Abstract
A conical honeycomb body includes a tubular casing which is conical with respect to an axis. At least one stack in the casing is formed of at least one layer at least partially having waves. The layers bound a plurality of channels through which a fluid can flow. Structures extending substantially in axial direction of the honeycomb body project from the waves of the layers.
Claims16
A conical honeycomb body, comprising:
- an axis defining an axial direction;
- a casing tube having a conical shape relative to said axis;
- at least one stack disposed in said casing tube and formed by
- at least one metal layer at least partially having waves, said
- at least one stack having a plurality of channels for conducting a fluid flow through said channels;
- and
- a multiplicity of structures projecting from said waves and extending substantially in said axial direction.

A conical honeycomb body, comprising:
- an axis defining an axial direction;
- a casing tube having a conical shape relative to said axis;
- at least one annular layer having an outer arc and an inner arc, wherein each of at least one annular layers, at least partially has waves;
- at least one stack disposed in said casing tube and formed by said at least one annular layer, wherein:
- said at least one stack has a plurality of channels formed by said waves for conducting a fluid flow,
- at least one of said waves has an outer crest at said outer arc that merges into two waves along said inner arc,

- a mutual inner trough lies between said first inner crest and said second inner crest;
- and
- a multiplicity of structures projecting from said waves and extending substantially in said axial direction.
