Personal pages/Reflux cooler

In September, Alex Stalder helped me mill a 10mm groove into four old Pentium III heatsinks, to fit them onto the 10mm copper pipe after the thumper. I had tried with one, without a groove - it got hot, but obviously did not cool enough. I mounted all four as well as an 80mm fan.

2020/10/25 I distilled the 2nd 25litre gin bottle - yield was about 2.8litres of 80-85% alcohol. After that, the yield dropped quickly to 30%. This is the first run with the reflux cooler. I wonder if this nice high level of ethanol and the steep drop-off to 30% is due to that ? I will probably have to do a run on a proper maische to really be able to tell. Seems encouraging though.

More thoughts:

Use a bit of plastic to hold three fans on top of the heat sinks, pulling in air from below. attach it to an airduct (cardboard) going down the sides of the heat sinks, creating improved airflow.
