Claim 0:
1. A heat exchanger comprising:
a first manifold assembly comprising a stack of plates;
a second manifold assembly comprising a stack of plates; and
a plurality of tubes extending from the first manifold assembly to the second manifold assembly,, wherein:
the plurality of tubes comprises a plurality of groups of tubes; and
for each of the groups of the tubes:
the tubes of the group have first ends mounted between plates of the first manifold assembly; and
the tubes of the group have second ends mounted between plates of the second manifold assembly;

the first manifold assembly is an inner manifold assembly; and
the second manifold assembly is an outer manifold assembly at least partially surrounding the inner manifold assembly so that the tubes of each group diverge from each other from the first manifold assembly to the second manifold assembly.
