A heat exchanger system includes a plurality of additively manufactured heat transfer surfaces in a plurality of sectors, a first of the plurality of sectors including a first subset of the plurality of the additively manufactured heat transfer surfaces having a characteristic different than a characteristic in a second of the plurality of sectors.

Heat exchanger system with spatially varied additively manufactured heat transfer surfaces

A heat exchanger assembly embodiment includes a plurality of laminated ceramic tape layers having at least one hole surrounded by at least one tape remainder portion. The plurality of layers is arranged in a build direction defined parallel to a counter-flow plane. Each laminated ceramic tape layer is stacked and sintered to define a ceramic core section integrally formed with a first ceramic manifold and a second ceramic manifold. The ceramic core section of the assembly includes a plurality of spaced apart counter-flow plates stacked along a stacking direction normal to the counter-flow plane and the build direction, defining a plurality of flow passages parallel to the counter-flow plane. Each flow passage is in communication with the first manifold and the second manifold. A plurality of counter-flow fins is disposed in at least one of the plurality of flow passages, between adjacent ones of the plurality of counter-flow plates.
