An improved solar energy collector has a twisted expanded metal/bristle fin combination structure which provides improved energy absorbing efficiency, good peripheral stability, and efficient heat transfer capabilities. The structure is normally formed by wrapping and thereby expanding, a lanced sheet metal about a conduit in a spiral fashion. In the preferred embodiment, the outer peripheral structure presents a series of protrusions wherein every other protrusion is twisted at an angle with respect to the spiraling structure. |

DETAILED DESCRIPTION The present invention provides a solar energy collector in the form of a bristle fin type of structure.
The structure is especially intended to be wrapped or otherwise disposed about a conduit and in heat exchange relationship with the conduit.
In such an embodiment, fluid flowing through the conduit may be utilized to remove heat absorbed on the bristle fin structure.
The solar collector structure may be fabricated from materials other than sheet metal and by methods other than wrapping on a conduit.
Synthetic polymers, for example, can be fabricated directly into the solar collector structure, without the need for wrapping, and these can be secured to a conduit or flat plate or other structure, as required by the proposed solar collecting device.
Similarly, metal can be molded to form the structure directly, or sheets of metal can be directly punched and twisted to form the solar collector structure for use as required.
The use of lanced sheet metal, which is expanded by wrapping it on a conduit, is intended only as an example of the presently preferred manner of practicing the present invention.
The solar energy collecting structure will normally be fabricated by providing appropriate slits and folds in a piece of sheet metal and thereafter expanding the structure by wrapping the sheet metal about a conduit.
The expanded structure comprises a plurality of elongated leg portions spaced apart from each other and forming a row; and openings formed in the spaces between the spaced apart leg portions which openings have tab portions extending radially therefrom forming a row coincident with the row formed by the leg portions.
The tab portions are twisted at an angle to the row of leg portions.
When this structure is wrapped about a conduit, the leg portions will define a spiral surface and each tab portion will pass through the surface and extend to either side thereof.
As is the usual practice with solar energy collectors, the structure should have a darkened surface to enhance its absorption of solar energy
