Abstract: A method of manufacturing a vehicle radiator including joining the liquid conducting tubes to the tank headers by punching holes with upstanding collars in the headers and inserting a tube end in each collar, each collar to tubing joint being formed by welding an intermediate portion of the joint and filling the rest with solder thereby forming a composite joint of weld and solder with additional solder forming a fillet behind the weld.

Abstract: A heat exchanger in which a header and tank construction comprises separate header and tank portions which are used in combination to form a heat exchanger unit. End caps for the header and tank construction and baffles to form partitions or chambers within the header and tank construction are inserted in grooves formed in the separate header and/or tank portion(s). The heat exchanger assembly comprises spaced combined header and tank constructions between which extend a plurality of tubes which are inserted in slots in the header portions. An area of the header portion can have a plurality of center portions and slots between adjacent center portions for the tubular elements. The apexes of each center portion between the tubular element slots have a flattened area and there are side portions running downward from the center portion apex flats which also are substantially flattened.
Abstract: A heat exchanger assembly which comprises spaced tubular header and tank constructions between which a plurality of tubular elements whose open ends are inserted in slots in the header surface or tube member receiving portions. The header surface or tube member receiving portion has a plurality of center elements. The apexes of each center portion between the tubular element slots have a flattened area and there are side portions running downward from the center portion apex flats which also are substantially flattened.
Abstract: An improved ram air charge heat exchanger ducting system, is disclosed comprising an elongated, hollow header tank, having a generally rectangular opening therein for engagement to a header sheet of a heat exchanger core. The hollow header tank is of increasing depth from a closed end to an outlet end, and the outlet comprises an attachment ridge having a mounting surface arranged in a plane at an angle to the plane of the header mounting surface. A duct inlet has a mounting surface configured to generally mate with the mounting surface of the header outlet and, means are provided to removably attach the duct to the header outlet. This system allows variety in attachment for multiple automotive environments.
