Abstract
Abstract A device for collecting solar energy, for incorporation in a dwelling, especially in a tiled roof, comprises a heat-absorbing plate, ducting for a heat-exchange fluid for extracting heat from the plate, and single or double glazing over the plate, this glazing consisting of a plurality of radiation - transmitting tiles each having a recessed rear face defining a cell, whereby convection between the glazing and the absorbing surface is reduced or eliminated.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
138 words
A solar-energy collector adapted to be mounted in and to form part of a building structure, comprising: a solar-energy absorbing plate; conduit means running along said plate for passing a heat-carrying fluid in heat-exchanging relationship with said plate, said plate having a face turned toward the sun; an array of formations projecting outwardly from said face of said plate turned toward the sun; a multiplicity of flat hollow elements; and means on each said element to hook onto said formations so that said elements cover said plate on the side thereof turned toward the sun while lying in side-by-side relation to one another, said elements having surfaces defining with said plate respective cells limiting the circulation of air in the region of said plate and confining heat by the greenhouse effect, said elements being transparent to solar radiation.
Claim 2
Dependent Claim
138 words

Claim 3
Dependent Claim
19 words
The solar energy collector defined in claim 1 wherein said elements are disposed in successive rows on said plate.
Claim 4
Dependent Claim
47 words
The solar collector defined in claim 2 wherein the elements of each of said rows overlap the elements of an adjacent row and said elements are imbricated such that radiation onto said plate and radiation from said plate passes through two superposed cells formed by overlapping elements.
Claim 5
Dependent Claim
19 words
The solar energy collector defined in claim 3 wherein said elements are disposed in contiguous relation with no overlapping.
Claim 6
Dependent Claim
79 words
The solar energy collector defined in claim 4 wherein each of said elements is formed with a rear portion of a material permeable to said radiation and extending beneath an element of an adjacent row so that each rear portion defines a first cell with said plate and the overlying element of the adjacent row defines a second cell such that radiation passing to or from said plate traverses both a first and a second cell at any location.
Claim 7
Dependent Claim
32 words
The solar energy collector defined in claim 1 wherein said formations are constituted by respective passes of a pipe fixed to an upper surface of said plate and forming said conduit means.
Claim 8
Dependent Claim
32 words
The solar energy collector defined in claim 1, further comprising a casing connected to said plate and enclosing the surface thereof turned away from the sun, and means for insulating said casing.
Claim 9
Dependent Claim
29 words
The solar energy collector defined in claim 7, wherein said casing has a lateral wall formed with shutter means actuatable to permit the flow of air through said casing.
Claim 10
Dependent Claim
25 words
The solar energy collector defined in claim 1, wherein said elements are formed with joints enabling the sealing of the respective cells from one another.
Claim 11
Dependent Claim
27 words
The solar energy collector defined in claim 1 wherein said elements are provided with lateral walls formed with openings enabling the draining of water from said cells.
Claim 12
Dependent Claim
35 words
The solar energy collector defined in claim 1 wherein at least part of each of said elements is colored to conform to the coloration of a portion of said structure adjoining the solar energy collector.
