The present invention relates to a solar collector (1) comprising a containment structure (6) with at least one face exposed to solar radiation, said containment structure (6) comprising a central housing recess (7) and an outer edge (8) that surrounds said central housing recess (7), inside said central recess (7) a primary conduit being arranged for the circulation of a primary heat transfer fluid, exposed to solar radiation, a secondary conduit for the circulation of a secondary fluid, and a heat exchange area between said primary and secondary conduit for the heat exchange between the primary heat transfer fluid and the secondary fluid, said solar collector (1) being characterized in that in at least one portion of said outer edge (8) of the containment structure (6) at least one dissipation conduit (9) is obtained in fluid communication with said primary conduit to dissipate the excess heat to outside said solar collector (1).

A solar collector has an opaque cover heated by solar energy. Heat flows from the opaque cover by conduction, convection, and infrared emittance across a gap within an at least substantially airtight enclosure to an absorber containing a working fluid. The exterior surface of the opaque cover has high solar energy absorptance and the interior surface has high infrared emittance. The exterior surface preferably has low infrared emittance. In one embodiment, fully wetted surface geometry permits direct and reflected infrared absorption by the absorber. The opaque cover eliminates the weight, cost and other shortcomings of glass. A hollow continuous side wall with rounded corners provides an embodiment that is robust yet economical, that is easy to manufacture and seal, that permits a reduced thickness of the opaque cover and mitigates the destructive potential of severe winds, and that can withstand the compressive forces experienced by an evacuated solar collector.

A solar thermal collector adapted to be assembled from a flat pack configuration, comprising a conduit (6) configured to carry fluid and to absorb radiation, a base (1) above which the conduit (6) is mounted and a plurality of panels configured to interconnect with the base (1) to produce a housing (8) for the conduit (6).

Technologies are disclosed herein for a thin heat exchanger through which coolant may be pumped. The heat exchanger may include an envelope and a heat conduction layer provided over the envelope. The envelope may include one or more channels formed therein. The channels formed between the envelope and the conduction layer may extend the length of the heat exchange layer and be configured to carry coolant therethrough. The heat exchange layer may include an inlet manifold on a first end and an outlet manifold on another end opposing the first end. The inlet manifold may allow the flow of coolant into the heat exchange layer and the outlet manifold may allow the removal of the coolant from the heat exchange layer. Coolant flow may be controlled by a suction pump operating under computer control based at least in part on sensor data.

This invention relates to concentrating solar power systems with application of parabolic dish-shaped reflectors.

A proposed CSP module applies a two-phase thermosiphon intended to transport heat generated by concentrated sunlight on a sunlight receiver onto the external surface of a heat exchanging pipe. The outer end butt of a distal plug, which seals the lower section of the two-phase thermosiphon, is provided with a sunlight absorbing coating.

A tracking manipulator is installed below a dish-shaped mirror and joined with its supporting structure; it provides orientation of the axis of the dish-shaped mirror towards the sun.

The walls of the two-phase thermosiphon are provided with a metal vacuum insulated jacket, which has a flexible middle sub-section of its lower section.

Design of the middle and distal sub-sections of the lower section of the two-phase thermosiphon allows accompanied orientation of the distal sub-section axis of the two-phase thermosiphon towards the sun.
