Abstract
Abstract A heat exchange panel possessing a system of internal fluid passageways defining at least two longitdudinally extended headers extending substantially the length of the panel, a connecting header located at one end of the panel in a direction transverse to the longitudinally extended headers and interconnecting same, a plurality of connecting portions of said passageways extending transversely between the respective longitudinally extended headers, and fluid exit and entry portions extending longitudinally from at least two of said headers. The configuration of the headers serves to reduce pressure drop while maintaining uniformity of fluid flow under high velocity, and renders the panel eminently suitable for solar energy applications.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
108 words
A heat exchange panel possessing a system of internal tubular passageways, said tubular passageways defining at least three generally tapered longitudinally extended headers, at least two of said longitudinally extended headers extending substantially the length of said panel, a connecting header located at one end of said panel transverse to and interconnecting longitudinally extended headers, and generally transversely extended connecting portions of said passageways, said connecting portions extending between longitudinally extended headers, and at least two fluid entry and exit portions longitudinally extending from at least two of said headers, wherein said longitudinally extended headers include a centrally located header offset by a pair of laterally displaced headers.
Claim 2
Dependent Claim
108 words
A heat exchange panel possessing a system of internal tubular passageways, said tubular passageways defining at least three generally tapered longitudinally extended headers, at least two of said longitudinally extended headers extending substantially the length of said panel, a connecting header located at one end of said panel transverse to and interconnecting longitudinally extended headers, and generally transversely extended connecting portions of said passageways, said connecting portions extending between longitudinally extended headers, and at least two fluid entry and exit portions longitudinally extending from at least two of said headers, wherein said longitudinally extended headers include a centrally located header offset by a pair of laterally displaced headers.
Claim 3
Dependent Claim
14 words
The panel of claim 1 wherein said connecting header is essentially rectangular in shape.
Claim 4
Dependent Claim
107 words
The panel of claim 1 wherein said longitudinally extended headers are generally tapered and comprise a single, centrally located inlet header flanked by a pair of laterally displaced, opposed outlet headers, said inlet header and said outlet headers possess their respective areas of greatest width at opposite ends of said panel, a single entry portion extending longitudinally away from said inlet header from the area of greatest width thereof, a generally rectangularly shaped connecting header located at the end of said panel furthest from said entry portion, and a single exit portion extending longitudinally away from said connecting header in the opposite direction to said entry portion.
Claim 5
Dependent Claim
104 words
The panel of claim 1 wherein said longitudinally extended headers are generally tapered and comprise a pair of laterally displaced, opposed inlet headers flanking a single, centrally located outlet header, said inlet headers and said outlet header possess their respective areas of greatest width at opposite ends of said panel, a pair of laterally opposed entry portions extending longitudinally away from said inlet headers from the areas of greatest width thereof, a generally rectangularly shaped connecting header located adjacent and between said entry portions, and a single exit portion extending longitudinally away from said outlet header in the opposite direction to said entry portions.
Claim 6
Dependent Claim
50 words
The panel of claim 1 wherein said longitudinally extended headers comprise a pair of opposed, laterally displaced lateral header structures, and a pair of longitudinally opposed, central header structures located therebetween, and entry and exit portions extending, respectively, from said central header portions in opposite directions away from each other.
Claim 7
Dependent Claim
45 words
The panel of claim 1 wherein the areas of greatest width of said headers are offset from each other so that the areas of greatest width of each of said headers are adjacent to the areas of least width of the other of said headers.
Claim 8
Dependent Claim
16 words
The panel of claim 1 wherein said panel is utilized in a solar energy collector system.
Claim 9
Dependent Claim
36 words
The panel of claim 1 wherein said longitudinally extended headers are provided with a plurality of bonded portions which provide interruption in the flow of said heat exchange medium and increase resistance to rupture under pressure.
Claim 10
Dependent Claim
13 words
The panel of claim 8 wherein said bonded portions comprise essentially circular islands.
Claim 11
Dependent Claim
18 words
The panel of claim 1 wherein said connecting portions comprise a plurality of spaced parallel individual tubular passageways.
Claim 12
Dependent Claim
38 words
The panel of claim 10 wherein said connecting portions are inclined with respect to the direction of fluid flow and are displaced at an angle of at least 91° with respect to the longitudinal dimension of said panel.
Claim 13
Dependent Claim
23 words
The panel of claim 11 wherein said connecting portions define an angle of from 92° to 100° with respect to said longitudinal dimension.
Claim 14
Dependent Claim
42 words
The panel of claim 1 wherein one of said headers is an inlet header and one of said headers is an outlet header, provided that said entry portion extends from said inlet header and said exit portion extends from said outlet header.
Claim 15
Dependent Claim
20 words
The panel of claim 13 wherein the area of greatest width of said inlet header is adjacent said entry portion.
Claim 16
Dependent Claim
20 words
The panel of claim 14 wherein the area of greatest width of said outlet header is adjacent said exit portion.
Claim 17
Dependent Claim
11 words
The panel of claim 1 including three of said tapered headers.
Claim 18
Dependent Claim
24 words
The panel of claim 16 wherein one of said headers is an inlet header and the other two of said headers are outlet headers.
Claim 19
Dependent Claim
23 words
The panel of claim 16 wherein two of said headers are inlet headers and the other of said headers is an outlet header.
