Abstract

La présente invention concerne un échangeur de chaleur qui est équipé de tubes échangeurs de chaleur 30, chacun comportant des surfaces plates 33 et 35 formées avec des parties évidées et saillantes en forme d'onde 34, 36. Les parties évidées et saillantes en forme d'onde 34, 36 sont formées avec des lignes supérieures 34a, 36a et des lignes inférieures 34b, 36b alternant mutuellement. Les lignes supérieures 34a, 36a et les lignes inférieures 34b, 36b ont chacune une forme telle que des formes en V soient horizontalement raccordées, chacune des formes en V comportant une partie de flexion courbée. Par conséquent, il est possible de réduire la concentration de contrainte sur les parties de flexion pendant un traitement de pressage par rapport à des tubes échangeurs de chaleur qui ont les formes en V de lignes supérieures et lignes inférieures horizontalement raccordées de manière à comporter des parties de flexion à angle aigu. En conséquence, lorsque les amplitudes des parties évidées et saillantes en forme d'onde 34, 36 sont amenées à être égales, les rendements pendant le traitement de pressage peuvent être augmentés et, lorsque les rendements pendant le traitement de pressage sont amenés à être égaux, les amplitudes des parties évidées et saillantes en forme d'onde 34, 36 peuvent être augmentées.
