The main reason for aluminium over copper was the massive price difference. It’s not many btus of heat it’s not like I have an amazon warehouse but I currently use 30,000 btu of AC to keep my room at ambient
Even if I went the copper pipe with welded sheet ontop id need over 150m of copper pipe...
If you use copper pipe which would only contain a small amount of water I’d have to encase the pipe in solid aluminium somehow so that the components can be directly mounted to it I can’t mount anything onto a copper pipe. If the aluminium isn’t touching the copper entirely convection happens...
I’ve considered brazing aluminium to aluminium using sheet metal and a threaded aluminium bung but I can’t find any information on the strength of this kind of braze would it be strong enough?
pipe won’t work otherwise I would do that. Components need a flat surface to be mounted onto with thermal adhesive for conduction to occur directly to the water
I’m looking into other methods of sealing the end of the pipes first before I commit to welding based on the things you guys have said. Maybe I can find another way to seal the ends

That’s what I was looking at but I assume it’s completely the wrong type - I think it’s dc
i hAve a 15000L koi pond that the water flows through before going back to my heat sinks that removes any excess heat and takes the water back down to ambient levels of 25c even in summer colder in winter
cooling water is much more efficient than cooling air due to the heat capacity and the...
All those things are sorted and planned out already I didn’t include it as I wasn’t sure it would confuse as I had a welding problem not a coooing problem
Do you think it will be easier for me to solder/braze join those end caps above?
It’s a bit higher initial cost to buy the end caps but if it’s likely I will spend 500 quid on a tig welder and not be able to do it then it may be worth spending the same amount on the caps and soldering
no I’m not sure what your getting at?
It’s a hobby but I do make a small profit from what I do. The things I make won’t be sold but to be used as a method to cool my setup
Yes it’s a one off as I won’t need any more than I need to cool my setup
I’ve researched the subject but welding is new...
thanks for your input. The only other thing I can think of is to use some of these on the ends of my aluminium tubes and solder them in place but they are stainless steel is that possible?
The aim would be to no longer use refrigeration and rely entirely on cooling via water. A small water chiller will be used to compensate for air cooling if the room air warms up too much but conduction is a lot more efficient than convection so the water should heat up a lot more efficiently...
Currently the electricity used for servers makes profit margins for cryptocurrency mining so slim. Cooling with AC costs a bomb. I think it’s stupid to pay for AC when that heat could be used.
I want to custom build all my servers and directly mount all the components directly on the aluminium...
