Solar heat collector and radiator for roof

The Solar Heat Collector & Radiator is a heat collector and heat radiating roof structure, designed for building roofs specifically. It was built to be used in conjunction with solar energy and uses a system of air circulation for increased efficiency. [1] A solar heat collector, or solar thermal collector , is used today to capture solar radiation through electromagnetic radiation with the use of solar hot water panels , solar parabolic troughs , or solar towers . Today many people create their own DIY solar heat collectors, but the inventor William Goettl was the first to design and patent this technology. [2]


William Goettl found in 1977 that many building roofs have heat collectors, often pipes, to warm up water or air for a building. [3]


The Solar Heat Collector & Radiator for Building Roof consists of a U-shaped duct with cross-section, and upstanding flanges . The duct structures between adjacent rafters and provides an intermediate partition of upper areas of rafters. There is also a radiation-transparent convection shield. William Goettl, of Goettl Air Conditioning, patented this technology in 1977 through US Patent Office US4098260. [4] It has been made by other people, dating from 1977 to present day, including the modern model of a solar-powered water heating system designed by the Snyder National Corporation, and a solar heating panel.

William H. Goettl was one of the original members of the Metal Sheet Air Rail and Transportation (SMART) charter. He was an instrumental founding role for the Metal Workers ‘Local Union 359 in Arizona , especially when they were writing their original members’ charter in 1937. [5] After moving out of metal sheet metal work, he invested in the Goettl Brothers Metal Products in Phoenix and Took over as the leading company in 1946. Ten years later, He Was Elected as President of the Air Conditioning Contractors Association . By 1972, Goettl had become the largest HVAC contractor in the United States and started introducing significant patents to the industry. William Goettl filed for apatent for the Solar Heat Collector & Radiator for Building Roof on February 7, 1977 and its patent published on July 4, 1978.
