Abstract
A heating device comprises a heating element having a central area and a peripheral edge. The heating element has a series of slots delimiting a series of longitudinal branches connected to one another by elbows. The central area is made of a first electrically conductive material that is permeable to exhaust gases and has a first relative density. The elbows are located in the peripheral edge and are made of a second electrically conductive material and that has a second relative density greater than the first relative density.
Claims17
A heating device for an exhaust gas purification member, the heating device comprising:
- a heating element having a central area and a peripheral edge surrounding the central area;
- the heating element having a series of slots, the series of slots defining an S-shaped path through the heating element;
- the series of slots delimiting a series of longitudinal branches in the heating element, connected to each other by elbows and transversely offset from each other;
- the central area being made of a first electrically conductive material, permeable to exhaust gases and having a first relative density;
- the elbows being located in the peripheral edge, the elbows being made of a second electrically conductive material and having a second relative density greater than the first relative density, wherein relative density is defined as a ratio between a density of a specified material and a density of a metallic material constituting the specified material in a solid state without pores.
