ABSTRACT:
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.
