Heat convector
The heat convector was a piece of energy technology on the Dauntless-class starships.
In 2384, the heat convvector of the USS Dauntless was listed with other rooms, technologies, and systems for engineering in an operations panel on the main bridge. (PRO: "Mindwalk")
A clear view of the panel was provided by Dominique Rossier of Wardenlight Studio. [1]
