摘　　要：用风冷的方法给CPU降温存在着降温效率低、反应速度慢、风扇的机械转动可靠性差、噪音大等弊病。因此,这里设计了一种用半导体制冷降温的装置来提高CPU的散热效率。它用温度传感器检测电脑CPU温度,当CPU温度超过设定温度的时侯,控制电路供电使半导体制冷块制冷,使CPU温度保持恒定。为防止冷凝结露,采用绝热材料密封导热铜板及制冷块和CPU的上面,在防止冷凝露点的同时还提高了制冷的效率。The air cooling method to dissipate computer CPU is with tow efficiency, slow response speed, poor reliability of rotating fan and big noise. So, semiconductor refrigeration was designed to cool the CPU. Temperature sensor was used to test CPU＇s temperature. When CPU＇s temperature is more than the setting temperature, control circuits drive semiconductor to work for refrigeration and make the CPU＇s temperature at a constant temperature. Using thermal insulation sealing and refrigeration blocks, not only can prevent the condensation, also can improve the efficiency of the refrigeration.
