  • Patent number: 4770162
    Abstract: In accordance with the present invention, an improved receiving surface, preferably a reflector surface and preferably of the parabolic trough type, for a radiant solar energy collector system comprises an essentially open frame means defining the perimeter of an extended receiving surface and a plurality of elongated, flexible strips mounted on said frame means in parallel relation to one another, each of the strips having a width substantially less than one dimension of the frame means, whereby a plurality of the strips cover essentially the entire open area of the frame to form an essentially continuous receiving surface.

  • Patent number: 4604990
    Abstract: In accordance with the present invention, an improved collector means for a solar energy collector system having an absorber plate and a glazing panel spaced from at least one side of the absorber plate in which a cap means is coupled to and extends along one edge of the absorber plate and a depending leg extends over the complimentary edge of the glazing panel, the cap means having formed therein at least one air channel conforming in shape to the cross-sectional shape of the cap means and having air inlet means adjacent the bottom of a leg of the cap means in communication with the channel and an air outlet means adjacent the top of the cap means and in communication with the channel and adapted to permit currents of cooling air to pass therethrough from the inlet to the outlet, thereby maintaining said complimentary edge of the glazing panel relatively cool.

  • Patent number: 4263893
    Abstract: Solar energy collector construction wherein the collector is composed of a skeleton framework, preferably of I-beam configuration interconnected so that it may be folded into a compact configuration for storage and shipment and which may be erected and locked into expanded configuration at the erection site so as to provide a sturdy structure which is highly resistant to wind loading and yet is fully effective in operation and use. Another feature is the design and mounting of the reflective elements which permits the reflective elements to be replaced periodically as they become less efficient reflectors through exposure to the elements. An improved collector construction is disclosed wherein the absorber element is in the form of a plate having passages therein for the flow of heat exchange fluid therethrough, the absorber plate being mounted within an enclosed light- and radiant-energy-transparent envelope which minimizes loss of heat from the absorber element by convection and conduction.

  • Patent number: 4024852
    Abstract: A system including a non-tracking reflector-collector for the concentration and collection of solar energy. An energy-collecting plate is disposed upright along a substantially horizontal axis substantially coincident with the east-west direction of the earth. The collector plate is positioned within a semi-tubular reflector having parabolic sidewalls. The reflector surfaces on opposite sides of the collector plate are parabolic surfaces, each having a focal point approximately coincident with the upper terminal edge of the collector plate. The axes of the parabolas which define the respective surfaces are rotated about or diverge from their common focal point at a substantial angle. The reflector sides are of laminated construction having a base portion of a lightweight rigid plastic sheet, an underlayer of plastic corrugated board and a reflective film on the interior surface. The collector plate receives energy entering the aperture between the reflective surfaces.
