Abstract
A rotary regenerative heat exchanger (2) for transferring heat from a hot fluid to a cold fluid by means of an assembly (30) of heat transfer element which is alternately contacted with the hot and cold fluid. The heat transfer element assembly (30) is comprised of a plurality of first and second heat absorbent plates (32,34) stacked alternately in spaced relationship. The spacing between adjacent first and second plates (32,34) is maintained by spacers which comprise V-shaped folds (38A and 38B) crimped in the first plates (32) and second plates (34), respectively, at spaced intervals along the plates. The folds (38A) in the first plates (32) are spaced equally apart by a first interval, while the folds (38B) in the second plates (34) are also spaced equally apart but at a second interval which is not equal to the first interval. In this manner, the folds in adjacent plates will not line up and nesting of adjacent plates is precluded.
