Teybers Evap

[[XC] 2long4u]

Big bucks in the background.
Looking very nice.

[teyber]

thanks guys! i made an sli pair of evaps today also. i like them much

sorry for the junk on my desk... just snapped a pic lol

[philbrown23]

what? lol what statement

this one, lol

finally my copper came in mail! its a impressive hunk of metal...

[teyber]

haha yeah its a pretty darn big bar... i payed way to much for it too. too bad jinu gave me a different source 5 days after i got this lol. o well :|

more pics of the 3 evaps i made today-



Thats how the sleeve goes on... hard to explain the mounting i have in mind but it should work perfectly for what im doing


If you can see how smooth inbetween the steps are, you can see a perfect reflection. i bet sandblasting will really help


SLI gpu evaps


all three from today...

I think next revision will have an extra step on the cpu evap.

looks really great. Lets hope it will work as good too

Now to thin down those steps, add a spot for a snap ring, and a braze fill area, and hop me a PM

btw andrew: luckily i got the x3 it takes up maybe 2-3 inches which i don't really need while i use the table... btw i was talking with josh(admin from ozcw) about him gettin a x2... omfg! they are so expensive over there! my x3 is maybe 100-200 pounds more then you guys pay for x2 :O

I didn't realise that, shame the X3 is a bit too heavy to ship over from there.

Going to make my own CNC Mill anyway, probably more expensive in the long run but way cooler and 5Axis - Can use a slitting saw horizontally for cutting bar stock to length.

Nice new evap design, would probably make it easier to braze if the cover had something to "sit" on.

hey!

thin down the steps? do you mean the area in between where i cut? the copper part(ridge) is only 1.5 mm, and the space between is only 1/16". the base is very thin, after talking to a couple people who recommended it for core temps. base is about 2.5mm.

Btw... there is those things the sleeve barely fits over the evap... it fits snug. the sleeve is about 1/16" shorter on each side then the evap. You braze the bottum, then flip and braze the top. due to the top being shorter, i test-fit a snapring and it works perfectly the snap ring goes over what you brazed. but in future ill mill out a little recession on the top of the evap for easier snap ring...

andrew: yikes! great luck to you man. 5 axis cnc is very expensive. best of luck to you!

[n00b 0f l337]

Yep inbetween cut to make em taller. Does look like a bit of a pain to braze, but we'll see. Mind PM'ing me the normal details I ask for?

man something unpractical but really nice, would be a horizontal/vertical milling machine, with r8 threads in both but could fit a faceplate on the horizontal one and use it as a lathe

Nah, major change of plan. Going to go for an X3 sized mill (But with more mass and rigidity.) and convert it to CNC. Mind I do have all the electronics for 5 axises. Rotary table on rotary table ? Could always put a right-angled gearbox on the spindle if I want a horizontal spindle.

Done any more evap work ? :o

not saying you to do more just it would be a fun project when i have a house to my own and a decent salary(and tear down a couple walls for a huge shop)

what mill is it?

a heads up, the dyna-myte 2400 would be a perfect mill for doing enclosures and evaps, and they go quite cheap for a full cnc solution.

[yngndrw]

Probably the XJ20, it's about the same size as the X3 but more rigid, more powerfull and (More importantly ) quite a bit cheaper.

Reason why the home made CNC is scrapped - I want to do some high speed machining, which requires rigidity. These mills are much more rigid than anything I could make. I just need to bolt on a high speed spindle and I'm set. At 138KG it's about on my limit as I've got to carry it up stairs, otherwise I would get the bigger XJ25.

Those dyna-myte 2400's are far too expensive for me. :P

[teyber]

next version of stepper evaps-

[yngndrw]

Aren't you going to talk us through the changes and reasons behind them ?

[one_servant]

Aren't you going to talk us through the changes and reasons behind them ?

Indeed, I look forward to reading those.

Good looking new design though. Excellent geometry.

[teyber]

Aren't you going to talk us through the changes and reasons behind them ?

Almost all of the changes are in the base, plus an additional step. Its VERY small less then .8". The base is too thick for my liking but its thinner then the other designs. i want the base to be less then .1" thick (2-3mm). its about 1.5" or so thick. I wanted a snap ring in the base for easy mounting, and a braze ring.

Lots of other changes- and i may add something for my personal use but imma keep that secret for now.

Lots of changes in mounting- ill post that when its done being drawn. Still playing with some additional ideas im drawing and throwing away, et cetera.

You might consider injection in the top and a hole to suction at the bottom. This way you have the refrigerant flowing through the core, which might get you a little better cooling and also you would not have to put the injection line through all of the layers.

Just my 2 cents.

Philipp

BTW: Nice evaps

[teyber]

i appreciate the advice!

The reason i have it like so is i *ASSUMED* and after talking with somebody from another forum who has tested various evaps, that having the liquid from the cap tube coming closest to the core gives a bit better core temps... No hard facts though here.

also- fixed a couple "oops" in the evap and posting a picture of the mounting kit... keep in mind this won't happen till my mill retrofit is completed.



sorry for no rendering- kerkythea is acting really weird.

Nice and what I've been wanting, Tey we have to talk now that I'm back.

[sjg0]

Post pics of your mill setup!

[teyber]

sure thing mate, im at my dads house ATM though so ill try to get you those pics 2maro.

[teyber]

i made a video but i ran out of battery mid-way through filming and can't find charger. sweet






The inner lip pushes down on a snapring on a evap. This is just a test, materials and thicknesses, et cetera will most likely be changed. (i.e- the top mount is not suitable for a mounting... i just had it around just had to bore a hole in it)

the first prototypes of these will bel made with UHMWPE (is that it? might have to many letters) for the round part and PVC for the hold down part. will problalby switch to 3/8" later but this should work fine.

regards

[teyber]

Next 10 or so mounts i am thining will be this combination. i love prototyping by far the most fun part of the process. The pvc is VERy strong, however can an engineer tell me if its toxic to breath its fumes?

This is a pretty time efficient combination on the mountings (as compared to my earlier ones... the large 1 peice enclosures- NOT the ones from the first post) and SOMEWHAT cost efficient. (definately not like polyethylene lol ).

Im excited about this. no holes drilled in this yet sorry.

It isn't bad to breath them as long as you don't do it for a living.
