Claim 0:
1. A turbine engine comprising:
a heat exchanger comprising:
an inlet manifold having:
at least one inlet; and
a plurality of outlets;

an outlet manifold having:
at least one outlet; and
a plurality of inlets; and

a plurality of tube banks, each tube bank coupling one of the inlet manifold outlets to an associated one of the outlet manifold inlets, each of the tube banks partially nesting with one or more others of the tube banks,

a gas path passing combustion gas across exteriors of the tube banks,, wherein each of the tube banks comprises:
a first header coupled to the associated inlet manifold outlet and the associated outlet manifold inlet;
a second header; and
a plurality of tube bundles each having a first end coupled to the associated first header and a second end coupled to the associated second header, with a flowpath from the associated inlet manifold outlet passing sequentially through flowpath legs formed by each of the tube bundles in the associated tube bank to exit the tube bank to the associated outlet manifold inlet.
