Thermal Characteristics of Sandwich Plates with Prismatic Cores

In this paper are analyzed thermal characteristics of sandwich plates with prismatic core in order to optimize their geometry. Open structure of sandwich plates makes them convenient for cooling: the fluid flows through the open channels in the core and takes away the heat which can act on one or both surfaces of the plate. The construction of sandwich plates with prismatic core is also convenient for application where good heat conduction and high carrying capacity are requested simultaneously. If one bears in mind this double application, the task is to perform the optimization of the sandwich plate's geometrical parameters in order to apply various combinations of structural and thermal loads. Results presented in this paper provide possibility for large geometrical flexibility in combining thermal and structural characteristics optimization.
