Has anyone made there own pahse change cooling system? have looked into this and seems do-able enough, with the right amount of time, just wondered if anyone had attempted this or had any links/thoughts they could share?

Thanks

If you have VAC pumps and access to one of the gases needed.

Oh and the huge expertise needed to tune the unit, and a heatload tester.

compressor/condensor/suction line/capillary tube/Some kind of evap head.

Sounds very easy

I did not say it would be easy, compressors are easy enough to come by, lots of broken fridges in the world! the evap is the main stumbling block, although have found some people that sell them, mostly in the states though, so postage costs add up.

but thanks for your input.
 
best thing to do is pick up a mach 1 / vapo xe and modify it to take a better gas/change condensor and maybe change piping to 10mm etc.

That was you have the evap head already.

Prob get one for £100-150

yea, theres ebay. they pop up forums from time to time. you have access to the MM?


EDIT, think you gotta have like 250 posts.
Theres a trading section on this forum :). people buy and sell stuff.
 
A guy I know built his own one. Total cost of £200-£250, and at the end of it all he could't find that leak. I prefer to let other people do all the hard work for me.

Have a look over at XS. Loads of threads on DIY Phase.
 
The principle of it is simple enough, and there are plenty of guides and tips out there to help you along.

However, the problems as I see them are:

The initial cost of tools is expensive.
Large time investment.
If memory serves, you have to have the relevant qualifications to handle refrigerants.

Other than that, it's something I'd like to try one day. However, these problems (particularly 1 and 3) are the main stumbling blocks as I see them. If you're in a position to try it, then I'd say go for it. :)
 
Depends on the gases, i'm pretty sure you need a license to handle some gases but R134 is easily accessable by anyone.
problem comes with filling the thing as you need to be licensed to do this no matter what gas and if you do it illegally you face a hefty fine and possible jail time especially if you dont buy the recovery gear (~£500) as you'd be venting the gas into the atmosphere which is illegal for everyone.

A lot fridge parts wouldnt accomodate the load that a cpu would give out so if your looking at finding an old scrapped fridge your only really gonna be able to build a GPU cooler.

The building it aspect is easy aslong as you have the tools, knowledge and decent brazing ability. Filling it and tuning it to be something worthwhile is a completely different step though

ok, i build phase change units. make my own evaps on my lathe/milling machine.
i make up my own flex lines etc. the only thing i have to buy in are compressors and condensors.
as for gases you can use r290 without any licence requirements as its just common propane.
any one who needs any info or a unit built or just some help with their project, pm. me.
 
got my 754 3700 running at 3 gig. -35 idle and -15 full load running prime, occt @ 1.75 volts using a 1/5 hp compressor and r290/r404a mix.
evap temps are -48 idle and -38 full load.
