Title: Method for fixing transverse partitions in the tubular fluid box of a heat exchanger

Abstract: The partitions are inserted through an open end of the cylindrical tubular wall of the fluid box, positioned and immobilised by means of deformations in the tubular wall, before the tubes are inserted and the assembly is soldered in a fluidtight manner. According to the invention, the deformations are localised on the outside of the region of the perimeter of the tubular wall on which the passage openings for the tubes extend, so as not to affect these openings. The method may be used in a condenser for a motor vehicle air conditioning unit.
