What is the type of the axial flow fan
In the purchase of axial flow fan is the first to consider the quality of the wind turbine manufacturers, product quality, product size, and finally there is the product has a cooling performance, these can be the source of wind can do for you.
However, what are the decisive factors for the rotation speed of the axial fan?
The axial flow fan speed can be divided into two types: strong and silent type.
The distinction between the strong and silent type is not too strict, but for the same size, the same voltage of the computer fan, the wind pressure and noise will never be reconciled with the two contradictions. The speed of the fan is the number of times per minute, the unit is rpm. The cooling fan speed is determined by the number of turns, working voltage, number of fan pages, angle, height, diameter and fan bearing system.In the case of a fan structure, the speed of the DC fan (i.e., the fan of the DC electric fan) is changed with the change of working voltage.The speed of the fan can be measured by the internal speed signal can also be measured by the external measurement is a special red line speed measurement of the fan speed, internal measurement can be directly to the BIOS, it can be seen through software. Internal measurement is relatively large.
Axial fan speed and heat dissipation capacity is not necessarily the relationship, the higher the speed of the fan will bring a higher noise, the choice of cooling fan products if the wind is almost, you can choose a low speed fan, the use will be quiet.
