Abstract

A support form defining a longitudinal axis is provided. The support form includes a first section, a second substantially solid section, and at least one flow feature form. The first section includes a plurality of unit cells of a first material joined together to form a lattice. The second section includes a second material and surrounds the first section. The at least one flow feature form is defined in the second section and is configured to generate a flow feature on a heat exchanger tube formed by plating the support form.
