Plates of a heat exchanger plate pack are formed by a stack of plates defining at least two independent fluid flow circuits, each circuit comprising a central heater part and a border with a smooth surface. A cutout is produced on corners of each plate and on the border to be connected, of each plate to the adjacent plate, a fold is made in order to form a first flange. On this first flange a fold is made in order to form a second flange laying parallel to the central part of the corresponding plate and directed outward from the plate. The plates are superposed and held by applying the second flange of each plate to the second flange of the adjacent plate. A continuous sealed weld bead is made by completely melting the second superposed flanges of adjacent plates.

1. A method for assembling the plates of a plate pack for a heat exchanger formed by a stack of plates together defining at least two flow circuits for two independent fluids and each comprising a central heat-exchange part and borders with a smooth surface, comprising: a cutout produced on corners
1. A method for assembling the plates of a plate pack for a heat exchanger formed by a stack of plates together defining at least two flow circuits for two independent fluids and each comprising a central heat-exchange part and borders with a smooth surface, comprising: a cutout produced on corners of each plate; on the border to be connected of each plate to the adjacent plate, a fold is made in order to form a first flange; on this first flange, a fold is made in order to form a second flange lying parallel to the central part of the corresponding plate and directed outward from said plate; the plates are superposed and held by applying the second flange of each plate to the second flange of the adjacent plate; and a continuous sealed weld bead is made by completely melting the second superposed flanges of adjacent plates. 2. The method as claimed in claim 1, wherein a closure plate is placed on the upper part and on the lower part, respectively, of the plate stack, and each closure plate is welded by a continuous sealed weld bead to the flange of the adjacent plate. 3. The method as claimed in claim 1, wherein each side face of the plate stack is partially closed by a covering plate. 4. The method as claimed in claim 1, wherein the second flange forms, with the first flange, an angle equal to or different from the angle formed between the first flange and the central part of the corresponding plate. 5. The method as claimed in claim 4 wherein each angle is between 75 and 105°. 6. The method as claimed in claim 1, wherein a closure plate is placed on the upper part and on the lower part, respectively, of the plate stack, and each closure plate is welded by a continuous sealed weld bead to the flange of the adjacent plate. 7. The method as claimed in claim 1, wherein each side face of the plate stack is partially closed by a covering plate. 8. The method as claimed in claim 2, wherein each side face of the plate stack is partially closed by a covering plate. 9. A plate pack for a heat exchanger, wherein plates superposed and assembled by the method according to any one of the preceding claims. 10. The plate pack as claimed in claim 9, wherein each plate has the shape of a quadrilateral comprising a central heat-exchange part and four borders with a smooth surface, each one fitted with a folded flange, the four folded flanges being directed alternately upward and downward. 11. The plate pack as claimed in claim 9, wherein a closure plate is placed on the upper part and on the lower part, respectively, of the plate stack, each closure plate being connected to the flange of the adjacent plate by a continuous scaled weld bead. 12. The plate pack as claimed in claim 9, wherein a covering plate is placed on each side face of the plate stack partially closing the corresponding side face. 13. The plate pack as claimed in claim 10, wherein a closure plate is placed on the upper part and on the lower part, respectively, of the plate stack, each closure plate being connected to the flange of the adjacent plate by a continuous scaled weld bead. 14. The plate pack as claimed in claim 10, wherein a covering plate is placed on each side face of the plate stack partially closing the corresponding side face. 15. The plate pack as claimed in claim 11, wherein a covering plate is placed on each side face of the plate stack partially closing the corresponding side face.
