Quick idea// compressed air and venturi effect

post #1 of 7
Thread Starter 
Quick idea

1. As we know compressed air passing through a small point becomes really cold

2. Water conducts heat well

So why not making something that takes advantage of these simple facts?
The Idea:


A compressor or Gas cylinder filled with compressed air is released into a pipe


So as the air passes through the venture chamber it gathers droplets of water
(WOOO MS paint biggrin.gif see attached 1 venturi)
(http://en.wikipedia.org/wiki/Venturi_effect check it biggrin.gif)


The air/water is then pushed through the 4 jets into the cooling block (One each corner all angled to the center of the die) (This could be made either in a block or direct die)
(WOOO MS paint biggrin.gif see attached 2 block)



The expanded air and water is then removed by the extractor that is in the center of the block (not too sure how to make the extractor)


You could then pass the air/water through a pipe into a res with pressure release valves at the top to release the air, trapping the water in the res.


The amount of air/water provided can be controlled by the variable release valve on your compressed air storage device (compressor or gas bottle) or maybe by a choke (think of the inner working of a carbie)


Sorry I could not provide proper diagrams or a better though out plan (I am stuck in a lecture and tring to take notes at the same time so it is very rushed)


This was just a random idea I got while bored at uni and I doubt I will have time to try it since I want to spend the small amount of time and money I have on a volenti cooler but I would love to see something like this made.


Let me know what you think biggrin.gif

I think this would be very inefficient compared to a phase change system.

Hmm yeah but so so much cheaper and you need little skill to build this in comparison

The biggest draw back is the fact that you have to run a compressor to compress the air, this would put it's power usage right up there with phase change units, it is much easier to construct yes but not feesible,

If you could solve two major problems I would be all over it;

1) NOISE
2) POWER USAGE (inferior cooling with equivalent power usage to phase change)

It will sound like non stop air brakes at the local truck stop anywhere near your pc and the noise will rally your neighbors to hunt you down like a dog.

It's not impossible, I just don't see the advantage unless you at least overcome the noise factor of the compressor. teaching.gif

I have a Makita Mac700 air compressor I use for finish carpentry. I also have a bigger 8 gallon. Both are so loud you can't talk to anyone near it when it goes off without shouting, and both are considered "quiet" as far as compressors go. It also has a penchant for blowing 10A breakers. Both of these things equate to a less practical solution than phase change or water cooling.

Yes it is possible, and would probably yield better results than most conventional cooling methods (air and water). But it's just not practical.

Also, it would have to be a BIG compressor with a BIG motor to maintain a constant stream of compressed air, which would be quite expensive. And loud. And require a lot of power.

Think of the size of the 4 jets, the required compressor or cylinder would too not be large, and as well as that the compressor does not have to be anywhere near your pc. Yes power usage would not be the best but i truly debate that it would be to the same level as phase change.

oh well its a shame nobody will ever try it to find out

There are devices that are designed to cool via similar effects, but they need vast quantities (~8 cfm to cool your CPU) of air. See this thread for details.

They really can only be used by places with industrial compressed air supplies (typically a screw compressor or a gang of piston type), even then you typically use other methods of cooling except in a few limited cases where you need explosion proof chilling or other odd-ball requirements.
