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.
