DC FAN is no stranger to many people nowadays. In our daily life, we often come into contact with many customers when choosing DC aircraft The first thing to consider is to ask DC FAN manufacturers quality, product quality, product specifications, as well as DC fan performance, these are each customer select DC fan requirements. But what are the factors that harm the speed ratio of DC fan? DC Fan speed can be divided into two types of ultra-strong and noise reduction. The difference between ultra-strong type and noise reduction type is not too harsh, but for the same specifications, the same operating voltage fan, speed and noise is always irreconcilable 2 contradictions. The speed of the fan is the number of revolutions per minute of the fan blades. The company is RPM. The rotation speed of DC FAN is determined by the number of coils, working voltage, the number of fan blades, obliquity, height, straight warp and fan roller bearing system. When the structure of the fan is fixed, the speed of the fan using AC current changes with the change of the operating voltage. The speed of the fan can be accurately measured according to the internal speed network signal and the external speed network signal. There is no necessary relationship between the rotational speed of DC fans and the professional ability of heat dissipation. A higher rotational speed of the fans will cause higher noise. If the air volume of the fans is similar, you can choose a fan with lower rotational speed There's no big noise when you use it.
