Patent ID: 7516779

Claim:
A radiator and oil cooler combination for an internal combustion engine comprising: an outlet radiator tank having an engine coolant outlet at an end thereof, the radiator tank being connected along a side thereof to radiator core tubes, openings of the tubes extending along a length of the outlet radiator tank side, the radiator tank permitting coolant flow entering from the radiator core tubes to pass through the coolant outlet; an oil cooler within the outlet radiator tank and away from the engine coolant outlet comprising inner and outer concentric tubes sealed to each other at opposite ends thereof, one end of the oil cooler being closer to the engine coolant outlet than the other end of the oil cooler, with fluid connections through the outer concentric tube to allow oil to enter and exit the oil cooler, whereby oil may flow in the oil cooler between the inner and outer tubes, and the coolant may flow along an outer wall of the outer tube and through the inside of the inner concentric tube along an inner wall thereof; and a baffle located in the outlet radiator tank near the end the end of the oil cooler closer to the engine coolant outlet, the baffle being between the engine coolant outlet and the end of the oil cooler farther from the engine coolant outlet, the baffle having an opening spaced from the oil cooler outer wall whereby the spacing between the baffle opening and the outer wall restricts coolant flow therethrough so as to permit a portion of the coolant entering from the radiator core tubes to pass between the oil cooler and the opening and out the coolant outlet while forcing the other portion of the coolant entering from the radiator core tubes to flow away from the baffle opening, along the oil cooler outer wall and through the inside of the inner concentric tube along the inner wall and out the baffle opening and coolant outlet.
