Is this a center inlet, dual-outlet design?

ok so here it is. i changed the way water is going to enter the block. i don't know if there is a name for this but here is the concept. in the block there are 7x7 holes of 2mm each, in the second layer there are 5x5 holes 1.5mm each. the top layer will be smaller in height that the thread of the barb so that the thread of the barb enters in the hole that there is in the second layer round the holes.
there are 2 x 3/8" outlets and 1 x 1/2" inlet. hope that you understand the diagram. btw i am planning that both the second layer and the top will be made out of perspex

I tried this once. http://forums.procooling.com/vbb/sho...&threadid=5476
No good. Holes to close to each other and all it did was drop flow rate. |

jaydee what do you think of this layout, making small holes like the one shown and make 3 x 3 1.5mm each instead of 5, 3mm between each edge??

Two thoughts,
Turbulence caused as water hits each of the drilled holes in the channels does not disapate instantly upon going back into a straight walled section. Thus you could reduce the number of holes drilled with little or no loss of performace due to turbulence. And a reduction of say 1/3 to 1/2 the number of holes drilled would also give you back some fin mass. Would also save time and improve ease of making it. And I would use a impingement slit instead of holes. A slit should give slightly lower head loss than a series of holes of the same total open area due to reduced wall contact. Would also be much easier to cut than a set of very tiny holes, agian saving time. Keep in mind that while this sounds good to me, I havn't tried anything of the sort. This is offered only in a attempt to help add some ideas, not from hands on experiance. Wish I could afford a small mill. |

10q blackeagel, i will reduce the number of holes in the water block later on because tomorrow i have an exam and i need to study. on the top, that what i was thinking of but for now here is the concept of the inpingement.
i could do both, one with holes and the other with slit and see which one is the best i also changes the input to 5/8". i know that it is too big but it is enough to fit 3 holes for the inpingement. here is the 2nd layer. any comments

BlackEagle summed it up well. I also agree with his slit cut idea as that is what Cathar uses on the White Water BUT I have one mod to that. Instead of just one strait slit, make a + slit. That way water will get into all the channels and an extra bit of flow rate directed dead center. Just a thought I have been playing with myself. Thats what I plan to use on my REV 2.0 when I get around to it.

One thing: if you're going to limit the matrix of the pin holes to 5x5 or 3x3, you're not shooting any water in the outer channels, which means that that water is just going to sit there, no? I mean, your channels are seperated, to where they don't flow into each other!
I think you should be looking into a pinhole array that's 7 by x. |

For a 13mm slit that would be about 2-3mm depending on pump pressure.

Yes, exactly. If the channel walls touch the top of that peice and seal off each hole to each channel you should be able to control the flow of each channel and tweak it to the maximum effeciency. You might even be able to get 2 holes in the middle channels.
I might be way off base but it is a thought. Only thing that makes this different than a slit is you can make each hole bigger or smaller to tweak every channel. If you just use a slit and the channel walls touch the top you will still have the same effect but you will not be able to adjust the flow in each channel aswell. In theory anyway. |
