Matters should be paid attention to when choose communication equipment cooling fans
release date: 2016 - 06 - 09
we are to choose a cooling fan to communications equipment, in addition to focus on a cooling fan air volume can meet the cooling requirements of the device, also need to pay attention to the point that the noise problem.
the reason of the cooling fan noise usually boils down to two things: one is the fan blades rotating cutting air, called discrete noise; Second is that, when cooling fan running airflow produced by the collision obstacles and called broadband noise.
if communication equipment is high to the requirement of noise, you need to, from the perspective of the above two reasons, the maximum extent to reduce noise. For noise produced by the rotation of blades, the solution can, from the perspective of the cooling fan manufacturers, requires a cooling fan manufacturer strengthening design capability, continuous optimization design of high performance, low noise airfoils; Or the previous evaluation system characteristics accurately, and fan suppliers, choose in the system and high efficient work range of cooling fans. For broadband noise reduction, the solution can optimize communications equipment system air duct, eliminate obstacles in aspects of keep out fan ventilation.
human wisdom is infinite, noise control cabinet, sound-absorbing materials are applied to noise reduction, maximum limit to reduce noise.
