ABSTRACT:
A heat exchanger assembly such as a radiator, or the like, comprising a core having front and rear faces and including tubes parallel to the faces and spaced fins extending transversely to the faces and the tubes respectively and interconnecting the tubes by being soldered thereto. The core has an opening therein defined by a group of the tubes being devoid of a length thereof so as to have spaced first and second open ends. A single tank is in fluid communication with the first and second ends to establish fluid communication therebetween. The tank has front and rear walls disposed adjacent the front and rear faces of the core and a peripheral wall extending about the opening and interconnecting the front and rear walls to define an enclosed volume within the tank. A tubular member extends through the volume between the front and rear walls and in spaced relationship to the peripheral wall for defining a clearance hole allowing access through the core between the opposite faces. The assembly may include sheet-like fins or serpentine fins and a method for making all embodiments is disclosed.
