Abstract (en)
[origin: EP2306134A1] The method involves forming clamped folds (3) forming fins, on a first flat or corrugated sheet (2), and opening the clamped folds on a part of their length. The first sheet is placed on a second flat or corrugated sheet (6) or a part of the first sheet is folded on another part of the first sheet. A clamped part of the folds is soldered and the first sheet is soldered on the second sheet or the former part is soldered on the latter part. A third flat or corrugated sheet (7) is placed and soldered under the second sheet, where the second and third sheets constitute sheets in lower position.
