Unfortunately, not, because water is very corrosive, and easy gather many non-inert substances just from air.
This is very serious problem. I once talked with old support engineer from USSR, who have some experience with old water-cooled computers.
And he said, it was just nightmare, all those pipes periodically leak (some because rot, others become fractured) and in many cases, if water reach pcb, its broke.
Really problem was solved on Cray-2 (and later models) by use Fluorinert, which was so inert that was safe to literally drop boards into liquid.
Some persons even thinking, Soviets Elbrus was not successful just because USSR don't have companies like DuPont or 3M to produce something similar to Fluorinert.
- simne 2y agoExists sea grade of electronics, which are covered by thick coating layer, but it is also non-ideal solution, could become fractured, and you cannot make coating on dip switches or on connectors.
- wbl 2y agoFluorinert was absolutely something the USSR could produce. You need fluoromers and fluorine chemistry for nuclear technology.
- simne 2y ago> Fluorinert was absolutely something the USSR could produce May be. But in fact - not produced. And Soviet Elbrus computers used water cooling with extreme problems. - I'm 100% sure, if it was possible for Elbrus designers to use Fluorinert, it would be used, but it was impossible, so not used.
