In this study, the optimum design of load carrying structures that can also exchange heat with a coolant is presented. The level set topology optimization method is used as the design tool. The topology of the structure is modeled as a 2D geometry for ease of manufacturing, and the physics is simulated using 3D models. The flow is modeled using the Darcy potential flow, and the heat transfer is modeled using the convection-diffusion equation. The displacement field is computed using a linear-elasticity model. The compliance of the structure under different loading conditions and boundary conditions, subject to a volume and temperature constraints is minimized. The role played by the loading and boundary conditions on the optimum topologies of load carrying heat exchangers is investigated.
