| 摘要: |
| 通过推导变厚度胞体壁多孔夹层材料的散热系数，研究了胞体壁的厚度变化对多孔夹层材料主动散热性能的影响。分析了胞体壁厚度变化下，不同胞体构型多孔夹层材料的相对密度与散热系数的关系，并得到了不同胞体构型多孔夹层材料的最大散热系数和最佳相对密度。通过线性拟合，给出了最大散热系数和最佳相对密度与变厚度参数的关系，探讨了胞体壁厚度变化对不同胞体构型多孔夹层材料的最佳相对密度和最大散热系数的影响，并得到如下结论：胞体壁厚度变化对六边形单元的主动散热能力影响小，而对三角形和正方形单元的影响大。 |

| Abstract: |
| The influence of the thickness variation of the cell wall on the active heat dissipation of the cellular sandwich was studied by deducing the thermal performance index of the cellular sandwich with variable thickness. The relationship between the relative density and the thermal performance index of the cellular sandwich with different cell structures was analyzed. Then, the maximum thermal performance index and the optimum relative density of the cellular sandwich with different cell structures were obtained. The relationship between the maximum thermal performance index and the optimal relative density and the variable thickness parameter was given by using linear fitting. The influence of the thickness of cell wall thickness on the optimal relative density and maximum thermal performance index of different cell structures was analyzed. It was concluded that the change in cell wall thickness has the slight effect on the hexagon, and the effect on the triangle and square is big. |
