I decided to make thread about the previous dryice tests with the 160w bench ive been using to measure containers cooling efficiency to get some comparable results which kind of containers work well and which doesnt.
I would advise to make this sticky (and perhaps take off some of those noob-guides) as there arent really much (if any) this kind of information available at the moment. Im not saying this testing method is very accurate but at least it gives some direction (this doesnt tell how much there is fluctuation between idle/load).
Testers contact surface area is about 3,14cm^2 and used resistor is rated 330ohm which gives 160w in 230v line (230v^2/330ohm=160w). Thermal probe is inside the 14mm thick copper die. If i was to make another tester some day it had adjustable heatload and more advanced temperature measuring.
Anyway here are the results:
And last here are some pics of other containers that i havent tested or turned out to be flaws like the sandcast aluminium container in the picture (+6c due the wrong alloy type). The copper version flawed in the making process as there was suction and i also put the sand core "bit" on the other edge But that was my first own casting so its only reasonable... didnt have the intrest to try another time as there wasnt copper castings going on the next day at the foundry. There is also pic from r1150 heatpipe dryice container which didnt work as it supposed to (-22c). I think there was wrong pressure but idea was good anyway. Ive also tested forced convection in the bench but i havent got success yet (+3c with pathetic flow). I think there is cavitation with the pump when methanole comes really cold because flow rate seems to drop really low (just as dr.cooling told about year ago when i told i will test it). This could be avoided by using different type of pump or liquid (or both). Its very intresting and potential (not to mention how easy it would be with SLI-setups and such) cooling method but needs more time and energy than i will have in the near-future.
I hope someone gets something out of this
