Abstract
A heat exchanger for heat exchange between a first fluid and a second fluid has a plurality of tube sections, each comprising; an interior for passing the first fluid; an exterior for exposure to the second fluid; a first leg; a second leg; a turn joining the first leg to the second leg; and a first face and a second face. A support has at least one carbon member engaging the plurality of tube sections.
Claims25
A heat exchanger for heat exchange between a first fluid and a second fluid and comprising:
- a plurality of tube sections, each comprising:
- an interior for passing the first fluid;
- an exterior for exposure to the second fluid;
- a first leg;
- a second leg;
- a turn joining the first leg to the second leg;
- and
- a first face and a second face;
- a manifold, wherein the first leg and second leg of each of the tube sections are mounted to the manifold and in communication therewith;
- and
- a support spaced from the manifold and comprising:
- at least one carbon member engaging the plurality of tube sections,
- wherein:
- the plurality of tube sections are positioned in a plurality of stages from upstream to downstream along a flowpath of the second fluid;
- and
- the at least one carbon member comprises a plurality of carbon members in at least one stack from upstream to downstream along the flowpath of the second fluid.

A turbine engine comprising:
- one or more compressor sections;
- a combustor section;
- one or more turbine sections;
- a gas path passing through the one or more compressor sections, the combustor section, and the one or more turbine sections;
- and
- a recuperator,
- wherein the recuperator comprises:
- a heat exchanger for heat exchange between a first fluid and a second fluid and wherein the first fluid is a working fluid of the recuperator and the second fluid is combustion gas downstream of the one or more turbine sections, the heat exchanger comprising:
- a plurality of tube sections, each comprising:
- an interior for passing the first fluid;
- an exterior for exposure to the second fluid, the gas path passing gas across exteriors of the plurality of tube sections;
- a first leg;
- a second leg;
- a turn joining the first leg to the second leg;
- and
- a first face and a second face;
- and
- a support comprising:
- at least one carbon member engaging the plurality of tube sections.
