phase change project

robmac · 18 Apr 2006 at 23:46

just thought i would share my latest project iam building for a friend

its a small 1/5 hp r600 compressor
stainless braided flex line-600mm long
stepper evaporator made by me

will be using r290 for gas as i have had good results with this and my evaps.

added a little desuperheat coil as the condensor is quite small.

hope you like it.

had her up and running yet? - looks like a nice lil set up - how much she cost you to build (unless you dont wanna mention)

robmac · 18 Apr 2006 at 23:53

already built one for myself with same setup and getting -55.c evap-idle
-35.c-cpu-idle.
-46.c-evap-full load and -10.c-cpu-full load.
not going to talk pricing as i make these for people.
not as expensive as you might think though.
keep the cost down by making my own evaps and flex lines.
cpu is xp3000-754-2gig @3gig [email protected] volts.

xp3000 754? - either amd64 3000+ or 754 or skt a athlon xp3000+ (im impressed if its the latter, they do kick out some heat with volts)

Nice mate, looks like a good bit of work. Any pics of the one on your rig?

Looking good.

Do you have any detailed pictures of the evap and its design (internals etc)?

Looks cool (sorry for the bad pun), wish i could make something like this. I work as a marine recruitment officer so i might put "make a phase cooler for a computer" in my interview process for reefer techs

Well I havent really looked at it as not something im planning but linky (vr zone) seem to have a rather good guide there. It's for a dual head system but it has links to the bits you need to know to get you that far.

It's good

It's just that it's not quite as impressive as if you'd got a Newcastle 3000+ to 3GHz

Nice setup though

robmac, how easily could you replace my machII refridgerant with r507 ?

i've got R134a in there atm

robmac · 19 Apr 2006 at 23:15

only got access to some r404a, sorry. but that would be a lot better than 134a.
