A process for the preparation of a profiled sheet metal material and a device for this purpose, as well as profiled sheet metal material, metallic composite body formed from this sheet metal material and catalyst

摘要

The present invention relates to a process for the manufacture of a profiled sheet metal material as well as a device for this purpose, a profiled sheet metal material as well as a composite body, in particular a catalyst - carrier body and a catalyst, with the present invention provides for the corrugated duct-forming structures of the composite body of shaping technology - or catalyst carrier body to be provided with undercuts, so that intermediate layers between the flow channel image ends of the corrugated profile layers as well can be dispensed with, such as to solder between the individual layers. The present invention is also included for the production of the catalysts can be used, without being limited thereto. It can rather also in the area of the construction of heat exchangers or refrigerant condensers for motor vehicles - air conditioning systems are used.
