摘　　要：提出了一种作用于功率器件的紧凑型液冷散热器,特点为构建了一个带有旋桨式搅拌器的密封腔,能够通过电机驱动叶片搅拌冷却水形成流场以加强传热。为验证该散热器的效果,搭建了实验平台并设计了与模型外形尺寸相同的实心热沉进行对比。通过调整热源工作功率得到不同的温度-时间曲线,当热源输入功率为116 W、室温为27℃时,相比于实心热沉,使用紧凑型液冷散热器的热源温度降低8.7℃。In this paper,a water-stirring radiator is presented,which possesses a sealed chamber filled with water and a turbine.The turbine driven by a motor stirs water to cool the heat source when powered.In order to test the effect of radiator,an experimental platform was set up and a solid aluminum heat sink of the same size with the radiator was also tested as comparison.Variation of the heat source temperature with the operation time was got by varying the input power,and the advantage would reach to 8.7℃ when the input power was 116 W and the ambient temperature was27℃.
