Abstract:
A radiator comprising:a radiator core defining a front and a rear face thereof and including a plurality of generally rectangular shaped tubes interleaved with layers of fins for passage of air through said core; and a collecting tank attached to said core in a fluid tight manner to provide fluid communication between said tubes and said collecting tank; said tubes each having a pair of side walls extending through said core and joined by end walls at said front and rear face of said core; said tubes each terminating at one end thereof in a formed segment wherein said end walls of each tube are bifurcated for a distance from said one end of the tube to define planar portions disposed substantially normal to said side walls and one of said side walls is adapted to contact a side wall of an adjacent tube in the core; said adapted side wall being joined in a fluid tight manner to said contacted side wall of said adjacent tube; said collecting tank having walls thereof extending over said front and rear faces of said core past said bifurcation of said end walls in substantial surface to surface with said planar portions and joined in a fluid tight manner to said end walls and said planar portions of said tubes along and beyond said bifurcation to thereby form a fluid tight joint between said walls of said collecting tank and said end walls of said tubes.
