1HP Rotary Cooler
 

Hello everyone,

In fact it's my first serious unit. It took a lot of time to build this, but it wasn't wasted time ;)

Just an ordinary, quite strong SS. I'm pretty satisfied with the results (-41C @ 250W, -46C @ 180W, -54C @ idle). Maybe it can be tuned a little better (it also depends on where K-type probe is located, I've drilled small hole on the top of evap, bcoz for now I'm mostly interested in overclocking, not the lowest temperature ;) ). I've tested it few days ago, and on E8400 @ 5,2GHz 1,8v there was something like -48C what is nice ;)

Compressor - Teco KETC176 10755 btu
Condenser - 25x25x5cm, 4x 120x38 mm Nidec fans (10V, 0.5A each)
Suction line - 80 cm long, 19 mm thick insulation
Evap - stepper, 42 mm diam, 40 mm, my production
Expansion valve - 0,8 mm captube
Refrigerant - pure R507
Baseplate - stainless, 35x50 cm

250W load

Very nice work! Doesnt get any cleaner than that :)

Hey BartX nice to see you over here (was just PMing you over at OCN)

Sweet looking SS you have there, very clean :)

Nice and tidy build bartx, what was your final material cost?

Sweet build man

how does it hold on 1024 ?

Very clean! Is there a switch hidden someplace?

Very nice clean unit mate! I love it! :thumbsup:

Geez my intertubez is nuts today! For some reason it always double posts!

Immaculate work Bart, and it looks like it performs well to boot. BTW, welcome to OCA, hope to see you around more.

beautiful build bart, can't wait to see what it does strapped to a cpu.

Nice build their Bart, are you looking to take orders as well??? Would it be possible for you to provide a quote for this or some other similar build???

4 fans on a single stage seems like a lot. Is it extra quiet.. or ultra low power or something?

I'd rather have those 4 fans with more contained static pressure than a huge Cessna prop blowing stuff off my desk lol.

rofl, ditto

What condensor are you using ?



what temp is the compressor running at ?

Thx everyone :cool3:

Fans originally are 12V 0.8A (kinda strong ;) ), but they're running at 10V 0.5A. Not so quiet, but rotary is still louder. Condenser is about 1kw, I don't know for sure. Compressor is running at 80-90C, I haven't measured exactly, but less than 100C for sure.

wow that looks brutally strong :D
