Non-Conductive Liquids: Distilled Water & Electrical Safety at 230V Voltage

Hello, can someone tell me how happy you are will not conduct electricity (230v)
will distilled water work?
Best regards and thank you in advance for your help ;]

100% transformer oil, no water.

Distilled water will also not conduct electricity

where can you get it, what price ??

will distilled water left to external factors (air, sun, etc.) start to conduct? it is a high voltage of 230V so I want to be 100% sure;]

You can buy oil in most wholesalers with electrical (energy) equipment, the price is about a few zlotys / liter. As for distilled water, if it is not tightly closed, it is not clean anymore (dust, dust, etc.), after some time it loses its distilled properties.

The oil, at least the one I use at work to fill the transformers, costs about PLN 7 per liter. As a colleague wrote above, ask in good electrical equipment stores, I also saw offers on the internet. Remember transformer oil is hygroscopic, i.e. it absorbs moisture. You will find some oil (about 200ml) in a bottle-top ignition coil and old oil capacitors - in a metal housing.

Due to its polar nature, distilled water is not suitable for use as an insulating liquid. Without going into detail, after inserting a conductive material into it and applying a current to it, quite quickly some of the electrode material will dissolve, ionize and impart conductivity. In addition, distilled water is an aggressive liquid with a pH around 5 (dissolving CO2 and creating carbonic acid), which accelerates the transfer of the electrode atoms into the solution (obtaining conductivity)
It is possible to retain the properties of water as an insulator, but it is difficult and very gentle. Better to use a different liquid.

Hello. I am the author of the topic (on a friend's account), but as one of the users wrote to me that I would specifically describe what I want to use this isolator for, I set up an account and writes .
Well, I want to use one of the liquid insulators to cool the computer: i.e. flood all computer components - of course, except for drives and disks - when it comes to the power supply, it depends on whether the insulator is suitable for it ... so please provide the best fluid that I could use. thank you in advance and best regards.
ps. I am asking for contact details for a given product.

I read about it somewhere.
Maybe look in the Comps section.

Motorized is enough :-)

In fact, oil, but I do not know the properties of all oils, maybe synthetic would be suitable

However, I read somewhere that mineral oil is the best for such purposes ...

Motor oil, not really. This requires a liquid that absorbs heat quickly and adds heat quickly. Distilled water heats up for a long time and gives the temperature for a long time. On the other hand, the oil heats up quite quickly, but it does not give off heat quickly. Rather, lean towards engine coolants.

Cooling fluids in engines are usually quite aggressive in nature ... too aggressive to cool the electronics. I think that if you use mineral oil and force the liquid to move, it should do the job. The oil hardly evaporates, the heat transfer surface would be quite large, all components would be cooled.

How about propylene glycol.

from the description I read OVER THERE , I would prefer not to have this substance at home ...

The phenomenon of heating and heat dissipation is symmetrical, i.e. the liquid gives off heat as quickly as it heats up (vide -> specific heat)


The video I posted should be treated with a grain of salt in my opinion, although as you can see the cheapest engine oil did its job and the computer worked. The liquid in such a system is designed to transport heat from the hottest elements and transmit it to the housing and surroundings. If the casing was thermally insulated, the computer, despite being flooded with liquid, could overheat.

For this purpose, with normal finances, only transformer oil. From time to time, at computer fairs, a presentation of such a system is shown - I do not remember the name of the company. Also, the topic is not innovative and there were already approaches to it from different angles. You can also try it with a spray preparation, which supposedly after applying a layer to the electronics creates a coating on it that insulates from water and moisture.

Better to give up on it. It's too dangerous a substance to stand right next to me at work.

my friend cools the processor in a similar way ... I will ask him later what he does

I also plan to flood the computer with a power supply in some liquid. Maybe not so much that it has great cooling, because the equipment is worth a few pennies (pentium II 400), but a little for satisfaction and thinks that you have something special at home
In general, there would be a way to flood everything, but I read somewhere on the forum in a similar topic that the disk is not tight, since the disk is not tight and water will get there, how come the crossbow does not get there? A moment ago, I unscrewed the electronics from the disk, it looks like there is one circular tape next to the electronics, the upper metal part is screwed on but through the gasket, the screw holding the heads is under the sticker, the electronics connector is embedded in the plastic, so is the disk not tight?
Somewhere, I had a broken disk and it seems to me that I will have to drown it ;-)

@U.P.
And this colleague above is how much it cools the computer?

With these disks it may depend on the specific manufacturer or even model. For example, I have an old WD disk and there is a ventilation window under the PCB with electronics, glued with a very dense mesh - a dust filter that would surely let the liquid inside.

Each disc has a barometric filter that equalizes the pressure of the air inside the disc can with the pressure of the environment. the barometric filter does not let "garbage" out of the air. but the fluids will certainly let them through. however, it may turn out that the disk, even in oil (but not too thick), will work better than the outside ... but I think that then the top cover of the disk should be removed and then it "drowned" ... it's worth trying
greetings

I don't think my friend thinks about flooding the disc with oil !!! Once they rotate at high speed, even at 10,000 rpm (usually 7200), two heads move at a minimum distance over the surface of the disk on the so-called air cushion, three arm with the head make very quick movements - in oil it cannot work properly !!!

woytekp: will try sometime by the way 10000 rpm, 15000 rpm are SCSI drives only have ... normal (S) ATA up to 7200 .. difficult to judge without checking how it will behave

WD Raptor is 10k rpm and is not SCSI capable.
When it comes to cooling the disk, my colleague probably wrote above not to immerse it completely, but that the side walls (where most heat is emitted from what I remember) are immersed in the liquid.
Besides, probably all drives can work in vertical position.

in the June chip there is a report from the google test on disks .. it turns out that the lower the temperature of the disk, the higher its susceptibility to errors and damage .. warm disks - up to 45 C they have greater durability and resistance ... I recommend the medicine greetings

When it comes to water, it is one of the best refrigerants due to the fact that it has almost the greatest heat capacity, i.e. it has almost the best properties in terms of receiving, transferring and giving off heat. And the fact that it "warms up for a long time and gives back for a long time" is its advantage. greetings
