摘要

The exchanger has a beam for heat exchange between fluids. A molded fluid collecting box (23) is attached to the beam. A contact interface (29) is arranged between the collecting box and the beam, and includes a centering unit (37) that is arranged at an end of the interface. The interface presents a rectangular form, where the centering unit is arranged such that an angle is formed between a large lateral edge and a small lateral side of the interface. The collecting box and the beam are assembled with a gap having depth dimension lower than 0.5 mm.
