摘要
本文主要介绍智能风机的优点和工作方式,结合目前较为流行的几类产品,介绍了智能风机的工作原理和工作特性。对分档式转速和连续可调式转速风机的工作方式进行了介绍。在实际使用时,可参照本文选择合适的形式,以适应不同的系统及散热条件。本文介绍的控制电路均为模拟器件组成,也可采用数字芯片来代替控制部分,但控制转速的方式均为采用PWM技术调整端电压,从而达到控制风机转速的目的。
This paper introduces the great points and the operation modes of smart fan. With some kinds of popular products, this text tells us the principle and operates of intelligent fan. Introduced section speed and continuous speed fansprinciple. In reality use, you can choice one kind of the fans, in order to suite your system and blow your heat away. Fans in this text introduced, is analogue circle. You can use digital circle instead. Speed control tech- nique is use the PWM to set the voltage of the fan.
