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.
Claims11
A heat transfer system comprising a heat exchanger conveying 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 second fluid having a different temperature to the first fluid, the heat exchanger comprising:
- at least one first thermally conductive tube conveying the first fluid;
- at least one second thermally conductive tube conveying the second fluid;
- wherein the first and second thermally conductive tubes are wound around one another and in contact with one another in an entwined tubular arrangement;
- wherein the entwined tubular arrangement is supported by a support structure made of the same thermally conductive material as the first and second thermally conductive tubes;
- and
- wherein the support structure comprises a lattice support structure.
An entwined tubular arrangement for a heat exchanger, the arrangement comprising:
- at least one first thermally conductive tube for conveying a first fluid;
- at least one second thermally conductive tube for conveying a second fluid;
- wherein the first and second tubes are wound around one another and in contact with one another in an entwined tubular arrangement;
- wherein the entwined tubular arrangement is supported by a lattice support structure made of the same thermally conductive material as the first and second tubes;
- and
- wherein the lattice support structure is at least partially filled with a thermally insulative material.
