Panel assembly for a space-based power generation system
View Patent ↗An example space-based power generation panel arrangement includes a first reflective panel and at least one heat pipe configured to communicate thermal energy to the first reflective panel and a second reflective panel. The heat pipe is configured to hinge the first reflective panel to the second reflective panel.
1. A space-based solar focusing panel arrangement comprising:
a first reflective panel; and
at least one heat pipe configured to communicate thermal energy to the first reflective panel and a second reflective panel, wherein the heat pipe is configured to hingeably secures the first reflective panel to the second reflective panel wherein the first reflective panel is hingeably moveable relative to the second reflective panel between a first position and a second position, the first reflective panel aligned with the second reflective panel in the first position, and also wherein the first reflective panel and the second reflective panel each establish laterally extending planes, and the first reflective panel and the second reflective panel are in the same plane when the first reflective panel is in the first position,
a secondary reflector, wherein the plurality of reflective panels are aligned with the secondary reflector and spaced therefrom when the plurality of reflective panels are in the deployed position, and said secondary reflector is aligned with a centrally located power generation means.
2. The arrangement of claim 1 wherein the first reflective panel is stacked on top of the second reflective panel when the first reflective panel is in the second position.
3. The arrangement of claim 1 wherein the at least one heat pipe comprises a flex hose portion.
4. The arrangement of claim 1 wherein the first reflective panel comprises a base portion, the at least one heat pipe secured relative to a first side of the base portion and a reflector surface secured relative to an opposite side of the base portion.
5. The arrangement of claim 4 wherein the base portion comprises a graphite-epoxy material.
6. The arrangement of claim 4 the reflector surface comprises a Fresnel reflector.
7. The arrangement of claim 4 wherein the first panel is hingeably moveable relative to the second panel to a stowed position.
8. The arrangement of claim 1 , wherein the first and second reflective panels are both planar.
9. The arrangement of claim 8 , wherein the first and second reflective panels are moveable between deployed and stowed positions, and planes defined by the first and second reflective panels are in aligned when the first and second reflective panels are in the deployed and stowed positions.
10. The arrangement of claim 1 , including a third reflective panel hingeably secured to the second reflective panel, wherein the first reflective panel pivots relative to the second reflective panel about a first axis, and the third reflective panel pivots relative to the second reflective panel about a second axis that is generally perpendicular to the first axis.
11. A space-based solar focusing panel assembly comprising:
a plurality of reflective panels;
a cold plate; and
a plurality of conduits configured to communicate thermal energy between one of the plurality of reflective panels to another of the plurality of reflective panels and the plate, wherein some of the plurality of conduits hingeably connect the plurality of reflective panels wherein the plurality of reflective panels are hingeably moveable between a stowed position and a deployed position, wherein the reflective panels are aligned within the same plane in the deployed position;
a secondary reflector, wherein the plurality of reflective panels are aligned with the secondary reflector and spaced therefrom when the plurality of reflective panels are in the deployed position, and said secondary reflector is aligned with a centrally located power generation means.
12. The assembly of claim 11 wherein some of the plurality conduits hingeably connects some of the plurality of reflector panels to the cold plate.
13. The assembly of claim 11 wherein the reflector panels are circumferentially distributed about the cold plate.
14. The assembly of claim 11 wherein a plurality of concentrated photovoltaic cells are mounted on one side of the cold plate, wherein the plurality of conduits are thermally coupled to on the opposite side of the cold plate.
15. A method of moveably securing reflective panel assemblies comprising:
communicating thermal energy to a plurality of reflective panels using a conduit; and
hingeably connecting the plurality of reflective panels directly to each other using the conduit pivoting the panels between a stowed position and a deployed position, wherein each of the panels extends within a plane, and the planes of the panels are aligned in the stowed position and the deployed position; and
providing a secondary reflector, wherein the plurality of reflective panels are aligned with the secondary reflector and spaced therefrom when the plurality of reflective panels are in the deployed position.
16. The method of claim 15 wherein the reflective panels comprise Fresnal reflector on a first surface and the conduit secured to a second surface opposite the first surface.
17. The method of claim 15 including flexing at least a portion of the conduit when hinging.
18. The method of claim 15 including hingeably connecting at least some of the plurality of reflective panels to a cold plate using the conduit.
