9. A compact heat exchanger assembly, comprising:
a heat rejection heat exchanger assembly, comprising:
a primary heat exchanger, comprising:
a first tube bank extending from a first manifold,
a second tube bank extending from a second manifold,
at least one bend arranged to fluidly connect the first tube bank to the second tube bank, and
bends provided with the first tube bank and the second tube bank such that at least a portion of the first tube bank is disposed parallel to the second tube bank; and
a secondary heat exchanger disposed between the second manifold and the at least one bend;
wherein the primary heat exchanger and the secondary heat exchanger are arranged in a closed shape;
wherein a sealing member connects the secondary heat exchanger to the second manifold to seal between the primary heat exchanger and the secondary heat exchanger;
wherein the primary heat exchanger is U-shaped and the secondary heat exchanger extends across a width of the U-shape to define the closed shape.
