    • Radiator (Wireless Teleg) An oscillator.
    • Radiator Any of various devices for cooling an internal substance by radiation, as a system of rings on a gun barrel for cooling it, or a nest of tubes with large radiating surface for cooling circulating water, as in an automobile.

  • Interesting fact: The word "laser" stands for "Light Amplification by Stimulated Emission by radiation."
    • n radiator Anything which radiates; a body or substance from which rays of heat emanate or radiate.
    • n radiator A part of a heating apparatus designed to communicate heat to a room, chiefly by convection, but partly, in some cases, by radiation. A common form of radiator is a sheet-iron drum or cylinder containing deflectors or baffle-plates, placed over a fireplace to cause the volatile products of combustion to give up their heat as they pass: a heating-drum. A steam-radiator consists of a mass of coiled or flexed pipes to which steam for heating is conveyed through a continuous pipe from a boiler, and which is provided with suitable valves for the control of the steam.
    • n radiator Same as cooler, 2 .
    • n radiator In the transmission of electric waves, as in wireless telegraphy, an apparatus for the emission of electric oscillations; a form of oscillator.

  • Interesting fact: Earth's magnetic field has been weakening. It seems to have lost 15% of its strength since 1670. At the present rate of decrease, it will reach zero in 2,000 years. Between the years 3500 and 4500, the magnetic field will not be sufficiently strong enough to ward off charged radiation from outer space.
    • n Radiator a body which radiates or emits rays of light or heat: a part of a heating apparatus for a room
