A radiation concentrating solar energy collector and a dual axis tracking support system which positions collector units to receive the maximum incident solar radiation are disclosed. A system of pressurized air is utilized as a multiple function medium which activates the tracking mechanism, inflates and supports the reflective concentrators and acts as the heat transfer medium. |

DETAILED DESCRIPTION The basic unit in the solar energy collection system of this invention is a relatively small reflective type concentrating radiant energy collector mounted to track, i.
e.
point at, the sun by movement about an azimuth and an elevation axis following the sun's daily movement.
Preferably, a plurality of the collector units are mounted in an array for concurrent tracking about one common elevation axis, whereas each unit moves individually, but to the same extent about its own one of a plurality of parallel azimuth axes all generally perpendicular to the common elevation axis.
In the presently preferred embodiment of the invention the common elevation axis is an insulated pipe which also serves to carry the collected heat from the collector units to its end use and the collector units are mounted in pairs, above and below this pipe, to pivot about an azimuth axis perpendicular to the pipe axis.
The system can include a plurality of horizontal insulated pipes arranged parallel and connected to a common outlet and a common source of pressurized air.
Several alternative constructions for the individual collector units are shown, all of which have a cylindrical reflector to concentrate the radiant energy upon an internal heat transfer plate.
The individual collector units are intended to be relatively inexpensive yet durable and easy to maintain.
Air, supplied by a blower at superatmospheric pressure, serves to supply power to the tracking mechanisms for both the elevation axis and the azimuth axis, serves as the support medium for the reflective film concentrators and serves as the heat transfer medium carrying the heat from the collector unit to its end use.
The pressure of the air is regulated as it enters the collector unit and the flow of air is regulated in accordance with temperature as it exits the collector unit.
These and other features and advantages of the solar energy collector of the invention will be more fully understood from the following description of the preferred embodiments of the invention, especially when that description is read with reference to the several figures of the drawings
