摘要

The present invention relates to a method of manufacture of a radiator (1) comprising a main body made of metal (2) in which is formed a sinuous groove (4) which is open over its entire length in a face (3) of the main body, this groove (4) being closed in sealed manner by a strip of flat metal plate (6) is cut out along a sinuous shape of the groove (4), each edge of this flat strip (6) being welded to a bank of the groove. The strip of sheet (6) is cut out in a sheet according to the sinuous shape with a method of cutting out by laser ray.
