Abstract
A metal sheet having a microstructure, a carrier body having a plurality of sheets, and an exhaust system having the carrier body, are distinguished by a particularly long useful life in an automobile. Moreover, it is possible to bring about flow profiles coordinated exactly with the respective fields of use, so that a particularly efficient or extremely adaptable carrier body for purifying the exhaust gas of automobiles is provided.
Claims9
A metal sheet, comprising:
- an inner region;
- a surface structure;
- at least one slit disposed in said inner region;
- and
- a microstructure at least partially delimited by said at least one slit, said microstructure projecting from said surface structure and defining a spherical area, said slit extending in a transverse direction of the sheet, said spherical area being shaped such that various sectional planes taken parallel to the transverse direction each have respective maximum points and respective minimum points, at least said respective maximum points or said respective minimum points are not aligned in a longitudinal direction perpendicular to the transverse direction.
