(54) SEGMENTED FINS FOR A CAST HEAT EXCHANGER


(57) A heat exchanger (10) includes a plate portion (24) including a top surface (26), bottom surface (28), a leading edge (32), a trailing edge (32) and a plurality of internal passages (34) extending between an inlet (36) and an outlet (38). A plurality of fin portion rows (42) are included. A first row (48) of the plurality of fin portion rows (42) includes at least two discrete fin portions (46) and a second row (50, 52, 54) of the plurality of fin portion rows (42) includes fewer fin portions (56, 58, 40) than the first row (48). The first row (48) is closer to the inlet (36) than the second row (50, 52, 54). A cast plate (22) for a heat exchanger (10) and a method are also disclosed.
