I have a power-board inverter destined for a modern battery-electric vehicle and I need a complete thermal solution developed around it. The work starts with accurate 3-D modelling of the board, then moves into designing an aluminium heatsink that houses an internal liquid-coolant channel. Every design decision must be validated in ANSYS/COMSOL, as that is the simulation environment we use in-house. The study has three inseparable goals: maximise heat-dissipation efficiency, keep every critical component within its target temperature window, and optimise the coolant flow path so pressure drop stays reasonable. You are free to choose the most suitable ANSYS modules—Icepak, Fluent, Mechanical, or Workbench—as long as the final package covers both conjugate heat transfer and CFD. Deliverables • Parametric CAD model of the aluminium heatsink with embedded coolant channel • ANSYS project files, meshes and boundary-condition setups ready for peer review • A concise report (PDF) detailing assumptions, material data, simulation results, thermal maps, flow visualisations, and design recommendations Acceptance will be based on meeting the temperature limits I provide after kickoff, achieving a verified pressure drop below our target, and supplying files that reproduce all results without errors on our workstation.

The key challenge here is balancing component temperature limits with coolant pressure drop, not simply designing a heatsink. I can develop the aluminium cold-plate/heatsink with an optimized internal coolant channel and validate it in ANSYS Fluent/Icepak using conjugate heat transfer + CFD. I can provide the parametric CAD, ANSYS project/mesh/BC setup, temperature & flow results, pressure-drop verification, and concise technical report with a reproducible simulation workflow. Could you share the PCB/inverter geometry, heat loads for the critical components, coolant type/inlet temperature/flow rate, and target pressure drop? Budget and timeline can be finalized after discussing the scope and available input data.

I have hands-on experience with ANSYS Fluent and Workbench, including conjugate heat transfer, fluid flow, thermal analysis, meshing, parametric studies, and interpreting simulation results to improve engineering designs. I have also worked on Multiphysics problems in COMSOL involving heat transfer, fluid flow, porous media, and coupled physics, which gives me a strong foundation for understanding the underlying thermal-fluid behavior rather than treating the simulation as a black box. For your inverter, I would focus on: * Developing an accurate 3-D representation of the board and heat-generating components. * Creating a parametric aluminium heatsink with integrated liquid-cooling channels. * Setting up conjugate heat transfer and CFD in ANSYS. * Evaluating component temperatures, heat flux, coolant velocity and pressure drop. * Iterating channel geometry and flow conditions to maximise cooling while maintaining an acceptable pressure drop. * Performing mesh/convergence checks and documenting assumptions and boundary conditions for peer review. * Delivering reproducible ANSYS project files and a concise technical report with thermal maps, flow visualizations and design recommendations. I understand that the final design is not simply the one with the lowest temperature—it needs to achieve the required thermal limits, pressure-drop target, manufacturability, and repeatable simulation results.
