The Radiator is a decorative module used in construction
and maintaining of space stations. It has three docking ports, thus two other modules may be connected to it after it is docked into position. It is commonly connected to other Radiators.
It is one of the few game modules that has moving parts. Its three "cooling arms" open upon activation and close when shut down, like the different types of Solar Panels.
It serves no actual function in the game, as of Version 1.8.4.(1.8.9 for android users)
- In actual spacecraft, Radiators are used to remove excess heat from space vessels, which prevents them from overheating and allows them to maintain a constant and comfortable inside temperature for the crew members.
