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: A header (10) for a heat exchanger, in particular for a charge air cooler, comprising an opening plane (12) with plurality of openings (14) for attachment of tubes, a collar (13) encircling the perimeter of the opening plane (12) and protruding at least partially above the opening plane (12), wherein the header (10) further comprises guiding protrusions (11a, 11b) located along inner perimeter of the collar (13) adjacent to said openings (14) and configured to guide the tubes into the openings (14) upon insertion, wherein the openings (14) have substantially rectangular shape with longer sides (14a) and shorter sides (14b) and are arranged in series along their longer sides (14a), wherein a first group of guiding protrusions (11a) is located adjacent the longer sides (14a) of the openings (14), while a second group of guiding protrusions (11b) is located adjacent the shorter sides (14b) of the openings (14).
