Custom 62mm TEC Water block - Page 17  

post #161 of 680
Well yeah but I'd still be interested to see how it works when it is properly laid out. Pins have the capacity to add more surface area but also increase the pressure drop much more.

Nearly every single top contender commercial block I see do a variant of something like this




Have you explored this direction? With some very small endmills or slitting saws, no doubt you can mill it.

I have gotten my hands on Solidworks......but am still trying to figure out how to do anything with it. Not nearly as easy to pick-up on as Sketchup......and even sketchup confuses me lol

Well the only problem with a block like that is that you'd need to make the slots 62mm long and 62mm tall or else it wouldn't work. The entire length and width of a TEC block needs to be cooled perfectly equally (or as close as possible).

if you clicked on the link that i posted you'll see the text flow that stats Herc say it's not going to work. Then me saying i tested it "I tired a channel like this"







From what i can understand that would end up making the channel very wide or the fins very wide but you probably should sketch it in paint so i know i understand what you mean. And please do sketch it up

Solid works definitely deals with turbulence.. i could post a pic of the turbulence density pic.

no simulation software is perfect but it'll be close enough to get you a good idea of whats happening
very well, here's the sketch.

a little better than the last if i say so myself.

Well, it is a custom made block.......

And I don't think you'll get much more even and total coverage then evenly spaced indentical fins. The only differences will be at inlet and outlet....which is true for any design, but with this it will be more even since you spread the inlet and outlet an entire 62mm

yes thats quite a good pic ..

Im guessing we take the right one then add the ZZ to it?

cos currently the left one is better because it has the higher velocity . But it's to restrictive to add the ZZ to

If that's the idea then i could see that helping / worth testing
post #167 of 680
yeah, that's it. if zigzagging on the left is too restrictive, the right should compensate for that, but hopefully not too much.

yeah, i think swiftech style fins would work decently over a surface of 62mm wide and x*62mm long for x TECs. with water flowing lengthwise, evenly over the pin matrix.

Interesting design ... in it's current lay out it's definitely not distributing the flow = these that big cut out which is ensuring the flow Wont be = distributed..

http://www.overclock.net/attachment....1&d=1248654169

I could easy enough fill that back in though. still the distribution wouldn't be perfect .. but it maybe good enough ... obviously this it more complicated and required an extra layer it the cover that's not shown

unfortunately i've just realized that your proposed design means each channel will be a different length which will mean an uneven flow distribution

i dont think that should hurt much... especially if they're only 1-3mm channels/fins.
