Default Grizz's DIY Heat sink & LED build / showing all colors

I put all this in my build tread for the 300 gal 8'er but thought I should do a DIYthread to make it easier to find.

I finally got a chance today to start building the heat sinks for this tank. I have decided to do 2 - 39" x 12" heat sinks both will have 136 LEDs but will have room for more.

Got my main plates of 1/4" aluminum cut & 48 pieces of 1/8" x 1" aluminum flatbars as well.





First 5 flatbar fins tacked on:



Now 10:



15:



20:



And finally the last 3:





As you can see in the 2nd last pic I removed the very first flatbar fin, yes this was planned because I am going to wrap the whole out side of the 1/4" plate with some 1/4" x 2 1/2" flatbars.

I cut some 2 1/2" strips out of a small sheet of 1/4" aluminum on my tablesaw, then cut a notch into them for my 1/8" clear acrylic cover.









Added a 1/4" x 2" strip across the front but have to add something below the groove to hold the acrylic flat.

LED side:


Fan side:

Added a couple pieces of 1/2" square tube to mount the fans onto the heat sinks.

No tony not TIG welds, I have an aluminum spool gun for this type of work. It's easier to tack with the spool gun vursus needing to use 2 hands for the TIG.

I just used what Martin had figured out for a 48"L x 24"W tank to get an idea of what I needed & asked Martin what he thought I would need. I was going to go with 4 - 12" x 12" heat sinks but decided to go with just 2 - 39" x 12" so that I had a 6" difference on all 4 sides of the tank & between each heat sink.

Any time your down here drop me a line.
