Abstract
A honeycomb body, especially a catalyst carrier body, includes at least partly structured metal sheets forming walls of a plurality of channels through which a fluid can flow. Some of the sheets have a primary corrugation with crests, troughs and a given corrugation height. The crests and/or the troughs having a plurality of inverted regions with a height being at most equal to the given corrugation height and preferably between 1/3 and 2/3 of the given corrugation height.
Claims30
Honeycomb body having end surfaces and an interior, comprising at least partly structured metal sheets forming walls of a plurality of channels through which a fluid can flow, some of said sheets having a primary corrugation with crests, troughs and a given corrugation height, and at least one of said crests and said troughs having a plurality of inverted regions with a height being at most equal to said given corrugation height and having a quantity per unit of volume increasing from one of said end surfaces to the other as seen in the direction of said channels formed by said primary corrugation, said inverted regions defining leading edges in the interior of the honeycomb body.
Honeycomb body according to claim wherein said inverted regions are approximately in the shape of teeth of an involute gear.
Honeycomb body having an interior, comprising at least partly structured metal sheets forming walls of a plurality of channels through which a fluid can flow, some of said sheets having a primary corrugation with crests, troughs and a given corrugation height, each of said crests and each of said troughs being formed with at least two inverted regions of different heights being at most equal to said given corrugation height, and said inverted regions defining leading edges in the interior of the honeycomb body.
Honeycomb body having an interior, comprising at least partly structured metal sheets forming walls of a plurality of channels through which a fluid can flow, some of said sheets having a primary corrugation with crests, troughs and a given corrugation height, each of said crests being formed with at least two inverted regions of different heights being at most equal to said given corrugation height, and said inverted regions defining leading edges in the interior of the honeycomb body.
