Abstract

A heat exchange element for an air preheater has first and second heat transfer elements arranged to form channels for the passage of a heat exchange media having a main flow direction. Each of the heat exchange plates has parallel straight ridges and flats between the ridges. The ridges alternate to extend transversely from opposite sides of each heat transfer plate. The ridges of the adjacent plates are oriented obliquely in opposite directions relative to the main flow direction and contact each other solely at points of intersection of the ridges.
