Minimalistic multichip DIY LED build

[karimwassef]

As far as posting my cooling LED build - I have so many other DIY projects juggling in the air right now. I'll post the pics but I won't have the bandwidth to start the new thread for a bit.

here's the air-cooled baseline

here is the 6 high density fan or a triple heat exchanger

and here is the dual fan copper/aluminum plate with embedded Peltier chillers

I'll show the internal constructions here - I think they're self explanatory, but the thread will describe more

<a href="http://s1062.photobucket.com/user/karimwassef/media/A49C27C0-44D1-4B4C-9261-9DC6EC7E287E_zpssrrnhpo9.jpg.html" target="_blank"><img src="http://i1062.photobucket.com/albums/t496/karimwassef/A49C27C0-44D1-4B4C-9261-9DC6EC7E287E_zpssrrnhpo9.jpg" border="0" alt=" photo A49C27C0-44D1-4B4C-9261-9DC6EC7E287E_zpssrrnhpo9.jpg"/></a>

and here is the closeup final view of the Peltiers.



By the way - I'm not convinced that Peltier is the way to go. I am biased towards the traditional 6 high pressure fan heat exchanger.

And here is the Aluminum frame that the LED chips will bolt on to

<a href="http://s1062.photobucket.com/user/karimwassef/media/91CAD15A-3728-4540-9895-29ACBFDB5CCF_zpseps8f5mu.jpg.html" target="_blank"><img src="http://i1062.photobucket.com/albums/t496/karimwassef/91CAD15A-3728-4540-9895-29ACBFDB5CCF_zpseps8f5mu.jpg" border="0" alt=" photo 91CAD15A-3728-4540-9895-29ACBFDB5CCF_zpseps8f5mu.jpg"/></a>

This has water pumped in at one end and out the other end (internal tube carries water to the other end).

Here is the molding of the epoxy end to for a watertight seal

and this is my conceptual design including 2 of these 8ft liquid cooled LED Aluminum pipes @ ~1200W each (12 LEDs/Aluminum pipe x 100W each)

That build is Great!!! Thank you

I was thinking about a water cooled pipe for a large freshwater build I have been considering. I was planning on using tubing from 80/20 inc. for my base and pumping water through it. I wanted to go with water cooling for a large Amazonian planted tank so I had the option of dumping the heat into the tank in the winter with a heat exchanger in the sump vs dumping the heat outside or into the room depending on whether I need the heat or not. I like the 80/20 aluminum because it would allow me to use different profiles and i think it will be more rigid. i would really like to follow your build to see how it goes.

 

[karimwassef]

I never considered pumping tank water into the Al square channel. I run marine, so that would be clearly problematic.

Even with a freshwater tank though, I would rather run pure DI water and then run a heat exchange loop into the tank water to heat it up vs. running straight tank water.

I just believe in separating critical loops and then using a control mechanism between the two.

Also - pure DI water is the best thermal conductor. Impurities of any kind will degrade performance. The main reason we don't use it in cars is because it freezes - hence antifreeze.

page one of this presentation from DOW says it all

The rest is pretty good too by the way

karimwassef,

I was out on the road so I could respond like I wanted to. Thank you for putting up with my repeated pressing at a couple of points to conclusion. Now I understand.

Once again "¦.Great build!

 

[karimwassef]

Glad to share

Hey Karim- How did this work out for you? Is there another thread with a status update on it that I've not found yet?

Pondering the idea of liquid cooling some LEDs for a Chaeto reactor. å

 

[karimwassef]

I've been too distracted by other projects to finish it! LOL...

We're moving and selling the house, so it'll have to wait until I set up the new one.
