Abstract

A honeycomb body includes at least one housing and a honeycomb structure for a waste-gas purification system having at least one sheet metal material. The sheet metal material has elevations in at least one section and an edge contour enclosing the elevations. A portion of the area of the elevations in the at least one section is at least 80%. A particle separator, a catalyst carrier body and a motor vehicle having the honeycomb body are also provided.

Claims (20)

1. A honeycomb body, comprising:

at least one housing;

a honeycomb structure for an exhaust-gas purification system;

at least one sheet metal material being a structured foil having a surface and forming at least one of said honeycomb structure or said at least one housing, said at least one sheet metal material including at least one portion extending entirely over said surface and having elevations and edge contours surrounding said elevations;

said elevations in said at least one portion having an area percentage of at least 80%;

at least one of said at least one sheet metal material or said at least one housing having a sheet metal thickness;

said elevations having a height measured from said edge contours; and

said height corresponding to at most six times said sheet metal thickness.

2. The honeycomb body according to claim 1 , wherein said at least one portion, having said elevations and said edge contours surrounding said elevations, has a uniform degree of deformation of said sheet metal material.

3. The honeycomb body according to claim 1 , wherein said honeycomb structure has at least one channel defined by at least one first wall formed at least partially by said structured foil and at least one second wall formed at least partially by an element selected from the group consisting of a corrugated layer, a smooth layer and a nonwoven.

4. The honeycomb body according to claim 3 , wherein at least one of said structured foil or said element has openings and is free of fittings.

5. A particle separator for exhaust-gas treatment of internal combustion engines, the particle separator comprising:

a honeycomb body according to claim 1 for exhaust-gas treatment of internal combustion engines.

6. A catalyst carrier body for exhaust-gas treatment of internal combustion engines, the catalyst carrier body comprising:

a honeycomb body according to claim 1 for exhaust-gas treatment of internal combustion engines.

7. A motor vehicle, comprising:

a honeycomb body according to claim 1 .

8. The honeycomb body according to claim 1 , wherein said edge contours form a closed embracing for each of said elevations and provide boundaries between adjacent elevations having at least one of a stripe shape or a line shape.

9. The honeycomb body according to claim 1 , wherein said edge contours have a shape selected from the group consisting of triangular, quadrangular, pentagonal and polygonal.

10. The honeycomb body according to claim 1 , wherein all of said elevations in said at least one portion have the same area, height and shape.
