ECHANGEUR DE CHALEUR, EN PARTICULIER POUR VEHICULE AUTOMOBILE, A LIAISON RIGIDE ENTRE UN FAISCEAU DE TUBES ET UN ENSEMBLE COLLECTEUR-BOITE A EAU

摘要

The invention relates to a heat exchanger including a bundle of tubes in which the ends of the tubes (32) in the bundle (30) are sealed in the holes through a perforated plate (36) to which a water box (42) is fixed. The water box and perforated plate assembly includes means (44) co-operating with the sides of the fins (34) of the tubes (32) to oppose displacement of the bundle relative to the perforated plate by pivoting or by torsion. The invention is particularly applicable to heat exchangers for motor vehicles.
