Abstract: A heat exchanger includes a plurality of interconnected separator members that respectively include a first surface and an opposite second surface. The separator members respectively include an array of wave features. Also, the separator members are stacked and disposed in an alternating arrangement with the first surfaces of adjacent separator members facing each other and attached at the respective wave features, and with the second surfaces of adjacent separator members facing each other and attached at the respective wave features. The heat exchanger also includes a plurality of first flow passages for first fluid flow and second flow passages for second fluid flow. The second fluid and the first fluid are configured to exchange heat through the separator members.

Abstract: A heat exchanger includes a separator member that divides a first flow passage from a second flow passage. The heat exchanger also includes a plurality of first hollow members that extend across the first flow passage at respective non-orthogonal angles. The plurality of first hollow members are fluidly connected to the second flow passage. Moreover, the heat exchanger includes a plurality of second hollow members that extend across the second flow passage at respective non-orthogonal angles. The plurality of second hollow members are fluidly connected to the first flow passage.
