Anyone know about Venturi Tubes, or Vortex tubes

[SilthDraeth]

I am curious about the application of a venturi type tube, also known as vortex, and hilsch tubes, and many other names.

Basicaly, from the way I see it, they use a device like an air compressor to feed the air into a T shaped tube, with the air coming in on the vertical, and exiting on the horizontal. Somehow they get hot air out of one side, and cold air out of the other side.

I am curious if anyone has used this in case cooling, if they know about the physics of it, would it be possible to make a venturi tube like contraption thats blowing the hot air out of the case, and the cold into the case, and have this all be fed by a 120 mm case fan.

Please reply to this if you can help me, or know a site that has do it yourself plans. Thanks.

Venturi tubes are for liquids, rather than air. What you're looking for is information on a Ranque-Hilsch tube.

Thankyou. It would appear that you would need some sort of mini air compressor, or blower, feeding two intakes, in order for it to work. /sigh, Well when i get a little time to experiment I will see what I can come up with.

Thankyou for the link though, that link is a lot clearer than the links I managed to dig up on my own.

Any time you create a pressure drop or expand gas it has a cooling effect.

I've been thinking about the same thing. We use both of these principles to recover propane from fuel gas by cooling it to about (-90) degrees F. In order to get a desired effect though I think it would be extremely loud.
