  2. Radiator (heating) - Wikipedia

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

    A hot-water radiator consists of a sealed hollow metal container filled with hot water from a boiler or other heating device by gravity feed, a pump, or natural convection. As it gives out heat, the hot water cools and sinks to the bottom of the radiator and is forced out of a pipe at the other end.

    en.wikipedia.org/wiki/Internal_combustion_engine...

    For water-cooled engines on aircraft and surface vehicles, waste heat is transferred from a closed loop of water pumped through the engine to the surrounding atmosphere by a radiator. Water has a higher heat capacity than air, and can thus move heat more quickly away from the engine, but a radiator and pumping system add weight, complexity, and ...

    en.wikipedia.org/wiki/Water_heating

    Water typically enters residences in the US at about 10 °C (50 °F), depending on latitude and season. Hot water temperatures of 50 °C (122 °F) are usual for dish-washing, laundry and showering, which requires that the heater raise the water temperature about 40 °C (72 °F) if the hot water is mixed with cold water at the point of use.

    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 developed a primitive radiator in 1841 [4] and received a number of U.S. patents for ...

    en.wikipedia.org/wiki/Radiant_heating_and_cooling

    Radiant systems are associated with low-exergy systems. Low-exergy refers to the possibility to utilize ‘low quality energy’ (i.e. dispersed energy that has little ability to do useful work). Both heating and cooling can in principle be obtained at temperature levels that are close to the ambient environment.

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

    a radiator, consisting of many small tubes equipped with a honeycomb of fins to dissipate heat rapidly, that receives and cools hot liquid from the engine; a water pump, usually of the centrifugal type, to circulate the coolant through the system; a thermostat to control temperature by varying the amount of coolant going to the radiator;
