TUBE BANK HEAT EXCHANGER

A heat exchanger (20) has: a first manifold assembly (42) having a stack of plates (60, 62, 64, 66, 68, 70); a second manifold assembly (44) having a stack of plates (80, 82, 86, 88); and a plurality of tubes (46) extending from the first manifold assembly (42) to the second manifold assembly (44). The plurality of tubes (46) is a plurality of groups of tubes. For each of the groups of the tubes: the tubes (46) of the group have first ends mounted between plates (60, 62, 64, 66, 68, 70) of the first manifold assembly (42); and the tubes (46) of the group have second ends mounted between plates (80, 82, 86, 88) of the second manifold assembly (44).
