Question about cooling sweepers etc for space

[handyprint]

Hi guys

I would have thought that a radiant pipe touching my sweepers would cool them in a vacuum as they are physically making contact but it does not seem to work. Yet regolith heats them up in a vacuum?

What makes you think they are touching? They are not. Regolith debris will not heat them up for the same reason. Regolith tiles on the other hand covers everything and the tile can't be vacuum at the same time anyway..

Buildings and pipes/wires/drywall in the same tile don't count was making contact with each other, meaning you can only cool buildings surrounded by gases, submerged in liquid, or buried in solids. Auto sweepers can exchange heat with regolith because a building buried in regolith is in regolith, not vacuum.

This mod adds a background tile that ignores the vacuum heat exchange limitations.

You can pump unwanted gas into space and use it in combination with gas valves and drywalls to cool down sweepers/robo-miners/etc. Even 60C CO2 20g/s will suffice for usual sweeper. I hope you're not going to sweep regolith though.

Why not sweep regolith?

But why to sweep?

Because it looks nicer and also feeds my voles.

I prefer keeping voles wild and confined to 1 tile. But if you really want to sweep all that 1000t of regolith supposed cooling 60C CO2 20g/s might be not enough for your sweeper )

I have niobium sweepers, they get cooled by the the same regolith they are going to sweep.

Thanks for clearing it up guys. Just watched a video where someone puts a gas vent and some drywall tiles next to each sweeper to pump cool gas on them.

In my experience it turned out that building sweepers out of nobium is not enough to keep them from overheating. Sometimes no regolith was falling on them for long time and some of them broke down. Rebuilding them using thermium solved the problem.

I haven't run it for thousands of cycles, but it seems to me that if no regolith is falling on them then most of the time they also don't have to run. I have them horizontal, so they are covering 1/3 of the area they can sweep. Obviously the initial batch of regolith is different.

[Angpaur]

That depends on your setup. In mine all sweepers were always involded because I was using automatic dispensers to move all regolith to a central point, where it was dropped finally for futher utlization.
