| 摘 要： | 高速芯片作为仪器仪表系统的主要功率元件,工作时通常会产生热量。为避免芯片温度过高导致其性能恶化,需要对芯片采取冷却。通过温度传感器集成电路测量高速芯片温度并智能调节风扇转速,采用PWM技术驱动风扇,并设计合理的风扇电源供电方案,在温度较低时可最大限度降低风扇转速和噪声水平。

| Abstract: | As an important part of instrument system, high--speed chips are easy to get hot when work- ing. In order to avoid its performance get worse, taking some cooling techniques is necessary. The tem- perature sensor integrated circuit can examine the temperature of high--speed chips and intelligently control the speed of cooling fans. The cooling fan can run slowly by powering the fan with PWM tech-nique and designing the reasonable power circuit. |
