Evaporative cooling does not necessitate an open loop system
replyThe system which runs coolant over the chips can be closed but the part which uses an evaporative system to cool that is still open loop and vents water into the air, no?
replyNope, it doesn't have to be open loop!
replyExample of such a system being used specifically for datacenters: https://blog.vantage-dc.com/2026/04/22/cooling-without-the-d...
Evaporated water is condensed, and in the process transfers its heat into another place that removes it. Another simple example is a pot of boiling water with a lid on it.
The link you cited is not evaporative cooling and a pot of boiling water with a sealed lid on it is a pressure vessel which eventually explodes.
replyIf you were to remove the heat at a sufficient rate by, say, turning the lid into a heat exchanger, you would have a stable system.
replyHow is that different from not using evaporative cooling and just putting the heat exchanger on the burner?
