Efficiency Study of Passive Cooling Structures Using Topological Optimization

Possibilities for optimizing the design of self-cooled radiators were investigated. The SIMP method can be used for topologically optimizing the steady-state thermal conductivity of a flat plate with the Dirichlet condition on the lateral edge and uniform heat release throughout the volume. A radiator with optimal topology geometry was constructed using wire EDM cutting technology. The results of the heat removal efficiency comparison for topologically optimized radiators and conventional finned radiators are presented in the form of their temperature fields. Studies have demonstrated the high efficiency of a topologically optimized radiator design heat removal in comparison with finned ones. Recommendations for the practical application of the results obtained are formulated.
