"Manifolds"

[mrplow]

I know you don't sell these pug, but I hope you don't mind me asking about them - this place seems to have the best collective watercooling knowledge of the forums I frequent :)

I wondered how these work:

They claim to split the flow evenly... but if the water comes in at the end, where the plug is in the picture, surely the first block would receive more pressure than the next and so on - like experiments back at primary school!

Anyway, aside from that, I was also thinking the small ones could make pretty darn good makeshift ramblocks? They'd look quite pimp on a graphics card / ram / fets... perhaps the bigger ones for hard disks?

Any input/comments much welcomed and appreciated :)

I'd imagine that for a four way split, using cascaded Y-connectors would work fine and be much less bulky.

No probs mrplow - I've looked into something very similar (http://www-1.legris.com/webapp/commerce/command/ProductDisplay?prrfnbr=3778&prmenbr=361) myself a long while back but it's so easy for people to go wrong with this approach (unless they have the ability to monitor/control flow in the individual branches), I didn't want to propound it without doing some serious research into it first, so I decided against offering them for sale until I could properly support the end user with regard to them..


Personally, I was more taken with another range I saw that had a modular approach for much more flexibility (plus the ability to fit control valves for each branch) but I'm of a similar mind to Risky (if only I could find the unequal splitters I want whereby the inlet would be larger than each individual outlet).

I'd have thought cascaded y-connectors would in fact be much more bulky?
I can see how they'd be more likely to give an equal split in flow however.

This is a really nice looking solution, but as I said before surely the connectors closer to the supply would take more of the water pressure.

Pug were you suggesting you still need to look into to these things, or do you have a good suggested method for their use?

Anyway, it looks like a very tidy way of splitting for gfx and cpu, since it could clamp very neatly to the case frame even looks pretty enough to be a feature piece. Taking the first feed for cpu might also mean the increased flow in the first channel would be a nice side effect?


I still think they would make nice ram-blocks :)



edit:
Am I looking at these things wrong, do you in fact use the central port for the "in" and then take feeds from the ports around it? That would seem to me to give a more even distribution..

Well, from my experience with manifolds, even though you may get even flow without plumbing them in, if you have different lengths of pipe, degrees of internal restriction in differing types of block and heights of components coming into play, I think you're asking for trouble.

can be used to split the water flow ensuring equal supply to 5 water blocks is a little vague, imho.
Yes they can be used to do this but I can virtually guarantee that there will be instances where this doesn't automagically happen. :p

You could say that if you used 5 identical blocks (like hdd blocks) but what kind of pump would you use which could make these much of an advantage over a serial setup using a lower powered pump?
