All you can do is radiate heat away, there is no real convection in space, and vacuum is a hell of a thermal insulator.

The energy collection might be favourable if you ride close to the day/night terminus, but that means you are now (even with two clusters one on the morning and one on the evening side) on average a eighth of the earth diameter away from any given point on the earth, aka from the consumers of the processed data.

IMHO this is a nice engineering challenge, but lacks real utility, as you are mostly ending up solving problems you would not have if you would build a boring data center on the surface ;)

So for all of the space agencies or the satellite intelligence crowd?

Looks pretty much like a solution in search of a problem.
