New Barrel Cooler

[MrBottleneck]

My son and I always get tired of waits for barrel cooling. We had talked about how we could make one while shooting yesterday. My son came home from work and said he had a plan to make a barrel cooler. He had a lil trouble in the design aspect so, I got involved and the finished product is done (except we are looking for a nice 12v power supply. Testing was done from a plug in power supply.
The white piece is a perfect fit into the action and the case primer area has been drilled out for good air flow. Its just like fitting a bore cleaning guide.
The body is actually two hard funnels bonded together (most the work) to form the shape you see. It took some creativity but, it ended out working. The fan is a old 12v PC fan. Total cost to make like $2.
We could have bought a smaller BarrelCool but, whats the fun in that we figured.
So now we have the BottleneckCooler. LoL

You could use two 6V lantern batteries wired in series to produce 12V DC.

Nice work. Might look at the 12v deer feeder batteries available at most big box stores. Lots of kayakers use 'em to power fish/depth finders. Will fit inside a 6 pack soft sided cooler, I've got one inside a plastic water tight container I got at wally world.

Neat home brew idea you guys came up with.

I use those compressed air cans you get for blowing off your keyboard and other electronics. Get them at the dollar store cheap. Toss a couple in my range bag on hot days and it cuts the cooling time down enough to suit my impatient nature.

Great idea...and I'm sure you guys had fun putting that all together!
If those were marketed I'd bet ya could sell a ton of em.....LOL.

Designing these coolers can be fun, and beneficial to your hobby. That's why I developed Chamber Chiller, pictured below:

Your schematic is incorrect.
Your drawing shows 2 shorted batteries. Minimally it would rapidly drain both batteries. With no load/ shorted, there is the possibly of bursting them or causing a fire...
This is 2 6v batteries in series to produce 12vdc:

LOL, We would sell zero because its the most craziest looking and overly big barrel cooler made. But, it works and it was fun goofing around making it like you stated.
Thanks for the comments guys.

I print the nozzles on a highly-optimized $300 XYZ DaVinci Jr, with a design that I tweaked to work around it's shortcomings. I've also printed them on a much more expensive $1300 MakerGear M2, which turns out very nice nozzles that are just slightly better in quality.

You may have reached the limit of how much air will flow through an X mm tube under a given pressure. A smaller fan might work just as well.
