Heat conduction in vacuum only working selectively

Here's a little theory about heat transfer, note that some things are outdated, but the general idea should be the same - cell-cell vs cell-building vs cell-entity!

1. is perfectly normal - tile-tile transfer, both materials non-vacuum
2. works, because the sweeper actually "touches" the materials, so there is direct contact, this is building-entity transfer(same for pipe-content)
3. Ah, I did this last, now I remember - buildings transfer heat only to their cells => vacuum = no heat transfer behind them.
4. I think this shouldn't work, because vacuum will block the heat transfer between the 2 buildings - Basically they transfer heat to the cell they occupy, but since it's vacuum, no heat transfer happens. So this is normal.

Now I'm thinking how to actually cool those panels/sweepers. I'm levitating around tempshift plates, but they might still not work, since they're basically a building and transfer heat to the cell(vacuum => no transfer).

Another idea might be using liquid. I'm not sure how space works(if liquid will flow down, or up, or disappear), but assuming it falls down, you can drip water on the panels. This should meant that the tile behind the building contains water instead of vacuum and heat transfer will start.

Sweepers might be a bit harder, though, as they're "floating" around, so I'm not sure how water dripping on them works.

Basically heat conduction works "as expected" - when there's direct contact - there's heat transfer. When there isn't - no heat transfer in vacuum.
