any DIY heat pipes?

Lol?
Personally I think this would be fucking awesome for a borderline passive setup utilizing less cobs + more watts per cob
I probably wouldn't be making shit like that though, I'd just go with some heatsinks from CDI (https://www.cdiweb.com/Manufacturer...ype=707&manf=397&cate=397:3&NavType=2&sd=true)
Than what? And at what cost?

You realize the biggest sink on that whole page was 50mmX50mm? That's good for like 10watts.
i want to fully utilize all of my vertical space so i want small lights. I dono

So you want 4 cobs to power a 4x4 tent with 2 cobs each mounted onto 2 of those joined heatsinks?
Heat pipes simply move heat quickly from point A to B, you still have to do something with that heat when it gets to point B.
What is wrong with a normal aluminum heatsink without heat pipes? The ones people build on this forum are already quite thin.
I think 8 total COBs in a 4' x 4' running them at 100 watt each
all the data I've seen suggests they work much much better. esp if they are made from copper. the copper heatsinks / pipes to aluminum fins is what I want

You get substantial PAR output per watt improvements if you run less wattage through the chip. Even 75W per chip is significant, and less watts means less cooling required.

I'd reccomend extruded bars then brutha. You can run 4 on a 36" 5.886" profile heatsink usa setup at 64watts ec (hlg-240h-c1750) with 2 140mm fans on top with almost NO heat. It's a total of like 3" wide maybe if you run bare cobs without any optics. (Reflectors/Lenses)

Some have used those heatsinks with LED setups and not had as great a success as they hoped. Mounting the cob to the copper and aluminum tubing is also difficult because it's not properly level and has cracks between the tubes where they join. I see you want a plate between them but how well is that plate going to transfer that heat to the copper and aluminum tubing and into the fins? I understand your desire to do something somewhat different or neat looking but I don't think you'll get the desired effect you're looking for. I think you'd be better off getting pin heatsinks or the extruded variety like so many here have used. Instead of risking your time and money on something that might not work well, why not insure you get the cooling effect your setup will need running those cobs so hot.
