I've been working on some interesting container designs for quite some time, and I've finally figured out a design that should work very well.
I'm not wanting to build a traditional container, but rather build something that nobody has seen before, something with a new concept, and I think that this container will be one that will do very well...This is thought up after hours of concepting...

If you look at the image you will see the outer walls, then you'll see a taller inner tube which will be brazed to the block. The block will have 1/4" drilled channels, and a 3/8" hollow core to allow flow throughout the block and to add surface area.
The "cap" on top of the container will be cut to allow the inner tube to stick out of the cap, and it will be welded so that the inner walls are sealed completely. There will be a barb on the top of the cap for the line running from the dewer. The dewer will be pressurized at around 3-5PSI and will use a needle valve which will allow the pressurized LN2 to push through a copper line into the barb. Once the LN2 enters the barb on the cap, it will fill the outer chamber and be forced to push through the block.
Once the LN2 pumps through the block, it will then evaporate out of the inner tube. I will be building a flow chart to figure out exactly what pressure the dewer needs, and what height the container needs to be for optimum functionality.
It will also be possible to place a reducer cap over the inner tube that will reduce the opening to 3/8", and use a "Y" splitter. With a Y splitter you can add two copper lines that will run into two GPU containers and allow cooling there as well. So, basically with a "Y" splitter you would have a full LN2 loop. Of course you would have to run with slightly higher pressure so that the LN2 could be pushed through the lines.
Firstly though, I won't be running the "Y" adapter, that will be later on. First I will be working with the design just to get it all working smoothly. It will take quite a bit of calculations, but overall everything should work very well, and be one hell of a beast for LN2 cooling. ;)
