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: 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.
