1. A cross corrugated fill pack assembly for cooling a fluid flowing through the pack with a gas flowing through the pack in a substantially opposing direction, the fill pack assembly comprising:
a first sheet defining a longitudinal axis and having a first end, a second end and a first plurality of flutes extending from the first end toward the second end, the first plurality of flutes being connected to each other laterally along the longitudinal axis, a first microstructure defined on the first sheet including first top flat strips, first bottom flat strips and first conduit sides connecting the first top flat strips to the first bottom flat strips, a plurality of first arcuate surfaces connecting the first top flat strips to the first conduit sides and the first bottom flat strips to the first conduit sides, the first conduit sides comprised of first inflection lines between the plurality of first arcuate surfaces, the first plurality of flutes extending at a first flute angle relative to the longitudinal axis, the first flute angle being approximately zero to forty-five degrees, the first plurality of flutes including a first flute; and
a second sheet having a second plurality of flutes including a second flute, a second microstructure defined on the second sheet including second top flat strips, second bottom flat strips and second conduit sides connecting the second top flat strips to the second bottom flat strips, a plurality of second arcuate surfaces connecting the second top flat strips to the second conduit sides and second bottom flat strips to the second conduit sides, the first and second microstructure extending substantially perpendicular to the longitudinal axis, the first sheet connected to the second sheet in an assembled configuration with the first plurality of flutes extending to an opposite side of the longitudinal axis relative to the second plurality of flutes in the assembled configuration such that the first flute crosses the second flute between the first and second ends, the first and second plurality of flutes guiding the gas flowing from the first end toward the second end.
