Claim 19:
20. A method for transferring heat comprising the steps of:
a) providing a heat exchanger, said heat exchanger comprising:
i) one or more flexible carbon fiber sheets, each of the one or more flexible carbon fiber sheets having a first end and a second end and comprising a plurality of carbon fibers oriented in a direction extending from the first end to the second end, wherein the one or more flexible carbon fiber sheets are thermally anisotropic in the direction extending from the first end to the second end, wherein the one or more flexible carbon fiber sheets have a bend radius less than or equal to 10 inches, and
ii) a support structure comprising one or more holding regions, wherein the one or more flexible carbon fiber sheets are connected to the support structure at the one or more holding regions;

b) positioning the first ends of the one or more flexible carbon fiber sheets to be in thermal communication with a high temperature heat source, and the second ends of the one or more flexible carbon fiber sheets to be in thermal communication with a lower temperature source;
c) transferring heat between the high temperature heat source and the lower temperature source, wherein the first fluid and second fluid are, independently from one another, a liquid or a gas,
wherein the one or more flexible carbon fiber sheets are held in a flat form by fiberglass thread, and wherein the plurality of carbon fibers are held in place with the fiberglass thread such that the plurality of carbon fibers are oriented in a single direction extending from the first end of the flexible carbon fiber sheet to the second end of the carbon fiber sheet, and the fiberglass thread forms a cross-thread.
