| 摘 要： | 针对高热流密度器件的散热问题，设计了有扰流微细槽道散热器。采用去离子水为工作介质，对其内流动和换热特性进行实验研究，结果表明：流体流过槽道时单位长度压降与雷诺数成正比，扰流对槽道内压降特性影响较小；存在最佳的雷诺数使有无扰流情况下槽道内换热努谢尔特数差别最大，并拟合了不同情况下努谢尔特数和雷诺数的关系式；采用进口段无量纲加热长度分析发现，扰流导致流体的热进口段长度增加；分析压降和进口热阻特性可以发现，在槽道长度一定时存在最佳流速使带扰流的微槽道的性能最佳。

| Abstract: | The mini-channel cooling system with cylinder disturbed flow is proposed for high-power laser cooling.Using deionized-water as working fluid,heat transfer and pressure drop characters of mini-channel heat radiators with and without disturbed flow are experimentally studied.It is found that the pressure drop per unit length is proportional to Reynolds number,and the disturbed flow has the slight effect on pressure drop.There is an optimal Reynolds number at which the difference of transfer performance betwee... |
