| 摘要 |
The present invention relates to a method for realizing a radiator element (1) comprising: a first plastic deformation of the ends of a pipe, do as to obtain a shoulder on each end; the introduction of the ends of said pipe (2) into special holes obtained into the wall of a manifold, holes exhibiting an abutment complimentary to the shoulder; a second plastic deformation of the pipe end, do as to obtain the mechanical locking of the pipe itself relative to the manifold (3). The invention also relates to the machinery for performing the described method, the resulting radiator element and the radiator. |
