Abstract
Abstract The invention relates to a solar pick-up comprising a panel and means associated with this panel, suitable for absorbing the solar radiation and for heating a fluid, wherein said means are constituted by a thin metal foil which covers virtually all the panel and which presents at least one first face exposed directly to the solar radiation, blackened and treated on the surface to pick up the solar radiation and a second face, opposite the first, in direct contact over virtually the whole of its surface with said fluid, said foil transmitting the picked-up heat to said fluid through its thickness.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
113 words
A solar pick-up comprising a body of fluid and a thin sheet, or foil, for conductively transferring solar energy directly to said fluid, said thin metal sheet, or foil, having an arborescent dendritic surface configuration having primary and secondary reliefs on one side, said arborescent dendritic surface being provided with a heat-absorptive coating to be exposed to solar energy, the opposite side of the sheet, or foil, being in direct contact over virtually the whole of its surface with said fluid, said sheet, or foil, being self-supporting, impermeable to said fluid and being substantially entirely formed by electro-deposition of thermally-conductive metal whereby heat absorption is substantially unaffected by the angle of incident light.
Claim 2
Dependent Claim
113 words
A solar pick-up comprising a body of fluid and a thin sheet, or foil, for conductively transferring solar energy directly to said fluid, said thin metal sheet, or foil, having an arborescent dendritic surface configuration having primary and secondary reliefs on one side, said arborescent dendritic surface being provided with a heat-absorptive coating to be exposed to solar energy, the opposite side of the sheet, or foil, being in direct contact over virtually the whole of its surface with said fluid, said sheet, or foil, being self-supporting, impermeable to said fluid and being substantially entirely formed by electro-deposition of thermally-conductive metal whereby heat absorption is substantially unaffected by the angle of incident light.
Claim 3
Dependent Claim
33 words
A solar pick-up as claimed in claim 1, wherein the sheet or foil, due to its indentation, presents a much greater surface of absorption than its projection along its own plane of development.
Claim 4
Dependent Claim
44 words
A solar pick-up as claimed in claim 1, wherein a first face of the foil faces at least one first transparent covering forming a glass house effect and a second face is in contact with a continuous and relatively thin layer of said fluid.
Claim 5
Dependent Claim
46 words
A solar pick-up as claimed in claim 3, wherein said sheet, or foil and at least said first transparent covering form a floating plate in a tank of water and this plate is associated with a plurality of similar, essentially independent plates floating in said tank.
Claim 6
Dependent Claim
17 words
A solar pick-up as claimed in claim 3, wherein said sheet, or foil floats on said fluid.
Claim 7
Dependent Claim
48 words
A solar pick-up as claimed in claim 5, wherein said sheet, or foil is fast with and parallel to at least said first transparent covering forming a glass house effect and floats therewith on said fluid, forming between the foil and said first transparent covering a closed space.
Claim 8
Dependent Claim
40 words
A solar pick-up as defined in claim 1, wherein said first mentioned sheet, or foil, comprises copper, and also includes another metal electrodeposited on said dendritic surface below said heat-absorptive coating, said dendritic surface being retained in the final product.
Claim 9
Dependent Claim
42 words
A solar pick-up as claimed in claim 7, wherein said copper sheet, or foil is applied to a transparent support on the dendritic surface and said copper foil floats with said first transparent covering and with this transparent support on said fluid.
Claim 10
Dependent Claim
16 words
A solar pick-up as defined in claim 1, wherein said metal sheet, or foil, comprises copper.
