CA 2286906

A method of producing a heat transfer device comprising a base (1) and a number of flanges (2) projecting from the base (1), the device being formed with the flanges in a first mutual relation in a first operation and the base being subjected to at least partial deformation in a second operation so that the flanges projecting from the deformed por:ion of the base are brought into a second mutual relation, the flanges being arranged at shorter mutual distances in the second relation than in the first relation.

L'invention concerne un procédé de fabrication d'un dispositif de transfert de chaleur comprenant une base (1) et plusieurs ailettes (2) saillant de la base (1) et mises dans une première position les unes par rapport aux autres dans une première opération et la base étant soumise à au moins une déformation partielle dans une deuxième opération de sorte que les ailettes saillant de la partie déformée de la base soient mises dans une deuxième position les unes par rapport aux autres. Les ailettes se trouvent à une distance plus courte les unes des autres dans la première position que dans la deuxième.
