Abstract
A core arrangement for a heat exchanger includes a first core layer disposed along a first plane and having an inlet and outlet oriented along a first axis within the first plane and a first core stage disposed in fluid communication between the inlet and the outlet. The first core stage includes a first upstream fluid intersection downstream of and adjacent the inlet and having a first inlet continuation and a first bifurcation. The first core stage further includes a first downstream fluid intersection upstream of and adjacent the outlet and having a first outlet continuation and a first recombination. A plurality of first core tubes fluidly connect the first bifurcation to the first recombination. The first core layer further includes a second core stage disposed in fluid communication between the first inlet continuation and the first outlet continuation. The second core stage includes a second upstream fluid intersection downstream of the first inlet continuation and having a second bifurcation, and a second downstream fluid intersection upstream of the first outlet continuation and having a second recombination. A plurality of independent second core tubes fluidly connect the…
