Cylindrical solar energy collector
A solar energy collector for utilizing the energy of the sun to heat a working fluid is described. The collector comprises a core conduit having a working fluid inlet end and a closure fit across the other end. A single return conduit is spirally wound upon the exterior surface of the core conduit, wherein the windings are in close lateral juxtaposition but with the return conduit and the core conduit both exposed to direct impingement of solar rays. A transparent tube coaxially surrounds the core conduit. Annular members are positioned at each end of the transparent tube to maintain the spatial relationship of the members and form an annular air insulation zone around the core conduit and return conduit.
