The thing to worry about would be the possible chemical reaction to some of the juice. Thinking here of the tank crackers. With out doing some decent research there is no way to know if anything would be added to the juice using copper. The only way to find out is to do some tests and send the remaining juice out of a tank used in a test to a lab.
We know we don't want tanks made out of chrome plated brass, but this is because brass contains lead. Copper on it's own is soft so the question becomes what is this copper pipe made out of? Heating and cooling down can be used to harden copper. Some copper pipes are an alloy of copper and brass, more commonly referred to as red brass. It would be good to avoid an alloy.

Whoa there partner, your own 2nd link contains this:
I see a mess of nasty in there, plus three mentions of poison. It isn't so much the lead in brass that is the suspected culprit it is the copper. You can easily get lead free brass, red brass has 5% lead, naval brass or cartridge brass has 0%:

We don't know what brass is used in "commercially made" devices, hence the term Mystery Metal.
Annealing copper doesn't really work, it remains a soft metal. You can test this with a few inch strand from a wire and a lighter. It takes the heat, and still bends easily.
Copper is the element, brass is an alloy of copper an zinc, and possibly other additives like lead or tin. Again, just avoid red brass, it is the worst example. The use of "Copper pipes" here is just confusing.
There is a common argument that copper is used in water plumbing and therefore should be OK in our atomizers. However, copper plumbing forms a patina on the interior to make it even more anti-corrosive and it is antibacterial, so they don't break and kill germs. As for reactions with our juice, we are using a mixture more complex than water and is likely to contain some acids, particularly in the flavorings. This, combined with the addition of heat from our coils is bound to break down copper even faster, leaching materials into our vapor. As to some suspected problems with copper:

Everyone should make there own informed decisions, and while I really like brass, I prefer to keep it out of the tank or atomizer.

Thanks for clearing up what I was basically trying to say asdaq. It was very late over here when I wrote that not my best work but the general message came a cross.
No worries. This topic has been up before, but history tries to repeat itself. There are a couple of new threads with people wanting more copper in their juice.
Thousands of years of use in cooking seem to suggest copper is a fairly safe option for food contact. Keep in mind many foods we boil in copper pots are acidic, and some are basic (i.e. pH > 7). That being said, there is always the potential that the reductive environment of ejuice (as in negative redox potential; opposite of oxidizing) might lead to the formation of toxic Cu+1 salts or organo-metallic compounds. There is no evidence for this, just pure worst-case scenario speculation informed by my own understanding of chemistry and toxicology.
In the final analysis, my personal opinion is that pure copper in contact with eliquid would be safe, however I'd recommend against this, because there is some unnecessary risk involved, provided that other much safer alternatives (e.g. glass, stainless, various plastics) are readily available and inexpensive.

Basically what I'm trying to do is find a tank material that will also double as a heat sink for a voltage regulator chip, so as the IC get powered on it pumps BTU's into the E liquid making it much more easier to flash and hopefully increase the efficiency of the batteries.
Now why I think this may work is because E-liquid contains glycol which is used in HVAC systems as a form of chillwater.

Interesting idea. I've been toying with some atty designs that would use the waste heat to pre-heat the incoming air stream.
from the research i have done(after buying a copper tobh by the way)i have come to these conclusions. As there is some risk to useing copper there are some things you can do to mitigate the risks and use copper relatively safely. First try not to use that atty for known acidic juices and tank crackers. Also do not leave e liquid in the atty and wash it thoroughly and scrub with a toothbrush when done using. The goal is to not let it tarnish and build up the toxic slats. Lastly try to keep the coils a little farther away from the copper atty wall, so it doesn't get as hot. If the deck is stainless steel and the chamber is copper I feel it is safe to you as long as you take precautions and maintenance steps. The fact that it will look amazing on my custom copper panzer with custom copper drip tip, has me mitigating and overcoming the small dangers involved. If you want a material you never have to worry about and can leave you juice in use ss, but if you want that sexy looking copper atty then just be advised it can be safe with the proper care and common sense. Will my copper driptip and copper tobh be my all day everyday atty? the answer is no, with precautions and work i feel its ok to use, but risks increase if you use it all the time everyday with all juices.

With caps, you could consider having the outside copper plated for aesthetic purposes while leaving the inside untouched. You will want to have acid plating done, as other plating types for copper plating are not food safe (some use cyanide).
