why water and not pg or vg solution?

post #1 of 3
Thread Starter 
im sure someone has asked this before, if not here it goes.
why aren't liquid systems using pg or vg (propylene glycol or vegetable glycerin)? they are non-conductive to electricity.
now vg is a much thicker fluid so i wouldn't think that would be a good solution but pg should be fine.
that is assuming that it would have the same cooling ability as water.

As a coolant, water is superior to ethylene glycol or propylene glycol -- or glycerin. The reason why automobiles use 50/50 mixture of water and glycol is for freeze protection. If you want maximum cooling, use pure distilled water. Some people mix a small bit of ethylene glycol or propylene glycol for the anticorrosion additives that are present in the coolants.

Exactly. Water has almost double the specific heat capacity as ethylene glycol. See this chart. The higher the value, the better the liquid is as a coolant. Water is only surpassed by ammonia which is both toxic and corrosive.
