Really Effective Barrel Cooling Fan

I REALLY wish they had used a much quieter fan and motor. As I now REALLY hate having a RifleKühl on my squad, or the squads next to me at matches.

Or at least, I wish they’d included a thermocouple and an interrupter control or bimetallic switch such they wouldn’t run continuously.

Shooting at home, I don’t mind the noise, but electronic muffs pounding that roaring cicada sound into your head for 6 hours a day every weekend is not my favorite experience.

Never seen one, but will have to check it out. When it is 100 degrees here in summer it is almost impossible to truly cool off a barrel. I've resorted to leaving my truck running with the AC on high and placing them in the cab for a few minutes.

I've had an idea of getting a copper coil made for distilling and getting a bucket that it will fit into and fill and freeze water around the coil, then one can hook a fan to one end of the copper coil that exits the bucket and have a flexible silicone tube attached to the other end that will enter the barrel's chamber. If there is enough length of copper coil I wonder how much the air running through copper coil would be cooled when it enters the barrel. Seems like for matches it would be a sweet setup.

We get hot here in the high desert in the summer 105+ on occasion so heat is a big enemy.

For PRS matches, we off-stage the rifles adjacent to the firing line, then stand back a dozen feet behind the shooting positions to spot. Closer than I want to be to these things, as loud as they are over amplified electronic muffs.

It’s not as annoying as having a guy on your squad who hangs a Bluetooth speaker on his spotting pod and blares music the entire match, but I’m not a huge fan of barrel blowers at PRS matches.

The most effective and efficient barrel cooler I've ever used is the Winter Breeze system. Especially in a busy prairie dog town when I'm ripping of a shot every few seconds with a high velocity varmint rifle and the barrel gets sizzling hot quickly. A quick blast of ultra-cold CO2 down the barrel cools it right now and I'm back to shooting. The small tank lasts about a day of heavy shooting and the larger tank is good for a 3-4 day shoot..

And here I wondered if anyone else did that. LOL But hey, it works!

That’s how I disposed of a co2 fire extinguisher that they didn’t want to pay to refill at work. Dove field was wild, so bang bang bang bang bang bang pooooooooooof bang bang bang bang

Now that’s the way to do it.

This one has been around for a while. Similar to the OPs. Not sure how loud it is

I went a different route and got a cheap air mattress inflater that has a USB chargeable battery. It works pretty well.

Low tech. Ice water and sponge. Cool from the outside. Get fron cooler that contains your soda & water to drink. Dont let water drip into the barrel chaannel.

I have one that takes 8 d cell batteries. It works fairly well. It's loud though.
Most of my shooting is off the back porch now, so it's easier to just step inside and play with the kids for a few minutes.

I wouldn't use it on a gas gun, but a BoreSnake soaked in ice water works pretty well.

Mine is a Coleman inflator with four D batteries. I've used it for a year and it still has juice.
I have a rubber hose that fits into the chamber so it can sit next to the rifle.

It works well, I agree with @Varminterror though, it is the most annoying sound to hear. Through muffs, around the corner, or just sitting there waiting for it, it is definitely too loud.
I find I the range because I want to hear guns, not vacuum cleaners!

I have several battery and car adapter powered inflators, I do a lot of floating down the river with the kids.

I will buy two more this year looking for the perfect one. Another inflator that I hope is quiet, and the Riflecool fan, because it is one fifth the size. I may just have to deal with the noise.

I have one that is quiet but doesn't work well, two that are too loud, and one that works awesome but sounds like a turbine powered Shop-vac.
(How hard is it to assemble them tight enough to not rattle?)

Try a small Pelican Case, or cheaper alternative, with the foam insert as a "silencer" of sorts for your noisy barrel cooler fan.

Carve out the foam insert to fit the barrel cooler inside such that the stem sticks out one side. Then carve a zigzagging suction channel through the foam to a hole in the other side of the case for the air intake.

The foam and case ought to make an excellent sound dampener.

@RetiredUSNChief - most of these little fan motors will get quite hot during extended use if you were to wrap them in insulating foam. Then we’d get to find out either whether the designers used appropriate protections, or what the unit smells like when it starts to melt.

Unfortunately true. Even a hand towel for a draped on muffler will get things to hot...

I have had more of them than I thought.

I have a spigot just around the corner to the bench. Maybe a copper tube run gently down the barrel and attached to the garden hose would make a good barrel-cooling lawn-waterer.

A condensation covered pipe in the bore...
Hmm, maybe not...

@Demi-human - I’ve known a couple guys who would recirculate water from an iced cooler with a 12v pump THROUGH the bore when Varmint hunting. Dry patch, oil patch, back to rocking and rolling! Can’t say it’s on my punch list, but I know it worked for them.
