Abstract

A heat exchanger assembly includes a plurality of first and second fluid passages defined by a pair of opposing first fluid passage walls and a plurality of first fluid diverters disposed between the first fluid passages walls. The second fluid passages are defined by a pair of opposing second fluid passage walls and a plurality of second fluid diverters disposed between the second fluid passage walls. An ejector is integrated into the heat exchanger assembly. The ejector includes: an integral ejector passage, wherein the integral ejector passage is a first fluid passage; a primary inlet configured to receive a hot fluid; an outlet nozzle configured to eject the hot fluid; a secondary inlet configured to receive a cold fluid, wherein the secondary inlet is in fluid communication with a second fluid passage; and a mixing section in fluid communication with the outlet nozzle and the secondary inlet.
