Abstract
A counterflow heat transfer system comprises a heat exchanger and a flow controller arranged to convey a first fluid through the heat exchanger in a first flow direction and a second fluid through the heat exchanger in a second counterflow direction. The heat exchanger comprises at least one first thermally conductive tube conveying the first fluid and at least one second thermally conductive tube conveying the second fluid. The first and second tubes are wound around one another and in contact with one another in an entwined tubular arrangement.
Claims10
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.
