Using a House's Concrete Foundation To Cool a PC
Agg writes "Well the slab gets poured on Wednesday so I thought I would sink 6 meters of copper pipe in the slab so that I can run my water loop through it when the house is finished. I hope to have water year round at about 16deg [about 61F]. No need for radiators or fans with chilled water coming straight out of the slab!"
The steel rebar and the copper pipe being in close proximity will make them act as electrodes on a battery. This will cause the steel anode to slowly be destroyed by the chemical reaction.
Is it a practical concern in your case? I doubt it, but if they haven't poured yet, it wouldn't hurt to wrap the copper pipe in some PVC tape. This will reduce the thermal coefficient though. Maybe just do it where it passes within a couple inches of the rebar.
Why? It's very similar to what they do when laying radiant heat into the floor (which is very nice btw, over ducted heat, helps with breathing problems).
Also, like a previous comment suggesting, maybe you should look into radiant heat tubing over copper.
There is a data center in WA state that keeps half of its' property as vacant land for the sole purpose of using it as a giant heat exchanger. Looks like about an acre. They have piping about 16 inches underground throughout the field. I am told it works great.
I judt got a nre Kinesis keybiartf so please excusr ant egregiou typos.
That is why I wondered why some data corp hasn't bought up the old Titan 2 missile silos we have here in AR and turned them into datacenters. They are VERY deep in the ground, so you have natural cooling there, they are on the side of a mountain with lots of wind, more cooling, and if you put the racks into the silos themselves you could have fresh air blowing straight up and out through the silos. there are also lots of fiber lines running through that area, including dark fiber left by the telecos during the dotbomb. Not to mention with those big steel doors and hardened everything breaking into your data center would be pretty damned difficult, if not impossible. Oh and we have nuclear power here, so electricity is cheap compared to surrounding states.
It always seemed to me that with datacenters needing so much cooling these would be a natural fit. The military has done all the hard work, and from what I heard they sell them pretty cheap. One guy even bought one and turned it into an underground house for his family. Just always seemed to me to be the way to go.
ACs don't waste your time replying, your posts are never seen by me.
