Abstract
A honeycomb body for the chemical conversion of at least one component of a gas stream, in particular an exhaust-gas stream from an internal combustion engine, includes an inflow passage having an axis, and sheet-metal layers. At least some of the sheet-metal layers are structured to form two sets of crests and passages through which the gas stream can flow. Each of the sets of crests of each of the sheet-metal layers define a respective plane. The sheet-metal layers are segmented in circumferential direction of the honeycomb body. The axis and the plane include an angle of between 45° and 135°, preferably between 70° and 110°. The radial honeycomb body is particularly easy to produce.
Claims22
A honeycomb body for the chemical conversion of at least one component of a gas stream, comprising:
- an inflow passage having an axis;
- and
- sheet-metal layers, at least some of said sheet-metal layers being structured to form two sets of crests and passages through which the gas stream can flow, each of said sets of crests of each of said sheet-metal layers defining a respective plane;
- said sheet-metal layers being segmented in the circumferential direction of the honeycomb body define segments of a ring, each of said segments being delimited by first and second arc sections and two sides, said sides of said segments being disposed adjacent one another to form said ring;
- and
- said axis and said plane including an angle of between 45° and 135°.
