Abstract
Abstract A method is provided for fabricating a solar panel of different interior and exterior materials to utilize the structural and heat absorbing properties of the exterior material and the corrosion resistance of the interior material. The materials are intimately wedded along the entire length of the same by applying a fluid pressure internally against the interior material and simultaneously throughout the entire lengths of the same to displace the interior material into intimate contact with the exterior material. The fluid pressure is applied with a force which permanently deforms the interior material but which is within the elastic limit of the exterior material so that when the pressure is relieved, the exterior material contracts against the interior material causing it to deform inwardly due to compression. The resultant dimensional excursions of the interior material results in the work hardening of same. The exterior material is formed by extrusion to have diametrally extending fins, one of which terminates in a socket so that a plurality of such panels can be readily assembled in edge-to-edge relation. The apparatus employed incorporates hollow mandrels for internally engaging the lining and supporting the same while permitting a fluid pressure to be internally applied thereto and while, at the same time, permitting a relief of the pressure so that the elastic limit of the exterior material is not exceeded. The apparatus furthermore includes a device for applying the pressure impulse or impact force to the lining for deforming the lining against the exterior part.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
132 words
A method comprising fabricating a solar panel of different interior and exterior materials to utilize the structural and heat absorbing properties of the exterior material and the corrosion resistance of the interior material, said fabricating being effected by intimately wedding the materials along the entire length of the same by applying a fluid pressure internally against the interior material and simultaneously throughout at least substantially the entire length of the same to displace the interior material into intimate contact with the exterior material, the fluid pressure being applied with a force which permanently deforms the interior material and elastically deforms the exterior material within the elastic limit of the exterior material, and thereafter relieving said pressure so that the exterior material contracts against the interior material to work harden the interior material.
Claim 2
Independent Claim
132 words
A method comprising fabricating a solar panel of different interior and exterior materials to utilize the structural and heat absorbing properties of the exterior material and the corrosion resistance of the interior material, said fabricating being effected by intimately wedding the materials along the entire length of the same by applying a fluid pressure internally against the interior material and simultaneously throughout at least substantially the entire length of the same to displace the interior material into intimate contact with the exterior material, the fluid pressure being applied with a force which permanently deforms the interior material and elastically deforms the exterior material within the elastic limit of the exterior material, and thereafter relieving said pressure so that the exterior material contracts against the interior material to work harden the interior material.
Claim 3
Dependent Claim
21 words
A method as claimed in claim 1 wherein the exterior material is aluminum and the interior material is copper or brass.
Claim 4
Dependent Claim
56 words
A method as claimed in claim 1 wherein the interior material is supplied in tubular form and the exterior material is extruded to at least partly tubular form having an inside bore large enough to accommodate the tubular interior material, the interior material being inserted into the exterior material prior to the application of said pressure.
Claim 5
Dependent Claim
56 words
A method as claimed in claim 2 wherein the interior material is supplied in tubular form and the exterior material is extruded to at least partly tubular form having an inside bore large enough to accommodate the tubular interior material, the interior material being inserted into the exterior material prior to the application of said pressure.
Claim 6
Dependent Claim
27 words
A method as claimed in claim 4 wherein the spacing between the material is .003 to .020 inches on a diametral basis before said pressure is applied.
Claim 7
Dependent Claim
23 words
A method as claimed in claim 1 wherein the interior material is softened and the exterior material is hardened prior to being wedded.
Claim 8
Dependent Claim
23 words
A method as claimed in claim 4 wherein the interior material is softened and the exterior material is hardened prior to being wedded.
Claim 9
Dependent Claim
41 words
A method as claimed in claim 7 wherein the exterior material is extruded to have diametrically extending fins with one of said fins terminating in a socket so that a plurality of said panels can be readily assembled in edge-to-edge relation.
Claim 10
Dependent Claim
39 words
A method as claimed in claim 6 wherein said pressure is applied as an impact force to deform the interior material against the exterior material which thereafter compresses against the interior material whereby the interior material is work hardened.
Claim 11
Dependent Claim
12 words
A method as claimed in claim 1 comprising blackening the exterior material.
Claim 12
Dependent Claim
12 words
A method as claimed in claim 8 comprising blackening the exterior material.
Claim 13
Dependent Claim
43 words
A method as claimed in claim 3 comprising forming the panel in elongate form to have a length which exceeds the outer diameter of the tubular portion of the exterior material by an order of magnitude of at least about one hundred times.
Claim 14
Dependent Claim
36 words
A method as claimed in claim 3 wherein interior material is longer than the exterior material to provide an excess at opposite ends of the exterior material which is engaged for the application of said pressure.
Claim 15
Dependent Claim
39 words
A method as claimed in claim 3 wherein the exterior material is extruded to have diametrically extending fins with one of said fins terminating in a socket, and assembling a plurality of said panels in edge-to-edge and fin-to-socket relation.
Claim 16
Dependent Claim
33 words
A method as claimed in claim 2 wherein the aluminum is preliminarily treated to have a tensile strength in the order of magnitude of 32,000 psi and the interior material is soft annealed.
Claim 17
Dependent Claim
28 words
A method as claimed in claim 1 wherein the force applied by the fluid pressure produces stress in the outer material in the vicinity of the elastic limit.
