Also, with all the surface area of the chamber, evacuating would probably just make the walls cave in. The only way to prevent that would be to put in some sort of spacer. But the spacer would conduct heat from the outside to the inside. Much less of a hassle to do as sweeper has done.
I know it is hard, but it would be cool thoughQuote:

Also one quick question. I am assuming you are going to use copper pipe because of the pressure (though you could possibly use special braided tubing), what connector types do you plan on using ie:
Flared vs Compression
NPT vs BSP.
Ridged vs Soft copper

I've attached a few pictures of the wire loom as request...it may be a little confusing of how it will work, but you will get the idea once you see it installed.;)

Damn that's tight (must've missed to thread up until now).
But holy hell, you've got cash on your side for sure, and the tools to get the work done.
Keep us updated please :up:
I think I understand, you have differing size holes for the different diameter wires. 8 small holes, 2 medium size hole, and 1 large hole. You have the block split so you can put the wires through without taking off the male or female plugs.
What are the diameters of the small, medium, and large holes?
Are the two medium size holes for the pipes or are you going to have two separate holes just for them?
How do you plan to insulate the hole with and without wire going through them?
You got the idea :yepp: The hole sizes are 1/2" to 1/4" and the two 3/8" holes are for the evaporator tubing. The insulating part is a little harder to explain. You have to keep in mind this is a double wall chamber system. The wire loom will be installed inside the inner chamber and the wires will pass through to the outer chamber. Inside the double wall system the wires will be insulated and sealed air tight. On the outer wall, there will be another insulated enclosure added for closing the penetrations on the outside chamber. Basically, there will be two insulated air tight systems for the wires.Quote:

anything new?
Awesome work, I saw some of the earlier posts and nice to see it coming along quickly. Looking forward to seeing the end result in action.
Sorry I haven't post any pics lately. I've been working on the system....but ran into a few problems. I had to completely rework the fluid distribution block and receiver tank, because they did not fit well in the cooling chamber and the Y-strainer interfered with one of the condenser coils. But, the system is starting to come together....pics will be updated soon!
I'm also thinking of changing the POE oil in the compressors. I read Solest LT-32 POE oil is designed for low temps and will extend the life of the compressor. I have a gallon of Solest 31-HE POE oil, but it is designed for medium temps and I'm not sure if I should take the chance of using the oil.
What do you guys think.....use the Solest 31-HE or buy the Solest LT-32?
Update pics as promoised!:D As stated in previous thread, I had to rework all the liquid flow parts inorder for them to fit as planned in the cooling chamber. I will start on the mobo tray and routing the wires in the chamber this weekend. I'm also working on the compressors and hope to start up the cooling chamber to see what temps it will hold after the holiday.

great work :clap:
That block is so sexy with those stainless lines. :up:
Thanks for the compliment! Glad to see people appreciate my work. :D
Yep, WAY out of my league, wish I had those skills. Awesome work and attention to detail, can't wait to see the results!
A few more stupid questions.
Why are there 3 ports on one of your distribution blocks but 4 on another?
Will the orientation of the motherboard be vertical or horizontal?
What are the dimensions of the inside of the chill-box?
How will you seal the seam of the box to cope with sub zero temps?
Will the box have an insulated metal panel like the other sides of the box or will it have a transparent window?
If it is a transparent window:
What type of material will you use for the window?
How do you plan to control the condensation on the outside of the window?
Sorry to take up your time but this is intriguing.
When the receiver tank was originally made, I added a extra port to access the tank from outside the chamber to fill the liquid loop. Not sure I will use it....if not, I will block it off.Quote:

The inside dimensions of the cooling chamber is 16 1/2" H x 19 1/2" W x 15 1/2" D.
Are you referring to seam outside where the two chambers were assembled? If so, the seam will be caulked with silicone.
There will be a removable 1/2" thick transparent window which is made of laminated polycarbonate ( AKA Lexan ). Laminated polycarbonate is two layers of glass heat treated together with a rubber layer between them. This makes the glass stronger and acts as insulation when exposed two different temperature conditions. The glass is used in high security facilities such as prisons and jails. I should know...I build prisons for a living.:shocked:
Hope this explains ;)

What can I say that has not already been said. Awesome concept...great execution...incredible display of skill..brains...coinage.
I can only hope some of that will rub off on me :)
Keep it up!
Thanks CyberDruid for the support! The members of this forum inspired me to build this system....I just put a little imagination and skill of my own into the design.:D
Great project in making.
One thing I am not sure is how much turbulance of corrugated line will add to resistance of loop. Hopefully the pump is big enough to overcome it.
I don't think there will be enough resistance to matter in the liquid loop, because it is design to be a high pressure system. The pump is capable of 300 PSI.....I will be running at 150 PSI. :shocked:Quote:

Thanks for the advice!
Sweeper, you sick sick sick dude! I can't wait to see this done, it's gonna be mental!
How do you figure it will be running at 150 psi? and why would you want to do that?Quote:
