摘要
通过数值模拟研究了交错式微针鳍散热器的散热效应,分析了针鳍阵列间距和高度对散热器壁温和压降的影响。结果表明,压降随针鳍间距和针鳍高度的减小而呈非线性增加;壁温随针鳍间距的增大而上升,随针鳍高度的增加则呈现出波动趋势。基于上述研究,进一步利用响应表面近似法对微针鳍的横向间距、纵向间距和高度进行了优化,优化后压降最大可降低61.11%。
Abstract
The heat dissipation effect of the interleaved micropinfin heat sink was studied by numerical simulation, and the influence of the array spacing and height of the pin fins on the wall temperature and pressure drop of the heat sink was studied. Experimental results indicate that the press drop increases nonlinearly with the decreasing array spacing and height of the pin fins, while the wall temperature increases with the increase of the pin fin spacing, but it shows a fluctuation trend with the increase of the pin fin height. Based on the above research, it further optimizes the lateral spacing, longitudinal spacing and height of the microneedle fins with the method of response surface approximation. The pressure drop can be reduced by a maximum of 61.11% after optimization.
