Ham's single stage 2

Woah!

Thats one groovy piece of kit. I wanna see what its capable of, looking forward to some pics of the benching etc. Make us proud. :p
 
Nice tight superheat cooling coil there on the suction behind the evap! I'm not a fan at all of the flare fittings, you used any sealent on them as a back up? What leak presure did you try? Look good non the less dude
 
Tbh I don't like the flare either, but It's cleaner if I chose to mod/change the evap this way. Tested to 110psi.

Shes up and running now. Holding another cellery northwood to sub zero (highest temp was -4 on cpu) @ 1.9v, varying between 3.5 and 4Ghz.

Pics to come :).
 
As promised, a load more pics. All be it kinda squished by the re-sizer.



Unloaded evap



My 'Load tester'



Loaded evap temp



Bit of benching, all be it with an appalling mount.

Insulation isn't sealed yet as while it handles the cellery fine the cap tube might need adjusting for it's next victim. All is looking good though. Pressures were about 5/130 loaded and its SO loud...
 
Because its the only AGP card I have.

This is a Celeron Northwood 2.7ghz, if anything the 9800Pro is overpowered for the CPU. Im clawing up a few hardware point with it atm.

Need some rubber and a new mount kit before anything more modern is undertaken.

Thats less than 260w and your dropping to -4 under load!!! What gas you using and length cap. Tuning is way off!!! Oh and test with Nitrogen to 300PSI, 110PSI is not enough! Every part i make, every unit i test, built, mod, fix it's put too 300PSI. Why saftey is paramount!
 
First off its -4 on the CPU. Meaning though the thermal paste, IHS, my unreasonably think Evap base and with a bodged mount left over from the last build. The probe on the evap, as shown, was running -37. Its not a massive load (nowhere near 260w, where ever you plucked that figure from), Its a starting point.

2.3m of .031 cap and R290.

I think you should take a read of this thread with regards to pressure testing.

Ham,

I build units daily, i'm just finishing my HVAC corse off to be able to do this legaly and 110% safely. Plus most builders test at 300PSI

Got a link to a build thread? Surely with that many builds you have at least one thread with a finished unit? :rolleyes:

Ham... that is decent performance with r290. When you get the mount straightened out you will probably get even better cpu temps. I think you did an excellent job with this unit. R290 is not the best for holding a load, but it does a great job for something that is so easy to get, just use common sense and keep in mind that it is flammable.;)

I like the flare on suction line, I'm planning to do the same on a rotary build soon so I'll be able to compare some different evaps easily.

I don't see a need to flood the forums full of my working. It's showing off advertisment. Some buyer, end users don't want there unit being showed off everywhere. I don't take photos of every unit ether.

Nice one mate, is that fan by the CPU all you really need to stop condensation forming?

Also, loving the Kenny in the background on that cabinate LOL!

No, the fan is just to keep the PWMs cool. They were hitting the worng side of 90° without it.

Kenny is a money box :D. Stuffed full of coppers and silvers. Weighs about 2/3Kg its so full.
 
Can I ask what actually are these? I think I know what it is but I'll wait for someone to say what it is before sounding stupid;).
 
They're heat pumps. Work using the same principals as a freezer or air conditioning unit to pull heat from the source.

Might have a bit more to show after next payday ;).

So I was kinda right lol. I thought it was from a freezer:D.
