文摘A static model of the forced cooling of inductors used for induction heating is proposed in order to achieve better coil design to prolong its lifetime and prevent failures.The main aim is to define for the most common copper tubes and inductor geometries an equivalent convection heat transmission coefficient depending upon temperature and pressure of the cooling fluid,in order to model the very complex physics of forced cooling with a strongly simplified method.The model,called 'Line Region Model',considers only the coil's copper tube and its internal surface(interface copper-water)as boundary where the heat exchange conditions are imposed.
