Dc cooling fan rotation speed can be with the function of temperature control, you know?
dc fan speed is refers to the number of the fan blade rotation per minute, the unit is the RPM. Fan speed by the motor coil number of turns, working voltage, the number of the fan blade, Angle and height, diameter, and bearing system common decision. Speed and quality of the fan not necessarily linked. The speed of the fan can be internal speed signal measurement, but can be by external measurements.
as the application situation and the change of environmental temperature, sometimes need different rotating speed of the fan to meet the demand. Some vendors specially designed adjustable dc fan, fan speed of the move and break up two automatically. Mainly is to let users can manually using low speed to obtain low noise in the winter, summer with high speed to obtain good heat dissipation effect.
automatic temperature radiator with a temperature sensor, according to the current working temperature automatic control fan speed, high temperature, improve the speed, low temperature, lower speed, to achieve a dynamic balance, so that the wind noise and cooling effect is to keep a better point.
the above is a cooling fan manufacturer chi small make up for the dc fan speed can share content with temperature control function, the hope can help a friend in need, if you want to learn more cooling fans products, please click: http://www. xfs— 风扇。 com/gsjj- 483. 超文本标记语言
