A heat exchanger is provided for use in extracorporeal blood oxygenation systems. The heat exchanger includes a housing, a core disposed within the housing, and a baffle disposed within the core. A blood passage chamber is defined by the outer surface of the core and the inner surface of the housing. Blood flows from the blood inlet, through the blood passage chamber, to the blood outlet. Heat exchange fluids flow from a fluid inlet, into an inlet chamber, around the baffle, into an outlet chamber, and to a fluid outlet.
