In a vacuum, radiative heat loss per time hyper scales with temperature to the 4th power.
In orbit large and complex heat transfer systems are not going to be practical. On a surface, specialized heat pumps can localize heat energy to very high intensity. With critical reliability advantages of stability, vibration control, complete sun shading, weaker size constraints, etc.
That is a tremendous advantage that will overwhelm most other details and tradeoffs, because the two main constraints, and operating costs, are energy production and heat dispersion. The latter imposing a limit on the former.
