1. A unitary, 3D-printed, single-piece heat exchanger, the heat exchanger comprising:
a main body defining an inlet port and an outlet port 3D-printed with the main body;
a plurality of plates in a stacked arrangement and 3D-printed with the main body, the plurality of plates printed to be interposed between fluid channels, the plurality of plates including an upper-most plate, wherein no other plates exist above the upper-most plate;
a first inlet manifold 3D-printed with the main body, the first inlet manifold fluidly coupled to the inlet port and enabling a fluid to enter the fluid channels;
a first outlet manifold 3D-printed with the main body, the first outlet manifold fluidly coupled to the outlet port and enabling the fluid to exit the fluid channels;
a jumper pipe 3D-printed with the main body and fluidly coupling the inlet port to the first inlet manifold, wherein the jumper pipe extends across the upper-most plate and is printed integrally with the upper-most plate; and
a second inlet manifold and a second outlet manifold with the main body, wherein the second outlet manifold is located at an opposing end of the heat exchanger from the second inlet manifold, and wherein the second outlet manifold is adjacent the first inlet manifold;
wherein each of the first inlet manifold, the first outlet manifold, the second inlet manifold, and the second outlet manifold are located in different quadrants of the heat exchanger to enable a hybrid counter cross flow;
wherein the main body, the plurality of plates, the first inlet manifold, the second inlet manifold, the first outlet manifold, the second outlet manifold, and the jumper pipe are all 3D-printed components 3D-printed as a single monolithic unit; and
wherein a lower surface of the jumper pipe is an upper surface of the upper-most plate.
