Ionic Wind Heat Sink

Just when I thought I didn’t have another ionic wind cooling project left in me I was more or less overwhelmed with emails from our last version that really let me know there is strong interest in this type of system cooling. So I decided to put one more idea together that would provide far better performance than the 2.0 project and still fall well enough in affordable bracket that it’s still practical for everyday use. After tinkering around one afternoon I came up with the concept for this little project. I have personally been using this in a specialized system I have for over 2 months now and haven’t had a single problem with it. The other added bonus with this system is its really easy to clean the grounding plates as opposed to other versions we had put together.


We picked up the acrylic that we used in this project from our local plastics dealer. We double checked and found several vendors that offer precut materials cost effectively on eBay. The cut list is really simple.

1 – 4″ long 3 1/2 Inner diameter pipe (4.00USD)

5 – 4″ X 4″ 1/4th inch thick acrylic (6.00USD)

Copper Pipe:

We picked up a 1 ft length of copper pipe at our local home improvement store. We used a 3/4″ Dia pipe for this project. 1 inch would work equally well but we didn’t notice any performance difference at all between them. We cut our pipe into 6 – 2″ lengths (1.00USD)

High Performance Heat sink:

We used for this project a arctic cooling freezer 7 heat sink. This has been a good steady mid line heat sink for us for a while now. Its copper core and heat pipes give it the edge we have come to expect from this type of cooler. (20.00USD)


We used about 3 feet of 14Ga stranded copper wire for this project. Using separate colors of wire while nice is not necessary… unless you braid them. Then you have to use more than one color… (1.00USD)

The Corona emitters:

Also known as tacks, pins, or real small nails. These are very small tacks that are about 5/8ths of an inch long. It’s important that the tips come to a sharp point so sanding them with sand paper to make sure there even and sharp will help with the effectiveness of this and drastically cut down on ozone emission. (1.00USD)

The Power Source:

We picked up this high power ion generator from for about 24.00. This is a far cry better cost than the disassembly of an ionic air cleaner for the components. This unit is a 12V native unit so we can run it off the internal power supply without any major issues. This unit puts out several thousands of volts. it can hurt or even kill you. Do not do this project unless you have a firm grasp of electronics.

Step one in our project is to mark up some of the acrylic sheet that we picked up. To do this we simply took the tube and scribed with a marker the inside of the tube. if you get marker on the acrylic sheet or tube its easily removed with a little rubbing alcohol.

Using a band or scroll saw cut around the outside of the black line you scribed. If you use a good course blade at a high speed it tends to not melt the acrylic and create a mess. If the cuts get a little uneven it’s ok. They don’t have to be perfect.

I am in many respects the text book example of someone who shouldn’t be successful. I was an outcast in my grade school years, and a poor performer in school, unable to fit the standard mold. Fortunately I found small opportunities that I took advantage of, and coupled with hard work they have guided me to where I am today. I spend my time running several businesses I own, developing new products and sharing what I have accomplished with those that deserve opportunities that they wouldn't get any other way. InventGeek has been a step on a path that has helped bring me success and confidence by the simple act of doing. I encourage our readers to do what they can to better themselves a little each day, because overtime it's amazing what you can do!
