Embodiment Construction

[0041] figure 1 A honeycomb body 1 is shown schematically as a component in an exhaust gas purification system 4 of a motor vehicle 15 (only shown here). Here, the honeycomb body 1 is formed from a housing 2 and a honeycomb structure 3 (only shown here) arranged in the housing 2 . In this case, the housing is formed from a sheet metal 5 with projections 7 and a regular edge profile 8 (only partially shown).

[0042] In this case, the housing 2 has a section 6 running around the circumference of the housing 2 , in which the sheet metal 5 is formed solely by the projection 7 and the edge contour 8 . Here, the edge contours 8 are each completely at the periphery The protrusion 7 is surrounded. The section 6 terminates at a connection region 16 of the housing 2 with the widened edge profile 8 (connection). figure 2 to follow figure 1 The cross-section taken along the line A-A shows by way of example the shape selected here for the projection 7 and the edge contour 8 . In a...

Abstract

The present invention relates to a honeycomb body (1) having at least one housing (2) and a honeycomb structure (3) for a waste-gas purification system (4) having at least one sheet material (5), wherein the sheet material (5) has elevations (7) in at least one section (6) and an edge contour (8) enclosing the elevations (7) and a portion of the area of the elevations (7) in the at least one section (6) is at least 80 %.

Description

technical field [0001] The invention relates to a honeycomb body for an exhaust gas purification system, the honeycomb body having a housing and a honeycomb structure, the honeycomb body having a sheet metal which has projections in a section and surrounds the projections The edge profile of the exit. The invention also relates to the use of such honeycomb bodies in the automotive sector. Background technique [0002] The prior art discloses a large number of metallic exhaust gas purification components of different designs, for which various metal materials and / or shapes are proposed for the individual components. In this case, sheet metal / sheet metal is used, for example, as a component part of the housing, as a sleeve, as an intermediate layer or to produce a honeycomb structure composed of thin structured or smooth sheets / metal sheets. [0003] It is known for the housing region to provide channels, grooves etc. on the inside which are to be able to influence the flux ...
