Abstract

La présente invention concerne un échangeur de chaleur disposé dans un canal d'écoulement. Un tube de l'échangeur de chaleur, qui conduit un premier fluide, est extérieurement pourvu de nervures et/ou de lamelles orientées parallèlement au sens d'écoulement d'un second fluide qui est transporté par le canal d'écoulement et qui entoure en s'écoulant l'extérieur du tube, de façon à transférer l'énergie thermique du premier au second fluide ou du second au premier fluide. En l'occurrence, l'ensemble de l'échangeur de chaleur ou des zones partielles de l'échangeur de chaleur est ou sont capable(s) de basculer autour d'un ou de plusieurs axe(s) transversaux, et en particulier à la perpendiculaire des surfaces latérales des nervures et/ou des lamelles.
