So Here I am with first Test run of my Phase Changer unit.

Yesterday evening I have started working on the Phase changer.. till 9 PM I am finished all fitting and ready to fill gas a test run..

Since this is initial testing so I have not vacuumed the unit.. instead I have just flushed some gas through first and then just filled the R404a gas.. and started the unit.

Initial temp was good but fine tuning the capillary placement in the evaporator.. I was able to reach
-36C.. YES…COOL

Turned off the unit let it heat up to the ambient temperature.. Now again started the unit to check time used to reach a temperature .. for ambient to -36c in just 3 minutes.. and power consumption is just 0.4 amp …
(All analog and digital thermometer are calibrated in a Laboratory.)

Not tested with 200W- 220v AC of thermal resistance .. At full load for more than ten minutes temperature remains to -32C.. …
Mind I have not vacuumed the unit (It takes about 2 + hours).. after that I hope to reach -40C.. will do vacuum afterwards.


Now assembling the PC together and insulating the evaporator.. it’s 1am so should have a sleep now..

One of the coolest rigs in India.....most probably the costliest rig too...!
Would burn a "Grand Canyon" in the pocket!!!!! :)

^can it be bought under 80K price tag with all the stuff...if not then it could be costly rig.
And you are building cabinet it from scratch...hats off to you dude!!!!!!!
Do you have your own website??
Seriously dude you can make it a full time profession in building custom rigs....!

No website.. or business setup... just do modding for fun...

There is very little scope of taking modding as a profession in India.. Since i am from a small town.. so scope here is zero..

Update Soon.. Got my i7 2600k from RMA..
Just working on a Circuit to take over the Phase changer unit to Manual controll when doing overclocking...

Since one need to restart the board again and again while overclocking.. but a Phase changer unit ones shut down.. need a 5 -10 minuite hold before restarting..

To solve this i am working on some thing..

Once done will start Ocing..

Very nicely done. Really nice.

Question:
From what I understand, the unit will power on to cooling mode, once the temperature rises again. How long of a threshold you have in between, i.e. the thermal delta.

I am using a Controller to controll Unit under normal or OC condition..
I can set different profile with different temperature to be maintained...

Unit starts with PC turn on.. and turn off with shutdown.

But when we are doing extreme OC .. one need to change the setting in BIOS again and again and restart frequently... and need constant low temperature...

So a manual controller which will take over the automatic controller, to keep running the unit under frequent restart situations.. and maintain lowest possible temperature..
