Beschreibung
Zusammenfassung:	A heat transfer sheet assembly (7) for a rotary regenerative heat exchanger, has first and second heat transfer sheet elements (8, 9) stacked one against the other with a first repeat R1 of a first profile on one sheet element (8) opposing a second repeat R2 of a second profile on the other sheet element (9). The sheet elements (8, 9) are spaced apart by a plurality of wide-gauged parallel sheet spacing features (21, 22) of the first profile repeat R1 and (23, 24) of the second profile repeat R2 to form a generally close sided elongate channel (25) for gaseous flow therethrough. The second profile of repeat R2 further comprises an elongate fifth sheet spacing feature (26) in the form of a lobe contacting undulations (29) of the adjacent first profile of repeat R1. In an embodiment, the first and second sheet elements each have a composite third profile including both the first repeat of the first profile and the second repeat of the second profile.
