Abstract
Solar collector without outer glass isolation in the shape of a usual roof cover, especially a roof cover having undulations, comprising integral passageways on the lower side of the roof cover and spaced apart from each other, and crossing channels which can be connected to the passageways, especially by pressing connecting openings one upon the other.
Claims12
A solar collector comprising a sinuous roofing sheet, said sheet having a fluid passage means for carrying a fluid heat-carrier, wherein said fluid passage means comprises a plurality of longitudinally extending tubular channels integrally formed on the lower surface of said roofing sheet, beneath each trough of said sheet each channel being spaced apart from its adjacent channels by a distance substantially greater than the channel width, a cross pipe extending laterally across said channels adjacent each end of the roofing sheet, means for attaching said roofing sheet to said cross pipes, means for fluidly connecting said cross pipes to said tubular channels whereby one cross pipe forms an inlet for the fluid heat carrier, and
- wherein the tubular channels and the cross pipes each include at least one flat wall portion at their connection which abut against each other, each flat wall portion including a connecting bore and further comprising sealing means disposed around registering connecting bores when said flat wall portions abut each other.
For use with a building having a roof, a solar collector comprising:
- a roofing sheet comprising a plurality of elongated strip members, each strip member being in the shape of a single wave in cross section, each strip member beginning and terminating at a point intermediate the crest and trough of the wave shape,
- means formed along the longitudinal edges of each strip member for locking adjacent strip members together,
- said locking means comprising a hook member integrally formed along one edge of each strip member and a receiving groove for said hook integrally formed along the opposite edge of each strip member,
- fluid passage means formed longitudinally along the trough portion of each strip member for carrying a fluid heat carrier,
- a cross pipe secured laterally across said roofing sheet adjacent each end, and
- means for fluidly connecting said fluid passage means to said cross pipes whereby one cross pipe forms an inlet while the other cross pipe forms an outlet.
