Abstract

La présente invention concerne un échangeur de chaleur comprenant : un collecteur dans lequel une pluralité de parties rainure, évidées de manière concave à partir de l'extrémité, est formée entre des languettes courbées espacées les unes des autres le long de la circonférence ; et un réservoir accouplé au collecteur, formant ainsi un espace d'écoulement pour un fluide d'échange de chaleur. L'extrémité inférieure du réservoir est introduite dans le collecteur, et les languettes courbées sont courbées vers l'intérieur et accouplées au réservoir. Une première partie rainure, plus profonde que les parties rainure, est formée dans le collecteur. Par conséquent, une déformation thermique provoquée par une différence de température est facilement permise, réduisant ainsi la contrainte thermique et permettant d'empêcher des fuites du fluide d'échange de chaleur.
