Solar collector
A solar collector has a galvanized steel, inverted heat pan having a flat plate top and depending sides encasing the sides of typical insulation along the bottom of the plates. A continuous copper tube on the upper face of the plate is of generally serpentine configuration with ends of adjacent runs connected by return bends. The runs are slightly inclined horizontally so that any moisture collecting on the plate flows to the bottom of the normally inclined plate and is discharged. Also, cool water entering at the bottom of the tube moves upwardly through the inclined runs as it is heated, and through an outlet at the top of the tube. Lead strips are preferably provided between the copper tube and the galvanized plate to prevent deterioration by electrolysis between the tube and the plate. A transparent dome has sides which overlap the plate sides and are secured thereto in a manner permitting passage of air into and out of the dome and thus maintain substantially atmospheric pressure within the dome. The transparent sides and beveled side edges of the dome permit greater exposure of the heat plate to solar energy during early and late daylight hours.
