Abstract
An automotive radiator has an integrated air-liquid cooled oil cooler incorporated directly into the radiator core and header tanks. A pair of nested oil cooler tubes, nested in a general U shape, has parallel upper and lower lengths running through the top and bottom of the basic core, spaced within the same header plates as the standard coolant tubes. Intermediate parallel lengths of the oil cooler tubes run through the center lengthwise of one longer header tank. A shorter header tank allows the upper and lower lengths of the oil cooler tubes to run through its header plate with clearance from its tank ends.
