Solar heat transfer apparatus
View Patent ↗Heat transfer apparatus comprising, in combination inner and outer bodies defining a space therebetween which extends at least part way about an axis, at least one of the bodies being heat conductive, a heat conductive woven mesh extending in the space at least part way about the axis, and in heat transfer relation with at least one of the bodies, fluid in the space in heat transfer contact with the mesh, and solar cells carried by the outer body.
1. Heat transfer apparatus comprising, in combination:
a) inner and outer bodies defining an axially extending annular space therebetween which extends at least part way about said axis, at least one of the bodies being heat conductive,
b) a heat conductive woven mesh extending axially and annularly in said space at least part way about said axis, and in heat transfer relation with at least one of the bodies, the mesh also extending crosswise of said space to contact annular surfaces defined by said inner and outer bodies, along axial length of said mesh, said surfaces at locations facing and contacting the mesh along their lengths being free of indentations, the mesh confined between said annular surfaces and being separate from said bodies,
c) and fluid in said space flowing axially and through the mesh between spaced apart mesh wires in heat transfer contact with said mesh, along the mesh length that extends about said axis,
d) and solar cells carried by the outer body in heat transfer relation therewith,
e) there also being heat dissipating means on the outer body and to which said heat is transferred for dissipation, and wherein said means includes fins on said outer body dissipating heat to gas adjacent or near the fins, said solar cells and fins axially spaced apart from one another on the outer body.
2. The combination of claim 1 including an electrical device producing heat which is transferred via said mesh for dissipation.
3. The combination of claim 1 wherein said fluid is liquid.
4. The combination of claim 1 wherein said bodies are generally tubular and coaxial, to define said axis.
5. The combination of claim 1 including a metallic circuit support on the outer body, for carrying at least one of the following
i) power conversion circuitry
ii) control circuitry.
6. The combination of claim 1 wherein the inner body is tubular and defines a bore, and including mass damping means located in said bore.
7. The combination of claim 6 wherein said mass damping means includes cylindrical segments located at selected positions axially, in the bore.
8. The combination of claim 1 including at least one photovoltaic cell carried by the outer body at the exterior thereof.
9. The combination of claim 1 including means for dissipating heat flowing from the mesh to the inner body.
10. The combination of claim 9 wherein said means include a second fluid flowing within the inner body and receiving heat transferred from the mesh to the inner body and then to the second fluid.
