Abstract
A metal honeycomb body includes at least two disks being mutually spaced apart and disposed one after the other relative to an axis. Each of the disks has a multiplicity of channels formed therein through which a fluid can flow along the axis. At least one support connects the disks to one another in the vicinity of the axis. The at least one support is tubular, bar-shaped or rod shaped.

A metal honeycomb body through which a fluid can flow in a direction along an axis thereof, comprising:
- a) first and second honeycomb disks defining a space therebetween and being disposed one after the other relative to an axis along which a fluid can flow through the honeycomb disks, each of said disks having two end surfaces aligned approximately perpendicular to the axis;
- b) each of said disks having a multiplicity of channels formed therein through which the fluid can flow along the axis;
- and
- c) at least one support extending axially across said space and connecting said disks to one another, said at least one support being selected from the group consisting of tubular, bar-shaped and rod-shaped supports;
- wherein said first disk is at least partially electrically conductive, said first disk defies a current path therein for the passage through said first disk of an electric current for heating, and said at least one support includes at least one electrically insulating support through which said first disk is braced against said second disk.
A metal honeycomb body through which a fluid can flow in a direction along an axis thereof, comprising:
- a) first and second honeycomb disks defining a space therebetween and being disposed one after the other relative to an axis along which a fluid can flow through the honeycomb disks, each of said first and second disks having two end surfaces aligned approximately perpendicular to the axis;
- b) each of said first and second disks having a multiplicity of channels formed therein through which the fluid can flow along the axis;
- and
- c) at least one support extending axially across said space and connecting said disks to one another, said at least one support being selected from the group consisting of tubular, bar-shaped and rod-shaped supports;
- wherein:
- said channels of each of said disks have cross-sectional areas being perpendicular to the axis and having a given mean value;
- each of said disks has a mean cross-sectional area corresponding to the given mean value;
- and the mean cross-sectional area of said first disk is greater than the mean cross-sectional area of said second disk.
