Zusammenfassung:PCT No. PCT/JP86/00521 Sec. 371 Date Aug. 25, 1987 Sec. 102(e) Date Aug. 25, 1987 PCT Filed Oct. 9, 1986 PCT Pub. No. WO87/02762 PCT Pub. Date May 7, 1987.A heat exchanger is disclosed, which comprises a plurality of heat-transfer elements (1) placed side by side each of which has more than one through-hole (3) and which are cyclically bent in a generally trapezoidal waveform in the direction of the flow of a fluid, the bends in one heat-transfer element (1) being out of phase with those in an adjacent heat-transfer element (1) by one-half cycle in such a manner that the main stream of said fluid will flow not through the holes in each of said heat-transfer elements (1) but through the passage formed by adjacent heat-transfer elements (1). This arrangement serves to provide improved heat-transfer characteristics.
