We can talk about this idea as there is already a patent in place for this , and I have read that some testing has already been done on a diesel engine. Also, I've read that the OEM's are testing with this idea for intercooling as well as heating and cooling the cabin of the cars.
Vortex Tube. You hook an air line to it and it divides the air up into a hot stream and a cold stream.
Ever since I read about the principles involved I wanted to build a vortex tube so over the last couple days I did. Tested it and made a vid. From my experience with it I am pretty confident that a twin turbocharged vortex tube intercooler could be built that would be light and make a very dense cold intake charge.
I am blowing off boost right now to help control my max boost pressure, my thoughts are why not cram the boost to this tube, blow off the excess & the heat and keep the cold amount that I want.
Heres a link showing an animation of whats going on in a vortex tube.
It uses centifugal force of the vortex formed to divide the hot from the cold. The hot is on the outside of the tube while the cold returns up the center of the vortex. They say that the vortex will rotate at 1,000,000 RPMs.
You can research "Vortex Tube" on the net, there is alot of info and some good reading.
Heres my vid of the results of my experiment with building a vortex tube.
Notice that no matter how I adjusted it that the outlet temps remained relitively cold in the 20's, but when I open the hot up a little the cold side would drop like crazy, although it was still flowing most of the air. Coldest I've reached so far is 5* and the hottest out so far is 165*.
Heres the idea I have in my head about using it for an intercooler and boost controller. Lets hear what you guys think. I'm open for criticism, and I fully expect to here plenty from the naysayers.
I completely understand that the diameters of the pipes, lengths, nozzle diameters, and all of that would have to be experimented with to reach maximum efficiency. I believe that with the larger tube and the larger volume of the turbos, that the cetrifugal forces at work might actually work better and not actually require as much pressure.
