Publication number: 20190289674Abstract: An electrical heating device for mobile applications, includes a substrate and a heat-conducting layer formed on the substrate. The heat-conducting layer has at least one heat-conducting track that is arranged on the substrate, and the heat-conducting track is structured such that a multiplicity of track sections, separated from one another by insulating gaps, is formed. The heat-conducting track has at least one deflection section at which the heat-conducting track is deflected and which is arranged between a first and a second track section, wherein the first and the second track section have a smaller curvature in comparison with the deflection section. The heat-conducting track in the first track section or in the deflection section branches into at least two branch tracks separated from one another by one or more branch insulating gaps. The branch tracks meet up again in the second track section or in the deflection section.Type: ApplicationFiled: October 5, 2017Publication date: September 19, 2019Inventors: Tino KLINKMÜLLER, Stephan BUCKL, Daniel ECKERT, Karl GÖTTL, Andreas SCHMIDMAYER
