Photo cell with spaced anti-oxidation member on fluid loop
View Patent ↗A fluid tube routes a fluid adjacent to a source of heat to heat the fluid. The heated fluid is passed adjacent to cells which receive infrared radiation from the heated fluid. An anti-corrosion member is positioned on a portion of the tube adjacent to the cells. The anti-corrosion member is spaced from an outer periphery of the tube to provide a chamber between the portion of the tube and the anti-corrosion member.
1. A source of electricity comprising:
a source of heat;
a fluid tube for routing a fluid adjacent to the source of heat to heat the fluid, and for passing the heated fluid to be adjacent cells which receive infrared radiation from the heated fluid, and then returning the heated fluid through the tube to be adjacent to the source of heat; and
an anti-corrosion member positioned on at least a portion of the tube that is adjacent to the cells, said anti-corrosion member being spaced from an outer periphery of the tube to provide a chamber between the portion of the tube and the anti-corrosion member.
2. The source as set forth in claim 1 , wherein the anti-corrosion member has ends that close off the chamber, and an outer wall which has an inner periphery spaced from the outer periphery of the two to define the chamber.
3. The source as set forth in claim 2 , wherein the chamber is filled with an inert gas.
4. The source as set forth in claim 2 , wherein the chamber is mounted at a vacuum pressure.
5. The source as set forth in claim 1 , wherein the cells are thermophotovoltaic cells.
6. The source as set forth in claim 1 , wherein said anti-corrosion member is formed of one of yttrium aluminum garnet (YAG), aluminum oxynitride (AlON), and magnesium aluminate (spinel).
7. The source as set forth in claim 1 , wherein the source of heat is a nuclear reactor.
8. The source as set forth in claim 1 , wherein the source of heat is a solar receiver.
9. A fluid loop and infrared cell combination comprising:
a fluid tube for routing a fluid adjacent to a source of heat to heat the fluid, and for passing the heated fluid to be adjacent cells which receive infrared radiation from the heated fluid, and then returning the heated fluid through the tube to be adjacent to the source of heat; and
an anti-corrosion member positioned on at least a portion of the tube that is adjacent to the cells, said anti-corrosion member being spaced from an outer periphery of the tube to provide a chamber between the portion of the tube and the anti-corrosion member.
10. The combination as set forth in claim 9 , wherein the anti-corrosion member has ends that close off the chamber, and an outer wall which has an inner periphery spaced from the outer periphery of the two to define the chamber.
11. The combination as set forth in claim 10 , wherein the chamber is filled with an inert gas.
12. The combination as set forth in claim 10 , wherein the chamber is maintained at a vacuum pressure.
13. The combination as set forth in claim 9 , wherein the cells are thermophotovoltaic cells.
14. The combination as set forth in claim 9 , wherein said anti-corrosion member is formed of one of yttrium aluminum garnet (YAG), aluminum oxynitride (AlON), and magnesium aluminate (spinel).
15. The source as set forth in claim 2 , wherein said fluid tube enters said chamber at one end of said anti-corrosion member, and exits said chamber at an opposed end, such that said fluid tube extends beyond said chamber.
16. The combination as set forth in claim 10 , wherein said fluid tube enters said chamber at one end of said anti-corrosion member, and exits said chamber at an opposed end, such that said fluid tube extends beyond said chamber.
