The post that I did almost a year ago about my Homemade Ranque-Hilsch Vortex Cooling Tube (or just Hilsch Vortex tube) seems to have generated a lot of interest. Someone has asked me to put up more details about how I built mine and I decided that would be a good idea. Besides I was looking for something to build today so I built up another one! HERE is the original post that I did last year if you want to see what I am talking about and below is a picture of that first one that I built.
If you are interested in the dimensions and details of what I built check out the first post at the above link or HERE again for your convenience. I figured that since that post has been up for almost a year and it is one of the most often viewed in my blog I can't really add to it so I decided to make a video explaining how I made my cooling tube. Without wasting more time below are links to the videos - enjoy!
Part 1 of building a homemade vortex cooling tube:
Part 2 of building a homemade vortex cooling tube:
Check out my post HERE from last year for more details of this tube!
UPDATE: Be sure to have a look HERE at this post and video for simpler construction of a more successful Vortex Cooling Tube that I built.

otto, my brother, you are a saint. i appreciate you actually taking the time in making this video which is very clear and understandable. you are definitely on my nice list. the narute of my job, a jet fighter fuel cell technician/mechanic. i work inside these cells the sizes between a refrigerator box (biggest) down to about 4 feet cube. you could understand my dilema why i have to have these. thanks to unselfish people like you my job is now half hard/easy when it used to be just hell especially during the summertime. i stay in these cells a whole workday at times. thanks brother. i wish you success in anything you do. peace!
ReplyDeletekokok sparky,
ReplyDeleteNo problem check out the comments on the other blog post about this!

Can you tell us how it worked out? I mean what the temp differences were?
ReplyDeleteGreat project. Was thinking of doing something similar.
I hadn't thought about PVC though
Thanks
Books,
ReplyDeleteThanks for checking out me blog! I got about a 15 degree temperature difference from this tube. I built a couple of others and one of them worked much better with a 50 deg C difference at 550kPa pressure (80psi 122F). I'll write up a post and video about that one soon. Check out the "Site Index of Projects" link at the top of this blog and scroll down to the Vortex Tube links for more info about these.

ReplyDeleteThanks for the info, sure I will check out Site Index of Projects. I was going to ask you what did u do different with the one you had better results from? I ll be looking forward to your updates and videos
Books,
ReplyDeleteThe tube that got better results is the smallest one that I have made thus far with an ID of about 0.3" and it has only 2 inlet jets that are angles slightly toward the hot end. As I mentioned I'll make a post about it and a video soon with lots more details.
Otto
Books,
ReplyDeleteThought I'd let you know I posted a video and blog post of the third vortex tube with details and pictures. I hope it's all clear and easy to understand. Let me know if you have any questions and if you decide to make one be safe and take care with compressed air!!! Check out the blog home page and of course the Site Index of Projects Link for info...
Have fun!
Otto
hii...my name is Tarek...am a mechanical engineer student and i'am so intersted for making this project...so can u plz send me the perfect dimensions!!!
ReplyDeleteTarek,
ReplyDeleteThanks for checking out my blog! Have a look at my other post:
http://ottobelden.blogspot.com/2010/12/another-home-made-ranque-hilsch-vortex.html
and the video. That tube worked the best for me. Be careful with compressed air and always wear safety gear.
If you have any questions please let me know!
hii..i just wana tell you that i made that project and i took the 1st place in an event our university made for mechanical department...so congratss:D...can u help me in one more thing: What are the Marketing and Buisness elements for that project?
ReplyDeleteBob,
ReplyDeleteCongratulations on the 1st place ranking!! That is great news and I'm happy that you found the information in my blog useful. Vortex tubes have a lot of industrial uses and there is a market for them. They are used for 'spot cooling' in welding applications, cooling work pieces and cutting tools in machine tools and for cooling electrical components in hot environments. The advantages of vortex tubes are they require almost no maintenance and all you need is a lot of compressed air to make them run. A quick internet search will give you more information but feel free to ask me if you need any more information.
Thanks again for checking out my blog and taking first place in your studies.

Hi Otto. This is a very interesting blog. Please advice if this can work for my requirement. I live in near desert kind of place. At my house I have overhead plastic water tank that stores 1000 liter of water. Even early morning the temp in the overhead tank rises to 60 degree C or 140F. It is so hot I cannot take bath with this hot water. Would it make sense if I make a Long coiled Copper tube imerse it in the overhead tank and attached it to the cold side of the Vortex tube. Then I run this system automatically early mornings when I am home and in late evening when i return so as to get normal water in my taps? Any advice will be useful. Thanks.

Anjeel Babbar,
DeleteSounds like you like in a very hot place! A vortex tube is good for cooling very small areas when you have a lot of compressed air available, like welders and in machine shops. For cooling that amount of water you would need a lot of air at a high pressure and even then it probably wouldn't be the right way to go. Vortex tubes are not very energy efficient.
I think you might be better off covering the water tank with solar insulation and if it's still too hot try pumping the water underground before it comes out of the shower.
An alternative is to have an underground tank of water that you can freeze at night with a cooler and run the water from the roof tank through a radiator that is in the underground tank.
I hope that helps!
Otto
