Abstract (en)

[origin: WO2021170232A1] The invention relates to a heating device having a flat expanded support and at least one heating conductor assembly thereon which is electrically connected by means of two connection contacts. The heating conductor assembly has a plurality of heating conductors which are connected together at connection points and are wired as a whole so as to form parallel and series circuits between the connection contacts. The plurality of heating conductors are advantageously designed as a lattice, wherein every set of four heating conductors forms a closed mesh, and four heating conductors are connected together at the connection points. The heating conductor assembly is applied onto the support with a film construction in a film method, advantageously a thick-film method.
