Quad IC

[Gurgeh]

nice work there E1N - 20 mins to get to within a split whisker of coolant temp, that's very impressive!

i reckon you'll cleave 5-10 mins off that in a few months time!
very neat work, very jealous

Prolix - so the cooling water flows beautifully along the smooth inside of the pipe, and you get a layer of water heated by the hot wort closest to the pipe wall, so the middle of the water in the pipe doesn't mix with the water next to the pipe wall?

Yep, now if you could use the convuluted copper tubing....as in the US cfc's, then I'd be very interested in the results of turbulant flow coolant.

Might actually explain why the wonky less pretty ones work as well.

Could you put a ring in the pipe to aid turbulence, like force the water through a small aperture on entering the ic.

[Gurgeh]

or crimp/kink slightly with pliers here and there?

is the flow really likely to be that laminar?

[Aleman]

Actually it will become laminar very quickly, due to the effect of the smooth walls of the chiller . . . This is the reason why Convoluted copper chillers are so effective, they stop laminar flow forming.

Thanks for the kind remarks, everyone!

Must try the aeration idea, maybe with just hot water in the boiler.

Vossy & Aleman, did you mean a convoluted chiller like this? I was wondering how much the inner pipe is coiled within the outer...

[Aleman]

From the outside it looks like a normal CFC, but the inner tube has been twisted while soft so it looks sort of like that licorice you can buy, no smooth walls . . . no laminar flow . . .Someone did look into how much it would cost and even a sample length was 1000ft I forget now how much that would have cost . . . and the minimum order was a bit silly.

Aha... thinks... wrap 8mm pipe round a 15mm pipe quite shallowly. e.g. one turn every 100mm or so, then try to bend an IC out of the spiral just formed. Don't tempt me
