-12-12 Click:514Times

1. "Micro Cooling Fan" system impedance
Range between a housing of the air inlet and outlet of the total system impedance of 60 to 80%, while the greater the airflow, the noise is relatively higher. System impedance is higher, the greater the airflow required for cooling, so in order to minimize the noise, the system impedance must be minimized.
2. disrupt airflow
Spoiler obstruct airflow path along the encounter caused generate noise. Therefore any obstacles, particularly in the critical range of the air inlet and outlet must be avoided in order to reduce noise.
3. "Micro Cooling Fan" speed and size
Due to the high speed fan noise greater than the low speed fan, so you should try and use low-speed fans as possible. And a large size, low speed fan, generally, quieter than the small size, high speed fan when transporting the same air volume.
4. Temperature rise
In one system, the desired cooling air flow is inversely proportional to the allowable temperature rise. Allowable temperature rise slightly increased, to a significant reduction in the required amount of wind. Therefore, if allowed to impose the limit temperature rise slightly relax, will reduce the required amount of wind noise can be reduced.
5. Vibration
Some cases, the weight of the entire system is very light, or the system must operate in accordance with the provisions when some particularly soft isolated equipment recommended in order to avoid passing the fan vibration.
6. "Micro Cooling Fan" voltage fluctuation
Voltage fluctuations will affect the noise level. The higher the voltage applied to the fan, because the speed increases, the greater the vibration, noise generated is also greater.
