nanofluid!

Nah, ya ain't workin' it hard till you need liquid sodium for your cooling loop.

edit: I'm pretty sure that stuff is DEFINITELY conductive.

it is no more so then water. I thought the same thing was was not worried about trying it. after playing with it I see it is not any more so then water.

[gillbot]

yes it is conductive. all Water is conductive. if someone tells you that liquid is non conductive they are lying to you. hehe yeah like Naja said.

there is a thread in the water section also.

here is the thread that got me interested. This is another forum I get on.

Actually water is NOT conductive. The impurities it picks up are what make it conductive. I use pure distilled water to clean electronic PCB's all the time.

[littleowl]

this is a note I got from the guy that sent this stuff to me.

There will be no issues with the nanofluid leaking. If it leaks with nanofluid that means it was leaking with water. It won't mess up any seals. It is no different from pumping water because the concentration is low enough to not affect the density...pumping liquid metal..ie..mercury..would destroy any pump. Nanofluids increase the convective heat transfer coefficient, which increases the amount of heat removed from the chip without affecting the temperatures - meaning you can put more heat into the chip because the nanofluid can get rid of it.

Uhhhh ... liquid sodium is what they use for coolant in nuclear reactors. It is literally liquid metal. It's MUCH more conductive than water.

and like I said open up a full 480V panel board and through a bottle all over it.
even if it is the stuff that is in it that is conductive, I am sure you will not do it because you know you will fry. That makes it conductive. I get tired of that stupid argument.

[D_A]

It's fact, not stupidity. What sounds like a petty distinction to you is profoundly important to industrial chemists.

If there is nothing in it, it is NOT conductive.

no just get tired of the water is not conductive but everything in it is. all though it is almost completely imposable to get the stuff out of it so it is non conductive.
Well without thousands of dollars to do it.

so does anyone have the balls to through it into a 480v panel box.

[memolipd]

does conductivity REALLY matter? I've seen quite a few fried computers because the "non-conductive" coolant they used was actually conducting. I dont think its THAT much of an issue! BACK TO THE NANOLIQUID! i want results!

[littleowl]

Thanks you MEM!!!!!! That is what I am saying LOL

Been there, done that, Nothing happened. We had a water leak at one of my industrial facilities of PURIFIED water used in the manufacture of food items. This water is as clean as clean can get. Someone had to go into a flooded MCC and kill the main before it blew. Guess who got the call and guess who is still here and alive because NOTHING HAPPENED.

PURE Water is NOT conductive. I have taken many electrical/electronic components and submerged them in pure distilled water then dried them out to clean them, They still work fine. Call it splitting hairs if you want but the fact remains, my statement is 100% true.

[karl_eller]

Everything conducts given enough voltage and current. What do you think lightning is? It's air conducting electricity. It's not doing it particularly efficiently (hence the sound and light show), but it IS conducting. If you get good quality distilled water, you can run things like 12v fans and stuff in it easily without shorting the fans out, hence it's not a conductor (at least while it's relatively pure). Yeah, with something like a 480v source things might change, but for all intents and purposes it's an insulator.

not to sound mean but those panel boxes are sealed with a rubber seal. We have it happen at work all the time also. As long as the rubber has not dry rotted then the water never made it in.




we should never have a dead component when we have water leaks

yes everything is conductive, so why is everyone so worried about it all of a sudden???

[Jaco]

What's in this nanofluid ? what makes it so special?
I guess 'nanoparticles'
What kind of 'nanoparticles' . Any more info on that?
There must be a technical explanation why it works better than H20

[littleowl]

There is not really any testing that has been done yet.
he will sent me a message later on and I will post it up as he answers his questions. because he is not a member here.

Yes it has nanoparticles in it. They are so small and light that they flow with the water. As the water heats up they heat up and hold more heat. As they pass through the rad they get cooled back down just like your H2O does. They are so small that the heat blows right out of them. leaving them cool again to pick up more heat.
So in turn you move more heat faster then H2O. But I want Mcoffey or Martin to do some heavy heavy testing on it to see what it can withstand. Like I said I have not done much with it but what I am seeing really amazed me. I know it is not much.

Trust me, they are not sealed at all. This plant was built in the 60's.

Plus, this is the old style siemens gear and they didn't use any gaskets at all. I can assure you the water was in the gear, I worked in there for weeks testing and cleaning after that mess. It was nearly knee deep when I got in there to kill power but not one MCC tripped offline.

[littleowl]

well sorry for being optimistic but our plant was built way back then also and the boxes have been sealed since the early 30's. I don't be leave what I don't see I guess

Well to be quite honest with you, if the gear didnt get wet, then it wouldnt trip. Im an electrician & have worked in many food processing plants. I dont want to argue here, but if the room flooded with purified water, it will pick up contaminants from the floor & thus be conductive. Ever seen a 480v switch go up in flames? I have twice in my life & its not pretty.

ps. i dont want to argue & nor does owl. done deal with me........

Uhhhh ... liquid sodium is what they use for coolant in nuclear reactors. It is literally liquid metal. It's MUCH more conductive than water.

Most liquid metal coolants have the huge problem of needing to stay hot, if the reactor gets SCRAM'd and the rest of the loop cools off it solidifies and needs to be heated, sodium, or lead, or many metallic liquid coolants won't work as the computer won't survive the temperatures, mercury is safe if there is proper ventilation, there is a fountain in france or some european country that runs with mercury...

[D_A]

I know liquid sodium is what we would consider 'hot'. Sorry, I forgot the metallurgist humour alert tags.

I'm not arguing, I don't really care if anyone believes me or not. I know the water will pick up contaminants which is why I had to get in there and kill it. Yes, some of the gear was completely submerged.

I have seen many pieces of gear go up in flames with voltages as high as 1,000Kv. The voltage isn't the problem, it's the available short circuit fault current.

I'm an industrial electrician with experience in food processing plants, petro-chemical, power generation, mining/ore processing, instrument installation/service/calibration and defence manufacturing.
The difference in conductivity is used to measure the dissolved mineral content in a water stream. More dissolved minerals means more conductive in a predictable manner. Similarly less dissolved mineral means less conductive down to where pure H2O has zero conductivity. The required voltage (current is NOT a factor as that's the FLOW of electricity. Once current is flowing it's already ionized.) to break water into ions (H+ and O-) and conduct is 80volts per millimetre distance. Air is much higher.
edit: put another way, pure water has a resistivity of 18.2 MegaOhms per centimetre.

I was referring to the bucket blowing up and causing damage. The damage is caused by the available fault current, not the voltage itself.

I remember using a 12V fuel pump as a water pump, that thing was always fully submerged, and it had multiple exposed contacts, none of the water electrolysis -ed and most people have done the thing where you take a car battery and run wires from it into saltwater, and it makes the bubbles...
