摘要:
To conduct generating electricity and heating by utilizing solar rays, the solar rays are separated to short wavelength and long wavelength which are separately converged to increase the efficiency of generating and heating. To separate the sunlight, it is preferable to use a semi-transparent mirror for reflecting the short wavelength and for passing the long wavelength. Further, it is preferable that the semi-transparent mirror may act as an optical system for converging the short wavelength.

The energy collector has a housing with a cover which is transparent to vble and thermal radiation. One or more heat collectors are disposed in the interior of the housing. The heat collectors are carried by a pipe through which a heat-transport medium flows. Each of the collectors is assigned a reflector of concave design underneath the respective heat collector. The width of the reflector is significantly greater (e.g. a multiple) than the width of the heat collector. The incident visible and/or thermal radiation is either incident on the front side of the heat collector or it is reflected onto its rear side by the associated reflector. A large portion or all of the rear surface of the collector is covered with photovoltaic elements onto which focused light energy is aimed by the concave reflectors.

A trough-shaped collector for solar radiation for steam generation. A trough-shaped mirror extending in a longitudinal direction receives and reflects radiation onto an absorber line enclosing within its interior a steam generator tube in which water is heated, vaporized and superheated. Heat is transferred transversely from the absorber line to the steam generator tube by heat pipe segments spaced longitudinally along the absorber line.

There is provided an electricity generating system comprising two fluid circuits. The two circuits are in heat exchange relationship, one with the other. The first fluid circuit is in fluid flow connection with the solar heat collecting apparatus rotatable about both the horizontal and vertical axes, and capable of being driven by drive means for rotating the panel about the two axes. The second fluid circuit is in heat exchange relationship with the first fluid circuit such that the fluid in the second circuit is heated to its boiling point by the fluid in the first circuit. Electric generating means are in fluid flow connection within the second circuit to convert heat energy into electricity.

A solar collector of the non-tracking fluid circulating type which is formed of light weight materials and comprises a frame supporting fluid circulating tubes having a light absorber disposed axially therein and lined with retroreflective cube-corners. The tubes are placed in semicircular reflectors and enclosed by a transparent barrier sheet and cover having light anti-reflective coatings.
摘要:
A parabolic-trough solar collector system is disclosed, with each collector driven to track the sun using a ring driven in centerless fashion. The parabolic troughs are made of laminated plywood or molded or formed of plastics or metals. The drive motor moves a flexible belt, i.e., chain or cable, which is routed about the drive ring on each collector. The motion of the cable moves all drive rings together to track the sun. A photodetector senses the position of the sun and provides the signal needed to drive the collectors in the correct direction.

A solar collector-skylight assembly having movable parabolic concentrators wherein, in one position the parabolic concentrators direct solar energy to a collector to heat fluid circulating therethrough to thereby provide a solar heater; and when the concentrators are moved to another position, the assembly functions as a skylight wherein the solar energy is allowed to pass through the collector, to thereby illuminate the interior of a building upon which the solar collector-skylight assembly is mounted.
摘要:
A solar energy collector comprising a collector core located within a longitudinal parabolic reflector and formed of a series of spaced tubes exposed to the direct rays of the sun and to rays reflected by the reflector and arranged in a cylindrical array extending longitudinally to form a fluid path between two end annular manifolds connected at opposite ends of a storage tank located within the array.
摘要:
A concentric solar collector comprises a round disk, an insulating substrate moulded with plurality of concentric parabolic troughs, a reflective plate formed as plurality of concentric parabolic troughs, a coiled absorber pipe, plurality of vertical heat-transfer plates each connecting the coiled absorber pipe and the parabolic trough positioned thereunder and a transparent top envelope. Such a collector can be used to efficiently absorb the solar heat either from direct straight sunlight or inclined sunlight.
