A cast heat exchanger, having an inlet and an outlet and defining an internal passage therebetween, includes a wall structure disposed within the internal passage that defines a series of interconnected chambers through which a cooling medium flows in a serpentine path. The outer surface of the heat exchanger is covered with pin fins that transfer heat away from the hot working medium flowing over the pin fins and into the cooling medium within the chambers of the heat exchanger.
