Claim 1
Independent Claim
327 words
A wall or roof panel for use in a building as a solar collector or in a solar collector system, comprising a folded plate-type structural member composed of at least one collector first plate element and at least one connecting second plate element alternatively arranged in substantially zig-zag manner with each collector first plate connected at one edge to the adjoining connecting second plate or at opposite edges to alternate second plates when present, the connecting second plates when more than one is present extending in substantially parallel planes and the collector first plates when more than one is present extending in substantially parallel planes oriented at substantially the same tilt angle with respect to the planes of the second plates whereby all of the collector first plates present can be positioned transverse to incident solar energy when the wall or roof panel is mounted in operating position for optimizing the collector plate angle with relation to incident solar energy, the edge connections between collector first plate elements and connecting second plate elements forming the folds and providing structural strength of the panel in the direction parallel to the length of the folds, said panel having at least one wall portion transparent to solar energy, each of the collector first plates being insulated from the outside ambiance by said transparent wall portions and being energy absorbent, said collector first plates being in heat-exchange relationship with a fluid-conveying structure in the panel whereby solar energy when incident on said transparent wall portions will be transmitted therethrough to be absorbed by the absorbent collector first plate elements and absorbed heat transferred to fluid passed through the fluid-conveying structure, said folded plate structural member and said edge connections between connecting first and second plate elements forming a stiffened integral structure which is substantially self-supporting and capable of functioning as a load-bearing solar-energy-receiving structural element when installed in said operating position as an integral wall or roof panel of a building.
Claim 2
Dependent Claim
327 words
A wall or roof panel for use in a building as a solar collector or in a solar collector system, comprising a folded plate-type structural member composed of at least one collector first plate element and at least one connecting second plate element alternatively arranged in substantially zig-zag manner with each collector first plate connected at one edge to the adjoining connecting second plate or at opposite edges to alternate second plates when present, the connecting second plates when more than one is present extending in substantially parallel planes and the collector first plates when more than one is present extending in substantially parallel planes oriented at substantially the same tilt angle with respect to the planes of the second plates whereby all of the collector first plates present can be positioned transverse to incident solar energy when the wall or roof panel is mounted in operating position for optimizing the collector plate angle with relation to incident solar energy, the edge connections between collector first plate elements and connecting second plate elements forming the folds and providing structural strength of the panel in the direction parallel to the length of the folds, said panel having at least one wall portion transparent to solar energy, each of the collector first plates being insulated from the outside ambiance by said transparent wall portions and being energy absorbent, said collector first plates being in heat-exchange relationship with a fluid-conveying structure in the panel whereby solar energy when incident on said transparent wall portions will be transmitted therethrough to be absorbed by the absorbent collector first plate elements and absorbed heat transferred to fluid passed through the fluid-conveying structure, said folded plate structural member and said edge connections between connecting first and second plate elements forming a stiffened integral structure which is substantially self-supporting and capable of functioning as a load-bearing solar-energy-receiving structural element when installed in said operating position as an integral wall or roof panel of a building.
Claim 3
Dependent Claim
39 words
A wall or roof panel as claimed in claim 1, wherein each collector first plate comprises a metal member whose surface facing the transparent wall portion is spaced from the latter and is treated to enhance solar energy absorption.
Claim 4
Dependent Claim
24 words
A wall or roof panel as claimed in claim 2, wherein the outer surfaces of the connecting second plates are reflective for solar energy.
Claim 5
Dependent Claim
24 words
A wall or roof panel as claimed in claim 1, wherein the panel comprises an insulating support member integrally connected to the folded-plate member.
Claim 6
Dependent Claim
247 words
A wall or roof panel for use in a building in a solar collector system, comprising an elongated folded plate structural member composed of at least one collector first plate element and at least one adjoining connecting second plate element alternately arranged in a substantially zig-zag manner, structural means connecting together the adjacent edges of each collector first plate with the adjoining connecting second plate, the plane of the collector first plate extending at a predetermined tilt angle with respect to the plane of the second plate whereby the collector first plate can be located transverse to impinging solar energy when the panel is mounted in operative position, said collector first plate having an areal portion absorbent of solar energy and a wall transparent to solar energy mounted in front of the absorbent portion, means for heat insulating the absorbent portion from ambient temperature, and means providing fluid flow across the collector first plate and in heat-exchange relationship with the absorbent portion, whereby solar energy when impinging on said transparent wall will be transmitted therethrough to be absorbed by the absorbent portion which in turn transfers heat to the fluid passing across the collector first plate, said folded plate structural member and said edge connections between connecting first and second plate elements forming a stiffened integral structure which is substantially self-supporting and capable of functioning as a load-bearing solar-energy-receiving structural element when installed in said operative position as an integral wall or roof panel of a building.
