Yeah, heat dissipation is surprisingly difficult in space, because the only real way to do it is via radiation. And radiation is one of the least effective methods of dissipating heat.
The vast majority of heat transfer on earth happens via physical contact, in the form of fluids or solids touching each other. That’s what a heat sink is for. It increases surface area, so more fluid (air) can touch it and carry heat away. But without some sort of fluid contact, a heat sink isn’t going to help much. It’ll act as a radiator, but the cooling efficiency will only be a fraction of what is achieved via traditional forced air cooling.









I mean, that feels a little like saying “Andrew Jackson’s plan wasn’t to kill all native Americans. He just wanted to deport them across the country. Then things just got worse and worse, and now the only thing anyone remembers about that deportation plan is the Trail of Tears.”
