Abstract
A corrugated flexible thin copper tube filled with sodium has a resilient flexible core along the axis thereof so arranged that it will contract and expand to take up the force of thermal expansion and contraction of the sodium. Since the coefficients of expansion of the sodium and copper are different, the absorption of this differential in force by the core prevents rupture of the copper tube and the formation of voids and hot spots within the copper tube.
Claims11
A conductor having an outer longitudinal relatively thin electrically conductive casing and an interior electrically conductive metal in said casing in electrically conductive contact therewith;
- the said interior electrically conductive metal having a different coefficient of thermal expansion than the outer relatively thin conductive casing;
- a core member substantially axially positioned along the interior of said outer casing;
- said interior electrically conductive metal filling the space between said outer electrically conductive casing and said core member;
- said core member being radially flexible and resilient;
- said core member being resiliently compressed when said interior metal expands;
- said core member expanding when said interior metal contracts;
- said core member remaining in contact with said interior metal, preventing the occurrence of voids in said interior metal between said interior metal and said core member and between said interior metal and said casing while absorbing pressures that may be generated by the difference in coefficient of expansion of the interior metal and said casing.
