This paper presents a mathematical model and its finite element (FEM) implementation for the thermoelectric processes that occur in a Peltier sink-and-fan device aimed at enhancing the heat exhausted by power electronics. The heat transfer management for several key parameters (the heat released by the electronic module, the ambient temperature, the convection heat transfer coefficient) is analyzed to find optimal working conditions.
