Abstract: A heat exchanger for exchanging heat between a first fluid and a second fluid is disclosed in accordance with an embodiment of the present invention. The heat exchanger includes a first manifold, a second manifold, a bundle of heat exchange elements and a housing. The bundle of heat exchange elements for the first fluid axially extend and provide a fluidal communication between the manifolds. The housing for the second fluid encapsulates at least part of the heat exchange elements to form a fluid tight channel for the second fluid. The housing further includes at least one sacrificial component being of material having lower galvanic potential than the remaining components.

Abstract: The main object of the invention is a heat exchanger including a first header plate of an inlet manifold, a second header plate of a distribution header and a heat exchange core bundle extending between the first header plate and the second header plate along a longitudinal direction, the heat exchange core bundle being defined by a shell and having a plurality of tubes arranged successively next to each other in a transverse direction, each tube being capable of cooperating with the header plates via through-holes formed in each plate. The shell has at least one longitudinal end with a straight edge configured to be in flat surface contact with at least one header plate in a contact area, the surface contact occurring mainly in a plane perpendicular to the longitudinal direction.

Abstract: The present invention relates to a heat exchanger (1) comprising at least one heat exchange bundle (2), a box (4, 6) and a collector (8), the box (4, 6) being arranged at one end (24, 26) of the heat exchange bundle (2), the heat exchange bundle (2) comprising at least one peripheral wall (10) which delimits a housing (18) in which a plurality of tubes (12) extend, inside which tubes a first fluid circulates and around which a second fluid circulates, at least one opening (30) being provided in the peripheral wall (10) and a collector (8) comprising a peripheral edge (40) being arranged so as to cover the opening (30).
