Abstract: The present invention relates a tube for a heat exchanger. The tube includes at least one fusible part formed on at least one coupling edge of the tube for assembling with at least one wall of the heat exchanger. Further, the fusible part is parallelly aligned with respect to a general plane (P1) of the tube. The tube further includes a base portion located in the vicinity of the coupling edge and a tip portion defined in the vicinity of the wall of the heat exchanger. The tip portion of the fusible part is adapted to break by differential in expansion and contraction between the tube and the wall.

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).
