Matters needing attention when choosing a cooling fan for communication equipment

by:TOCH     2021-03-26

When we select a cooling fan for communication equipment, in addition to focusing on whether the air volume of the cooling fan can meet the cooling requirements of the equipment, we also need to pay attention to the noise problem. The reasons for the noise of the cooling fan are generally attributed to two points: one is generated by cutting air when the fan blades rotate, which is called discrete noise; the other is generated when the airflow generated by the cooling fan runs against obstacles, which is called broadband noise. If communication equipment has relatively high requirements for noise, it is necessary to start with the above two reasons to reduce noise to the greatest extent. For the noise generated by fan blade rotation, the solution can start with the cooling fan manufacturer, requiring the cooling fan manufacturer to strengthen its design capabilities and continuously optimize the design of high-performance and low-noise airfoils; or to evaluate the accurate system characteristics in the early stage and supply the fan. With the cooperation of the supplier, choose the cooling fan in the high-efficiency working range in the system. For reducing broadband noise, the solution can start with optimizing the air duct of the communication equipment system and removing as much as possible the obstacles that block the fan from entering the air. Human wisdom is endless. Noise reduction cabinets and sound-absorbing materials are also applied to noise reduction to minimize noise.
