Abstract:
An automotive radiator with integrated liquid-air oil cooler, comprising,a pair of spaced, regularly slotted header plates,a plurality of air cooled, engine coolant tubes extending between said header plates, generally perpendicular thereto, the ends of which are located in all but at least the lowermost and uppermost slot in each header plate and sealed liquid tight to said header plates,a continuous oil cooler tube bent into a general U shape having an upper length extending through each uppermost slot in each header plate and parallel to a coolant tube, an intermediate length extending generally parallel to one header plate, and a lower length extending through each lowermost slot in each header plate and parallel to a coolant tube, said oil cooler tube being sealed liquid tight to at least said one header plate,a first tank body sealed liquid tight to said one header plate and sufficiently long to cover all of the slots therein as well as the intermediate length of said oil cooler tube,a second tank body sealed liquid tight to the other of said header plates and sufficiently long to only cover all but at least the uppermost and lowermost slot therein, so as to form, with said header plates, a pair of spaced header tanks to feed engine coolant into and out of said engine coolant tubes, and,fittings on the ends of said oil cooler tube upper and lower lengths to feed oil into and out of said oil cooler tube,whereby, oil running through said oil cooler tube will be air cooled in the upper and lower lengths thereof, as well as liquid cooled in the intermediate length thereof located within said first header tank, with no internal leak path from said oil cooler tube within said first header tank.
