IEEE standard P80 is a technical standard of the Institute of Electrical and Electronics Engineers (IEEE), governing outdoor AC substations (although under special circumstances it may also be applied to indoor AC substations). [1] It was last approved on the 28th September, 2017.
Some engines have an oil cooler, a separate small radiator to cool the engine oil. Cars with an automatic transmission often have extra connections to the radiator, allowing the transmission fluid to transfer its heat to the coolant in the radiator. These may be either oil-air radiators, as for a smaller version of the main radiator.
Thermoelectric cooling uses the Peltier effect to create a heat flux at the junction of two different types of materials. A Peltier cooler, heater, or thermoelectric heat pump is a solid-state active heat pump which transfers heat from one side of the device to the other, with consumption of electrical energy, depending on the direction of the current.
Coleman gas camp stove. Throughout its history, Coleman has produced a wide variety of equipment primarily aimed at the camping and recreational markets. A prominent product is the Coleman Lantern, a series of pressure lamps that were originally made to burn gasoline.
The plate heat exchanger (PHE) is a specialized design well suited to transferring heat between medium- and low-pressure fluids. Welded, semi-welded and brazed heat exchangers are used for heat exchange between high-pressure fluids or where a more compact product is required.
A cross section of the aircraft with labeled parts. The XP-80 had a conventional all-metal airframe, with a slim low wing and tricycle landing gear.Like most early jets designed during World War II—and before the Allies captured German research data that confirmed the speed advantages of swept-wings—the XP-80 had straight wings, similar to previous propeller-driven fighters.
Supply chain pyramid. An original equipment manufacturer (OEM) is a company that produces parts and equipment that may be marketed by another company.However, the term is ambiguous, with several other common meanings: an OEM can be the maker of a system that includes other companies' subsystems, an end-product producer, an automotive part that is manufactured by the same company that produced ...
