Embodiment Construction

[0023] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.

[0024] The invention provides a fan speed regulating device, which includes a level conversion unit for level conversion of an input control signal, a switch control unit for controlling the fan power supply itself to be turned on and off according to the signal output by the level conversion unit, and the switch control unit Connected in series to the fan power supply. The fan speed control signal is input to the level conversion unit, and the level conversion unit adjusts the level of the control signal and then inputs it to the switch control unit. The switch control unit continuously controls the power supply of the fan according to the control signal to achieve the purpose of controlling the fan...

Abstract

A device and a method of fan speed regulation comprise: an electrical level conversion unit used for carrying out electrical level conversion on an input control signal, and a switch control unit used for controlling the power of the fan to switch-on or break according to the signal outputted by the electrical level conversion unit. The device and method are easy to realize, with low power consumption and low cost, and can achieve multiple rotating speed gears which can accurately regulate the speed and obtain good effect according to need.

Description

technical field [0001] The invention relates to a fan speed regulating device and method. Background technique [0002] At present, the integration of single boards in the communication field is getting higher and higher, and the system equipment is getting smaller and smaller. Especially when the single board works at high power, the problem of heat dissipation in the equipment becomes relatively prominent. Solve the problem of equipment There are many ways to solve the heat dissipation problem, among which fans have been widely used as an effective heat dissipation tool. Although the higher the wind speed of the fan, the stronger the heat dissipation effect, but the high wind speed also increases the noise power of the fan, a strong noise source, exponentially, and increases the power consumption of the system, and the long-term operation of the fan at full speed will also reduce the service life. , so how to adjust the fan speed easily and effectively has become an impor...
