摘要
针对一种基于扰流作用的多层蜂窝形微通道热沉结构设计,在不同流量、不同加热功率、不同热沉设计尺寸等实验条件下对其进行了散热测试实验,对影响该系统性能的因素进行了分析和讨论。散热实验结果显示在热沉进出口管径采用外径为6mm,内径为4mm不锈钢毛细管时,其有效散热热流密度可达18.2W/cm2,基板温度为48.3℃,微泵耗功为2.4W,具有良好的换热效果。
Experimental investigation was conducted to determine the heat transfer characteristics and cooling performance of a multilayered honeycomb microchannel heatsink design based on the flow disruption.The influences of different flow rate,different input heating power and various heatsink structure dimensions on the system cooling performance were discussed and analyzed experimentally.The results demonstrated that the heatsink cooling system with the in/outlet inner diameter ofφ4mm design could effectively remove the heat flux of 18.2W/cm2 under 2.4Wpumping power,while the junction-wall temperature was 48.3℃.The experimental results show that the present cooing system had good performance.
