Abstract (en)

A heat exchanger includes a plurality of first fluid passages 45 configured to receive a first stream and a plurality of second fluid passages 43 each formed between two first fluid passages. Each first fluid passage includes a first plate and a second plate 46 parallel to the first plate. The first plate and second plate are connected by two closure bars. The first fluid passage also includes a fin pack 60 having a plurality of fins connected to the first and second plate, and configured for the first stream to flow around the fins. The fins have a cross-sectional profile that is bowed at non-operational temperatures and is configured to flex under a thermal load without exceeding the tensile or fatigue strength of the fin. Each second fluid passage is configured to receive a second stream and is configured to allow heat to indirectly exchange between the first stream and the second stream.
