Abstract:
PCT No. PCT/SE88/00083 Sec. 371 Date Aug. 4, 1989 Sec. 102(e) Date Aug. 4, 1989 PCT Filed Feb. 25, 1988 PCT Pub. No. WO88/06709 PCT Pub. Date Sep. 7, 1988.A pack of heat transfer plates (2,3) are intended for heat exchangers, preferably for rotary regenerative air preheaters. The plates have mutually parallel S-shaped double ridges (21,22;31,32) and the plates are arranged in the pack (1) so that the double ridges of one plate intersect the double ridges of an adjacent plate and extend symmetrically and obliquely in mutually opposite directions relative to the main flow directions (6) of the heat exchanging media. The throttling effect normally manifest at the double-ridge intersections (24) is avoided by orienting the plates (2,3) so that each pair of double ridges which converge onto an intersection (24) presents a part (21) of the double ridge of the one plate (2) which projects into an intermediate channel, and also a part (32) of the double ridge of the other plate (3) which projects from the intermediate channel.
