US Patent:

44741707, Oct 2, 1984

Filed:

Aug 6, 1981

Appl. No.:

6/290282

Inventors:

Robert D. McConnell - Lakewood CO
James H. Vansant - Tracy CA

Assignee:

Department of Energy - Washington DC

International Classification:

F24J 302

US Classification:

126433

Abstract:

A glass heat pipe is adapted for use as a solar energy absorber in an evacuated tube solar collector and for transferring the absorbed solar energy to a working fluid medium or heat sink for storage or practical use. A capillary wick is formed of granular glass particles fused together by heat on the inside surface of the heat pipe with a water glass binder solution to enhance capillary drive distribution of the thermal transfer fluid in the heat pipe throughout the entire inside surface of the evaporator portion of the heat pipe. Selective coatings are used on the heat pipe surface to maximize solar absorption and minimize energy radiation, and the glass wick can alternatively be fabricated with granular particles of black glass or obsidian.

Abstract:

A superconducting conductor assembly using high temperature materials. A double-walled tubular structure has at least one helical strip of superconductive material on the inner wall of the inside tube. Brittle, non-ductile superconducting materials may be used. A coolant, typically liquid nitrogen, is circulated between the tubes to maintain the superconductor below the critical temperature of the superconductor. A buffer layer is preferably included between tube wall and superconductor. A plurality of alternating layers of buffer and superconductor may be used.
