Alright, I know I've been posting a lot of links recently, but I think this one is most worthy of attention:

http://mechdb.com/index.php/Spinner_Cooler

It's a really neat intercooler design which cools by rotating the cooling passages in the air. Plus the guy developing it is pretty cool, I just got off the phone and he's trying to finish up the seals part of development, and then he can start putting it out on the market. He already tested it a few times, there are videos of it running on youtube.

holy parasitic drag batman. So.... instead of using a FMIC, this guy thought it would be better to create something that would create a big restriction in your intake pipes and use some of the energy the turbocharger uses to compress air to spool up this intercooler. You could get the same effect by putting a cooling fan on your intercooler. It's not like it's free energy, the turbocharger has to push that air through, the more things there are in the way using that air pressure, the harder the turbo has to work. I would really like to see what he is backing his efficiency figures with.

I think given a side by side comparison, there would be a negligible difference between that and a standard intercooler. If not, the spinning intercooler would cause a loss in horsepower and an increase of intake temperatures.

I wonder how long the seals and bearings will last on something like that.

I guess the only way for that guy to truly test it would be to rig it up and do a dyno test. You have to consider that regular FMIC are not that great as far as being restriction free either:



I wouldn't say that's any worse than the restriction in his design. The only thing to worry about is the spinning action, one thing to remember is the spinning action decreases the need for having all the volume which the compressor has to fill before reaching the combustion chamber, creating turbo lag. Another thing to consider is FMIC restrict the cooling system radiator behind it creating more inefficiencies in the cooling system. I should get him to join here too, it would be an interesting discussion.

I just think there's gotta be some merit to it otherwise he wouldn't have continued to try the idea after making a prototype and trying it out. While I do think it needs some more testing, I think the biggest thing he's trying to overcome right now is the bearings and seals issue, he says he's having to go with some aircraft grade materials to finish it up. Once that's accomplished we'll know for sure what it is and isn't capable of.

Oh btw, have you guys seen the two videos?

They are pretty neat:

the restriction I am speaking of is the energy needed to spin the intercooler. Once you factor in drag from wind resistance, bearing resitance, seal resistance, along with the restriction that comes naturally from trying to push the air through any type of heat exchanger, you will find there is a LOT of restriction.

Furthermore, the cooling efficiency he is alluding to comes from the fact that the IC is spinning and therefore drawing air over it. This is accomplished by a normal IC from the air or water movement over the heat exchanger while the vehicle is in motion.

It is a fun little concept, however, it appears to me that it will be less efficient than current methods. I would venture a guess that the reason he continues to work on it is because, 1: he probably failed to see the big picture, 2: he hasnt considered the possible shortfalls of his design, 3: he wants to introduce his new design and hopes people will buy it cause it is something new that is making big promises, or 4: he is just having fun experimenting.

besides, this is by no means a new concept. I have seen it before.

I dont remember where I have seen them before. That kinda thing pops up every couple years.

On the same note, you can also find people who build turbines that are air driven for intake tubes. you know, basically to work like an intake tornado, but to provide an actual swirl to the intake charge. Same flaw with that design. While they work much better than a Tornado at providing a swirled intake charge to reduce turbulence and increase charge velocity, the same problem I imagine that spinning intercooler will have arises. Low service life, and parasitic drag.

There is unfortunately no such thing as free energy.... I mean the concept is fun to play around with, but there are so many drawbacks.

Even if he did have something working, he has to fully enclose it with some type of screen to keep debris and fingers out, and in the end it will take up just as much room as an equally efficient IC, so I just dont see the worth in it.

Well I'd be interested in seeing who else made a similar device, because I haven't had much luck with finding other designs. Finding them would be nice, so that the reason for their failure can be revealed.

I'll see if I can find anything. Like I said, I have seen stuff like this pop up every few years. I will get back to you when I can find anything on it. However I am fairly certain that what I have already said about it will hold true.

IMO the only benifit there would be to a spinning IC would be the cool factor, as in, hey look under my hood, a spinning death wheel. It slices, it dices, it can process a cow and spit out cooked hamburgers on your drive to work. :D

Haha you got me sold! Where do I sign up?

I wonder if that's what spinners were intentionally designed to do, you have to admit they do function kind of similar to a meat grinder :lol except in an inverted design. The first part stays stationary so would you feed the meat from the inside of the wheel and have it come out the outside? Or?

ARRR thread jacked. Spinner were orignally designed in cali so that they could do their rolling stops easier. That way when the cop pulled them over for not coming to a complete stop they could just say. Did you go by my wheel movenment? How could you tell that i came to a complete stop? :lol:

Sorry couldn't resist. Great wow facter but the maintence is just so damn demanding.

You could technically design a spinning rim to cool rotors if you were to put a turbine like fin assembly on it. Or you could design one to have a perfectly flat cover for aerodynamics, without increasing weight on the wheel since you wouldn't have to rotate the mass with it, although the friction from the bearings might waste some energy.

Or you could design the wheel itself to be almost like a turbine wheel without any spinning or moving parts, kind of like the following image but even more aggressive and slimmer fins.
