Chart Showing solid Stat Fan vs. Traditional Fans  (Source: Thorrn Micro Technologies)
Researcher says the solid-state fan is the biggest improvement in cooling since the heat pipe

Many computer enthusiasts understand that how fast a processor runs is in part dependent on how well the chip can be cooled. This is why record-setting benchmark runs are typically made with processors cooled by exotic means.

Cooling is just as important for mobile systems like notebook computers and other portable electronics. The size of the fan required for the system can affect how small devices can be built. A pair of engineers from Thorrn Micro Technologies Inc, Dan Schlitz and Vishal Singhal, have developed a new solid-state fan that works similarly to household air purifiers.

The resulting fan is the most powerful and energy efficient fan of its size and moves more air than fans that are 35 times its size. The RSD5 solid-state fan is described by Singhal as, “One of the most significant advancements in electronics cooling since heat pipes. It could change the cooling paradigm for mobile electronics.”

The device operates thanks to a phenomenon called corona wind. This corona wind is created by placing a series of live wires within uncharged conducting plates contoured into half cylinders, partially enveloping the wires. The live wires generate micro-scale plasma that conducts electricity.

The corona wind is created within the intense electrical field that results from the configuration of the wires and the conducting plates. The researchers say they were able to control the micro-scale discharge to produce maximum airflow without risk of arcing or sparks which could prove catastrophic to electronic devices [Video].

Schlitz says, “The technology has the power to cool a 25-watt chip with a device smaller than 1 cubic-cm and can someday be integrated into silicon to make self-cooling chips.”

MSI has also been working on more efficient ways to cool electronic components as well. DailyTech reported in February that MSI had announced a new ECOlution chipset cooler that operates on the Stirling Engine Theory.

My laptop crashes hard (corrupted video, lockups, etc) if I have it in a smallish room with an "ionic" air purifier going. Within 5 minutes if it's sitting only a few feet from the purifier.

I would hope that the researchers thought of how to get the charged air out of the system harmlessly when they invented this new cooler, but if not it seems potentially useless.

Humm, now that I'm reading that, that could mean that it has a huge power requirement (even though it uses power more efficiently). I guess this all depends on scalability, if these things can become sufficiently small without sacrificing air movement.

Very cool indeed, but what about dust buildup on those tiny holes?

You could design the device so that it was easy to get to this fan and give it a cleaning though.

Very interesting, I wonder if it only works for tiny fans like the one in the picture or if it could work a full sized fan.




RE: What about dust buildup?
By P4blo on 3/20/2008 7:49:42 AM , Rating: 4
I'm thinking that the way these solid state fans work would actually reduce or maybe even remove the dust buildup. I'm not a scientist but here's why I think this.

The primary reason that dust manages to build up on conventional fans and heatsinks in computers is because there is a very thin layer of air right on the sirface of said heatsink or (to a lesser extent) fan, that is barely moving or stationary. It takes fairly stationary air to allow dust to settle and stay still. Sure the air just above this sirface may be blowing at some speed but should the dust cross into this layer of slow moving air it will still settle, regardless.

Now if you take this solid state technology, it's whole reason for being and it's cooling mission in life is to ensure that there is no small layer of stationary air on the coolers sirface. This is how it achieves such efficient results over standard cooling.

Surely if the sirface of the cooler is constantly in such fast moving air, dust cant settle?

I think it will actually prove simpler to keep these things dust free. Most of the dust will just pass through instead of settling.

I think dust buildup is going to be a serious problem. After all, this is the exact tech they use to make the dust filters everybody's talking about. The particles get charged moving past one electrode, and stick to the opposite part. So, while a desktop will be a pain in the shorts to clean since it'll have to be done so often, what about laptops that take a jeweler's tool set along with the dexterity of a surgeon and the patience of a saint to disassemble, rework, and reassemble? It would probably only be a matter of days before such a cooler would not be a cooler any longer.

Pressure - Velocity graph...
By ninjit on 3/19/2008 4:35:35 PM , Rating: 2
Can someone with better fluid-dynamics knowledge explain that graph to me?

I'm not quite sure how Pressure comes into play - I would have though rate of heat transfer would be a function of volume of air moved /s, and hence directly related to air velocity for a given cross-sectional area.




RE: Pressure - Velocity graph...
By MatthiasF on 3/19/2008 4:58:08 PM , Rating: 4
The first thing that threw me off was the fact there are three variables being used on the chart, not only two as assumed by the two axis.

The area of each fan (25x25x10 or 15x15x2) is being multiplied by the pressure at each velocity to create the line which is the mass flow rate.

From flow rate, you can take ambient temperature, heat produced, etc. to calculate out how well it can cool.

Seeing how much electricity is used at different flow rates would be a nice comparison of efficiency between the corona wind and mechanical fans. I'm pretty sure the corona wind scenario will be a lot less efficient.


RE: Pressure - Velocity graph...
By vgermax on 3/19/2008 5:11:16 PM , Rating: 5
The nominal flowrate is typically listed with zero back pressure. As greater back pressure is applied, the fan will have correspondingly lower flowrates. Simply put the fan blows the most air when there's no blockage, the greater the blockage the lesser the flow. Pressure is a measure of how much force/area is required to push through/around the blockage.

I teach Fluid Mechanics and also Transport Phenomena (heat and mass transfer) at a major university. Hopefully I can help ;) I'll try to explain in very lightly worded terms.

If you want the gist, read the next two paragraphs only, skip the rest of my ramblings...

point to graph: higher velocity means better cooling. Don't read any more into it than that. This graph is a energy curve associated with any energy-to-flow machinery (fan, pump, etc...) it in laymens terms says "for a given fan (lets pick the red dotted line) to supply a certain flowrate of air(lets pick 1 m/s on the x-axis) the fan will give you a certain pressure reading (graph shows about 13 Pascals pressure)if you put a gauge on the outlet."

I saw someone mention "back pressure" and he is correct. Imagine this being a pump pumping fluid through a pipe, and you had a valve on the outlet. As you start to close off the valve (lower the flow of fluid... trace your finger left on the graph along one of the fan lines) the pressure inbetween the pump and the valve will go up as you build up back pressure. Reversing this, is opening the valve to it's fullest, you let off pressure. Eventually you reach the maximum theoretical limit of zero "back pressure" meaning that the air is flowing so fast that the molecules don't even press on the spring in a gaugh (zero pressure) and this is the maximum flowrate you will get. Pressure drop causes a flow. But at zero pressure, there is no more room for you to essentially lower the pressure anymore, to increase the pressure drop so a maximum theoretical flow will be obtained. The mechanical system integrity determines thhe parameters on the graph, by being designed to minimize "bad" aspects of energy conversion, i.e. friction, or entropy.

Summary, this graph emphasizes that the solid state fan is worse at lower flowrates than conventional fans (at a given pressure it produces less flow) but as science kicks in, the phenomena they are exploiting overtakes where conventional fans top off and becomes more effective, producing higher flows. The lines cross at around 1 m/s and 15 Pa. Now I ran some quick calcs. This graph ONLY shows
a 40mm fan as the maximum testing case. We all use cooling means better than this for our processors, and cases for sure. The 80mm tricool fan pushes 32.5 cfm of air at max voltage (doing the math this is 2.39 m/s) putting this on the graph as being comparable to the power of this solid state fan. However, the operating rate of mechanical fans is never really on the highest flow end of the curve, rather the best efficiency point (BEP) which gives the best energy-to-flow operating point (which is somewhere in the middle)

what i'd like to see really is the efficiency curve that's usually on graphs like this. Sure you may push more air, but at what cost? It could take more electricity to fuel the solid state fan than a conventional fan to push the same air. This company however, to me, and according to this graph is pushing to prove that it's better on a SIZE OF THE FAN basis. Which in that case, yes, is very true. This thing pushes the same velocity of air as an 80mm case fan at it's max theoretical flowrate, and is the size of a quarter.

Problems I see with this:
1) Noise. That much velocity with a smaller enclosure means NOISE. Test... blow air through a milkshake straw, then a coffee straw with the same force. You don't want to have to hear your girlfriend on the cell phone over that whoosh, then again, you might want to drown her out if she's being naggy ;)

2) Ozone. Electric fields causes ozone (O3) to form from radicalization of O2 in the air. It smells bad, like a nasty burnt smell, and is bad for you...

3) BEP. The best efficiency point is not mentioned here, therefore you have no idea where they plan to operate this thing to optimize it's energy utilization. Sure it can pump out 2.5 m/s of air, and be the size of a Ritz cracker, but in a laptop, and at poor efficiency, could drain your battery like there's no tomorrow. My guess is that anything electrical is more efficienty relatively than anything mechanical, because mechanical friction (like in a rotating fan) is always a big energy eater. But we shall see...

4) At hotter temperatures, air cooling still won't cut it for your high end computational needs. You don't want all that noise, ozone, and well, convective heat transfer coefficients of air still can't compete with the amazing conductive power as well as SILENCE provided by other methods, like TEC's, or copper blocks in liquid cooling systems. (testing this) Take anything that's hot, like a frying pan. Let it sit under a high powered desk fan to cool. Yea, sure that cools it fast. But also, you could just throw that bad boy into a sink filled with water. Which do you think cools the pan faster? ;)

The applications for this is not going to be cooling your 32-core Intel QX 66Million in 2015, but in my opinion, it's better than having NO FAN at all in something like a cell phone as long as you operate at lower flow rates (no noise, lower ozone, as well as keeping things small). I hated when my old razr would literally burn my face. But it's not a trade off to save my skin, if I get cancer from Ozone poisoning.

To understand flow and pressure further, there is the a relationship, thanks to Newton. look up "newtown's second law" "momentum conservation" or a simplified frictionless version the "bernoullis equation" or search "pump curves" on the net.

anyway... hope that helps

I agree. Most current laptops start to overheat after you had them a year or two and they get all clogged up with dust. It's a major problem (particularly as many laptop designs make it very hard to clean the heatsinks).

This design is not only more prone to dust (with it's small holes) but I wouldn't be surprised if the "wrong" dust caused arcing and took out your whole machine.

Interesting idea, but from the graph that's posted, the performance benefits of this solid state fan are at the high velocity end of the scale. Generally, I find it preferable to keep fan velocity down to stop my computer from sounding like a Hoover.

The acoustics of this should be interesting. At similar air velocity it will probably be quieter than a comparable mechanical fan, but you're still going to get noise from the flow of the air through the heatsink.

Airflow in itself doesn't make noise; turbulent airflow does. The blades of a normal fan create many turbulent vortexes, causing noise.

In theory, this solid-state fan could be considerably quieter than a conventional one. In practice, though, I have no idea of its actual noise level.

Turbulent flow is a critical requirement for efficient heat transfer. It is, in part, why a high flowrate is desirable. Turbulent flow is achieved sooner, all things being equal, with a higher flowrate. At this point, I'd assume the reduction in noise of this design would come from better directionality of the flow, elimination of the mechanical components but not from the reduction of turbulence which would be counter to effecting better heat transfer.

A good point, but I'm sure they can create turbulent flow if it's desired, simply by the geometry of the device itself.

I don't dispute the need for cooling and especially cooling in confined spaces.

However, overheating laptops tend to be caused by poorly designed cooling setups, clogged (with dust) vents or some sort of user silliness (like blocking the exhaust). This smaller fan isn't going to help with any of that.

In my laptop, even when the fan is quiet, I can easily detect a jet of warm to hot air coming out. Can we really do with a current equivalent to a fan 35 times the size (I'll assume area)?

In short, the only real issue it solves is fan blade noise. Which is fine and all but hardly a revolution. It also doesn't help that similar concepts have popped up every once in a while without any results. Unless I'm totally misunderstanding this, it's same old "ionic wind" type of tech. Mmmm, I love ozone.

The article doesn't say anything about the fan being quiet. Could be twice as noisy -- just isn't coming from a blade. Moving/accelerating air has the potential to make noise (or at least sound, "noise" is just an interpretation of sound).

I'm building from the another post' claim that it'll be quieter (my original post stated it'd be loud).

If this thing is quieter, then it's worse than useless; it'll spit out ozone and ions as well.

Huh, I'm surprised this statement is simply modded down despite not being particularly incorrect (if at all).
