Abstract
The solar collector comprises a plurality of direction adjustable elongated parabolic reflectors arranged side by side. Along the focus of the reflectors are tubes for a heat collecting medium. The tubes are to be connected to heat exchangers or the like. Each reflector consists of reflector wall portions movably connected to each other and operable from an open parabolic reflector position to a non-reflector position entirely enclosing the tubes, and forming a relatively flat structure resembling a venetian blind slat.
Claims13
A solar collector combined within a window and including a plurality of elongated thinwalled reflectors arranged side by side and adjustable in direction and each designed to reflect incident radiation towards an associated longitudinal focus along which conveying means for a liquid heat transferring medium extends,
- said conveying means being arranged to be connected to a heat collecting device,
- the walls of each of the reflectors being foldable to surround the associated conveying means,
- said conveying means for said respective reflectors comprising tubes arranged mutually parallel and extending between opposite sides of the window and being connected in series with a common outlet and a common inlet,
- said common outlet and common inlet being positioned at a central pivot axis of the window for connection by means of rotatable couplings to connecting tubes for similar adjacent window frames.
A solar collector including a plurality of elongated thin-walled reflectors arranged side by side and adjustable in direction and each designed to reflect incident radiation towards an associated longitudinal focus along which conveying means for a liquid heat transferring medium extends,
- said conveying means being arranged to be connected to a heat collecting device,
- the walls of each of the reflectors being foldable to surround the associated conveying means,
- the walls of each reflector consisting of two wall portions which are pivotally interconnected along an elongated pivot means for movement between an unfolded reflector condition and a folded condition,
- said wall portions defining an essentially winglike shape within which said conveying means are enclosed when said wall portions are in the folded condition,
- said solar collector comprising a venetian blind structure wherein the foldable walls of said reflectors form the venetian blind slats and in which the folded condition of said reflectors provides the light transmitting condition of the venetian blind,
- the unfolded position of the reflector walls providing the light obstructing condition of the venetian blind.
