Lost In The Fog

Ok today I actually got some stuff done. Recovering from an ischias due to inflammatory from one of my lower back busted discs.... o_O

Got all the parts for the cooling block now. The next big thing is making the holes in the top disc for the water connections. Either a treading and use metallic connections with the option of having ball valves to adjust the flow through the block. Option two is to just glue plastic pipes for connection with no ability to change the flow.....

This is what needed to be cut out of the middle piece to make the space between the discs. Started with a 100mm circular saw and then routed out the rest as good as I could.

That's all the pieces, going to rough up the faces which is in contact with the next face to secure a good welding with the epoxi plastic I'm using to glue it together. Got some holes to drill through all the discs to.
 
I have no idea what I'm talking about but don't you control the water flow on the pump side rather than the light side? Seems much less fiddly.

First thing I will add is that the blocks will be in parallel with the pump.

Yes you are partly right about this shed. The main flow you set on the pump but water always takes the easy way. So the most flow/pressure will go through the first cooling block in line and then degrade the further from the pump you get. You can prevent this with higher pressure/flow on the pump or smaller size on the pipe/hose. But the easy way and most customizable is ball valves on the cold side of each cooling block. Then you can easy adjust flow over all.
 
Could you run a splitter at the pump and give each light its own supply line?
 
I was thinking this:

Suit yourself! Personally I would rather have three hoses I never have to touch than have to reach into the tent and fiddle with a ball valve screwed into the top of my light to make adjustments :). And if you needed to kill the water to the light you could do it without reaching into the tent.
 
Got hold of 1/4" threading tap today. Threading went smooth and easy also sanded all sides that's in contact to get a good plastic weld with epoxy. So tomorrow I will get some more bolts, valves, connections and epoxy and glue that sucker together. Then it's time to move on to the peltier cooling of the water. :)

So wait a minute your just gonna pump a puddle of water ontop of your light sandwich and use that to transfer heat to 3 peltier units? You are far more brave than I. Should be fun though

You never know if you don't try. :)

Will do a test in controlled environment with the light switched off to start with. The drivers are short circuit protected and got EB over this to. So IF a leak will develop the lights and the drivers should be protected... but sure, you never know until u test.

Cool if it works. :ganjamon:
 
Two words...silicone washers.

Instead of the metal ones on the backside? Will those apply enough pressure for the sandwiching?

I'd go silicon washer with a metal washer backing it.

I know nothing except that metal will never seal the microscopic holes that water likes to find. With silicone it's not just about how tight but how it expands to fill the gaps.

Seal it up like a dolphin's ass!
Watertight!

LOL!

Brilliant! Don't over-tighten though. Let the silicone side do its job.

[I am not an engineer nor do I have any experience with silicone washers...just a shitload of common sense.]
