Abstract: A heat exchanger, such as a radiator, may transfer heat from a liquid and employ a first header tank, a second header tank, a plurality of tubes fluidly joining the first and second header tanks, and a baffle within one of the first or second header tanks. The baffle may be located in a header tank positioned substantially parallel or perpendicular to a surface upon which a vehicle employing the hear exchanger rests. The baffle may be a wall defining only one slot, a wall defining only one slot that is open through one side of the wall, a wall that defines a plurality of slots, or a wall that defines a plurality of holes. The heat exchanger may further employ fluidly isolated first and second tube and fin sections each defining a self-contained flow path for cooling different liquids. The baffle may slow coolant flow in a flow path.
