Abstract
Abstract An air solar heating collector assembly is provided having a framework covered by a back plate and a transparent front cover with a thin metal absorber plate mounted centrally therebetween. Baffle members are mounted on both surfaces of the absorber plate and are arranged for alternately splitting and recombining the air flow along both surfaces of the absorber plate. The back plate has air inlet means at one end of the assembly and air outlet means at the other end of the assembly arranged so that the air is admitted simultaneously to and discharged simultaneously from the passages at both sides of the absorber plate. The baffle arrangement is complementary on opposite sides of the absorber plate so that in each region where splitting of the air flow occurs at one side of the plate, recombining of air flow occurs in the corresponding region at the opposite side of the plate.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
220 words
An air solar heating collector assembly, comprising a rectangular framework having oppositely spaced end portions and oppositely spaced side portions, a support plate fastened to and covering the back of said framework, transparent cover means removably supported on and covering the front of said framework, a solar energy absorber plate supported within said framework in parallel spaced relation between said support plate and said cover means, thereby defining a first air passage between said cover means and one surface of said absorber plate and a second parallel air passage between said support plate and the opposite surface of said absorber plate, air inlet means adjacent one end portion of said framework for admitting cool air through said support plate to flow simultaneously across the opposite surfaces of said absorber plate through said first and second air passages, air outlet means adjacent the opposite end portion of said framework for discharging heatred air simultaneously from said passages through said support plate, and baffle means comprising a plurality of baffle members secured in spaced parallel relation to the opposite surfaces of said absorber plate in said first and second air passages, sand baffle members being arranged so that the air flow through each of said passages is alternatively split and recombined during its travel from said inlet means to said outlet means.
Claim 2
Dependent Claim
220 words
An air solar heating collector assembly, comprising a rectangular framework having oppositely spaced end portions and oppositely spaced side portions, a support plate fastened to and covering the back of said framework, transparent cover means removably supported on and covering the front of said framework, a solar energy absorber plate supported within said framework in parallel spaced relation between said support plate and said cover means, thereby defining a first air passage between said cover means and one surface of said absorber plate and a second parallel air passage between said support plate and the opposite surface of said absorber plate, air inlet means adjacent one end portion of said framework for admitting cool air through said support plate to flow simultaneously across the opposite surfaces of said absorber plate through said first and second air passages, air outlet means adjacent the opposite end portion of said framework for discharging heatred air simultaneously from said passages through said support plate, and baffle means comprising a plurality of baffle members secured in spaced parallel relation to the opposite surfaces of said absorber plate in said first and second air passages, sand baffle members being arranged so that the air flow through each of said passages is alternatively split and recombined during its travel from said inlet means to said outlet means.
Claim 3
Dependent Claim
154 words
The assembly of claim 1 further characterized in that said baffle means comprises a first set of baffle members secured in spaced parallel relation to said one surface of said absorber plate in said first air passage for alternately splitting and recombining the air flow through said first air passage, and a second set of baffle members secured in spaced parallel relation to said opposite surface of said absorber plate in said second air passage for alternately splitting and recombining the air flow through said second air passage, said first and second sets of baffle members being arranged in complementary relation so that for each location in said first air passage where splitting of the air flow is effected at said one surface of said absorber plate, recombining of the air flow is effected in the parallel location in said second air passage at said opposite surface of said absorber plate, and vice versa.
Claim 4
Dependent Claim
116 words
The assembly of claim 2 further characterized in that certain of said baffle members in each set are disposed centrally of said absorber plate with their ends spaced from said side portions of said framework for spliting the air flow as it passes through the pair of openings defined between the ends of the centrally disposed baffle members and said side portions, and others of said baffle members in each set are disposed in longitudinally aligned pairs extending inwardly from said side portions of said framework and terminating in spaced relation for recombining the split air stream at it passes through the single central opening defined between the spaced inner ends of said other baffle members.
Claim 5
Dependent Claim
73 words
The assembly of claim 3 further characterized in that each of said centrally disposed baffle members at one surface of said absorber plate has its opposite end portions longitudinally overlapping the inner end portions of an aligned pair of spaced baffle members at the opposite surface of said absorber plate so as to provide structural continuity of the baffle members between said side portions of said framework and thereby stiffening said absorber plate.
Claim 6
Dependent Claim
52 words
The assembly of claim 2 further characterized in that each of said baffle members is an elongated angle member having one leg portion secured to a surface of said absorber plate and the other leg portion extending into one of said air passages substantially perpendicularly to the plane of said absorber plate.
Claim 7
Dependent Claim
65 words
The assembly of claim 5 further characterized in that said other leg portion of each of said baffle members has its outer longitudinal edge spaced slightly from the opposing surface of said cover means or said support plate, whereby to permit limited bypass flow of air over said outer longitudinal edge and thereby preventing stagnation of air at the downstream side of the baffle member.
Claim 8
Dependent Claim
107 words
The assembly of claim 1 further characterized in that said framework includes a pair of spaced flange portions extending laterally inwardly from said side portions and said end portions, said transparent cover means being supported on one of said flange portions in recessed relation within said framework, and retaining means secured to said side portions of said framework in spaced relation below the other of said flange portions, said absorber plate being loosely received in the spaces between said retaining means and said other flange portion and being spaced slightly from said side portions of said framework, whereby to accommodate expansion and contraction of said absorber plate.
Claim 9
Dependent Claim
104 words
The assembly of claim 1 further characterized in that said absorber plate has opposite ends spaced from said end portions of said framework, said air inlet means comprises inlet aperture means in said support plate adjacent one end portion of said framework and aligned with one end of said absorber plate to admit cool air simultaneously into both of said air passages, and said air outlet means comprises outlet aperture means in said support plate adjacent the opposite end portion of said framework and aligned with the opposite end of said absorber plate to discharge heated air simultaneously from both of said air passages.
Claim 10
Dependent Claim
67 words
The assembly of claim 8 further characterized in that said inlet and outlet aperture means comprise elongated slots extending partially across said support plate, and said absorber plate has marginal end portions extending perpendicularly from the plane of the absorber plate into engagement with said support plate across said slots for dividing the inlet and outlet air flow substantially equally between said first and second air passages.
