How are they solving the heat dissipation issues?

  From the article itself, sounds like it’s an open problem that they are experimenting with:
  “ We’re working on a number of different approaches for this, including a combination of heat pipes and radiators to cool the chips. So far, our team has tested the technology in a thermal vacuum chamber that simulates both the thermal and vacuum environment in space. We’ll see how our new TPU cooling system works in space and refine our designs as we learn more.”

    Imagine a heat pump circuit fails (solar rays? micrometeorite? random chance), I guess everything in that loop will just be dead forever? I guess you don't need to pay to dispose of it.
