Abstract
An electrical heating unit H for introduction into the exhaust gas system of an internal combustion engine, in particular upstream with respect to an exhaust gas purification unit, for instance a catalytic converter, which for its operation requires a temperature higher than the ambient temperature, comprises a casing () and at least one resistance heating element () which is designed as a band and is retained inside the casing (), wherein the at least one heating band () is arranged so that it runs in a meandering pattern and with its flat face parallel or substantially parallel to the longitudinal axis of the casing (). The heating unit H also comprises at least one support structure () which is arranged on the end face relative to the heating band () and mechanically connected to the casing () and has slot-shaped heating band bearings () to retain the heating band () inside the casing (), into which slot-shaped heating band bearings () the heating band () engages by an edge portion and via which support structure () the heating band () is electrically insulated from the casing ().
