Claim 0:
1. An additive manufacturing method of making an entwined tubular arrangement for a heat exchanger, comprising:
using an additive manufacturing technique to build up one or more thermally conductive materials layer-by-layer from a Computer-Aided Design (CAD) model;
building a support structure and the entwined tubular arrangement out of the one or more thermally conductive materials, wherein the entwined tubular arrangement comprises first and second tubes wound around one another and in contact with one another; and
retaining the support structure after the entwined tubular arrangement has been built;
wherein the support structure comprises a lattice support structure, the lattice support structure at least partially filled with a thermally insulative material.
