CA 2372832
The invention relates to a heat exchanger comprising two manifolds (10). Profiled pipe sections (11) arc accommodated with a lamella configuration (12) between said manifolds. According to the invention, an obstructing means (13) for preventing the flow of solder is provided on the exterior of the profiled pipe section (11) between the manifold (10) and the lamella configuration (12). The invention also relates to a method for producing a heat exchanger. The invention provides that the obstructing means (13) is formed on the profiled pipe sections (11) before the sections are cut from a profiled pipe billet.
L'invention concerne un échangeur de chaleur comportant deux tubes collecteurs (10) logeant entre eux, des sections tubulaires profilées (11) avec un système lamellaire (12). Selon l'invention, il est prévu entre le tube collecteur (10) et le système lamellaire (12), sur la face extérieure de la section tubulaire profilée (11), un élément de blocage (13) pour éviter l'écoulement du métal d'apport. L'invention concerne en outre un procédé permettant de produire un échangeur de chaleur. Selon l'invention, l'élément de blocage (13) est réalisé sur les sections tubulaires profilées (11) avant la séparation par coupe d'un jonc de tube profilé.
