Hello all,
I am brand new to watercooling trying to find a wb with low resistance to try a new cooling idea. I am going to try to cool a chip with no pump, using a thermosiphon - has anyone seen this done before?
Basically, a thermosiphon is natural convection that is caused by density changes as the temperature of water changes. A thermosiphon system could cool a processor with no moving parts (if there was enough heat transfer area), but would probably need a fan to get enough heat transfer to keep the fluid at a reasonable temperature. Thermosiphons are dependent on the difference in bouyancy between hot water and cold water and require an elevation change to work.
The following link shows a schematic of a thermosiphonhttp://www.sunearthinc.com/sunsiphon_system.htm
I have to admit I got this idea from cooling mechanical pump seals
ftp://ftp.aesseal.co.uk/downloads/pub/literature/L-UK-SSE10.pdf
The pdf has a picture that shows the sealpot connected to a mechanical pump seal - substitute a waterblobk for the seal - and you have my desired setup. I've been told that a 10°C difference between hot fluid and cold fluid will provide sufficient (1+ GPM) flow for a pump seal.
Does anyone know of a low resistance waterblock that might work for this application?
Thanks in advance,
Aaron
