Controlling device, controlling method and computer for electrical equipment fan

Abstract

The invention provides a controlling device, a controlling method and a computer for an electrical equipment fan, the controlling device comprises a module which is used for getting generated parameters of a first pulse width modulation wave which corresponds to first temperature, the first temperature is the current temperature of an action object of a fan, the first pulse width modulation wave which corresponds to the generated parameters of the first pulse width modulation wave comprises at least two first pulses, pulse width of at least two second pulses in at least two first pulses is different; the controlling device also comprises a module which is used for generating the first pulse width modulation wave according to the generated parameters of the first pulse width modulation wave and a module which is used for sending the first pulse width modulation wave to the fan, variable-speed rotation of the fan is controlled by the module, heat dissipation requirement of the action object under the first temperature is met, and the value of hearing parameter of sound which is generated by the rotation of the fan under the control of each second pulse is different in at least two second pulses. The effect to the hearing of a user when the fan is operated is reduced by the invention.

Description

technical field [0001] The invention relates to the technical field of heat dissipation of electronic equipment, in particular to a control device, a control method and a computer for fans of electronic equipment. Background technique [0002] However, many components in electronic equipment have certain requirements on the temperature of the working environment. These components can only work normally or efficiently when the ambient temperature is lower than a certain temperature. [0003] However, in today's electronic equipment, more and more components are integrated into a limited space, and each electronic component will emit a certain amount of heat in its working state. Therefore, when the electronic equipment is working, its The temperature of the working space will be significantly higher than the outside temperature, which will cause some electronic components to not work properly and efficiently. [0004] In order to solve the above problems, the prior art adopt...

AI Technical Summary

Problems solved by technology

With the improvement of the fan structure, materials, bearings, etc., the noise of the fan has been greatly reduced. However, no matter how it is improved, the noise generated by the fan is still high when it is running at high speed, which greatly affects the User's experience of using electronic equipment
