| Abstract Scope |
The higher design flexibility offered by additive manufacturing (AM) allows for radical improvements in the design and functionality of legacy parts for several energy applications. In this current study, a cross-flow/air-cooled heat sink is designed and optimized using the ANSYSŪ topology optimization module. Unlike many other design/optimization approaches for AM, the current method employs a multi-objective scheme for mass reduction and conjugate heat transfer maximization. A gradient-based adjoint solver is used along with ANSYS’s computational fluid dynamics (CFD) package to seek the optimal shape for a given set of heat sink operating conditions. Pin-fin array and gyroid-based heat sink concepts were used for ‘seeding’ the multi-objective topology optimization routines and the results are compared and discussed. Topology design and operating (boundary condition) variables were varied to elucidate major design sensitivities. In all cases, the optimized heat sink design performed significantly better than its benchmark in terms of thermal efficiency. |
