newls1 Posted June 19, 2009 Author Report Share Posted June 19, 2009 If you are going to water cool, you need to water cool the internals, not the case. The internal heat transfers to the outter casing through convection. I'll be cooling the outer case. I'm not going to say this is going to keep the amp ice cold to the touch, but every little bit might help. Shit, it was 96degrees here today in the ATL area, just listening to the radio at near regular volume, makes my MD3D slightly warm to the touch. So with cooling the outside shell of the amp, it will at least stay as close to ambient temp as possible, which in turn should keep the internal parts that touch the outter shell, cooler as well.

Armoredhaulin Posted June 19, 2009 Report Share Posted June 19, 2009 If i remember right the Bazooka amps were cooled by anti-freeze...not just water and they were designed to cool the boards not the cases. The PPI's were on the same idea but before my time so I am not to par with the ins & outs of them. Quote "I don't bullshit.

Stephen Posted June 19, 2009 Report Share Posted June 19, 2009 we have a watercooled bazooka amp in my electronics class that we fixed. Quote you can cook bacon shirtless if you're not a pussy...lol not hatin, but am i wrong here it looks as if the amp is not grounded its hooked directly to the battery. it that the way it should be.

kingsuv Posted June 19, 2009 Report Share Posted June 19, 2009 You can also look into Thermoelectric plates. The exchange at the amps is pretty straight forward. Cooling the fluid to a useful temp will be the bulk of the design. Good luck with the build. Quote Designing, building, and shipping boxes. Yahoo IM - kingsuv00If the listening level is too loud, please inform the driver, so he can promptly pull over, and let you out. not many cars can get me to pluggin my ears but this one.......damn. I mean the first minute is ok but that thing just really starts digging deeper and deeper in your earhole till you cant stand it no more. Seems like it does it with relative ease....16 12's on 8 amps.........gotta love it. Link to comment Share on other sites More sharing options...
Boon Posted June 19, 2009 Report Share Posted June 19, 2009 (edited) Peltiers for the win, it's not like you have a shortage of high-current 12vdc on hand Watercooling the outside of amps is inefficient. And you have the wrong term above, head is CONDUCTED not CONVECTED from the inside of the amp. To put it in PC terms, what you're proposing is kinda like having a huge aluminium heatsink sitting on your CPU and then attaching a waterblock to the side of it. It's inefficient because your heat goes silicon -> heatspreader -> heatsink -> waterblock -> water -> radiator -> air Currently it just goes silicon -> heatspreader -> heatsink -> air I'm not saying it won't be cooler but the huge number of relatively poor thermal junctions will make it suck. You would be better off machining channels in the heatsink and using that as the waterblock. Even better, you could do away with the heatsink and machine your own custom copper waterblocks that you screw the transistors directly to. THAT would be properly badass. While you're at it you could even lap the transistors for better cooling Also I don't think having rads in the glove box would work - you're talking 2 very very long runs of tubing (flow fail) and a pretty crappy place for the rad. I'd put it in front of the port for added cooling :hairtrick: Edited June 19, 2009 by Boon Quote 10.x volts fo' life! Link to comment Share on other sites More sharing options...

I know the tubing run was VERY long, The D5 can typically compensate for about 11-13 feet due to its head pressure. I am going to draw this all out here and when done, i'll post it up.

finkster Posted June 19, 2009 Report Share Posted June 19, 2009 (edited) Ive asked this question before. i think someone said that amps work best around room temp, im not sure on that though.
