My instinct is that mineral oil would be a better coolant than
distilled water, with no corrosion issues.  You can buy it at any
pharmacy, and while it isn’t rated at quite as high a temperature as
transformer oil, it works quite well. I used it in a Cantenna for 30
years! As I recall, it was recommended byHeathkit  as a substitute for
transformer oil.
