Noobtastic14's liquid cooled Neo 18s hardwood wall.

Liquid Cooling system update for the build log:

With the Floor removed, the water system sits in front of the spare tire and under the back of the subwoofer box.

The tube on the left is hot water entering from the woofers, to the right is the water being pumped out and down to the radiator.

The hose in front shows me how low the water level is

View of the radiator, radiator fan, and feed tube from the pump above.

The radiator sits at an angle and does not sit below the exhuast/body but it does sit just below the plastic

The radiator is sold as a dirtbike radiator, so it comes with a protective grill. Its also inside of the rear tire and out of the direct dirt/water/rock spray.

The woofers are wrapped in 7ft of copper piping and coated in Heat conductive silicone. To keep its shape and contact with the motor, its wrapped in stretchy rubber tape and a few plastic zip ties.

I measure the motors with the shown traditional thermometers and use the IR thermometer for measuring temp within the gap.

Thanks for looking-

Just sick man. That all I can say.

So field testing the wall has had a nice positive result.

The show on Saturday was pretty brutal for heat and it was affecting all the equipment as well as the people. I did some demoing and then measured

Ambient outside temp: 97*F

Ambient box temp: 110*F

Woofer Motor inside the pole: 125*F

Woofer motor outside the pole: 115*F

Copper tube (water temp): 100*F

I took a break and sat in the AC and played two games of boom beach (5-7min) and then rechecked the temps

Ambient outside temp: 97*F

Ambient box temp: 110*F

Woofer Motor inside the pole: 115*F

Woofer motor outside the pole: 105*F

Copper tube (water temp): 100*F

Ideally 110 degrees is where I'm comfortable playing them at demo outputs and the cooling setup shows that on a very hot day the water will bring the woofers back to safe levels just minutes after I finish demoing. The initial positive results are giving me more motivation to address the heat issue on the amps. I'm currently wired very low and create an awful lot of heat back there.

Thanks for looking.

*BTW with all the hot gear she did 153.4

I ended up with some serious voltage drop towards the end of the show last weekend.

At the time I attributed it to a hot stretchy belt combined with an alt that was running 30 degrees higher than average.

Turns out-

My quarter inch angle iron bracket broke!!

I'm looking into places to get it welded back up and maybe a bit of an extra support welded in or something.

Phew! Luckily the car was only down for a few days.

I had a local shop weld together the bracket as well as welding in a support to reinforce the joint in the future.

Also, I lowered the belt tension a bit. I had a bit of belt squeal and tightened BOTH belts when really it was only the small alt belt that needed adjusting. The result was an excessive pressure on the bracket that caused the crack (or so I'm assuming.)

Either way- its back up and running!

I think August 15 is the next show...

tuned in for more testing and results!! how is that water cooling working while driving? i bet its pretty sick

[Noobtastic14]

Thanks!

Yes this is exactly how the cooling system on your car works, its just a much smaller scale.

[Noobtastic14]

Today's number's-

Started at 113*F

10 minute drive to Chipotle at about 80% output

103*F on arrival

105*F when we left

and (after another 10 minute drive at ~80% output)

97* when we got back to the house.

With nothing but heat from the sun and heat from the amps the subwoofers dropped 16 degrees with liquid cooling.

awesome!! does it help much when you are at shows? I think I saw you post on it earlier? obviously while driving its going to work great.
