Brazing of a folded tube for a heat exchanger includes the controlled prior application of brazing flux to the brazing surface, used for motor vehicle applications
The brazing of a folded tube for a heat exchanger consists of placing a first tube part (20) in contact with a contact surface of a second tube part (22) and brazing the two tube parts at the level of the contact zone using a brazing deposit and a brazing flux to form the brazed liaison. The brazing...

| description | The brazing of a folded tube for a heat exchanger consists of placing a first tube part (20) in contact with a contact surface of a second tube part (22) and brazing the two tube parts at the level of the contact zone using a brazing deposit and a brazing flux to form the brazed liaison. The brazing flux (32) is applied on the contact surface of the second tube part, prior to the brazing operation, in controlled conditions at a distance close to the contact zone. An independent claim is also included for a heat exchanger tube assembled by this method.
Le procédé de brasage de l'invention comprend les opérations consistant à mettre en contact une première partie de tube (20) contre une surface d'appui d'une deuxième partie de tube (22) au niveau d'une zone de contact (Z) et à braser les première et deuxième parties de tube au niveau de cette zone de contact avec utilisation d'un apport de brasage et d'un flux de brasage, le flux de brasage (32) étant appliqué au préalable sur la surface d'appui de la deuxième partie de tube (22) dans des conditions contrôlées à une distance (D) proche de la zone de contact (Z). Application notamment aux échangeurs de chaleur pour véhicules automobiles. |
