Submerging Computer in HAUSGOLD Universal Oil for Cooling: Conductivity & Open-Loop Systems

Hello, as in the topic.
I saw a video of how the whole computer was immersed in oil.
I was curious and did a small test I took oil HAUSGOLD Universal oil.
I poured a little into the small container (after herring) and put in a computer fan and fed it from a small 12 V / 1 A power supply.
It worked and so I turned off and put everything in the power supply with the cable from the power supply to the inside and the sub-zero in full fear or something will not be destroyed. I turned on and started working.

Now the main question.
Because something like that can be done with distilled water (CLEAN water does not conduct electricity)
But after some time the water can absorb the chemical components from the air and the plates of the hands of the breath, which after a certain time of use or carelessness can become a guide.
The question is, can the oil be the same?
Because if not, a simple computer cooling system / an open-loop cooled component can be made.
What I'm going to do.

Transformer oil is used for such purposes. There was already a forum discussion on oil cooling. Look for.

Hmm ... after reading, but there is no answer there.

Plus that I just used cooking

and I want to use it as the cooling of the whole computer, that there is a set of fans in the top.
As I know, liquid can absorb heat more easily and give it back.
And you do not have to tinker with heat sinks.

I will then provide a schematic drawing.

I testing it like

Oil cooling is nothing new. Transformer oil would be appropriate, has a different consistency and chemical composition than edible. Only is it a practical solution at home? Such solutions are used in industry.

Fun - learning.
In fact, the consistency is different from the transformer one. BUT, heat takes over and gives away quickly!
The only disadvantage is that the heat does not want to go up quickly and you have to move in a small movement.
That's why there's a small fan there.
How these tests will burn up to 500 MHz P 2 will go for the test:]

Food oil has the feature that rancid - that is, decomposes, grows, etc. During the decomposition will form compounds with an acidic and alkaline reaction, and microcorrosion will occur - and here even a small sub-digesting of paths may affect the stability of the system.
I recommend transformer oil - it can be even cheaper than food. And most importantly - it is a tested method, the product tested for corrosion and conductivity, and - it does not decompose and does not stink with decomposition products.

I used to successfully use transformer oil to cool the power amplifier.
The amplifier, despite 250W, did not have radiators, and the whole was placed in a suitable container with oil. The container was sealed and required a small expansion tank. Depending on the temperature, the oil volume changes, which should be taken into account in the case of a closed housing.
The question remains where to get such oil.

Hello.
Do not use cooking oil because rancid, mixed with water (to a small extent), and can be aggressive (creative corrosion). A special transformer oil must be used for such purposes.
It is not known how the individual parts of the computer will behave in the oil: rubber bottoms of capacitors, plastic casings of integrated circuits, etc. (they can dissolve in oil, the oil can get in and change the parameters of the elements).
It's better not to risk unless I do not care about this computer. Of course, many elements would have to be behind an oil, e.g. HDD.
Fans in oil can also be destroyed quickly (overloaded), because the oil is thick. To force the circulation of oil, you would have to use some other agitators, and if you already have fans, you would need to cut the blades of propellers and leave two or three to reduce the resistance.
Greetings.

a fan is not a problem enough for a small one.

Okey, how is cooking oil not good? Where should I get transformer oil? where to ask?

Try to use, for example, oil from electric oil heaters, it can also be one that is used in oil circuit breakers (look in electrical equipment repair shops, etc.)

If you have a plant near Energetyczny, ask fitters.

Hm .... okey

I do not know whether to ask in a near transformer station (I live next to the mine and I have even 3 such)

Ask in refrigeration stores, with parts for air conditioning, with household appliances parts. The oil is flooded refrigeration compressors, for example in home refrigerators.

I'm asking you tomorrow. thank you !
I will write how my plan burned out

I recommend thinking about one thing: how to prevent the formation of a thin oil film on all contact surfaces (memory slots, processor socket, card slots, IDE, SATA tape connections, etc.).

i.e.? what does it mean "thin oil film"

For the first time I come in contact with something like this. And whether my idea is good in principle, that I want to use it as an open cooling system.

This means that a thin layer of oil (the so-called film) can form on the surface of ALL contacts, which will act as an insulator.
ps
Did you have organic chemistry at school? (i.e., that relative to the cooking oil - edible) .. Optionally help herein

The oil will enter EVERYWHERE, creating a thin layer that will be an insulator. How does a friend want to protect ALL contacts from this phenomenon?

Thank you for reading vegetable oil.
or how to connect something, maybe there is insulation between the contacts. or just when I want to connect something.
And is this effect only when you use vegetable oil, i.e. food, and is there something like this with trafocs oil?

Buddy - vegetable oils are a mixture of acids - so please, do not take them into account in your experiment.
When writing of the oil film only thought oils inorganic (mineral).
An oil film may be created when attempting to connect devices immersed in oil - although there is a probability (especially at a weak contact) to create it also with devices pre-connected "outside".
ps
Someone has already done something like that - even the movie

I know I saw you on YouTube with oil from ARO, D which destroyed me.

Okey, I am now looking for oil for transformers or electric heaters OR for refrigerator engines.

I still do not know if the oil film effect is also produced by using special oil for transformers and whether such oil changes its properties during use.

Using every oil.

In the temperature range in which you will work, the changes are very slow.

Hello.
Maybe I'm wrong, but in my opinion the problem of an oil film should not occur here. The fact is that the oil covers the surfaces with a thin layer (even the thickness of individual oil particles), the so-called oil film. But will such a movie be maintained between tightly pressed contacts. Oil contactors are manufactured whose contacts work in oil. There are oil-lubricated contacts in switches in meters of many companies, and there are not big contact pressure pads, low voltages, low currents, and there is no problem.
Greetings.

Remember that this oil will warm up eventually.
It would be good to think about a heat exchanger.

Simple idea.

2-4 fans on one side of the flooded casing (rather the aquarium) and on the other - place for air output.
In the middle only a fan prepared or small to move the liquid up! in the entire aquarium. Possibly, the installation for making bombs in one of the corners should also give some movement.

Liquid motion is not everything - mitsum wrote about heat exchanger - that is, a radiator that will discharge heat from oil to the environment (air). Take into account that for long-term work, it is certainly not enough to transfer heat through the walls of the aquarium (the glass has a low heat transfer coefficient) and the oil-air interface passes through the surface. You need an exchanger with a high penetration rate - a metal cooler (aluminum, copper, silver ( ))

Well, and just a half-submerged radiator in oil will not do the same effect? because the cooler is already have to think over the pump and cable system and cooler (probably from the car)

O my wounds, a little more and you will want to calculate everything )).
In general - in my opinion - an aquarium is enough to experiment - in the long run - you have to count a bit (and work with tools)
Anyway - good luck in experimenting (and I advise you to do it on elements which will not be a shame ).

Hello to you. I am a new user and at the beginning I am sorry for digging up the topic. Has anyone thought about using engine oil ??? It does not stutter, it does not spread out. Only is it not leading the current ...?

I will answer you - no current, but such oils are not cheap and still have such an unpleasant odor. I have seen a few such solutions with this oil, but after thinking it over, I decided that baking oil is the best solution;]
