A heating device has a support and a heating element arranged on it, the heating element having two electrical terminals and a multiplicity of heating conductors that are electrically connected to one another. Starting from the one terminal, the heating element is divided into a number of heating conductors parallel to one another and in series one behind the other toward the second terminal. In this case, at least three heating conductors are connected in parallel next to one another and at least three heating conductors are connected in series one behind the other. Series-connected heating conductor groups can be formed, heating conductors being parallel within a heating conductor group.

Heating device

A heating device for filter elements of a soot filter, as well as a soot filter are described. The filter elements are disk-shaped and stacked on one another in said soot filter. The heating device has a tubular heater with an outer tube and a heating conductor located therein. The essence of heating device is a very small diameter of the tubular heater compared with conventional tubular heaters. It is also constructed in such a way that its path covers a certain area. This can e.g. be a quadrant or semi-circle in a round filter element. The arrangement of the tubular heater in the soot filter is such that it passes close to the filter surface of the filter elements.
