Heat exchanger

Image Number 7 for United States Patent #4854380.

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.
