Building a dry ice container...

[Malachia]

i all guys, i am going to build a dry ice container, since the mach will go to gpu :banana:

well, now i think that i wil use a 40x42 chopper tube, now, my dubt is the basment... how much eight???

[twilius_basic]

The base should be 1/2" thick I think, from what I've gathered that is the best thickness for DI+LN2. The dimensions should just be whatever will fit on your mobo, usually 2.5" wide is pretty common I think :)

[Malachia]

1/2" in millimeters????

[Jvlk]

1/2" in millimeters????

That's Inch

1.2cm

Height is just what you prefer, I have 2 cpu containers, 1 is 20cm and the other 25cm.

[Stinger]

1,252cm more exactly

[gclg2000]

I don't see why it will matter wether its 1/2" or something like 3/8". Hell even 1/4"

[lalPOOO]

The thicker the baseplate is the less temperature variation you will get. However your temperatures will be a tiny bit higher because of the bigger baseplate because more 'cold' is spent cooling the larger mass off.

[LardArse]

It will give you much better load temps.
Go with 1/2".
DI is a lil different from LN2 since the heat exchange takes place 95% at the base while LN2 the base + containers inner walls. So you definitely need the thick base.

[Stinger]

so 1/2 is better than 3/4

[Malachia]

ok, i will go with 1/2" :D

[Jvlk]

so 1/2 is better than 3/4

Yep, 1/2 great for dryice and LN2

[Malachia]

i will search for 12mm, but i think that will be hard...

[cold_ice]

10mm are still ok.

[Malachia]

hum, ok i will search....

i founded the tube in chopper and in alluminium, wich one???

[Hilppa]

Take the copper one. It is much harder to attach aluminium to the baseplate.

[Malachia]

ok, i will take chopper one :D

a good(and easy) program to project the container in 3d???

[Malachia]

ok, i have found chopper pieces 50x50x10mm


tomorrow i will search for tube and good neoprene!

[sharp]

Where do you guys get DI?

[Malachia]

i take @ www.dryce.it, have a shop nera me...

guys i founded tubes....how hight i buy them???? 20cm????

[cold_ice]

Where do you guys get DI?
Linde, Airliquide, they all have dry ice. If you live near at the border to Austria you can buy 1kg for about 1.50€ in Graz. But I'm sure that you find someone who sells dry ice in Slovenia.

[sharp]

Thanks :thumbsup:

[Malachia]

i have bought tubes and chopper today, at the end i decided for a 70x70x10 basement, good for 478,A64 and maybe 775(i will try in a couple of weeks...)

here pics!

[enzoR]

what kind of a shop did you buy that in? i cant find copper on my area

[Disposibleteen]

you cant find copper? should be at any big hardware store chain, here in america we find it at home depot....

[cold_ice]

You can order it in germany, the shipping costs shouldn't be so high. This is a good shop, ordered copper several times here. They will cut blocks to the size you want.

@Malachia: I hope you don't have to use a ordinary hacksaw to saw the blocks to the right size :p:
I would take a 60x60x10 base, because you have to think about insulation...

[Malachia]

yes i know, in fact i realized only @ home the error.....but for 478 and A64 is ok, 775 must try...

[chefnr1]

Heres how i make mine :)

the tube is 54mm outside and 50mm inside, the plate is about 10mm thick :)

[Malachia]

insulation i need a thin but good think....



chefnr1 well done!!! how hight is the neoprene???

[chefnr1]

its not neopren its Armaflex insulation much better then neopren and with DI you can have 12mm to 15mm its enough but shall you go on liqud nitrogen you should probably have 20mm- 25mm :)

[Malachia]

thx, i hope i can do....i have the poblem that i have done it 70x70, 754&939 no problems, but 748 a little i will have.....

[chefnr1]

thx, i hope i can do....i have the poblem that i have done it 70x70, 754&939 no problems, but 748 a little i will have.....
whats the problem is it the mountin hole or for 754/939 have 89mm between the hole's and what is that you have done in 70x70, what is 748 for an socket??

[enzoR]

you cant find copper? should be at any big hardware store chain, here in america we find it at home depot....

not here. they dont have copper blocks, only pipes for use as water or gas pipes which are max 1/2" big :rolleyes:

[chefnr1]

not here. they dont have copper blocks, only pipes for use as water or gas pipes which are max 1/2" big :rolleyes:
here in sweden we can get both plates in wich thickness we want and copper tubes up to 3" bigger does not fit in on the mb!!

[enzoR]

just in a HW store? :eek:

[chefnr1]

just in a HW store? :eek:
it's a metal store they have all sorts of metal you just ask and they sell it to you they cut all you want :)

[sharp]

Ok i find DI :D 1 evro per kg.How fast di evaporate i mean,when you buy it do you start benching or it can be stored somehow like in a freezer(i was reading that freezer's thermostat will shut off the freezer due to the cold of the DI)? In what package do you get di?
Thanks

[cold_ice]

I stored it in a "insulated bag", which you normaly take to the beach for cold drinks. Maybe 1 or 2kg are evaporating per day

[FallenAngel]

There's no other cheap way to store DI? :confused:

[Malachia]

i buy it in "polistirolo" (try to translate, don't know in english :() boxes, that costs 5€...

[chefnr1]

i buy it in "polistirolo" (try to translate, don't know in english :() boxes, that costs 5€...
can it be plastic foam box :confused:

[sharp]

Probably he mean this

I did a search in google and I got this italian website but perhaps someone can translate it by seing the pics:

EDIT: Oops 'Sharp' beat it to me

[Malachia]

http://hem.wasadata.net/2501/turez/DI/DSC00105.JPG

exact :D

in italian is "polistirolo" :D

[LSANTHRAX]

polystyrene perhaps?

[cold_ice]

I meant a container like this

That was realy small pellets you got there :) that i am bying is like Malachia's size. youres just like snow to me :p:

[cold_ice]

Yes the pellets are very small. It's better when you can get them in this size

[Malachia]

yes, you need to use only a few of alchool with these pallets....

[chefnr1]

This is how low temp i get last i used DI on my X800XT PE using pellets size of Malachia's and with aceton :) http://se.msnusers.com/chefnr1segenalstersida/torrisprojektngotlyckat.msnw?action=ShowPhoto&PhotoID=117

[Malachia]

hem guys, i was saying about the box not about the ice :D

[Malachia]

mounting project ready :banana:

[chefnr1]

Looks nice just as i done with several of DI containers works well :)

[enzoR]

lol... its polestyrene i get them delivered to me in those boxes. all i do is drill a hole in the lid and put it in my freezer

[Malachia]

lol... its polestyrene i get them delivered to me in those boxes. all i do is drill a hole in the lid and put it in my freezer


hole in the lid??? lid is the upper part of the box??? why you do the hole???

[Malachia]

here the project

[Malachia]

here you are...

[chefnr1]

Here is one i've done:)

[Malachia]

very nice!!!

i need to lap the base now, how i can do it???

[chefnr1]

very nice!!!

use a very fine wet sandpaper go in circle on it not too hard just swing it around with it's weight dont push hard do it nice and easey :)

[Malachia]

fine how much??? number...i think 200 can be ok or not?

[chefnr1]

fine how much??? number...i think 200 can be ok or not?
i dont know if u have the same system of paper number! but i start with P600 an when it's klean copper i'll use P320 all black water sandpaper :)after that it shine like a mirror

[Jvlk]

i dont know if u have the same system of paper number! but i start with P600 an when it's klean copper i'll use P320 all black water sandpaper :)after that it shine like a mirror

I believe the whole world has the same system.

But like chefnr1 said, look for grit 600 , 800 ,1000 ,2000 to get it flat like a mirror.
But anything over grit 800 is overkill really, doesn't add anything cooling wise, only cool mirror look.

[Malachia]

yes sorry, i used 600-800-1000 and then "Cif", a cleaner very aggressive product....

[Nazaar]

when are we going to see some action ?

[Malachia]

in a week or two, i need to mod vga, mach and motherboard....

[[XC] moddolicous]

Take your time and make it great. I don’t know if you mentioned this, but what processor are you putting underneath this?

[Malachia]

one A63 754 3200+ clawhammer, not very luky, 2700mhz pelt cooled, and a 3.0 E0, nothing to say about this, arrived this morning, now i am writing from him for the first time...this evening or tomorrow i will test this with boxed cooler...
