Reference excerpt

A solar heat collector and radiator is a heat collecting 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. 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.

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

Design 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 between upper areas of rafters. There is also a radiation-transparent convection shield above the cover plate to stop heat being lost air movement. William Goettl, of Goettl Air Conditioning, patented this technology in 1977 through the U.S. Patent Office with patent number US4098260. It has since been cited by five other patents and referenced by twenty-eight other patents, 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 by Solar Shelter Engineering Inc.

History

William H. Goettl was one of the original members of the Sheet Metal Air Rail and Transportation (SMART) charter. He was an instrumental founding role for the Sheet Metal Workers’ Local Union 359 in Arizona, especially when they were writing their original members’ charter in 1937. After moving out of sheet metal work, he invested in the Goettl Brothers Metal Products in Phoenix and took over as the company leader 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 a patent for the Solar Heat Collector & Radiator for Building Roof on February 7, 1977 and his patent published on July 4, 1978.

Worked examples

Example 1 — a first encounter with Solar heat collector and radiator for building roof

Start with the simplest possible case. Write down what Solar heat collector and radiator for building roof claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Solar heat collector and radiator for building roof before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Solar heat collector and radiator for building roof ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Solar heat collector and radiator for building roof

In research: Solar heat collector and radiator for building roof appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Solar heat collector and radiator for building roof in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Solar heat collector and radiator for building roof is common in secondary-school and first-year university syllabi. It links to neighbouring topics Heating, ventilation, and air conditioning, Solar energy, so understanding it makes those chapters shorter.
In everyday life: Look for Solar heat collector and radiator for building roof outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
