This study aims to study numerically the free convection and thermal radiation of an Ag‐water nanofluid inside an L‐shaped inclined microelectronic module under inclined Lorentz forces and uniform heat generation/absorption effects. The study is established using the software COMSOL Multiphysics based on the finite element method. The main results obtained show that convection heat flow enhances by increasing the Rayleigh number, radiation parameter and nanoparticles shape factor, however, it reduces with increasing the Hartmann number and the aspect ratio. In addition, the presence of uniform heat absorption improves the convection heat flow, by contrast, the presence of uniform heat generation damages this. Besides this, the Lorentz forces' directional impact on the convection heat flow is linked to module inclination. The average Nusselt reaches a maximum for module inclination γ = 45 ° .
