slope design?
 

I've been looking at most of the designs that this forum has, and I've been mostly impressed.
Since most designs now has jets to get rid of water stagnation above the core,
would it not be a good idea to use a slopes with the jets? The jet would then be in the center of 2 slopes that even out at the base, quite quickly. The slits should of cource still be there. This should then mean that water passing be the copper closest to the core would have full velocity, without stagnation.

There is another way to go with slopes, and that is if each slit has its own slope, but the startpoint would be offcet so that there would be no buildup of copper above the core. This way each other slit-slope would be in one direction. A 2 way output would be used, just like the RBX.

I'll see if I can figure out how to use sketchup, then I guess I could better "show" my idea!

Sounds like it will work. Keeping in mind that its good to have a violent turbulence at the core. On that note. Build the sucker already!

A drawing would help a lot. ;)

Otherwise the jet works best when it hits a flat plate head-on.

He is basically talking about a cone like the nozzel on the end of a water hose to increase volocity. \_/

a quick paint drawing might help:) So the middle cone in this drawing is the slope, its centered in the middle of the jet(guess the jet it not needed in this design?), right above the core. My idea is that the slope would help water to travel at high speed across the copper, nere the core where it counts. The fins/slits should of course still be there.

Just the opposite of what I was thinking. Increase volocity maybe bit it will remove turbulance.

I was thinking the opposite (too!). I thought he meant something like Nicozeg's ringed baseplate, but with radial fins cut into it.

It's like the pyramid block. The problem is that it effectively creates a thick baseplate, which causes an increased temperature gradient. Also, the inpingement effect is completely nullified, because the flow essentially gets redirected over the surface of the "baseplate", wether it be flat or cone shaped.

The inpingement effect throws water in high turbulence, as a result of "slamming" the water against the bp. This turbulence is what makes the heat transfer more efficient.

my guess is that it should be good for temps if high velocity non sticking water is in large copper contact near the core.

...and it was, back when we were trying to optimize the DD Maze 1 and 2 designs. Since then, we've discovered that jet inpingement performs even better than high speed flow, and the bonus is that it works well with a very thin baseplate.

The sketch shown above is pretty much like what the Atlantis had implemented, or at least that's my understanding of how it worked.

Looks like the idea is crap... Nice to be stopped before milling;)

Well, it'll work.

Honestly, I've never been a fan of the pyramid, but some people have done it succesfully. Was it Gone_Fishin?
