It is, yes. A large fraction (about a quarter?) of what looks like solar panels on the ISS are actually dedicated radiator panels. The solar panels are angled to face the sun, and the radiators are angled at 90 degrees from the sun, to face empty space.
Inefficient is maybe the right word? If you have more stuff to absorb the radiation I believe you can transfer it faster. So maybe tethering and tossing asteroids or something could be viable?
Isn’t thermal radiation kinda slow, though? It’s basically air cooling, but without air or fans.
