New evaporator Maze GT1 by tiborrr

Idea originated from the early models of Gosmeyer, Eleven, ... and all the other brave & innovative guys on the XS forums. I got the idea while browsing through the XS evap gallery therefor my product is nothing really new.

Although not finished yet (they are 40mm wide; final product will be 17mm high including the top, it will have 8mm suction return line), the top still lacks the proper holes for suction line & capilarity tube, they need to be cut to proper lenght. Also the channel for the DIN471 retaining ring need to be milled. But these are all minor jobs. Oh yes, forgot to mention - it has a centre suction, capilarity tube enters the evap in the chamber next to the centre suction chamber.

Those are two prototypes i have at the moment.

Nice job but I think you'll find that thicker channels will be really beneficial. Looks like a good 11-evap though :)

Very nice. Do you make them just for you or do you want to sell them?

Thanks guys :yepp:

I made two, one has to replace original evaporator on the Moonman's Mach I (the suction line was ruptured so i was thinking we could swap the evap aswell), the other one i planed for a upcoming R404a/R1150a 2xNL11F cascade (still some parts missing, ran out of money...).

@Moc: If the interest will be high enough, i just as might start selling them :)

I'm in the market for some GPU evaps. Quality work there mate, keep it up.

Moc & one_servant: Will notify you both as the new series goes into CNC shop next week.

Thanks for nice response! :yepp:

Perfect. Thank you :) .
But nevertheless I would be interested to know your hold-down plans :) .

Here's the 3D CAD model of the evaporator plastic housing / enclosure with exchangable retention clips that just went into prototype production. I should have it in my hand in a day or two. The socket retention clips will be held by a giant 60mm retention ring (DIN 471) while the rounded enclosure will be fixed permanently to the evaporator by a poliurethane foam or some other, low W/mK foamy adhesive substance.

This looks very promising! Why are you using German CAD Software in Slovenia? :confused:

Thank you PhilippF!
Why? I'm just used to german version, it's multilingual, but i had instruction manual in german language :D

sweet

Today I was playing with Tiborrr's evaporators. First I cut them with saw on the right size and then use lathe to flatten the base. Final act was polishing the base.

Design of evaporator is really nice and big plus is that it can be used for CPU and GPU cooling solution. Tiborrr and I already work on enclosures for both (cpu & gpu), first prototypes will be make in next days.

First prototype of CPU enclosure for GT1 evap. Enclosure made on lathe (2h+:D) and retention lasercut. Insulation and evap holder is missing.

As already said, you definitively need thicker channels. In addition I would suggest a center pole. AFAIK you need to change the evaporator so there is liquid refrigerant above the core. So let the capillary tube enter in the center or change the design so the center is always flooded. Are you going to braze the capillary tube simply in such a way into the evaporator? Take a snatch of 4mm or 6mm copper tube. Way more easier replacing the capillary tube than heating up the evaporator again.

This evap is for Tiborrr and he want such position of enter for suction and capilary tube ;)

beautiful! i don't think cap tube entering on inside will make a difference of a a couple degrees, but i really recomend 1/8" walls...

regards

Nice work teyber :)
Looks hard work though

o also, how is the evap being held in the enclosure? not seeing it... No snap ring, only 1 other way i could think of but then it would sit too deep in the enclosure... maybe foam, like on vapochills?

regards

TNX for nice comments :)

@Teyber, nope, I lathed extra plastic seat for it (similar to my Fi60 evap version).

- render picture (I didn't pictured whole enclosure jet, I'll when 2nd fill be finished):

Evap holder needs to be cut (so it can be installed/removed from evap). Here're little pics how it'll look like on mb:

This is probaby going to be a retail version of the evaporator & it's enclosure, suitable for many popular sockets (S462, S478, S604, S939, AM2/AM2+, LGA775/771). If all goes well (bank loan) they should go into production on monday.

http://shrani.si/t/3N/On/3iakXiPE/promoretail2.jpg http://shrani.si/t/N/8n/3zis28J5/promoretail.jpg

Enclosure and seat made of POM acetal or equivalent, backplate and multi-socket retention clip will be made of steel. Mounting holes are designed for M4 screws (therefor 4.6mm diameter as per standard).

New one :)

Here's a unit i'm repairing (actually my first direct-die single stage cooling unit). This will be the first unit that will incorporate the Maze GT1 evaporator. This is Moonman's Mach I, that was originally regassed & retuned by cold_ice ~ four years ago. It was eventually ruined (broken suction line) by a so-called friend of mine to whom the unit was borrowed. Now it was up to me to repair this thinge.

I recieved another Mach I condenser from my good buddy Dimas for a bargain price of 10€ and also bought a new very flexible stainless steel suction line with 8mm copper endings for about 40€ (IMHO really expensive!), some 12-13 (38mm) armaflex pipe insulation. I even recieved a black nylon sleeve for the suction line from LittleDevil for free (thank you, Ales).

The second condenser acts as a desuperheater -> discharge -> back condenser -> front condenser -> drier/filter -> metering device

Had to bought some proper tools aswell - pipe cutter & flaring tool (around ~ 60€ alltogether).

If i'll have some spare time left this weekend, i'll braze the evaporator and few joints that are not connected yet (yes, all the compressors ports are at least hermeticaly taped down)

http://shrani.si/f/3Y/z4/3mBeudix/dsc0151.jpg

Please... make holes for the pipes which go to the first condensor!
If you have the money, buy a pipe bender!

I made a similar assembly in a Mach II to Chiller conversion. My next SS will be also with a Mach condensor in the back :)

Greets!

Holes can be done, but onfortunatelly i cannot invest another 35€ this month into a pipe bender. Will buy it next month ;)

Looking good, Moc! And thanks for the support :yepp:!

After months of no spare time to spend on the Mach restoration, the unit is now finally done:

http://shrani.si/t/2l/on/4HrhMUU5/dsc0558.jpg

Sloppy me - burned through copper pipe due to thermal load of acetlyene/O2 torch flame:

Brazed evap Maze GT1:
http://shrani.si/t/2n/wY/1qen0lCa/dsc0560.jpg http://shrani.si/t/32/ut/3Ung2FRw/dsc0561.jpg

System running while charging. The manifold is a bit f$$ked up, so the low side port is attached to high side manifold's port:
http://shrani.si/t/3V/6k/4JduHQFr/dsc0562.jpg http://shrani.si/t/X/F5/37hCc9JW/dsc0564.jpg http://shrani.si/t/2F/Mu/qRcVkJ7/dsc0565.jpg http://shrani.si/t//Yo/3rllpvfp/dsc0567.jpg

-62°C but unstable, -72°C was achieved for a second or two before the compressor shut down :)
http://shrani.si/t/2e/oi/2kHH47OZ/dsc0568.jpg

The unit is faily overcharged, but the pull down is mega fast - about 20-25 seconds from +20°C to -40°C, perhaps due to evaporators really low mass. The report on the temperatures will probably be tommorrow because i still have to find the optimal charge for it.

You really should purge the low side- did you purge the evap?

also- do you make the evaps yourself? do you have any pics of the milling machine its on?

good work btw. im guessing part of your manifold is leaking? i hear ya that sucks...

good work :)

The low side and the evap weren't purged since i did not have any nitrogen, next time i will certainly purge. The evap was made on the CNC machine, i just made the MasterCAM program with some help of the CNC operator out of my 3D CAD model i drawn in OneSpace Designer.

Thank you, teyber :yepp:

First temperatures - IMHO still a bit overcharged (cap 0.8mm @ 2m):
http://shrani.si/t/41/H0/4hSra1uI/dsc0572.jpg

What type of mill is it? is it yours or do you have access?


regards

edit- the braze job is awsome!

No, it's the 400.000€ CNC machine owned by a local company that produces parts for automotive industry and i happen to know the owner :) It's not for free, but it's not that expensive too. Thanks for the compliments, it was so easy on the oxy/acetylene and i haven't had much practice with brazing before (that's why you can see some excess braze on the discharge line).

Thumbs up to LittleDevil who assisted me with the wiring of the NL11F (it turned out the starting device - the winding was faulty) over the telephone :up:

After some refrigerant release:
http://shrani.si/t/b/60/4rofJzz9/dsc0579.jpg

Edit: -51.5°C. Now i'm really off to bed :lol:

Insulated with pour foam posing for a shot without thermal load:
http://shrani.si/t/2w/go/1sJPrkDw/dsc0580.jpg http://shrani.si/t/4/9N/1Nfhghim/dsc0583.jpg

Looks like this type of foam insulation is good enough for ~ -50°C operation, no humidity on the outer shell spotted. It's thermal conductivity is - as specifications state - 0.039W/mK (armaflex 0.036W/mK).

P4 631 @ 5.36GHz, 1.76V:
Power rating: cca. 231W calculated theoretically -> let's take that with the grain of salt, ergo * 0.9 = ~ 210W thermal load

My other SS
Chilly1 spiral clone evaporator
R404a
Electrolux MP12FB 3/8HP
CPU Temp: -27 ~ -27.5°C CPU
Evap Temp: -44.4 ~ -44.6°C

Mach I - restorated & modded
Tiborrr's Maze GT1 evap

Danfoss NL11F 1/3HP
CPU Temp: -33.5° ~ -33°C

I'm friggin' satisfied! :yepp:

Nice job!

Thank you, it means a lot coming from such an established phase change builder :up:

Heh I wish I could get a beautiful mount like that around here, I love the look.
Plus you could easily add a donut of foam around that if more insulation is needed.

http://shrani.si/t/1J/SV/M8ruZOi/img0093.jpg

new retentions :D

I hope you don't mind mate, but I like the metal mounts, might have to work with that. The muff I've always wanted though the other way, consistent quality pour foam is rather hard to do, thus a snap ring and foam donuts works for me.

I absolutely love them:shocked:

what gauge is that?!? as long as those don't flex those should sell in a heartbeat!!!!

it's impossible to flex them, 3mm steel and galvanized. Version for all sockets has inside Fi63 and LGA775 has Fi66. In next order i'll keep just one Fi (i need to decide which one is more practical for enclosures -soon some Fi50 evaps on cnc).

3mm hahaha, okay that explains alot ;) Those shouldn't bend then. And the looks is so nice.

I see some thread hijacking going on. Anyway, here's a model of a 9800GX2 evaporator made out of two Maze GT1 evaporators (one is normal, the other one is mirrored version so the channels line up), lowered by few milimetres.

http://shrani.si/t/2x/RW/cM6SuBP/promo1.jpg

No retention clip need, only a plastic tube filled with pour foam will complete the insulation as well as two backplates.

This was the main reason why i ordered retail series of evaporators in both form, mirrored and normal :up:

My new babies are here - the Maze GT1 EE (extreme edition) :up::

Woa. Those look beautiful. Any plans to sell?

nice!

glad to see you added a snap ring slot. really makes mounting a breeze

I'd also like to know if you're willing to make more custom units.

Hey that looks pretty tedious! I mean if you got that mounted you would still need to insulate, not to mention somehow cool the memry. What I was thinking of looking into is buying an all-copper GX2 waterbloack, and brazing a suction and liquid line to it. Its probobly not going to be the best, as it was designed for water, but it should be pretty easy to install and mount.

But please keep me updeted! I want to know how this goes!
