Abstract
A method is disclosed for producing a heat exchanger, in particular for a motor vehicle, a method whereby fluid circulation tubes () are inserted into through holes in heat exchange fins () and the fluid circulation tubes () are subjected to expansion in such a way as to expand a contour () of the tubes () to ensure contact with the fins () at the through holes and, additionally, for at least one of the tubes (), to deform a concave portion () of the contour () of the tube or tubes (), in such a way as to correspondingly deform the through holes. A device for implementing the method and an exchanger obtained by the method are also disclosed.
