A low profile, split flow charge air cooler with uniform flow exit manifold comprises a first heat exchanger core having a plurality of gas flow passages and a plurality of coolant flow passages arranged in alternating order. First and second gas outlet manifolds are in communication with the gas flow passages, and a gas inlet manifold is in communication with both the first and second gas outlet manifolds. The gas inlet manifold is located between the first and second gas outlet manifolds, such that the gas flows in two different directions from the inlet manifold toward the outlet manifolds. A gas outlet chamber receives the gas flows from the gas outlet manifolds and provides a space in which the gas flows are combined before being discharged from the heat exchanger.
