Abstract

A device for removal of heat from cores (2) of ferromagnetic material of inductive components includes a layer (4) of electrically and thermally conductive material applied to the core (2) and via which material the core is thermally coupled to a heat-sink (3). The electrically and thermally conductive layer is specifically a metal layer i.e. of copper or silver, provided with discontinuities to avoid inducing electrical currents into closed electrically conducting paths.
