Just to show everyone that I'm not all talk, I am building a chiller evaporator. My goal is to shrink it to the size of a plate heat exchanger. I have a stack of evaps in my basement, each one progressively smaller than the last.
I am getting close. :D

what do yuou mean by a chiller evap?
i dont really get it :o
wouldn't that be the same as a waterblock with chilled liquid inside?

It's where the refrigerant chills the water (antifreeze actually).

wouldn't it be more efficient jus tto have the refrigerant cool the CPU itself?
Charles Wirth
03-25-2004, 10:23 PM
Depends, with a chiller like the one he is planning would not require a special evap and mounting. expansion valve on a shell and tube works awesome as a water chiller. custom brazed plate heat exchangers should work even better.
Gary can your heat exchangers handle the high GPH?

Gary Lloyd
03-26-2004, 02:24 AM

Yes and no. Compared to direct die (evap on CPU), you lose a few degrees in the extra heat exchange, but you gain flexibility. It is much easier to cool multiple blocks with a chiller. You can easily disconnect from a chiller to upgrade blocks, hoses, pump, etc., and for those who already have a water cooled system, it is relatively easy to add a chiller and insulation.
Gary can your heat exchangers handle the high GPH?
High GPH should be no problem at all.
we need a how - to for tuning these chiller from ya gary :D when u get there please explain and pics! ;) :) can u borrow a cam? ur a phase change man and they are mandatory!:cool:
Gary Lloyd
03-26-2004, 04:18 AM
The pics won't do you much good, anyway. What you will see is a flat box, with 4 tubes coming out of it. I'm not telling what is inside the box. :D
At this point it is down to 5" x 10" x 1", and shrinking. It is all copper and all brazed.

03-26-2004, 04:19 AM
So gary are u going to use a TEV or a Cap tube
and good luck making a super cold chiller:up:
Gary Lloyd
03-26-2004, 04:21 AM
It can be used with either.
At this point, I'm not planning to build chillers, although that may be coming in the future. I'm just building evaps, kind of like what Baker has done for direct die evaps. I'll let others build the chillers. :D
Flat plate brazed evaps go for about $300. I'll try to cut that in half.
Im sure ur temps are going to be way nice! my temps with a 107w load went to -15c! thats alot of heat ya know. This is with good insulation, anything below ambient is insulated. It probly woulda gone down to -10c. Cant wait to do this prescott at high volts and mhz to see POSITIVE temps lol:D

Horizontal. For example, in a window A/C it could take the place of the air evaporator.
Gary Lloyd
03-27-2004, 10:57 AM
Okay, the latest version is 5" x 5" x 1.25". I had to build some custom tools to make it that small. But still no pics. :D

So two compressors and three of these very compact heat exchangers would give you -80C liquid?:D
Regards
John.
i kinda see what your saying, just having the refrigerant chill the liquid
you basically have a waterblock, which si inside the evaporator
teh waterblock is hooked up to a pump and res, minus the heatercore and the usual evap for liquid chilling
you pump the refrigerant around the block, chilling the liquid
hmmm
-80C liquid O_O!
Gary Lloyd
03-28-2004, 03:35 AM
So two compressors and three of these very compact heat exchangers would give you -80C liquid?
The outer jacket is designed for low pressure coolant. I wouldn't trust it for high pressure refrigerant. This can be strengthened, but it would add considerably to the cost. Yes, this is doable, but not with the current jacket.
How cold do you expect your chiller to go, and will you be using a means of regulating it?
I have to say I think your avatar of your granddaughter is in good taste, she looks precious. It is defiantly one of the better ones on the forum.
Gary Lloyd
03-29-2004, 08:31 AM
How cold a chiller gets depends on the refrigerant used, the cap tube, and the compressor, not the evaporator. At this point I am just building compact chiller evaps, not chillers... yet.
That said, I have put together a window A/C chiller to test my evaps with. It got down to -51C last night (no load). :D

could you get those kind of temps on a regular A/C by letting some of the charge out? i get down to like -39c but under load and stuff it got down to -14c :eek: my load temp sucks
He has recharged it with r404a.
Gary Lloyd
03-30-2004, 05:36 AM
Actually R408A, which is similar to R404A. :D
Yea sorry lol. Would you notice a difference between the two, a few degrees?

Your cap tube is tuned for an A/C, performing it's best at just above freezing temp. Adjusting the charge would help, but the cap tube is the key.
Gary Lloyd
03-30-2004, 05:47 AM
Yea sorry lol. Would you notice a difference between the two, a few degrees?
More like 1-2C difference. The big advantage to R408A is that it doesn't require an oil change.

So do i need to pinch it? or both? or isnt pinching it just the same effect as letting some out?
Gary Lloyd
03-30-2004, 07:58 AM
I have never pinched a cap tube, although in theory it should work if done very carefully. The right way is to replace the cap tube, not pinch it. And no, pinching is not the same effect as adjusting the charge.
So is r408a the best gas you can get easily for a chiller? Thanks for the infoe gary, if you start to sell you teeny weeny evaps I will prob get on and have an excuse to change the gas and cap tube at the same time. There again that is not going to be easy:(

well, if I could hold -35C under load i would be happy. What do you think would be the best way to do this? Im leaning towards the charge myself but im far from an expert. thanks :)
Gary Lloyd
03-30-2004, 09:11 AM
There are several R502 substitutes on the market. All perform similarly. R408A will eventually be phased out (by 2020), because it contains R22. It is my understanding that R408A is no longer available in Europe. Eventually, there will only be R404A and R507, both requiring POE oil.
Yeah, I belive that r22 has been banned from being traded within Europe:mad:. Although I'm not sure about from the US:) I dont know. So if r408a is a substitute of r502, why do people not just get r502? is it expensive or something. I should have some by 2020 anyway so that should not matter but you know the UK they probably have phased it out already:confused:
Gary Lloyd
03-30-2004, 10:06 AM
R502 is right up near the top of the environmental hit list, and is already banned.

That big box in front contains the evaporator/reservoir, covered with dense foam insulation. Have I mentioned that insulation is our friend? :D
Note my TECH Method "key" logo in the lower right corner.
On top is the fill tube.
Those are 1/2" hose fittings on the front. Right is water out. Left is water in.

Sweet!!
One question. How loud does that get?
Gary Lloyd
03-31-2004, 01:28 PM
It has a big fan on it. Could be replaced with a muffin fan to make it quieter, or a fan control could be used. The compressor isn't loud at all.
As an added bonus, it has all of the hardware for mounting it in your window, putting the noisemakers outside, with several inches of dense foam insulation in between.
runmc
03-31-2004, 02:29 PM
Nice job Gary!! It looks like it right off the assembly line. That will make a great toy for some lucky guy or gal.
Have you had a chance to try it out yet?? What does the reservoir hold, about 2 gallons??;)
Gary Lloyd
03-31-2004, 03:53 PM
The reservoir holds one gallon. Most of what you see there is high density insulation.
It hasn't been tested under a real load yet, since I don't have a water cooled computer, but I'm betting it will match a prommie, and cool all of the components, not just the CPU. It has been tuned for max performance at about 250 watts heat load.
gary, i dont understand how this differs from a regular chiller
it loosk like you just stuck the evaporator inside a resevoir
or did you make a new evaporator? O_O
sorry for questions ahah

Yes and no. The original evap has been modified, added to, and given a full copper jacket. The mods worked out better than I expected. :D
why would you need a full copper jacket?
is that basically the resevoir?
zakelwe
03-31-2004, 10:19 PM
That looks very very good Gary. You are right about it having one advantage over phase change, with this you can have the gpu and cpu cooled with two water blocks in series.
It's a shame you do not live over the road as I have twin waterblocks in series :) maybe there is someone on the forum who lives driveable with similar setup ?
I'd be interested to know how flow rate alters cooling with this setup. Normally you want a pretty big gph for water, but in conjunction with something chilling the "warm" returning liquid what is the minimum time needed in the actual chiller reservoir the liquid needs to stay in to be chilled down again ?
If you could adjust the flow rate on the pump ( or pumps in series ) you could measure temps on the fly at cpu / gpu to fine tune.

150w for cpu and 100w for video card if in series. That's certainly a lot cheaper than two phase change systems.

It is against the rules to mention price in this forum. I have quoted the price in the classified ad section.

Yes. Since I took the pic, I mounted a black plastic disk on top of it for a better grip. Makes it easy to fill without having to remove the cover.

That chiller has been sold to jamaljaco, and is on its way to Oregon. Jamal has promised to thoroughly test it for us. :D
In the meantime, I have started building a second chiller. This one will have a smaller evap/res, which will allow me to keep the control panel. The control panel has a switch and a thermostat.
The switch has 5 settings, OFF, LOW COOL, HIGH COOL, LOW FAN, and HIGH FAN. All will be wired together, so that it is either OFF in the OFF setting, or ON in any other setting.
The thermostat will become a fan control, with its sensor mounted on the liquid line. This will bring the fan on only when needed. Another big plus when mounting the unit in the window.

04-07-2004, 08:21 AM
Building the evap/res is the most difficult and expensive part. It is completely copper and all brazed.
I am progressively miniaturizing the evap/res assemblies and will eventually reach a point where the efficiency is unacceptable. Thus far the evaps tested are very efficient, but I have some much smaller designs in the works. When I find the optimum size, I will market the evap/res assemblies for those who want to build their own chillers.

WindowChiller #2 is still looking for a good home.
I'm going to have fun this summer with the window advantage thing. Whenever someone says their phase-chage system warms up their computer room, I will say "Stick it in the window, and put the heat outside". Noisy? "Stick it in the window, and put the noise outside." Want a performance boost on a cool evening? "Stick it in a window, and let mother nature cool your condenser." :D

i could only wish, i need a system first and of course some water cooling too, or maybe i could build around the chiller... i would owe my parents for watercooling and a chiller... they are paying for my system... the skt 754's chipsets need to hurry up...
oh and i dont know much about water cooling, whats good and were to buy.. i would wanna cool cpu and the gpu of course..

They're getting so small you will be able to stick Walkman on the end of the name you come up with .
I can see a GLD Walkman 9200 Pro chilling my laptop on the Heathrow to JFK redeye :)

I got a GF3 ti 200 that can be sent to Gary, it has not heatsink on and has the old style chip type ( non flip chips ) so has a lot of surface area for attachment.
I would like to see Gary do a cpu and gpu in series, hence the video card.
It does 250 on air and 270 cooled with water and pelt ( estimate is -20C for that ) , so if Gary slaps -40 and below on it it would be interesting.
Either Gary or RUNMC PM me if you want it
Regards

Update:
My first WindowChiller was purchased by Jamaljaco, and he is currently testing it on his system.
In all honesty, I should point out that Jamal's chiller is not performing as well as my calculations indicated it should. Lacking load testing gear, I guestimated that it would maintain -40C under full load, and it is in fact maintaining -31C under full load. Nonetheless he is happy with the performance. I am not. As soon as I figure out what is needed, I will have him ship it back for modifications.
It is not my intention to mislead anyone or to engage in false advertising.

On the bright side, he tells me that despite the large fan it is very quiet in operation, and totally silent when mounted in his window. :D

I'm sure it's a lot quieter than what he had to listen to before. Gary, next time you talk to Jamaljaco tell him OCme said hi. He was my friend and the first one to make me feel welcome here @ XS.

gary do u think u could sell just ur super efficent evap/res for the DIYers?
At any time, I am willing to sell my latest tested evap/res. I will not sell the ones that have not yet been tested. All of them have similar efficiencies thus far. It is just the physical size that I am shrinking. This means they hold less coolant, which gives them a faster pulldown time.
My latest tested design, insulation and all, fits easily into the spot where the evaporator coil was in these small window A/C's, with plenty of room to spare. If you are interested, PM me.
By nature, I am never fully satisfied with my work, and could keep re-designing and testing forever. At some point, I need to say "Good enough", and bring a product to market.
By nature, I belong in a laboratory or an insane asylum, I am never sure which... LOL

gary, that's one sweet chiller... i wish i got the money to get one...
i got some suggestions that might make it better... how about instead of 1/2" barbed connection, how about a brass plumbing valves w/ barbed ends (like ones at www.mcmaster.com, page 419 or part # 4630k21, so it can be more portable) or 3/4" or 1" male or female npt connections, so that way people can use higher flow rate sized pumps...
thx for reading... take care...

Lucid, I tried to respond to your PM before, and it said you were not set up to accept PM's. I sent you another PM, and it seemed to go through this time. Did you receive it?

Sounds good, getting back into the trade.
Gary, this latest chiller certainly has captured my interest... please post pics of your progress

I got a digicam. Went through all sorts of crap to get it working (long story). Finally got it working and then discovered that it has a usb connection, which my dinosaur computer doesn't have. Pics will have to wait until the new rig is up and running.
I am now testing chiller #3. It does -41C @ 100 watts heat load, and -36C @ 250 watts heat load. :D

Sounds good, now to await from pics. Do you use an actual captube or some other device?
Gary Lloyd

I use a cap tube. I have toyed with the idea of using a TXV, but this would add substantially to the cost. I want to keep the price low so that I can sell these.
