Title
(EN) HEAT TRANSFER SHEET ASSEMBLY WITH AN INTERMEDIATE SPACING FEATURE
Abstract
(EN)

A heat transfer sheet assembly for a rotary regenerative heat exchanger has first and second heat transfer sheet elements stacked one against the other with a first repeat of a first profile on one sheet element opposing a second repeat of a second profile on the other sheet element. The sheet elements are spaced apart by a plurality of wide-gauged parallel sheet spacing features of the first profile repeat R1 of the second profile repeat to form a generally close sided elongate channel for gaseous flow therethrough. The second profile of repeat includes an elongate fifth sheet spacing feature in the form of a lobe contacting undulations of the adjacent first profile of repeat.
