Radiator

n. person or thing that radiates; heater made from metal coils or pipes filled with hot water or steam; device used to cool an engine

Radiators and convectors are types of heat exchangers designed to transfer thermal energy from one medium to another for the purpose of cooling and heating. The majority of radiators are constructed to function in automobiles, buildings, and electronics. One might expect the term "radiator" to apply to devices which transfer heat primarily by thermal radiation (see: infrared heating), while a device which relied primarily on natural or forced convection would be called a "convector". In practice, the term "radiator" refers to any of a number of devices in which a liquid 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. The term "convector" refers to a class of devices in which the source of heat is not directly exposed.

1. any object that radiates energy
(hypernym) natural object
(hyponym) radio source
(derivation) radiate
2. heater consisting of a series of pipes for circulating steam or hot water to heat rooms or buildings
(hypernym) heater, warmer
