For the thermal management of electronics enclosed in a passenger car, a numerical strategy is investigated in this paper. The industrial boundary conditions, including the digital development process and use cases are presented in a first part. A fitting numerical method based on a 3D co-simulation is then described to compute with accuracy the transient temperature of electronics. The convective heat transfer is computed in steady-state with the CFD code STAR-CD and transferred to the FEM code PERMAS for the energy balance at each time-step. The accuracy of the steady-state approach for the prediction of convection is verified for the natural convection and fan forced convection, usual in electronics enclosures. Finally, the numerical strategy is applied to the thermal management of the sound amplifier positioned in a compartment under the passenger feet.
