| Abstract: |
| The actively cooled performance of a particular cylindrical sandwich shell with cellular materials was analyzed,and the thermal performance indexes of cellular materials with different heat transfer boundary conditions were derived respectively.The particular cylindrical sandwich shell with cellular materials has an equal cell number,a consistently relative density of each layer,and a growing cell size with the extension of the outer diameter.The thermal performance index of cellular materials with three different heat transfer boundary conditions were derived respectively,the relationships between the layer number of cylindrical sandwich cellular materials and the maximum thermal performance index,the optimal relative density were analyzed,and then the minimum weight was achieved.The regular hexagonal cell had superior active heat dissipation performance and relatively lighter weight than others. |
