A METHOD FOR PRODUCING A CHANNEL ARRANGEMENT, A CHANNEL ARRANGEMENT, USE OF A CHANNEL ARRANGEMENT AND A METAL PROFILE

摘要

A method for producing a channel arrangement (28), a channel arrangement, a metal profile (1, 1a, 1b) and use of a channel arrangement. The method comprises a) arranging a first metal profile (1a) towards a second metal profile (1 b); said first profile (1a) comprises elongated trench-like portions (3) mutually separated by flat portions (5), b) joining the first profile to the second profile so that channels (22a, 22b) between these profiles are defined, said channels being separated by flat regions (21). In step a) as at least one of said profiles a profile comprising an incipient cut (10a1 10b, 10c) to be located in at least one said flat region. The method further comprises c) removing material (26) from said at least one flat region so that the thickness of a part of said at least one flat region becomes less than the sum of the thicknesses of the profiles.
