Their white paper touches on the issue, which seems slightly hand-wavy without much detail on quantification. They could potentially take advantage of heat gradients from deep space and dissipate heat to explore the Seeback effect.

In LEO, pointing at deep-space just means away from Sun/Earth. You don't have to be in deep-space to use it for radiating heat away.
