View Full Version : New pressure fed pot design

This pot is designed for 21 psi, bottom fed dewer.
In the base is a Chilly1 block modified for this application.
As you can see the pot is pretty small and the feed tube extends from the center.
That tube goes to the base of the block where the gas will travel back up and out the spiral path. The block as decent mass so it will hold temps fine and with the hand crank valve I can regulate flow precisely.

My GPU blocks are done and should surprise many of you guys. :slobber:
Ill have update soon with benches, showing off the modified design.

That's very very slick, a clamshell with an LN2 unit, I love it. Always a kick to see your pressure feed systems in action. :up:

Its really cool to see more clever approaches to ln2 cooling than just different shaped solid cylindrical containers. I hope youll manage to get it work well.

Looks fun Fugger, temp regulation should be pretty good I think.

That is very nice. Great idea.:up: Should make solo benching very easy. I'm eager to see your gpu pots.

true true
the only problem now is getting the whole pressure mechanism and not having to sell a kidney to someone to get it hahahha

Gautam, nice rise on PCMark. Noticed you climbing the ranks quickly.
Ill have the GPU's completed (mounted) tonight or tomorrow for pics. I am sure others will follow in design simplicity.

:blushes: Was a quickie and I only had the CPU for one DI session. :) Not normally a PCM guy but that was kinda fun, the Vista benchin was smth else. :p: Don't worry, I probably won't find time for colder. ;) Entire combo just went in a case, stock cooler mounted. :lol:
The pressure fed systems are going to be the wave of the future with ln2, I just know it. Once we come up with mechanisms to effectively control the flow on the fly, we could achieve perfect temperature control and very easily fight any cold bugs totally maximizing CPU clocks with ease.

I do that now, ask Crotale. He had a chance to enjoy the rig in Taipei.

Doesn't sound like very much fun, I like to have something to do when I bench.

That looks interesting FUGGER. Has anyone here ever had a problem with freezing pipes/valves on a setup like this?

looks like a very interesting design.. i really like the clamsshell insulation/mounting bracket thing.. looks really awesome :toast:

Heh, there are a couple of concepts that I think would be sweet. I'm thinking having a system like a garden hose. If you're not clutching the nozzle, the flow would be zero. You'd carefully squeeze it to varying degrees for LN2 delivery. It would still be very interactive and would still require the user to be paying keen attention to temps. Perhaps this is somewhat like your system FUG?

very nice design, can't wait to see some results with it

Interesting design Fugger I look forward to seeing how it goes. Will you be selling the gpu pots? I just have to ask since somebody else is slacking. :rolleyes:
Since you seem to do the most with semi automated LN2 feeds I was wondering if you ever tried something like a temperature controller (http://www.omega.com/prodinfo/temperaturecontrollers.html). I think it may work well using a thermocouple, a PID based temperature controller w/ a 4-20ma output to a variable solinoid on an LN2 feed.

Woha... drastic change @ top [of da charts] with neat designs :D
Good Luck!!

Good job, especially with new mounts, but I swear (not to rain on parade) that I've seen this before. Mighta been team japan, not sure. Gotta give this a shot. And also, pressure regulator ftd (for the drip!)

Looking forward to those gpu blocks and your results Charles :up:

charles how is this going to work exactly
you will have to have separate valves on each pot to perfect the LN2 flow as different cards or CPUs may have different freezing points :confused: am i right
that means as many dewars as devices getting benches along with pressure devices and all

That isn't simple dinos22 :D

Why shouldent he be able to have a Manifold with 3 different flow hoses?
Na that wouldent be good because closing one would increase flow to the others because of pressure increasment:(

But when changing the flow for one you would increase the flow for the others...

You shouldn't change the flow since the dewar maintains 21psi. As long as each feed for example of three is 1/3 the diameter of the outlet of the dewar. I think output shoul dbe 3/8" so each feed to remain a constant would need to be 1/8" :up:

No, a CPEV controls the output pressure, regardless of the input.

Looking really good, looking forward to see some bench results and info about temp control aswell ;).
