Abstract
An electric heating device in an exhaust gas system, the device having an outer circumferential, circular, housing, wherein a rib structure is arranged in the housing. The rib structure can be heated by applying an electric current. The rib structure is arranged with rib rows parallel to one another in the housing, wherein the parallel-arranged rib rows are arranged such that they are electrically connected to one another in series or in parallel.
Claims17
An electric heating device in an exhaust gas system, the electric heating device comprising:
- an outer circumferential housing;
- and a rib structure arranged in the housing, wherein the rib structure is heatable in response to an electric current applied thereto, the rib structure comprises a plurality of rib rows parallel to one another in the housing, each rib row of the plurality of rib rows comprises a plurality of ribs, the plurality of rib rows are electrically connected to one another in series or in parallel, wherein two holding rods extend through the plurality of rib rows to hold the plurality of rib rows in place within the housing, and wherein each rib row of the plurality of rib rows has widened regions through which the two holding element extend.
