Heat conduction systems

摘要

A heat conduction system including modular pipes housing a solid heat conductor made of a combination of carbon foam glass and grapheme and, for conductors, insulated from the outermost pipe by an insulating layer and with an annular gas purging gap for high-temperature applications. Also included in the system are thermal valves, manifolds, and heat exchangers to route and use the thermal energy. In an exemplary use, a down-hole heat exchanger, thermally coupled to a string of heat conduction modules, brings geothermal heat up from abandoned oil wells to operate a boiler and steam turbine. In another exemplary use, waste heat is conducted out of slag for conversion into useful energy. In yet another exemplary use, waste heat is conducted away from a nuclear reactor.

主权项

1. A heat conduction system comprising:
a. a solid heat conducting core material comprising an ultrasonically blended and subsequently pyrolyzed combination of pitch, coal tar, and graphene and having first and second core ends; and b. an outer casing having first and second casing ends enclosing said heat conducting core material, wherein said casing provides thermal conduction access to at least said first and second core ends; c. wherein:
i. said outer casing comprises a thermal valve casing having:
1. thermal valve input and output channels;2. a housing having an upper chamber and a lower chamber; and3. couplings at distal ends of said input and output channels, operable to couple to other elements of said heat conduction system;ii. said housing houses a moveable disc operable to be controllably moved within said upper and lower chambers, wherein said disc comprises a plurality of apertures of various sizes, each operable to be selectively aligned to said input and output channels via said controlled movement of said disc; andiii. said solid heat conducting core material:
1. extends through each aperture of said plurality of apertures; and2. extends within said thermal valve input and output channels.
