2. Radiator (heating) - Wikipedia

   en.wikipedia.org/wiki/Radiator_(heating)

   A radiator is a device that transfers heat to a medium primarily through thermal radiation.In practice, the term radiator is often applied to any number of devices in which a fluid circulates through exposed pipes (often with fins or other means of increasing surface area), notwithstanding that such devices tend to transfer heat mainly by convection and might logically be called convectors.

3. Radiator - Wikipedia

   en.wikipedia.org/wiki/Radiator

   The Roman hypocaust is an early example of a type of radiator for building space heating. Franz San Galli, a Prussian-born Russian businessman living in St. Petersburg, is credited with inventing the heating radiator around 1855, [1] [2] having received a radiator patent in 1857, [3] but American Joseph Nason and Scot Rory Gregor developed a primitive radiator in 1841 [4] and received a number ...

4. Radiant heating and cooling - Wikipedia

   en.wikipedia.org/wiki/Radiant_heating_and_cooling

   The heat energy is emitted from a warm element, such as a floor, wall or overhead panel, and warms people and other objects in rooms rather than directly heating the air. The internal air temperature for radiant heated buildings may be lower than for a conventionally heated building to achieve the same level of body comfort, when adjusted so ...

5. Equivalence of direct radiation - Wikipedia

   en.wikipedia.org/wiki/Equivalence_of_direct...

   Measured in square feet, the reference standard for EDR is the mattress radiator [1] invented by Stephen J. Gold in the mid 19th century. One square foot of EDR is able to liberate 240 BTU per hour when surrounded by 70 °F (21 °C) air and filled with steam of approximately 215 °F (102 °C) temperature and 1 psi of pressure.

6. Plate-fin heat exchanger - Wikipedia

   en.wikipedia.org/wiki/Plate-fin_heat_exchanger

   By providing more contact points for heat transfer to occur, the rate of transfer is increased. This method can be observed in household radiators which maintain a curvy, sinusoidal cross section to maximize surface contact between the heated water inside and the air of a room. In a plate-fin heat exchanger, the fins are easily able to be ...

7. Radiator (engine cooling) - Wikipedia

   en.wikipedia.org/wiki/Radiator_(engine_cooling)

   Once the coolant absorbs the heat from the engine it continues its flow to the radiator. The radiator transfers heat from the coolant to the passing air. Radiators are also used to cool automatic transmission fluids, air conditioner refrigerant, intake air, and sometimes to cool motor oil or power steering fluid. A radiator is typically mounted ...

8. Passive radiator (speaker) - Wikipedia

   en.wikipedia.org/wiki/Passive_radiator_(speaker)

   A speaker enclosure using a passive radiator usually contains an "active loudspeaker" (or main driver), and a passive radiator (also known as a "drone cone"). The active loudspeaker is a normal driver, and the passive radiator is of similar construction, but without a voice coil and magnet assembly .

9. American Radiator Company - Wikipedia

   en.wikipedia.org/wiki/American_Radiator_Company

   The American Radiator company was formed in 1892 from the Detroit Radiator Company, the Michigan Radiator & Iron Manufacturing Company, and the Pierce Steam Heating Company of Buffalo. [ 2 ] [ 1 ] The company was headed by Joseph Bond, (of Pierce Steam Heating Co.), as president, Charles Hodges, (of Detroit Radiator) as treasurer, and Clarence ...
