Abstract
Abstract A solar collector of generally improved design is provided wherein the collector element comprises a flat absorber plate formed of two sheets of a conductive metal treated in a bonding process under heat and pressure with portions of the sheets spaced in such a way as to provide a sinuous passage from one end of the collector to the other with flat portions of the plate between said passages. The collector has a double glazing over the absorber plate to provide an air space between the sheets of glass and between the glazing and the absorber plate. A feature of the invention is in the fabrication of the collector utilizing novel metal extruded frame members combined with wood frame members. This combination provides an effective means for sealing the elements against the weather and for holding the various elements in correct alignment as well as resisting loads of snow or sleet. The design of the bonded absorber plate insures that every molecule of water is treated in the same way and in a typical embodiment, the temperature is raised from 4° F. to 10° F. in each pass.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
310 words
A solar collecor comprising in combination: a. a generally flat absorber plate, said plate being formed of two bonded sheets of condutive metal with a sinuous fluid passage formed between portions thereof with flat portions between said passages; b. a double glazing of two sheets of glass over said plate to form a dead air space between said sheets and between said sheets and said flat plate, whereby a fluid such as water or air can flow into said passage at one end of said plate, through the entire length of said sinuous passage and out the other end of said plate; c. a frame made by combining metal extruded members with wood members surrounding said plate and extending above said plate, said metal exturded frame is provided with inwardly extending ledges including a first ledge to hold the flat plate, a second ledge to hold the bottom sheet of the glazing, a spacer (63) surrounding said glazing to hold said glazing and permit expansion and contraction and a top ledge spaced from the top of the top sheet, and a spring clip sprung between said top sheet and said ledge to provide a substantially weatherproof connection at the top of the collector, wherein said metal extruded frame having an outer wall and an inner wall, said wall being parallel to each other and spaced apart, said walls being connected together by a sloping top wall, sloping upward from the outer wall to the inner wall, and each wall having inwardly extending projections and a wooden frame member within said walls, said wooden member having a groove therein whereby said inner wall with the projection from the inner wall lying in said groove and said wooden member being held in spaced relationship to the top wall and the outer wall by the respective projections in said top and outside walls.
Claim 2
Dependent Claim
310 words
A solar collecor comprising in combination: a. a generally flat absorber plate, said plate being formed of two bonded sheets of condutive metal with a sinuous fluid passage formed between portions thereof with flat portions between said passages; b. a double glazing of two sheets of glass over said plate to form a dead air space between said sheets and between said sheets and said flat plate, whereby a fluid such as water or air can flow into said passage at one end of said plate, through the entire length of said sinuous passage and out the other end of said plate; c. a frame made by combining metal extruded members with wood members surrounding said plate and extending above said plate, said metal exturded frame is provided with inwardly extending ledges including a first ledge to hold the flat plate, a second ledge to hold the bottom sheet of the glazing, a spacer (63) surrounding said glazing to hold said glazing and permit expansion and contraction and a top ledge spaced from the top of the top sheet, and a spring clip sprung between said top sheet and said ledge to provide a substantially weatherproof connection at the top of the collector, wherein said metal extruded frame having an outer wall and an inner wall, said wall being parallel to each other and spaced apart, said walls being connected together by a sloping top wall, sloping upward from the outer wall to the inner wall, and each wall having inwardly extending projections and a wooden frame member within said walls, said wooden member having a groove therein whereby said inner wall with the projection from the inner wall lying in said groove and said wooden member being held in spaced relationship to the top wall and the outer wall by the respective projections in said top and outside walls.
Claim 3
Dependent Claim
97 words
The solar collector of claim 1 which includes the following additional structure: a. at least some of the projections on the top, inner and outer walls of paragraph c include holes for the reception of self tapping screws, b. the metal extrusions of paragraph a are cut at a 45° angle to form a corner and c. self tapping screws extend through said outer walls at each side of a corner formed by said extrusions, each of said screws extending through an outer wall and into a hole of paragraph a hereof in the mating corner member.
Claim 4
Dependent Claim
76 words
The solar collector of claim 1 wherein the collector is divided in two sections w ith an extruded cross member separating the two sections, said cross member including an upright with a first pair of outwardly directed lips to retain said glazing and a second pair of outwardly extending lips to retain a spring clip sprung against the top of said glazing and a spacer (63) permitting expansion and contraction between said upright and said glazing.
Claim 5
Dependent Claim
70 words
The solar collector of claim 1 including the following additional structure: a. a plurality of wood stringers (40) extending from one side of the collector to the other, said stringers being located under said absorber plate, b. foam rubber insulation (42) between said stringers and c. a thin metal bottom plate (25) extending to the outer walls of paragraph a of claim 8 retaining said stringers and said bottom plate.
Claim 6
Dependent Claim
55 words
The structure of claim 1 wherein the flat absorber plate is made of two bonded copper sheets with a single continuous S-shaped or sinuous passage extending from one end of the collector to the other, whereby all fluid entering one end of the passage passes through the complete passage before discharge at the opposite end.
Claim 7
Dependent Claim
42 words
The solar collector of claim 1 wherein the two sheets of glass have a spacer extending at the edges thereof, said spacer being hollow and having openings extending into the space between the glasses, said hollow spacer having a dehydrating agent therein.
Claim 8
Dependent Claim
31 words
The structure of claim 1 wherein said metal extruded frame includes a plurality of screw holes whereby self-tapping screws can be passed through mating frame elements to hold the frame together.
