摘要
针对传统蛇形通道散热器温度高以及温差大的问题,设计了一种螺旋形通道,建立了仿真模型,对比了传统蛇形通道和螺旋形通道的性能。对螺旋形通道进行了改进,研究了通道入口宽度、通道出口宽度、通道转角圆半径对螺旋形通道的传热和压降特性的影响,利用NSAG-Ⅱ算法对螺旋通道的尺寸参数进行了多目标优化,得出了最优解集。仿真结果表明,螺旋形通道与蛇形通道相比,出入口压降下降了0.2%,最高温度下降了18℃,温差下降了23.5℃;多目标优化后的最高温度下降了20.07℃。
To address the issues of high temperature and large temperature difference in traditional serpentine flow channels radiator,a spiral flow channel heat dissipation is designed.A simulation model is established to compare the performance of traditional serpentine flow channels and spiral flow channels.Improvements are made to the spiral channel,studying the effects of inlet channel width,outlet channel width,and channel fillet on the heat transfer and pressure drop characteristics of the spiral channel.The NSAGⅡalgorithm is used to multi-objective optimize the size parameters of the spiral channel and obtain the optimal solution set.The simulation results show that compared with the serpentine channel,the inlet and outlet pressure drop decreases by 0.2%,the maximum temperature decreases by 18℃,and the temperature difference decreases by 23.5℃;The maximum temperature of the optimized optimal solution decreases by 20.07℃.
