    Resolve to reduce Waterproof Cooling Fan noise method

    Date: 2014-11-8   Click: 1475 Times

    1, "Waterproof Cooling Fan" system impedance: Range between the air inlet and a housing outlet of the total system impedance of 60-80%, while the greater airflow, noise is relatively higher. System impedance is higher, the greater airflow required for cooling, so in order to minimize the noise, the system impedance must be minimized.
    2, disrupt airflow: spoiler along obstruct airflow path encountered caused generate noise. Therefore any obstacles, particularly in the critical range of air inlet and outlet must be avoided in order to reduce noise.
    3, "Waterproof 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 of the fan at the same air volume delivery.
    4, temperature rise: in a system, the temperature rise is inversely proportional to the amount of air required for cooling allowed. Allowable temperature rise slightly increased, to a significant reduction in the required amount of wind. Therefore, if allowed to impose the temperature slightly relax some restrictions, will reduce the required amount of wind noise can also be reduced.
    5. Vibration: some cases, very light weight of the entire system, or the system must operate in accordance with the provisions when some particularly soft isolated equipment is recommended in order to avoid passing the fan vibration.
    6, the voltage variation: variation in voltage will affect the noise level. The higher the voltage applied to the fan, because the speed increases, the greater the vibration, noise generation is also greater.
    7, "Waterproof Cooling Fan" Design considerations: each part design constitutes the fan will affect the noise levels. Consider the following design can be reached to reduce noise: the winding core size, blades and frame design and precision manufacturing and balance.
