Abstract
A solar heating system includes a solar collector comprising a continuous length of copper tubing coiled into a helical array of closely adjacent turns and supported within a sealed housing. The outer turns of the array are fabricated of tubing having a greater diameter than the tubing which forms the inner turns of the array, and the total length of the larger diameter tubing in the array is greater than that of the smaller diameter tubing. The relationships beween the tubing diameters and lengths are selected to achieve a desired flow rate and temperature rise for the overall array. The array is supported within the housing by copper sheets which also operate to eliminate moisture condensation within the housing.

A solar collector for use in a solar heating system, comprising a sealed housing, one face of said housing being planar and being transparent to admit solar radiation to the interior of said housing, a continuous length of tubing tightly coiled in a substantially flat planar helical array of closely adjacent contiguous turns, means for supporting said flat planar helical tubing array within said housing with the plane of said array being disposed substantially parallel to the plane of said transparent housing face, said array comprising two pluralities of helical turns respectively connected in series flow communication with one another and respectively disposed in concentric, substantially coplanar relation to one another, the diameters of the tubings in said two pluralities of helical turns respectively differing from one another, a flow inlet line connected to the larger diameter tubing one of said two pluralities of helical turns and a flow outlet line connected to the smaller diameter tubing one of said two pluralities of helical turns.
