Rio's Container

[Rio71]

hi,
here my theory and practice of building an container for cryo.

first of all, i watch lots of treads, pics movies etc also here.. thx for sharing :toast: .. here is my..

my brain was heating up and smoking.. :D
this container is only for socket 478 (p4 or actually aopen i855).
i measured around the socket, and find the biggest possible hose, is 64mm outside and 60mm inside.
the baseplate has the same diameter like the retention-module.

- first, cutting the hose to near 210mm long. i have not so a good feeling with the "super"long hoses like 400mm or so.. dunno.. :shrug:

- facing the both ends of hose on a lathe.

- now hammering around 10mm of one end from inside to outside to 90° angle. (this makes really muscles.. :D) pure handmade, using a roundet hammer peen.
this is for a perfect thermal-transfer from hose to baseplate.
i made a steel form-hose over the copperhose for helping me.

- now, in a lathe facing the back-fold for still better thermal-transfer and small usage of solder because of a very small gap between.
outer diameter of the ring is also reduced for not wider as the baseplate.
- making the baseplate, diameter see engineering drawing, and drilling cone-holes in the center.
cone for increasing the surface and bubbles can't hold-stay in the holes and can't blocking the surface.

- now add flux, aling the hose and soldering it together.

- finally bringing the bottom of the base in a flat condition, using sandpaper an a straight edge.

early i would made a pin setup with copper-pins for increasing the surface.
the pins are hammered with an selfmade press tool.
you can see in the pics some are ok, but most not.
i tryed long optimized the tool, length of pins, hole-diameter, deep and so on.., polished the tool inside..
but i give it up because the pins stick more in the tool as in the plate.. broke up ant the tool was hit.. :brick:

with the cone, im happy'er because the thermal-"way" is much shorter now and easy'er to made.


i have made two of the containers, the first has the rescue'd base from the pin-mounting accident.. :D :D

I think that you should use the pin method instead......It'll handle better the full load temps on a heavy and long time bench.....

[Rio71]

thx
yes, this project is not really death.. im thinking about.
possibly the better way is not pressing the pins in to the base.
i mean soldering it into is better an made better contakt and deeper seating.
with pressing in can't go safe the pins are deep in the hole AND fixed.
with a little gap, flux and soldering it schould be a lot better.

but temp-prob are not my problems.. :)
i run an pressi celeron on it with 1,600v on ic7.
at cpu priming: if the last di-pellet sublimated and aceton was clear, it need 5-6 minutes befor the hardware-doctor-button come up from -40°C.
in the future, i will drill an 3mm hole in to the base for adding an thermistor for direct measuring the temp with mm.

thinking.. will made an third container with pinbase and can compared it direktly with my next 25kg (http://www.xtremesystems.org/forums/showthread.php?p=838994#post838994) di-fun.. :D

here are the pics of action at last november and further screenys are postet on my german review. (http://www.tualatin.de/phpbb/viewtopic.php?p=112217#112217)

whats the purpose of those plastic round things?

[cold_ice]

Do you soldered the tube to the baseplate?
I had problems with leaks when I soft-soldered them, after benching with dry ice I got small leaks often. Until this time I only braze such containers.

[harleybro]

That's really a beautiful container you've made. :slobber:

[Apocalipsis]

Very nice work there m8, a pin style container could be fantastic, dont forget to show it when finished :slobber:

[kamaleon]

how long can you run per filled tube?

[vapb400]

very nice!!!

[Zyklon5]

Great craftmanship Rio. What results do you think you would get with a thicker base plate like 20mm. Does the increased tube thickness help 4mm it's pretty big :D ?

[[XC] moddolicous]

Thats a really nice container there rio. Like cold_ice said, I would braze it, but so far so good.

if you look carefull you will see that the 60 and 64mm is from the 2 side's so every side is 2mm;)

[Zyklon5]

Thanks Jort you're right .. silly me.

[Rio71]

tanks :toast:


whats the purpose of those plastic round things?
this is a lid for better isolating and lesser "coolinglost" through the port



Do you soldered the tube to the baseplate?
i made the gap very small an the contact area is big.
a very blank made surface and good flux give me an perfect flow of solder.
i never had problems with..



how long can you run per filled tube?
with pressy is running full load, i need 3-4 full of the pic-listet spoon all 15 minutes.
this makes the container near 1/2 to 2/3 full.
im using an short-time-bell because of all the fun.. don't forget it.. :D , the consumption was very constant.

mmm... 10 massive mm are still ok too but i think 20mm is to much.
the inner-thermal transfer is here no more optimal.
tube thickness of 4mm would be a little bit better for thermal-transfer, but made a bit lesser usable volume inside.
... is not really matters but 4mm hose possible not available.

[gkiing]

looks like you stuck your hand in the dry ice. That's not a good idea.

[G H Z]

His typing seems fine;)

Those are very nicely done. I was thinking of a cap myself. Did it make for less DI used? Do you use Acetone as solvent?

[BigPanda]

have you tried it with bigger pellets of dryice or chucks of it to see if it makes a differance? those bits arre nice and small i would think they would drop the temp a little.

[Rio71]

hi,
yes, i using acetone as solvent. (like the bottle says in german "azeton")
i never using other liquids, but im relly happy with this.. and i have anough of them in my garage.. near 40 kg.. :D



this session was my first one and only up to day.
this small bits calls pellets, and my supplier provide pellets, nuggets, disks or blocks.
the costs per kg pellets or nuggets is the same.. so i used the pellets.
all i cans say the pellets are VERY HANDY.. absolutely nice. :banana:

[cold_ice]

Yes Pellets are best

[vapb400]

Can you link the tool you used to bend the tube (seems you call it a hose) at that 90 degree angle? I can't really understand what you are saying (otherwise your english is great!) that looks amazing. Great job!
