I truly have enjoyed all the ways you have said 'water'. In a previous life I
worked with water cooled power cables. We had to work very hard to keep it
pure dihydrogen monoxide because it does have this nasty habit of picking up
stray ions. Pure hydrogen hydroxide does not conduct electricity, but you get
some ions floating around in there and nasty things tend to happen.
I don't think IBM has the problem with hydric acid coming in contact with
conducting material as we did. We had 5000 amps at 600 volts DC running
through cables that were basically fine stranded copper immersed in water in a
rubber hose. Water went in at about 40 degrees at one end and came out 100
feet later at about 70 degrees. We could take the water that went out the
positive line and route it back through the negative line because it was so
pure.
I don't believe! I know pure H2O is dielectric, but it is virtually
impossible to keep it so clean especially in contact with metal (I
assume the conductors were metallic).
So I think, the water had to be *isolated*. That's all. I saw some study
of cooling power generator conductors (22kV, ??kA). Tubes (skin effect).
The goal was to have the liquid circulation insulated. It is feasible
even assuming fill up.
Regarding to "z11" water cooling: what's wrong with water cooling???
Why should we be ashamed of water cooling?
Is it old-fashioned? Dino-like?
Really? Look at newest graphic cards and CPU in PC game high-end boxes.
They almost require liquid cooling. Liquid cooling means hi-tech
nowadays. "The most sophisticated" (sales pitch quotation) rack
solutions are water-cooled.
