Abstract
The present invention discloses a control method for the level of noise by a rotation speed of a fan. In the method, a set temperature control figure is used for definitely predicting a rotation speed of a fan and predicting the level of noise generated by the fan and the temperature change of a central processing unit corresponding to the fan; the optimization design of the radiation effects of the fan and the level of noise is obtained, and a large amount of manpower and time used for obtaining a proper rotary speed of the fan in a previous mode of a trial and error method is reduced.
Description
Technical field
The invention relates to a kind of rotation speed of the fan controlling noise value method, particularly a kind of method of estimating the fan noise value with setting temperature control figure.
Background technology
From the Pentium Pentium epoch, the frequency of operation of central processing unit (CPU) just linearly rises, and develops into the fastest 2.5GHz now from 133MHz originally, has only experienced the time in several years.Though at present the central processing unit of main flow has all adopted the manufacturing technology of 0.18 micron even 0.13 micron, because central processing unit at a high speed is made up of many transistors, therefore, its thermal value had exceeded many than former central processing unit.Now, the above central processing unit of 1GHz has nearly all reached the above power of 40W, and the power of Pentium 4 its consumption of central processing unit that 2GHz is above is unexpectedly up to 70W, and so high consumed power directly causes the surge of central processing unit thermal value.Especially in summer, if do not take good cooling measure, can not in time a large amount of heat energy that central processing unit produced be taken away, central processing unit is inner can to produce the phenomenon of electron transfer, cause the aging even breaking-up of central processing unit, therefore, the fan that radiating effect is good, for the heat radiation of whole computing machine, be a very important key.
Yet along with the central processing unit frequency of operation constantly improves, its thermal value also increases rapidly.Therefore, many manufacturers and players are resorted to every conceivable means and are improved rotation speed of the fan or install more fan additional, wish to improve its radiating effect with the lifting of rotation speed of the fan or the increase of number of fans; But high more along with the rotating speed of fan, number of fans is many more, how therefore the increase that incident noise also can be relative, obtain an equilibrium point between the noise of the rotating speed of fan and generation, be the target of the required effort of present fan design.
Generally speaking, reduce the method for fan noise, be broadly divided into following two kinds: (1) is improved fan spindle bearing (2) and is reduced rotation speed of the fan.In first method,, fan can be divided into three types according to the fan spindle bearing classification: oiliness bearing fan, ball bearing fan and Magnetic suspension fan, the former two belongs to sliding friction and scrolling friction respectively in operation, and therefore the level of noise that is produced is bigger; Though and Magnetic suspension fan has reduced the level of noise that the bearing friction is produced, its technology is not full-fledged as yet, and cost is higher, and therefore acceptance is lower on market.
And second method-reduction rotation speed of the fan for reducing fan noise, is a kind of conspicuous method.With regard to the fan of fixed rotating speed, the level of noise that it produced is fixed, and therefore, if the consumer thinks that the level of noise that this fan produced is too big, can only change fan.And the another kind of fan that can change rotating speed, it does not have clear and definite method for the parameter setting of rotation speed of the fan control, can only be in the mode of trial and error pricing (try and error), slowly adjust the rotating speed of fan, till the level of noise that is produced is acceptable scope.Thisly finding the mode of its suitable rotating speed with trial and error pricing, need cost great amount of manpower and time, therefore, how to reduce noise with the control rotation speed of the fan, will be a very important subject under discussion.
