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.

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

A collection box with an integrated reservoir for a heat exchanger, has a cylindrical tubular wall and a separation wall, disposed inside the tubular wall to delimit a collection compartment and a reservoir compartment. The tubular wall is equipped with spaced holes to receive the ends of tubes of a bundle of tubes. The separation wall comprises a central core prolonged on either side by a first edge region and by a second edge region having profiles each designed and suitable to be applied and soldered against the inside of the tubular wall.
