1st Post and 1st WB design. Any comments?
 

Hi,
want to move into the watercooling scene, but want to make my own waterblock.

I have looked round the forum and its a real help.

I have come up with this:
http://img201.echo.cx/img201/959/wb3jpeg1se.th.jpg

There are 17 veins, each at 0.5mm width, and then another 0.5mm fin between the next vein. Its designed for 3 barbs, all 1/2 inch size.

The block is 6mm deep, with the veins being 4mm deep

Any tips i can have to make this better (only got a simple cnc machine so not complex curvs :P)

Make the block 3.5mm deep, and the veins 2.5mm deep, to respect cathar's LRWW measures.

Please tell me where can I find more information about this cathar´s LRWW measures?
Thanks.

He's refering to Cathar's Little River White Water waterblock. This site has a review of it, and you can find discussion in the main part of the liquid cooling forum.

Sorry, the double post.

anonymus6 : Interresting image! Did you made it? With which program?

I not made it so far. I hope else testing whit a program. The program: fluent 3d. I have go to one program: (fluent) gambit. Then can i testing.

The block design idea to come a nexxxos hp pro block:
http://www.techangel.co.uk/reviews/n...hppro/top2.jpg

The cutter is only 3mm height! The coldplate is 1.5mm.

Now i don't no, the spines space. The space, i think 0.3-0.6mm. The spines 0.8-1mm.

At last I have the gambit program. But not easy. So far I can't making one cube, in the modeller program. Not to be near, 3dsmax, or oother CAD programs. :(

very interesting work done there anonymus6, keep up the good job and go 3D... then you can do some real simulation man! well done :)

btw, where can we download this program from? :D

Cheers,
B

Pins superior to fins? I think so. I remember JD being of the same opinion. The MCW6000 series is a center inelt pin block that performs exceptionally well. What you need is a practical viewpoint. Pines might be too difficult for you to cut, and they might not improve performance enough to make a difference. If your flow is low, less than .5gpm, I'd say that pins would improve performance substantially. If your flow is above 1gpm I don't think the performance increase would be worth it. Look at the flow vs. CW curves of the WW and the MCW6000 to aid your decision. This will tell you if pins are worth the effort.

To the pros: don't you have to worry about Laminar flow if you get your pins spacing too narrow and/or too deep/shallow?

Speaking of pins and DIY blocks I am working on a couple blocks that fit that description.

Pic of a work in progress attached.

maxSaleen: laminar flow is something to consider. You want enough gap to cause the water to stir like in the demonstration pic posted above by anonymus6. I am in the process of starting a series of experiments on the pin grid block design.

yes, but you're forgetting that the simulation anonymus6 did was with the flow passing from right to left on the X axis ;)... how about fins with the water being sprayed above the fins?! (like the LRWW)... that would be good scene to be tested on CFD but needs to be in 3D shape etc.

I prefer to test with real blocks instead of models. If you took the white water and made pins with the fins the performance would not be a lot better and maybe worst. Pins are better with thicker bases IMO. Lots to learn yet though. Only been doing it for 4-5 years off and on. Not a lot of thorough testing done yet.

yeh sure, i was just speaking generally... 3D helps a lot, specially if proper CFD software is used correctly :)

Definatly cut down on prototypes. Personally making the prototypes is the fun part. :cool: Definatly the way to go for a company though.

what programs are used for simulations? I do 3D art in my spare time, so this could possibly help make things not suck when i finally get around to making some blocks :)

Hy!

My first microchannel:

In a picture the block is very dirty. I apply special oil. Later I come back.

OUCH! Thats some delicate work, impressive!! :eek:

Thanks!

But these block is just ALPHA version. The space: 0.6mm. In a BETA version (next block) I will go under 0.3mm. The consummation (prototype block) is: 0.2mm. ;)
The BETA to brew after 1-2 week. First, I must building my cnc.

I've made no progress with the programs. In our midst the copper is not precious. I made my plans and after I test them.

Very easy and firm way. :)

Looks interesting. Like to see the final version complete and running.

Hy!

New hope! I download the next programs:
- autodesk inventor 10 (in this program draw I the block design) [CAD]
- cosmos floworks 2004 (in this program the flow simulator) [CFD]

I made one microstrukture block in CAD, and I start the simulation. My processor (amd 1800+@2200MHz [t-bred], calculating to five hours and not complite jet! :D
No prolbem, I have time...

Whether can I the CFD program using in my render farm [13GHz cpu capaciti]? Good question, ha? :D

My blocks is 90%. I need tube connectors. I post presently pictures.

The desing is very nasty, but this block's just ALPHA/BETA version.

Shit!
I must stop the simulation. I need this pc (when run the simulation). Grrrr!!! Start the simulation other pc... Over and above the program not supported the net/lan count. I need faster pc...
