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.

Abstract: A heat exchanger includes a first fluid manifold extending along a first fluid axis from a first fluid inlet to a first fluid outlet. The first fluid manifold includes a first fluid inlet header, a first fluid outlet header, and a nested helical core section. The first fluid inlet header is disposed to fork the first fluid inlet into a plurality of first fluid branches distributed circumferentially and radially about the first fluid axis. The first fluid outlet header is disposed to combine the plurality of first fluid branches into the first fluid outlet. The nested helical core section fluidly connects the first fluid inlet header to the first fluid outlet header via a plurality of nested helical tubes, and includes radially inner and outer groups of circumferentially distributed helical tubes.
