<p>A solar collector includes two concentric spheres or hemispheres, the outer sphere or hemisphere being translucent or transparent and the inner sphere or hemisphere being absorbent of the solar radiation. Fluid to be heated is conveyed by an inlet duct in which is inserted a pump, and sprayed by a head in an inner spherical or hemispherical chamber defined by the inner surface wall of the inner sphere or hemisphere. It flows along this inner wall, becomes heated during its passage, is collected at the base of the inner sphere or hemisphere by an outlet duct. The collector is particularly adapted for the production of hot water to heat swimming pools and the like. In its hemispherical form, when placed at the top of a support post, it can be associated with a mating hemispherical, translucent or frosted housing which houses a light bulb. In this form the structure functions as a street lamp or the like.</p> |
