Each sheet is like one Annular segment shaped so that it is from a with respect to a center approximately circular outer arc and one concentric to this, between this and the center lying approximately circular inner arc limited is. Every structured sheet metal foil has waves. The corrugation of a metal foil has the entire sheet does not have a constant corrugation height.
  • the corrugation height must start out of a smaller corrugation height on the smaller sheet delimiting the sheet metal foil, to a larger corrugation height on the larger sheet-metal sheet enlarge.
  • the ratio of the well heights must be approximately the ratio of Corrugations of the arc correspond, so that when the metal foils are intertwined an conical honeycomb body is created.
  • the partially structured sheet metal sheets according to their Layering and / or winding to a conical film package body, which for a fluid can flow through, in a conical jacket tube with a first and a second front opening, the first front opening having a larger one Has diameter than the second end opening, introduced by mechanical Clamping aids fixed and then at least partially with each other and with the Casing tube connected by joining, in particular soldered.
