Evaporative water cooling, desinfecting the coolant

[baloo]

Hi,

In the light of the article/post on evaporative cooling, I'm wondering if H2O2 can be used to "clean" the coolant. Other substances won't work, because of the fumes you'll get...

wadayathink?

what type of coolant are you refering to

[William]

water would be the coolant. Hmm, H2O2. I am not too sure, the peroxide ion is VERY unstable, and will easily break up into H2, H20, and O2, putting air in your system, and wearing itself out over time. I am thinking along the lines of some the anti-algea liquids they use in aquariums to keep algea from growing. HCL would work as it does not eat away copper, but it will react with aluminum and maybe with brass, so it probably wouldn't work. I am going to have to think about it, so far, the anti-algea stuff sounds the best.

i just got it! Chlorine tablets they put in pools, just put in enough for your system, although it could react with copper, who wants to test it out?

so what is wrong with aquarium algecide

[baloo]

H2o2 seemed a good idea because it turns into normal water in time...
Aren't the anti-algae thingies hazardous for your health when they evaporate? That's the main problem, no toxics can be used....

Mmmm maybe I'll also add some esoteric oil...to add a nice smell ti my bong-cooler...

the aquarium stuff cant be toxic can it i mean your supposd to put fish in it right

[Jono]

that stuff is lethal! put some in the aquarium water, then stick your head under the water for 10 or 15 minutes. You'll be dead!

better than dilute hcl

:D

chlorine=bad. buy you could add lots of salt, the salf doesn't evaporate with the water. how corosive would that be?

Aside from then having a very conductive coolant in an electrical appliance? I don't think it would be too corosive...and it would definately be deionized.

[William]

i think chlorine tablets or bleach would be better than salt.

Just get some of the anti-bacterial stuff they sell for evaporative humidifiers. It takes like a 1\4 capful per gallon of water. Look in the humidifier section next to replacement belts and such.

not sure why cholrine would be more corrosive than salt though as both would have chlorine ions in them, just the ones with the chlorine tablets would not be as conductive. I think the anti-bacterial stuff sounds good though.
