Cooling the liquid in the reservoir.

[Robinzon]

There is a liquid tank in which the liquid is above the evaporation point. When leaving the tank, the pipe breaks. The structure is in a vacuum. How can you cool the liquid? It's a shame to lose liquefied oxygen.

The best solution I can come up with is running LOX through a conduction panel. until you get the temperature well below the vaporisation point.

I assume by liquid tank it means you're using a liquid reservoir . Liquid reservoirs exchange heat with the tile they're sitting on, so you can either cool the tile till it reaches the liquefaction point of oxygen, or abuse the fact that liquids will not state change if you limit the amount flowing through the pipes to 1kg/s with a liquid valve.

You could pump same liquid but at lower temperature into the tank. It would gradually drag down the overall temperature of the same liquid. It is a slow process and it require a lot of unused capacity, but it is mostly the safest.

I'd to add that building said tile out of mesh tile (the one that allows liquids thru) would make it also heat proof as the tile is considered in vacuum as well. Just make sure there are no debris around.

Is the liquid actually above the evaporation point? I'd be curious to see that. Maybe I didn't know that it won't break a tank.

I thought normally this problem is because the pipe is too warm. You should be using insulating pipes, but they still heat up from their environment, just more slowly. So you'd want to cool the surroundings, probably focusing on the pipe area, but all the area should get cooled.

In vacuum this shouldn't be AS necessary, one the oxygen breaks the pipe a few times, the pipe should be cooled down. But a meteor will heat even an insulated pipe. Vacuum is best for these situations, but not perfect.

Also remember you can debuild then rebuild to reset the item to average temperature, which can be useful if the temp of the item (pipe) is too far from where you want it to be. For example if the pipe had gotten too hot. But doing this for an almost cold enough pipe would hurt you not help.

Best solution hands down. Depending on how hot the liquid you want to cool, you just need to get the liquid inside the reservoir below the vapor temp + 3°C

I'm quite curios to know how did you manage to do it in the first place btw. There's no practical use, I'm just curious.

The oxygen temperature is -154.6, and the evaporation point is -183. I have insulated pipes, partly made of ceramics, partly of Insulite.

I had some of the insulated pipes made of igneous rock. I think the oxygen heated up on the way to the reservoir. I have no answer as to why the pipes didn't break before they got to the reservoir.

it's sitting on regular tiles which exchange heat with those tiles and the stored liquid so when it exits, the liquid instantly vaporized. It will fix itself eventually if you keep repairing but maybe replace with a insulated tile below it or a mesh so heat exchange cannot take place with the contents of the tank.

The only way to recover the liquid is to get the tiles below it even colder than the stored liquid and wait until the liquid is actually a liquid again. Probably put aluminum below it and then super freeze it so you won't have to wait as long.

Ok it looks like you have enough room to pump enough colder LOX to bring down the temperature.
You will need the same mass of LOX cooled to -215 deg celsius.
The heat you need to remove is 33.282 MJ.
The SHC of LOX is 1.01 kJ/(kgK)
But you need to prevent the added LOX from being over the vapourisation point so you need to have it considerably colder than that point. Of course the temperature of the LOX you use of the material will affect how much you need to add as well as what you use to cool it down enough.

The tank will average the temperature of any new LOX going in with what is already in there.

It is also best that you use mesh or airflow tiles under the tank to eliminate heat transfer to the suroundings.

Edit just notice youre using super coolant in your pipes.
