Compressed air is one of the MOST expensive forms of energy in an industrial plant coming in at almost 8 times that of electricity. Watt for watt cooling between a peltier cooler and vortex cooler, the vortex cooler would cost far more money to operate. That said, vortex coolers are still awesome.

@shadowtheimpure

The vortex cooler is optimal for applications where a Peltier would not be appropriate. You can channel the cooled air from the vortex cooler through insulated tubes into a machine while keeping the 'hot side' away. You can't do that with a Peltier, the 'hot side' will always be in close proximity to the machine. If the vortex cooler is constantly running, like it would in an industrial setting, the efficiency loss becomes less and less as the inner tube itself gets down to temperature.

Yep, this thing is insanely inefficient. Napkin math: the vortex cooler is using 12,000 watts of energy to create the 850 watts of cooling. 14.1% efficient! That's not counting the efficiency of the air compressor, perhaps 85%, and pipe loses. McMaster where they bought it lists it next to refrigerant based A/C units, where it gets absolutely stomped. McMaster does not list CoP for these units, but 2 is a safe minimum bet. They would turn 1500 watt wall power into 3000 watts of cooling. The vortex tube would have very niche applications, perhaps where condensation, refrigerant leakage, or size constraints are a concern.

you should attach it to a cpu water block, and leave the other fitting open. I think it will have a much better effect, as it will cool the copper block while allowing proper direction for the air to move.

You mentioned you used "filtered, oil-free air," but largely the problem with a compressor is less likely oil in the air and more likely water. Compressed air alone has *tons* of moisture, so much so that if you put your hand in front of a stream of air right off a compressor (at a safe distance, of course) it'd get damp basically instantly. Your filter is, like many, also a drier. No moisture in the outgoing air equals no water to create frost. Only the outside, in contact with air at typical ambient humidity, forms frost.

You can have dry air if you have a drier after the compressor motor. Negating a rusted out tank. And less purging of the tank. Although I think that having synthetic oil in the compressor tank will help negate rust. But that is not really likely but possible. Though due to the head contractions of the motor mounted on the tank can be an issue. unless it has a thick metal base plate for the motor that sits on top of the compressor. But you are still putting in hot air. Thus reducing your cfm.

2:12 Hot air is not dense, cold air is denser. A vortex tube creates cold air and hot air by forcing compressed air through a generation chamber, which spins the air at a high rate of speed (1,000,000 rpm) into a vortex. The high speed air heats up as it spins along the inner walls of the tube toward the control valve. A percentage of the hot, high speed air is permitted to exit at the valve. The remainder of the (now slower) air stream is forced to counterflow up through the center of the high speed air stream in a second vortex. The slower moving air gives up energy in the form of heat and becomes cooled as it spins up the tube. The inside counterflow vortex exits the opposite end as extremely cold air. Vortex tubes generate temperatures as much as 100 deg F (56 deg C) below the inlet air temperature. The fraction of hot air exhausted can be varied to change the outlet cold air temperature, with more exhaust resulting in a colder cold air stream (with lower flow rate), and less exhaust resulting in a warmer cold air stream (and higher flow rate).

What confuses me is why the slower moving air gives up its energy, as in where does it go? As far as I can tell, the only thing that the slower air touches before it has cooled is the end of the tube where some hot air escapes as well as the outer hotter air vortex, so convection wouldn't be able to cool the inner air stream to lower temps than either of those, which should both be at or above ambient temperature. Is this a refrigeration-like effect because the inner stream becomes less dense somehow? That is the only way it would make sense to me, as it would be like a pressurized tank that gets depressurized and is much colder afterwards. But how is that pressure differential maintained? Just the centrifugal force of the air vortex spinning around? Or is there a physical divider between the two streams that isn't shown in the diagrams?

An air compressor without an air drier still dries the air. Air molecules act like a sponge.

When the sponge returns to its original size, there is less water in it.

doesn't really have anything to do with the size of the tube. The issue is the ability to transfer heat from the CPU efficiently. Just blowing cold air at the heat spreader is suuuuuper inefficient, there is a reason we use coolers with big fin stacks, airs thermal conductivity is pretty shit. The majority of the air is never in contact with the cpu heat spreader for long enough to actually transfer much heat. A much better way to do this is like use a small water loop, just a CPU block and some kind of reservoir, then put a heat exchanger in the reservoir, either just a coil of copper tubing or if you use a largish reservoir you could just submerge a radiator in it. Then have the cold air blow through the heat exchanger, thereby chilling the water. Since the device is capable of hitting subzero temps using a coolant other than water would probably be a good idea, something like an alcohol (isopropyl or ethanol, vodka cooling?) or just an antifreeze additive in the water like some kind of glycol.

In space there's no air to conduct heat away, it can only radiate away.

The way I understand it: Heat is basically the rate/speed a particle/molecule move/shaking. so the outer spiraling vortex is getting hotter because of frictions with the metal that makes the air particle "shaking more". it moves really fast that made it only want stay outside because of the centrifugal. now the neat part is only the outer vortex can go outside of the hot end tube. but now we still have mass flow that cannot escape through the hot end and it will look through the other end. the inside vortex is slower because the high speed air forces to be on the outside diameter. the slower air creates a vortex in the opposite rotation because of the returning impulse effect of the hot end nozzle. the slower vortex/air molecules "crashes" with the outer vortex that made the inner vortex slower and slower. the slower particle that has crashed stays in the most inside part of the vortex while the faster particles move to the ouside because of the centrifugal again. this "speed loss" over time creates colder and colder air

@george-broughton

Translation: The centrifugal force/innertia in the air is the thing creating a pressure difference and thus the outside layer of hot gas where there is high pressure, and the inside layer of cold where there is low pressure. The hot end opening seems to merely exist for the sake of ensuring new gas gets in there and keeps producing a vortex. Otherwise the pressure would equalise quickly and it'd just blow air from the compressor directly out of the cold end. Cooling the hot end tube with heatsinking should further accelerate the cooling effect, however it will reach a critical point where this effect breaks down given enough cooling i suppose. the reason it flows backwards in an inverse helical pattern is because if it were to flow in the same path as the hot end but in reverse, it would have a lot more resistence as it would directly counterract the hot air vortex. Instead it flows perpendicular to the hot vortex in an inverse helical pattern because it's the path of least resistence. An analogy if you will: Turning a car left or right going 60mph down a road is easier than pushing it backwards. am i getting this right so far?

The issue is the heat transfer rate, using the bigger nozzle isn't going to make it cool a cpu better, you need a way to efficiently take the cold air coming from the device and transfer the heat from the cpu into it. Just blowing the cold air at the CPU isn't effective because most of the cold air hits the surface and bounces/flows away after absorbing very very little heat. A better way to do this would be to set up a water block and pump that is just circulating water from a smallish reservoir (bucket or something). In your reservoir place some kind of heat exchanger, like a coil of copper tubing or even just a water cooling radiator. Set up the vortex cooler so the cold air is blowing through some tubing and through the heat exchanger, that way it chills the water which is then used to cool the cpu. Since the device is able to hit sub zero temps using something with a much lower freezing point than regular water would be advisable, an alcohol like isopropyl or even ethanol (vodka or everclear!) would work, or you could use water with an additive like some kind of glycol (basically just automotive engine coolant, anything marketed as antifreeze). The alcohol option would probably be the easiest to clean up and have the lowest toxicity if that's something you care about.

The recycling, steel making and mining industries use these to thermally protect cameras inside of explosion proof housings. They are durable enough for the knocks the housings take, with the side benefit of clean positive air pressure to keep out dust.

I think it'd potentially work if you had a passive heatsink on the cpu, like the things that are just a block with fins. Problem with a the heat pipe / fan radiator could be that it's really good at equalizing with the surrounding air temp, effectively dissipating the cold elsewhere on the fins instead of delivering it to the cpu. You want to maximize the surface area that's being hit by the cold air, but also minimize the surface that could be getting warmed by ambient air and minimize the distance between the temperature extremes.

A similar setup is used to generate either cold or warm air to the protective hoods used in industrial sandblasting.

I was expecting a custom mount made to direct its air for effectively harnessing its dispersion 🧐

When I worked in a factory in the paint department, we use vortex coolers to chill the breathable air supply when we were in the paint booths. made those long runs a lot more bearable!

Also terrifyingly toxic.

The Vortex cooler is amazing I took one apart and its a tube with a plastic flat round thick washer that has grooves in it that are angled so the air spins the washer and last a metal washer with a small hole in the middle. This washer was probably used for pressure increase to the V groove metal part. So basically the setup took the cold out sending it one way and expelled the hot out the end. the air is separated by a bent metal sheet (in a V shape) in the tube. hot air comes out the bottom and cold comes out the top. This unit was for a fresh air breather setup for painting industrial coatings on large Jets. What happened to mine was that bent metal part slipped into the tube and the cold stopped. There is no electricity only compressed air going to the unit. It was not unusual to hang my hood up and come back and the face shield was frozen or on hotter days covered in condensation and very cold. The unit expelled hot air that would burn you. I got it working again once I figured out there the metal part went. The only moving part was the 3/8th inch washer with the grooves into it. Taking it apart was not what I expected on the inside.

4:21 That is an ASCO valve. There is a diaphragm with a spring and plunger inside that is activated by the solenoid which is the black square with the wires coming out of it. The vortex is very noise but extremely effective. I use them for cooling down components that I need to service so we can get then repaired and back into production faster. I also use the vortex to cool myself when I am working in hot areas of the plant. If you take a water bottle and drill a ton of small holes all over and then fill the water bottle with scotch bright or something similar then run the cold air into the water bottle you have what we refer to as a "nut cooler". I stick this device into my pocket while working around hot equipment or I just use the vortex's that has magnets attached to it and aim 2 or 3 vortex's at the work area to cool us off as we work.

Since air acts similarly to a fluid, you should revisit this by directly attaching the vortex output to the inlet of a CPU waterblock (with insulated tubing)!

I have seen these used about 25 years ago at a Staley's plant it was used to keep the electronics cool in a control cabinet. These things use a lot of air.

With regards to your compressed air, you could get a sump tank and feed the lines from that or set it up to use the sump once the pressure drops and the compressor starts up again..

However it does work and it doesn't violate thermodynamics. If you do the calculations the total entropy of the system is increasing even with the separation into hot and cold streams.

I think it works like that : the compressed air is forced into a vortex and doesnt escape at the cool end since the hole diameter is smaller than the diameter of the vortex. Then the valve at the hot end make it so that some air can bounce back in the middle of the vortex (that have less pressure due to centrifugal force forcing the vortex air to be compressed at the surface of the interior walls of the tube) where the bouncing air loose energy by friction with the vortex (think how water flow faster in the middle of a river and slower near the edge where there is friction) and can escape at the cool end because it is now aligned with the hole.

We used one for PHA plastic Biodegradable straws for Starbucks. When we make the straws its extruded out of a die and it goes into a 50ft water filled tank. PHA is very tricky to work with as it has two different materials that like different temperatures to crystallize. One crystal forms in hot water and the other forms in a cold water. So the first 2 feet was 35°C and the last 48ft was Cold water. Then we had an air cooler to help remove water and also cool the straw as quick as possible to make it firm enough to packaged. This process was running at about 700 straws a minute. It did a pretty good job cooling the plastic

But wouldnt that pull in ambient temp air? Which would heat up the airstream

These are known as Ranque-Hilsch coolers. When I was at RPI these were known as Hilsch tubes, then there was an engineering improvement that makes it much more difficult to understand. (That's the Ranque part with the air reflected and the cold air more concentrated.) The Hilsch tube itself is pretty easy to understand. Create a circular chamber with a hole on one side near the edge, and a hole at the center on the other side. Now add a third port that is at the edge of the circular part and blowing at right angles to create the vortex. Like in a centrifuge, the heavier stuff goes to the outside. In this case that is the colder air. I saw one Hilch tube unit for putting in the anchor cable (mooring rope for you not naval types*). For a sailboat, it would provide cooling to a refrigerator and optionally heating to the cabin. (NOT for use in winter climate, but it could extend the sailing season a few weeks on either end. I wouldn't try to put it into any of the sheets--the ropes that pull the lower corner of the sail away from the mast--when the boat was under sail. * Special vocabulary makes things much more concise. For sailing it helps when you just have a skipper and one crew, and makes it possible to manage a ship with hundreds of lines. For example, the skipper is the person holding the wheel or rudder, unless the ship has a wheel with multiple sets of spokes--and people holding them. Then the skipper is the OOD. Note that who the skipper is is very well defined, even on modern ships--everyone within range of the skipper's voice must know the sound of the voices of anyone who might be in that role. Oh, and the call "Captain on the Deck!" should have everyone saluting. But the salutes are not the point, they are the acknowledgment that the Captain is in a position where he may override other orders. Of course, on the bigger ships, this culture is limited to the bridge and the (CIC combat information center).

You need to try to connect this to a water cooler and run the air through the water block or create a mini chill box around the cpu where you can contain the cold air and not let ambient air heat it up.

Maybe try using a water block to increase the surface area the cold air can interface with. You could also design a custom air block with all the equipment you have at your disposal.

I've seen it at my job in a ink room in an electric pannel (alcohol vapors) and it's working good but it's so noisy when the air passing in the hole. You also need a industrial compressor for continuous operation.

The problem arises when the cool end is cold enough to freeze the liquid. The ice can't wick back to the hot end, so all the carrier material piles up at the cold end and the heat pipe process breaks down. At that point, it's no better than a thin-walled copper tube. At low pressures, water consistently freezes at 0°C, so the vortex cooler (which is colder than that) runs the risk of freezing up and shutting down a typical heat pipe. An acetone-based heat pipe won't freeze up until -95°C.

Compressed air is one of the most expensive energy sources. No, you will not use this in an application that is viable for many other and better solutions.

I definitely know that cold air is definitely more dense. Other than that I'm interested in seeing how exactly it works in a real world application!

Vortex tubes are amazing and can change the input air temperature up to 60f or so. These tubes are used on cool vests and in cool suits for sandblasters as well as in steel Mills to eliminate heat injuries on the job. It's amazing and works by separating the hot and Cold air molecules. Kind of like how a large storm cloud sucks up warm humid air and blasts down cold ass air. Also btw. You can get a vortex cooler for like $150

Maybe a video idea for SmarterEveryDay, explaining the vortex tube

Great Video as usual. Just wanted to say thanks for all the great entertainment over the years. Would love to see you shoot the air through a CPU water block with one end open.

When you get "condensation" is not only dependent on temperature, but also pressure. The speed of the "vortex" is creating very large changes in pressure. You're getting temperature changes because of the huge changes in pressure and how gases operate in a vortex. So, you see the condensation on the outside because you don't hit the point of vaporization (condensation) inside. That is assuming it is designed to ensure that you can use standard air as an inlet and guaranteed to not produce water vapor lol.

My work use to do use these to machine medical and food grade parts that could not be touched by hand or use any coolant at all. BTW blender blades are not allowed to be touched by hand but can get minimal water/glycol coolant. That's why the instructions say to wash before you use.

When I was younger I knew about this and was coming up with ways to cool a pc with it. The problem was cost of the vortex tube on top of the constant need of compressed air. It's certainly doable but not the most practical when you figure up the volume of compressed air and how quickly you go through it. With a proper interface however it'd actually work unlike simply directing air towards a CPU lol.

Like some other people have said, just blow it through a waterblock.

I have a vortex . I use it for resetting chokes on automotive carburetors . The hot end can help get refrigerant out of the receiver dryer too. I like your use for it too .

I work on jackup rig in Saudi Arabia and we installed few years ago some Vortex systems on some panels with computers that are exposed to weather and had poor ventilation/cooling. In the beginning I was a bit septic about the system but was surprised how well it works. Still today for me looks magic air in, hot air in one way and cold on the other.

The best thing about this thing is that there's no moving parts in it. Making it somehow even harder to understand the magic.

I think you need to mount this so the hot air vents out the top of the case and you run a tube to a cpu water block with the other end connected to a tube venting out. That would probably be the most efficient way of doing it

I can see where these would be useful anywhere you already have vast reserves of compressed air. Hydrostatic test stations, factories, workshops. These devices are used to freeze pipes.

Ingersol Rand 50 HP rotary vane compressor where I used to work had a radiator the size of one from a compact car, used not simply coolant, but a Lubri-Coolant that was like $125.00 per gallon. We ran two 75 foot long 4 color screenprinting presses with it as much of the mechanisms were pneumatically powered. They print like 4" x 120" banners up to like 300 per hour. Big things. That might run your cooler. :)

1:17 for all you gun nerds. Better get the kit before the AFT hears about it.

I wonder if this would work better if they were to shoot it through the tubes of a liquid cooling system, or even cut some heat pipes open on an air cooler and fire the air through that.

Since the heat pipes are acutally void space filled with water vapor under vacuum, I assume the cold air could freeze the water preventing the wicking from happening, thus lowering the thermal transfer as the cooling would then be forced to occcour in a practically smaller tube (smaller tube >> smaller transfer = less efficient heat transfer). I can also assume that though the colder air was on the die , this had a negligible effect as the surface area used to dissipate heat was significantly diminished. I would retest with a solid aluminum or copper core cooler that contains no heat pipes or vapor chambers. (for the science OFC)

2:45 So, it's like an airconditioner? I vaguely remember it also using pressure to make the air change states, and as a result of that change it releases/uses up energy(heat) thus cooling the air.

Not exactly, an air conditioner deals with changing the state between gas and liquid, one of these doesn't involve liquid; rather something with the movement of the air.

I wonder if sending the air from a cold side to a pipe, then trough a waterblock, with the outlet not connected (not a loop) wouldn't do better. Air is way less thermally conductive, but considering that the flow is way higher and the temperature way lower, it may work out!

Close up the case, seal off all the intake vents in the front 2/3 of it and pipe the chilled air from the vortex cooler into the case. Compare temps and speed with that VS with the case before.

I'm familiar with vortex cooling from my old job, we used them for the paint booth respirators.

We’ve used these at work to cool equipment for years, because the technology is basic and durable, they can last pretty much forever as long as there’s compressed air. As long as we have electricity there’s always compressed air. Although in the recent past, larger equipment gets little air conditioning units, which are much more energy efficient. Those compressed air coolers do get condensation though, so that’s something to consider, would need insulation.

These are often used to cool enectronic enclosures instead of a specific part. You could have cooled the PC case if you blocked most of the airflow into and out of the case. It would basically act like the ambient temp of the room is lower. The outside of the case could frost up if it got too cold, but not the inside. The dry compressed air doesnt contain moisture.

We use those types of coolers at our factory. Just hook them up to an air source and you can get 20 to 30 degrees cooler air than ambient blowing on what you need cooled. Yeah, they are loud AF. We have an industrial air compressor room that is massive that puts about 105 psi through the building. They can get so cold that the condensation will actually freeze in some conditions.

I've always wanted to do this. Thanks

So heat is related to kinetic energy. The air has a random distribution of fast and slow (hot and cold) molecules, and fast moving ones have greater inertia. This greater inertia means that they are harder to turn so bounce around the sides of the tube when the lower inertia, slower (colder) molecules can swirl around in the middle. That's how the hot gets separated from the cold.

@Wise_That

2 жыл бұрын

You could also think of it as the centrifugal force. Due to the high RPM, the outside edge of the tube is at very high pressure and so adiabatically heats up. Since energy is conserved, the gas closer to the center of the tube becomes cold. The hot-end of the tube is designed to leak out only the edge air, so the system always loses heat at one end, and what's left is very cold.
