Abstract
Abstract The invention relates to a sensor equipped with a member which selectively absorbs solar energy. This member is constituted by two sheets of a rigid material serving as a support for a layer of material which is sensitive to solar radiation, the two sheets being joined together over their entire length and folded in such a way that the member has a lozenge-shaped cross-section, which can be applied in four contact zones against a tubular wall and can remain in intimate and permanent contact with the latter, no matter what the temperature variations undergone by the assembly.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
105 words
A solar sensor comprising an outer tubular transparent glass envelope and an inner tubular glass envelope defining between them an enclosure which is placed under vacuum, the inner envelope serving as a wall of a recess which itself receives a heat exchanger, and a solar energy absorbing member introduced between the outer and inner envelopes, said absorbing member comprising two sheets made from a metal, each of which is folded in accordance with an angle α, such that after assembly of said two sheets the absorbing member has a lozenge-shaped cross-section surrounding the inner envelope and resiliently engaging with the latter in four contact zones.
Claim 2
Dependent Claim
105 words
A solar sensor comprising an outer tubular transparent glass envelope and an inner tubular glass envelope defining between them an enclosure which is placed under vacuum, the inner envelope serving as a wall of a recess which itself receives a heat exchanger, and a solar energy absorbing member introduced between the outer and inner envelopes, said absorbing member comprising two sheets made from a metal, each of which is folded in accordance with an angle α, such that after assembly of said two sheets the absorbing member has a lozenge-shaped cross-section surrounding the inner envelope and resiliently engaging with the latter in four contact zones.
Claim 3
Dependent Claim
17 words
A solar sensor according to claim 1, wherein the first and second sheets are made from steel.
Claim 4
Dependent Claim
26 words
A solar sensor according to claim 2, wherein the first sheet is coated with a thin layer of a material which is sensitive to solar radiation.
Claim 5
Dependent Claim
14 words
A solar sensor according to claim 3, wherein said sensitive material is plated copper.
Claim 6
Dependent Claim
15 words
A solar sensor according to claim 3, wherein said sensitive material is electrolytically deposited copper.
Claim 7
Dependent Claim
28 words
A solar sensor according to claim 2, wherein the first and second sheets are coated with a thin layer of a material which is sensitive to solar radiation.
Claim 8
Dependent Claim
14 words
A solar sensor according to claim 6, wherein said sensitive material is plated copper.
Claim 9
Dependent Claim
15 words
A solar sensor according to claim 6, wherein said sensitive material is electrolytically deposited copper.
Claim 10
Dependent Claim
29 words
A solar sensor according to claim 2, wherein one of said sheets that is not exposed to solar radiation on its outer face is polished on its outer face.
Claim 11
Dependent Claim
120 words
A solar panel comprising a plurality of solar sensors arranged overhead, each of said solar sensors comprising an outer tubular transparent glass envelope and an inner tubular glass envelope defining between them an enclosure which is placed under vacuum, the inner envelope serving as a wall of a recess which itself receives a heat exchanger, and a solar energy absorbing member introduced between the outer and inner envelopes, said member comprising two sheets made from a good heat conducting material, each of which is folded in accordance with an angle α, such that after assembly of said two sheets the absorbing member has a lozenge-shaped cross-section surrounding the inner envelope and resiliently engaging with the latter in four contact zones.
