The heat exchange means comprises a first tubular section that is suitable for being irradiated by the irradiation source and inside which a second tubular section is fitted longitudinally, the duct comprising an inter-space defined between the first and the second section.
Abstract:
A modular, solar energy system comprising one or more modular solar panels. The solar panels include a pair of general planar, plates that are secured together to form a narrow channel therebetween for the circulation of a liquid. The solar panels have header assemblies affixed to opposite edges thereof and which control the entry of liquid into the channel and the exit therefrom. The inlet header assembly has a plurality of nozzles that are adjustable in size to control flow therethrough while the outlet header assembly has elongated nozzles to receive flow or liquid from the channel. The plates are preferably constructed of aluminum and one plate has a photovoltaic cell affixed thereto to face the sun and the other plate has a plurality of indentations that enhance the heat transfer characteristics with respect to the liquid flowing though the channel between the plates.

Abstract:
Disclosed is a system and method for harvesting solar energy, and more particularly an energy-positive sky lighting system that may provide an integrated energy solution to a variety of commercial buildings. A plurality of skylight modules are provided, each having a plurality of louvers configured to reflect incoming sunlight onto a thermal receiver area on an adjacent louver to heat a working fluid in communication with the louvers (i.e., such that heat transfer is carried out between the thermal receiver and the working fluid), all while allowing control of the amount of daylight that passes through the module. The modules are constructed such that the balance of the solar energy not going into day lighting is captured in the form of thermal heat, which in turn may be applied to building system cooling and heating applications.
Abstract:
A solar collector is provided. The collector comprises a monolithic flow control component to direct a flow of the heat transfer fluid between an inlet and outlet; and a solar absorber supported by the monolithic flow control component. The monolithic flow control component is able to support the solar absorber without any additional structural components to lend mechanical strength to the monolithic flow control component.
Abstract:
A solar heat collector (100) is provided which has a plurality of upper air channels (3) arranged adjacently. A first flow control means (20) is provided at a first end of the upper air channels (3) and a second flow control means (20) is provided at a second end of the air channels (3). Each flow control means (20) is movable between a first position in which flow through the upper air channels (3) is substantially prevented and a second position wherein flow though the upper air channels (3) is permitted. Also described are a heat exchanger (100B), a fan (72), and a variety of flow modes.
