Title (EN) HEAT EXCHANGER TUBE
(FR) TUBE D'ÉCHANGEUR DE CHALEUR
Abstract:
(EN) A flat tube for a heat exchanger is fabricated from a single sheet of metal material. The sheet of metal material has a first edge and a second edge, which are arranged adjacent to one another between a pair of broad walls of the tube. Flat sections extend from the edges and are disposed against one another. A pair of rounded walls arranged at an end of the tube connect the flat sections to the broad walls, and are joined by a weld bead within a space bounded by the outer surfaces of the rounded walls.
(FR) L'invention concerne un tube plat pour un échangeur de chaleur, le tube étant fabriqué à partir d'une seule feuille en matériau métallique. La feuille en matériau métallique comporte un premier bord et un second bord disposés adjacents l'un à l'autre entre une paire de parois larges du tube. Des sections plates s'étendent à partir des bords et sont disposées l'une contre l'autre. Une paire de parois arrondies, disposées au niveau d'une extrémité du tube, relient les sections plates aux parois larges, et sont assemblées par un cordon de soudure à l'intérieur d'un espace délimité par les surfaces externes des parois arrondies.
