Abstract: An additively manufactured heat exchanger configured to transfer heat between a first fluid and a second fluid includes a first channel with a first wall configured to port flow of a first fluid and a second channel with a second wall configured to port flow of a second fluid. The heat exchanger also includes a barrier channel containing unprocessed build powder provided by the additive manufacturing process and is located between the first wall and the second wall. The barrier channel is configured to prevent mixing of the first fluid and the second fluid when one of the first wall and the second wall ruptures.

Abstract: A heat exchanging arrangement includes a first flow circuit for a first fluid to be cooled, which has a first inlet, a first outlet, and a second outlet. The heat exchanging arrangement includes a second flow circuit for a second fluid, which is in thermal communication with the first flow circuit. The heat exchanging arrangement includes a third flow circuit configured to port a portion of the first fluid from a first location of the first flow circuit to a second location of the first flow circuit, the first location being downstream of the second location.

Abstract: A closure bar adapted for use in a heat exchanger core includes a center void region configured to be partially filled with a phase-changing material and sealed, thereby containing the phase-changing material. The phase-changing material is configured to change phase in a forward direction as the flow of hot fluid over the closure bar begins, thereby slowing a rate of a temperature increase by absorbing a latent heat as the phase-changing material changes phase in the forward direction, and change phase in a reverse direction as the flow of hot fluid over the closure bar ceases, thereby slowing a rate of a temperature decrease by liberating the latent heat as the phase-changing material changes phase in the reverse direction. A method of producing and using the closure bar is also disclosed.

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.
