With a heatpump the PV and GPU would have the evaporators, the radiator would have the condenser. You do this for two reasons, so you can run the radiator hotter (4th power and all) and because the refrigerant is a good heat spreader (better than pure liquid cooling).
With a heatpump, you don't want a thermal bypass, hence the isolation.
Space is not a great place to get rid of heat, but if you need lots of surface area any way for PV that almost solves itself.
