ABSTRACT:
Open-flow solar heat collectors have been used since 1959 in Thomason Solar House No. 1, similar to those disclosed in U.S. Pat. Nos. 3,145,707 and 3,215,134. Improvements were needed to avoid heat loss, vapor loss, and condensation, near the top and bottom of the corrugated solar heat collector sheet.
In the present invention a transition area or transition section is used to change the collector sheet from its irregular or non-planar configuration to a substantially planar configuration. At the bottom, the irregular, non-planar sheet may be formed to a planar configuration and then shaped to form a collector trough with an outlet for warm water flowing therefrom. At the top, the irregular, non-planar collector sheet may be changed, at the transition area or section, to a substantially planar configuration and substantially sealed to, or adjacent to, the collector glazing material to reduce heat and vapor loss at the top.
