Abstract:
This paper uses the lattice Boltzmann method with turbulence model to simulate the thermal performance of power module with Pinfin heatsink. The simulated properties include inlet and outlet pressure drop and flow velocity around the cylinders of Pinfin. With the feature of fast simulation speed and easy coding, it is easy to be integrated into optimization algorithms. With the method, the selection of the diameter and spacing of the cylinders was optimized to improve the heat dissipation performance. The simulation results with CFD and experimental results verified the improvement of the heat dissipation performance.
