Wabenkörper, insbesondere Katalysator-Trägerkörper,mit verstärkter Wandstruktur

摘要

A honeycomb body (1), in particular a catalyst support body, has stacked and/or wound sheet metal layers (17; 18) of which at least some are structured sheet metal layers (18), forming channels through which a fluid can flow. Part of the sheet metal layers (17; 18) has a first thickness (a) and part of the sheet metal layers (17; 18) has a second thickness (b) larger than the first (a). The honeycomb body (1; 21) contains a lattice-like structure (4; 14) formed by at least two sheet metal layers (17; 18) of the second thickness (b), of which at least one is a structured sheet metal layer (18), these layers being joined to one another at least in some areas. These honeycomb bodies, while being very stable, can have particularly thin sheet metal layers, so that at least locally they have a particularly low heat capacity.
