Abstract: A fin characterized by a corrugated shape and configured to be interposed between adjacent instances of tubes of a heat exchanger assembly includes a plurality of planar portions, a radiused portion, and a retention feature. The plurality of planar portions is configured to extend between the adjacent instances of the tubes. The radiused portion is located between adjacent planar portions and is configured to be in thermal contact with a tube proximate thereto. The retention feature is located substantially mid-way between a leading edge and a trailing edge of the fin. The retention feature is configured to contact the tube in a manner effective to prevent fall-out of the fin prior to brazing of the heat exchanger assembly.

Abstract: An automotive condenser (10) includes spaced manifold assemblies (18) comprised of semicylindrical tanks (20), matching semicylindrical headers (22) and simple, circular disks (38) serving as manifold separators. The disks (38) are sandwiched between the tank (20) and header (22) with no need for orientation, and with no slots or through notches to pierce the surface of the tank (20) or header (22). The disks (38) sit within matching pairs of common diameter grooves (30, 36) which provide complete, continuous pockets therefore.
