A heat exchanger assembly (10) includes a plurality of first (14) and second (22) fluid passages defined by a pair of opposing first fluid passage walls (16) and a plurality of first fluid diverters (18) disposed between the first fluid passages walls (16). The second fluid passages (22) are defined by a pair of opposing second fluid passage walls (22) and a plurality of second fluid diverters (24) disposed between the second fluid passage walls (22). An ejector (26) is integrated into the heat exchanger assembly (10). The ejector (26) includes: an integral ejector passage (28), wherein the integral ejector passage (28) is a first fluid passage; a primary inlet (30) configured to receive a hot fluid; an outlet nozzle (32) configured to eject the hot fluid; a secondary inlet (34) configured to receive a cold fluid, wherein the secondary inlet (34) is in fluid communication with a second fluid passage (20); and a mixing section (36) in fluid communication with the outlet nozzle (32) and the secondary inlet (34).
