Heat exchanger with integral bleed air ejector

A method of making a heat exchanger assembly comprising:

• forming a plurality of opposing first fluid passage walls and a plurality of first fluid diverters disposed between the first fluid passage walls;
• wherein the plurality of first fluid passage walls and the plurality of first fluid diverters define a plurality of first fluid passages, each of the plurality of first fluid passages extending in a first direction from a first fluid inlet end to a first fluid outlet end;
• forming a pair of opposing second fluid passage walls and a plurality of second fluid diverters disposed between the second fluid passage walls;
• wherein the plurality of second fluid passage walls and the plurality of second fluid diverters define a plurality of second fluid passages;
• integrating an ejector into the heat exchanger assembly, the ejector comprising:
• an integral ejector passage extending in the first direction from the first fluid inlet end to the first fluid outlet end, wherein the integral ejector passage is a first fluid passage, and wherein the integral ejector passage comprises:
• a primary inlet located at the first fluid inlet end and configured to receive a hot fluid;
• and
• 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 of the integral ejector passage and the secondary inlet.
