Abstract: An aluminum tube-and-fin assembly for easy insertion into a manifold seal is provided. The assembly comprises a generally cylindrical, elongated tube and fins extending radially outward from the body. A bead is formed circumferentially around the tube end. A smooth, curved, circumferentially disposed bead corner is interposed between the bead and the tube end. The bead corner has a frustoconical curved shape and a radii of curvature of at least 0.2 mm.

Abstract: A grommet for insertion into an opening of a radiator header plate may have a cylindrical outer surface having a body outer diameter, an annular shoulder proximate a top surface and extending outwardly beyond the outer surface of the body, and an annular bead proximate a bottom surface of the body and extending outwardly beyond the outer surface of the body and have a bead outer diameter that is greater than the body outer diameter. The annular bead may include a tapered bottom portion having a decreasing outer diameter as the tapered bottom portion extends downwardly toward the bottom surface of the body, with the tapered bottom portion terminating with a bottom outer diameter that is less than the body outer diameter.

Abstract: A heat exchanger with a first manifold and a second manifold. The heat exchanger includes tubes having first and second ends. The tubes connect to the first manifold at the first end and the second manifold at the second end establishing fluid communication between the manifolds. The tubes are arranged parallel and forming gaps between tubes. The heat exchanger includes fin matrices formed from fins that span the gaps and extend from the first end to the second end. At least two adjacent tubes define an expansion gap that accommodates thermal expansion.
