Very pure deionized (DI) water has low conductivity, and is used in some HV apparatus, mostly because of the spectacularly high dielectric constant (80). It's also used in some clever cooling systems where the anode of the tube is at HV, but the pump and radiator is at ground potential. The problem is that you have to keep the water pure, because it's always dissolving whatever it's contacting. The other problem is that liquid containing systems almost always leak.

A block from the processor has a lot of surface area through which the water flows, so the temperature differential between the water and the block is small compared to other applications of liquid cooling. Hence no issues. -Jack Carrozzo On Wed, Apr 7, 2010 at 3:57 PM, Jonathan Aquilina <eagles051...@gmail.com> wrote: > then if that is a problem then how does water cooling work? > > _______________________________________________ > Beowulf mailing list, Beowulf@beowulf.org sponsored by Penguin Computing > To change your subscription (digest mode or unsubscribe) visit > http://www.beowulf.org/mailman/listinfo/beowulf > >
