Bending thin wall 8-10 mm SS tube - chiller?

[aamcle]

I'd like to make an immersion chiller for a plastic beer barrel (like this https://www.hopandgrape.co.uk/beer/beer ... allon.html) I like the ones with with the small caps they leak less often.

What I'm thinking of is an loose spiral like an open corkscrew that I could mount through the cap and twist it into the barrel.

The SS tube would contain a plastic inner tube that would allow the recirculation of coolant from a PC liquid cooler. Coolant would flow down the inner tube and back up the outer tube cooling the beer, obviously the outer tube is capped.

All I need to know how to shape the outer tube, if you are able to tell me how to form the bends I'd very much appreciate it.


Many Thanks. aamcle

Sorted

but it would be cheaper to buy a second hand fridge!! Now if only I had space

How did you bend it? Is it as easy as copper? I would like to fit a herms coil to my hlt - I have copper and pipe bending tools but I would rather use stainless...

don't PC liquid coolers just cool to ambient? or have things moved on since i last looked at this a decade ago?
stainless steel has quite a low thermal conductivity

i think you would be better getting a fridge.

If a PC cooler wont go low enough then a plane Peltier device and temperature control would or recirculate coolant from a fridge but with more thought a cheap fridge in the garage is looking better and better. Ferment in it or hold a barrel, cheap, easy but bulky...
