Title: Heating sheet bundle for regenerative heat exchangers

Abstract: A heating sheet bundle to be mounted tangentially or radially in trapezoidally segmented cells of heating surface carriers of regenerative heat exchangers with stationary or revolving storage masses is composed of a plurality of profiled sheets which are stacked on top of each other and are held together so as to form passage ducts therebetween. On at least two oppositely located sides of the bundle, at least the two outer profiled sheets are constructed as a pair of sheets connected in a dimensionally stable, sandwich-like manner. One of the profiled sheets of the pair of profiled sheets is undulated and the other of the profiled sheets of the pair of profiled sheets is corrugated, wherein the rolling depth of the undulated sheet is greater than the rolling depth of the corrugated sheet.
