Abstract (en)
[origin: EP0947793A2] A finned-tube heat exchanger, particularly for combined-cycle systems and the like, which comprises a plurality of finned tubes (1) arranged in rows with fins (2) which comprise two parts, respectively a proximal part (3), which is solid and fixed to the surface of the tubes (1), and a segmented distal one (4); the particularity of the exchanger is that if p is the distance between two solid proximal parts (3) of two adjacent fins (2), the distal parts (4) of some fins (2) are bent away from the median plane of the fins (2) themselves, so that the distance between the distal part (4) of the bent fins (2) and the distal part (4) of a consecutive fin (2) is between 0.3 and 1.7 p. <IMAGE>
