Abstract
A heating conductor for an exhaust gas heating arrangement for an exhaust gas system for an internal combustion engine includes a plurality of heating conductor sections. At least one throughflow opening, preferably a plurality of throughflow openings through which exhaust gas can flow, is or are provided in at least one heating conductor section, preferably in a plurality of heating conductor sections or in each heating conductor section.
Claims8
A heating conductor for an exhaust gas heating arrangement for an exhaust gas system for an internal combustion engine, the heating conductor being configured to be plate-like and being cut out from a metal flat material and comprising:
- a plurality of heating conductor sections extending in a heating conductor section longitudinal direction (H), wherein at least one of:
- a first portion of said plurality of heating conductor sections are arranged to form a configuration of the heating conductor wound in a meandering manner at least in regions thereof, and,
- a second portion of said plurality of heating conductor sections form a configuration of the heating conductor wound spirally at least in regions thereof;
- at least one throughflow opening provided in at least one of said plurality of heating conductor sections for passing exhaust gas therethrough, said at least one throughflow opening being elongated in a through flow opening longitudinal direction (D) corresponding to said heating conductor section longitudinal direction (H) and having a longitudinal end region;
- and,
- a flow-conducting element in association with said at least one throughflow opening, said flow-conducting element being configured to extend, starting from said longitudinal end region, in said through flow opening longitudinal direction (D) at least partially along said throughflow opening.

An exhaust gas heating arrangement for an exhaust gas system for an internal combustion engine, the exhaust gas heating arrangement comprising:
- an exhaust gas conducting housing for conducting a flow of exhaust gas in a main flow direction;
- a carrier arrangement held in said exhaust gas conducting housing;
- at least one heating conductor mounted on said carrier arrangement;
- said at least one heating conductor being configured to be plate-like and being cut out from a metal flat material and comprising:
- a plurality of heating conductor sections extending in a heating conductor section longitudinal direction (H), wherein at least one of:
- a first portion of said plurality of heating conductor sections are arranged to form a configuration of the at least one heating conductor wound in a meandering manner at least in regions thereof, and,
- a second portion of said plurality of heating conductor sections form a configuration of the at least one heating conductor wound spirally at least in regions thereof;
- at least one throughflow opening provided in at least one of said plurality of heating conductor sections for passing exhaust gas therethrough, said at least one throughflow opening being elongated in a through flow opening longitudinal direction (D) corresponding to said heating conductor section longitudinal direction (H) and having a longitudinal end region;
- a flow-conducting element in association with said at least one throughflow opening, said flow-conducting element being configured to extend, starting from said longitudinal end region, in said through flow longitudinal direction (D) at least partially along said throughflow opening.
