Cold Air intake

Cold Air intake

Cold Air intake

(OP)
This question is a bit vauge and is prompted by something which I read in a book by an automotive expert (Smokey Yunick "Best Damm Garage in town") In the book he describes an air intake which is divided into a Y with two unequal lengths. He says that the temperature or the air exiting the two outputs of the Y can be different and the sum of each divided by two is equal to the inlet temperature. He references a designer called Hayley who develped this system for cooling coal mines. Does anyone know the theory behind this or where I could look up some information.

Thanks
Tom

RE: Cold Air intake

hmmm sounds like a corallary of the Vortex Tube.

I cant tell you why, just that it sounds possible

RE: Cold Air intake

Sounds like hocus pokus to me, my comment being based on the laws of conservation of energy.

RE: Cold Air intake

Greetings,
I think NickE has the theoretical answer.  Do a google search for Vortec Coolers or electronic cabinet coolers.  Compressed air (like perhaps an airstream) is forced thru a venturi.  Some air is diverted and MAGICALLY is hotter than hell while ice cold air is blown into the cabinet.  We use hundreds of these but it's been twenty years since I read the explanation.  Conservation of energy still applies as the pressurised air is part of the equation.  With DP being a critical function I'd wager Pat's response summarises what we'd get in an automobile...Don't forget that Smokey was brilliant but not all of his ideas were practical.  even fewer were allowed ))

Hi Steve, Nick,

Thanks for the response. It looks like this is what I have been looking for. Nick, What have you been using the coolers for. I have posted this question on a many forums and this is the only one which I got an answer.

Thanks
Tom

RE: Cold Air intake

Ummmm... I just remember reading a Pop.Sci. when I was a kid and reading about vortex tubes, They are all over the web now cause they are relatively useful as GT6Steve says. I think that they work by transfering the heat energy from one stream (that is spinning rapidly) and another that is not.
