Gyroid型TPMS结构非均匀填充的主动冷却结构性能分析OA

This article studies the performance improvement design problem of active cooling structures with filled Gyroid-type triply periodic minimal surface structures(TPMS),and discusses the influence of non-uniform distribution of configuration description parameters(shape description parameters and thickness)of TPMS structures on the cooling performance.Specifically,through numerical simulation of the active cooling structure with four cells filled,the influence of different distributions of descriptive parameters such as thickness and shape of the TPMS structure on cooling performance is analyzed.Firstly,by analyzing the cooling performance of uniformly filled TPMS structures with different thicknesses,it was verified that the thickness of TPMS is positively correlated with the cooling performance.Then,using the orthogonal experimental method,the cooling performance of 39 gradient-filled TPMS cooling structures with different shape parameter C distributions was analyzed,and the shape parameters with the best cooling performance were obtained.Compared with the cooling performance of the uniformly filled structure,its cooling performance has increased by 5.05％,indicating that through a reasonable non-uniform filling design,the cooling performance of the triply periodic minimal surface cooling structure can be effectively improved.
