Technically true, but not really. "Radiative cooling" is heat loss through thermal radiation and it's really ineffective. We use air cooling / water cooling for a reason.
Satellites and spacecraft are engineered to make sure they can shed enough heat and they use a fraction of the power a datacenter would. All that energy eventually gets turned into heat, and it has to go somewhere.
It's a ridiculous idea that's never going to make even a tiny bit of economic sense.
