Abstract
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 wave form in the direction of the flow of a fluid, the bends in one heat-transfer element (1 ) being in phase with those in an adjacent heat-transfer element (1) 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 not only provides improved heat-transfer characteristics; it also serves to offer a lighter product because of the presence of throught-holes (3).
