- a series of pipes or coils through which hot water or steam circulates so as to radiate heat into a room, etc.
- a cooling device of tubes and fins, as in an automobile, through which circulating coolant passes
- any radioactive material or body
- Radio a portion of any transmitting antenna capable of producing radio-frequency energy
anything that radiates; specif.,
- a. A heating device consisting of a series of pipes, typically inside an upright metal structure, through which steam or hot water circulates to heat the surrounding space by radiation or convection.b. A similar heating device based on other technology such as the generation of heat through electrical resistance.
- A cooling device, as in automotive engines, through which water or other fluids circulate as a coolant.
- Physics A body that emits radiation.
- A transmitting antenna.
A body that emits radiation. Radiators are commonly designed to transfer heat energy from one place to another, as in an automobile, in which the radiator cools the engine by transferring heat energy from the engine to the air, or in buildings, where radiators transfer heat energy from a furnace to the air and objects in the surrounding room.
- Anything which radiates or emits rays.
- (automotive) A device that lowers engine coolant temperature by conducting heat to the air, through metal fins.
- (of buildings) A finned metal fixture that carries hot water or steam in order to heat a room.
- (electronics) A type of antenna.

- I need to check the water in my radiator before we leave.
- Effective temperature, as an ideal radiator or " black body ": 6000° abs.
- To regulate the heat it is necessary either to instal a number of small radiators or to divide the radiators into sections, each section controlled by distinct valves; steam may then be admitted to all the sections of the radiator or to any less number of sections as desired.
- Radiators should not be fixed directly on to the main heating pipe, but always on branches of smaller diameter leading from the flow pipe to one end of the radiator and back to the main return pipe from the other end; they may then be easily controlled by a valve placed on the branch from the flow pipe.
- A radiator of this last class can be constructed by connecting inductively or directly FIG.
