Radiators are heat exchangers used 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. The radiator is always a source of heat to its environment, although this may be for either the purpose of heating this environment, or for cooling the fluid or coolant supplied to it, as for engine cooling. Despite the name, radiators generally transfer the bulk of their heat via convection, not by thermal radiation, though the term "convector" is used more narrowly; see radiation and convection, below.
The Roman hypocaust, a type of radiator for building space heating, was described in 15 AD. The heating radiator was invented by Franz San Galli, a Polish-born Russian businessman living in St. Petersburg, between 1855 and 1857.
One might expect the term "radiator" to apply to devices that 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.

Goodbye humans, goodbye earth
I've left this place and all its worth
I am transcending space and time
I'm traveling at the speed of light
Affection, reflection
This is the new direction
Conspiracy is idiocracy
I radiate light's transparency
[Pre Chorus 1:]
Generation
Radiation
We are the chosen nation
[Chorus:]
Hey you, you're blowing my mind again
Out of my skull, I feel the levitation
I feel my skin crawling off of my soul
I feel your radiation
[Tag:]
I'll be a radiator just like you
Radiate it on me, burn it on through
I feel the radiation
Radiate it on me
[Verse 2:]
Hello future, hello birth
This is your newborn universe
There is no longer wrong or right
We have become a source of light
