Solar heating device

Abstract

An enhanced solar heating device comprising multiple arrays of lenses enclosed in a housing configured to receive solar rays and concentrate the rays into multiple hot spots located on the outer surface of a water conduit is disclosed. The solar ray collection system is supplemented by a reflector attachment used to increase the solar light fed into the device. The water conduit is configured with multiple sections to increase exposure to solar light and increased surface area for formation of hot focal points.

         5 . The solar device of  claim 3 , wherein the magnifying lenses are substantially circular in shape in an x-y plane, wherein each magnifying glass in an array is attached to an adjacent lens at a rim portion of said magnifying glass. 
     
     
         6 . The solar device of  claim 5 , wherein radii of the magnifying lenses in each array are equal to each other. 
     
     
         7 . The solar device of  claim 6 , wherein a ratio of a radius of a magnifying lens of the second planar array and a radius of a magnifying lens of the first planar array is less than 1. 
     
     
         8 . The solar device of  claim 6 , wherein a ratio of a radius of a magnifying lens of the third planar array and a radius of a magnifying lens of the second planar array is less than 1. 
     
     
         9 . The solar device of  claim 6 , wherein a ratio of a radius of a magnifying lens of the third planar array and a radius of a magnifying lens of the second planar array is less than 1. 
     
     
         10 . The solar device of  claim 1 , wherein the water conduit system comprises water tubes windingly arranged into a floor section and a sidewall section. 
     
     
         11 . The solar device of  claim 1 , wherein the water conduit system is enclosed inside an enclosure having a transparent top and transparent walls. 
     
     
         12 . The solar device of  claim 1 , further comprising a reflector attachment having inner reflecting surfaces, said reflector attachment being attached to a top section of the outer portion of the housing. 
     
     
         13 . The solar device of  claim 12 , wherein the reflector attachment comprises a first surface attached to a circumference of the top section of the outer portion of the housing, said first surface being angled outwardly in relation to the housing side wall, said reflector attachment further comprising a second surface, said second surface being attached to the first surface, said second surface being angled inwardly in relation to the housing side wall. 
     
     
         14 . The solar device of  claim 1  further comprising means for pivoting the housing in a direction of the sun's position.
