ABSTRACT:
The invention in connection with regenerative heat exchangers and ways of manufacturing them. The outer wall of the tubular rotor of such a heat exchanger is made up of one or more layers of an embossed aluminum strip that are fixed on edge and running radially outwards and in the form of a structure whose generatrix is a radius moving along a helical path, the structure being supported on an inner core. The embossing process is responsible for producing folds or puckers in the strip at its radially inner edge; furthermore the strip may have a stepped and/or waved form. Because of the helical coiling of the strip on a core, a rotor is produced whose outer wall may be used for the radial motion therethrough of flows giving or taking up heat.
