Thinktank Revision 2.0
 
Ok.
I promised the the thinktank 2.0 worklog to Hardware Canucks.

Here it is boys and girls.

=)
------------------
Preface ~

For those of you that don't know , About 4 years ago , I created a submersion cooling based case/computer.
The machine , while completely under liquid , ran fine , but there were no spectacular temps.
I was dissapointed.I am going to rectify the situation.

:)
-----------------

Thinktank Revision 2.0 specs ~

Intel core 2
Mobo yet to be determined ; Asus striker if it'll go
Muskin extreme redline ddr2 pc8000 ( micron d9gmh )
Cheepo video card at first..
- The entire motherboard assembly will be Submerged in 99% Isopropanol alcohol , that is being cooled with dry ice.
- The system will consist of 2 separate tanks , the first being the original thinktank 'tank' (after modifications) , the second being a 'resevoir' for dry ice and alcohol.
- The resevoir tank and all associated piping will be insulated via the Vacuum jacketing method.
- The whole system is being designed to go below -100 C.....We shall see ....

Onto the very first pics !

Original Tank on half rack.This is the 'case' :

Here's the open rack with the tank ;

Now the two tanks and the vacuum pump. ;

What is vacuum jacketing you ask ?

Here's a shot of a vacuum jacket pipe :

It's a pipe inside a pipe , and you maintain a vacuum between them.The resevoir tank will basically be a vacuum dewar , same thing.....best insulation around.

I might make the piping from stainless , I'm not sure yet.

more right away !!

Ummmmm..... how good is your house fire insurance??????? :)

Hehe

The entire system is being designed with that kinda thing in mind.

The whole half rack is being setup to run a positive pressure nitrogen atmosphere,,,

----

Don't worry bout the Isopropanol tests...they'll be fine.

it's the methyl / diethyl ether tests that worry me...(assuming the hardware survives)

heh

Wow if they find your house in ashes they will assume you were building a computer-ignited bomb. You sir are crazy!

holy sh:censored: dude...good luck and be careful...cant wait for more :thumb:

BrainEater April 12, 2008 03:26 PM

Hehe.

No I'm not crazy , and yes I have fire insurance :haha:

Thanks for the words of concern.

Let me assure you however , I do actually know what I'm doing.Safety is my #1 concern , believe me.The entire machine is going to be surrounded by nonflammable gas , and I'll be building active solvent recovery systems.Even the blanket gases are going to be properly ventilated.

I managed to get my first vacuum jacket pipe put together today.

Step 1 : 1/2" and 1/4" soft copper tube ;

Sized and straightened ;

My jesus. I love the 25U rack though, been thinking of getting one and a few rackmount antec cases

BrainEater April 13, 2008 07:27 PM

Thanks man ! ...Racks are great.

This one actually has a story too.It's an original series Q-sound processor rack , that I've repainted in my clans colors..... It usta be a semi white cabinet , but I saved the plaque ;

I've soldered the first vacuum jacket pipe..... ;

Tank end :

Drain/vacuum end ;

http://braineater.kicks-ass.tv/miscshite/tt2_13.jpg

-------

It's certainly not perfect , but it's not bad for my first try , I think newayz.....It is getting an exterior 'seal' coat , so the solder joints are mechanical only ...

This is only a 1/4 inch line tho.....The main circulation lines will be 3/4 inch ID minimum....1 inch if I can do it.....But the piping will be a challenge for sure !

More in a few days .

Yea baby !!

Ok.......I am taking the 'backplate' from the original thinktank to the welder's. :

http://braineater.kicks-ass.tv/miscshite/tt2_16.jpg

Every hole inside the rectangle will be welded shut.....I'll be drilling new holes.

I have removed the top from the keg.

First I'd like to thank Mike and Ryan from Wildrose brewery In Calgary.Thanks for getting me the tank boys , I owe yah a beer....hahaha

Pressure let out , start hole drilled :

http://braineater.kicks-ass.tv/miscshite/tt2_17.jpg

Sawed off......same jigsaw from thinktank 1....pooor f'in thing ....hahah

http://braineater.kicks-ass.tv/miscshite/tt2_18.jpg

Top removed , ready for next stage ;



---------------

I have a bunch of glass ordered too.I'm making the original tank into a 3 wall Ln2 (hopefullly) container..

The tank shown will be going into another stainless steel tank just a wee bit bigger.......for the vacuum jacket.....
