Would heat sinks work in space?
Would heat sinks work in space?

Because there's no air going over them
Christian Fisher
Kind of but not really. Massive radiator vanes might be effective, but the shit in OP is worthless.
Joshua Watson
Oh yeah ok, that makes sense
How effective would it be though, just radiation? I suppose if they were big enough....
David Morris
was memeing, i dont know lmao XD

They will also sublimate/evaporate a bit (which might be significant depending on the material and temperature). That might be useful for short-term mission.
Ian Williams
You need heat sinks in space
Grayson Rogers
Yes but without atmosphere the only transfer of energy is radiative.
The thermal exhaust port of the Death Star (Rogue One was never necessary to explain it) works because the interior of the Death Star has an atmosphere. If you blow air out into space you'd be transferring the heat by convection.
Justin Gutierrez
It probably does radiate the heat away
IIRC, the author of the above page is big on excess heat being radiated as neutrinos
Adam Brown
Example of what real heat radiators would look like.
