Scratch Build – In Progress ECI 33+ (3 Stage Cascade) - Stage 1 Completed

/\ woo makes 2 of us

 

Table 1 done. Milling machine going on up tomorrow.

 

Table looks great mate, very sturdy.

 

Winch + ceiling beam = Mill on Table!
I'm happy it made it, table seems more then okay, but conducts vibration a bit much.
Going to get some more MDF under it, get it all bolted down. And then figure out why the spindle ain't spinnin!

 

Nice design for the cascade. I always loved vapor cooling. I know eventually I want to try my hand at this kind of stuff and learn how to do it, but funds are insanely short... and so is my attention span... haha

BUT good job so far!

 

i wanna get a mill good luck

 

Everything moved over, so time to start laying out parts.
Might have a lead on the condenser I'd like for this, so the front is a little empty.
Compressors that seem "used" are working pulls from my own personal cascade that well, I built and never got around to finishing. So they're brand new still.

Layout time.

 

This is gonna be sweet.

 

Yep, going to start prepiping. Have to roll up these huge heat exchangers as well

 

So I take it that the coils over the compressors in your render are the heat exchangers? Is it going to be 2 tubes next to each other or something awesome like a counter flow tube in tube heat exchanger?

Or are they the 2 blue cylinders pictured above, and you just have to stuff them with coils?

 

The heatexchangers are indeed up in the air, they will be sealed in a large box enclosure, and yes tube in tube counter flow heat exchangers.
The two blue cylinders above are the Red ones in the renders, which are oil separator devices.

The benefit of using heat exchangers like this, is the first heat exchanger will effectively create a better insulation measure for the second heat exchanger!

 

So nosying around online... appears that you played around with another one in 2007? revamp of that project?

Whats next? add a few more stages and compress and cool liquid air and keep a mini dewar of that on top of a CPU?

 

Yep built another one a while ago.
This one has more controls to it, more tunable. Smaller (and denser!) and more powerful.
The features list on this is a mile long.
I haven't even gotten to the custom motherboard tray with mounting brackets for this.

Even a 3 stager is a lot more power then we need these days, I don't see a need for more stages. Although the next one might get a "half stage", or a subcooler to boost performance even farther at the expense of adjustability.

 

I decided since I'm already over budget by $700 for this project, I should try and make some more cash for it. So expect to see another project, a nice quiet and small single stage on a double H frame coming up soon. I've got it half done, so I better start that project log soon.

Brazed the first suction stem on compressor numero uno. It's nice to do them like this, since they'll shoot straight up to the heat exchanger coils. Nice and easy to insulate.

 

Heat exchanger time.
You can never have enough copper.

 

Making some fitting attachments.
Cleaned and shined;


Survey says...
OIL SEPARATORS!

 

That's some massive cooling. Almost to the point where you should just get a beer cooling system (called a power pack) and just cool your PC with that.. add some beer on tap while you're at it and you'll have the most popular computer in town!! With what you're doing now you'll just have the coolest ... (I'll stop myself here and smack myself for bad puns) Still -150C *eyes popping out of my head* that's pretty hardcore. I'll definitely be paying attention to your project. Good luck.

 

Thanks. This will end up coming to conventions with me too.
Part of having the biggest badass cooling machine around, is it helps sell the little ones a bit.
Like the other one I'm working on.... :whistles:

 

And it begins lol.
