When choosing the cooling fan for communication equipment, the manufacturer will consider the air volume, air pressure, rotating speed, etc. of the cooling fan to meet the heat dissipation needs of communication equipment, and also consider the problems of noise, protection function, etc. . The problem of reducing noise can be solved from the manufacturers of cooling fans. The manufacturers of cooling fans are required to strengthen their design capabilities and optimize the high performance, low noise of cooling fans, the solution can start from optimizing the air duct of the communication equipment system to eliminate the obstruction that blocks the inlet air of the fan. The above is the communication equipment cooling fan selection method, if you need cooling fan can know about Dongxing Yue.
