Abstract:
A heating sheet bundle adapted to be mounted tangentially or radially in trapezoidally segmented cells of a heating surface carrier of a regenerative heat exchanger with stationary or revolving storage masses, the heating sheet bundle comprising a plurality of profiled sheets mounted so as to be placed against each other and forming flow ducts therebetween, wherein at least two outer profiled sections on at least two oppositely located sides of the bundle are constructed as a pair of profiled sheets connected in a sandwich-like manner so as to be dimensionally stable, wherein one of the profiled sheets of the pair of profiled sheets is undulated and another of the profiled sheets of the pair of profiled sheets is corrugated, each sheet having a rolling depth, and wherein the rolling depth of the undulated sheet is greater than the rolling depth of the corrugated sheet.
