Pumping Liquid Nitrogen SOLVED by Rich Grise
Rich Grise wrote: How about two dewars? One gets filled while the other drains onto the heat sink. *There's* that Rich Grise thinking out of the box that we all know and love! As with most great ideas, my first thought was that I should have thought of that -- but I didn't. The one being filled can be vented to the room. No back pressure. The one cooling the CPU can be vented through a standard pneumatic pressure regulator, and thus the 2nd dewar will self-pressurize to achieve whatever flow rate I choose. Even the switching is easy; there are many small hydraulic valves with teflon interiors that can handle liquid Nitrogen. Brilliant! Somebody give that man a $200,000 a year job inventing things... -- Guy Macon http://www.guymacon.com/ |

It's sure to be quite cold, you know. :-) ....and the N2 generator has to strip out the O2, CO2 and H2O, so feeding it dry, cold N2 gas instead of air would seem to be something it would like. I wonder if a watt-meter on the power cord will register a difference? -- Guy Macon http://www.guymacon.com/ |
