Abstract
A catalytic converter for cleaning exhaust from combustion processes, especially exhaust from internal combustion engines, and the manufacturing method thereof, the converter including a housing and a plurality of packets provided therein. Each of the packets includes at least one corrugated foil joined at contact areas to at least one flat foil, preferably by soldering or welding. The flat and/or corrugated foil is provided at least partially with a catalytically active coating. The spaces between the corrugated foil and/or between the at least one flat foil and the at least one corrugated foil define channels running parallel to one another through which the combustion gas flows. At least one electrically heatable foil is connected on or in at least one packet with good heat conduction.
