Copper tube in DWC?

Hmm...
it’s not just a fungicide but is also anti microbial. Also great for killing snails in a fish tank.
As an anti microbial, it would kill the beneficial bacteria that are part of helping roots uptake nutrients. I’m not sure if it would have any negative reactions to the plant, but would be more concerned as to how the copper reacts to all the salts in the reservoir.
If price was no concern, i would try to use stainless steel tubing. If you do come up with a heat exchanger system, I’d be very interested in following along for ideas.

Definitely suitable
You would consider this suitable even though it kills all bacteria? Have you tried it? McMaster Carr has aluminum tubing for sale. Any reason not to use Al?

What is your plans for chilling the water? Pumping?
There are some great peltier in-line cooling modules on Amazon that i have been eyeballing. Unfortunately they consume a lot of electricity to run, so I’m looking for other ideas.

So, if this was sitting on the bottom of a bucket and had cold water 40F running through it, would it cool the water to 65-68F? Hmmm
Smokesteve have you ever tried copper in a dwc? That would be the simplest solution. Does DWC require good bacteria if there is no bad bacteria?

I am looking at one of these with an Arduino Nano to monitor temp to turn it on/off.

I haven't although I have some knowledge on the subject through an aqauntence. Ph 5.5-6.5 copper oxide formed on outside of the tubing, reducing leaching potential. Then again if you have a cheaper option go with that. I know of one guy who had success with it.
