摘要/Abstract

摘要： 以换热量最大为目标进行液冷通道分布优化设计，构建拓扑优化设计数学模型，采用霍尔姆兹偏微分方程形式的密度过滤避免拓扑形态出现棋盘格现象；同时，采用双曲正切投影方法以得到清晰的流体通道拓扑形态。对不同进出口布置的典型算例进行优化设计，设计结果与传统直通道比较，通过有限元数值模拟，以最高温度为评价指标，对比各进出口布置的拓扑优化通道与传统直通道的散热性能。仿真结果表明，拓扑优化通道比直通道的最高温度低，且采用垂直对角出入口布置散热性能最佳。进一步制作液冷板，通过试验验证了设计方法的有效性及数值模拟的准确性。

Abstract: In order to achieve an optimal thermal performance of the liquid-cooled heat sink, the cooling channel layout designed by topology optimization is studied based on the heat exchange maximization problem. In the optimization stage, the Helmholtz filtering is employed to eliminate the numerical instability, and a hyperbolic tangent projection is used to obtain a clear configuration. Then three design cases with different inlet and outlet layouts are studied, and the conventional straight cooling channel is introduced as a reference case to compare the thermal performances with the optimized channel layouts. The results show that the topology optimized channel layout can provide a lower peat temperature compared with the straight channel layout, and the orthogonal diagonal inlet-outlet layout keeps the peak temperature to a minimum among three competitive inlet-outlet layout designs. Finally, the flow and thermal performances of the heat sinks are investigated experimentally. The experimental results show a good correspondence with the numerical results. Hence, the effectiveness of the proposed design method is validated.

Key words: experimental investigation, heat exchange maximization, liquid-cooled heat sink, numerical modeling, topology optimization
