Pro/Forums - View Single Post - The "Cascade" - mini-cup directed jet-impingement block design (56K warn)

The reason for the elongated tubes are these:

1) The height of the jet stream above where it strikes is actually important. At present I have it a little too high, even with the tubes. Am fixing that.

2) The tubes are there to stop the flow from other cups interfering with the jet streams.

Now the first prototype I made without the jet tubes was about 25% more dense than the tubed version, yet the tubed version just pips it. The next step is to get the tubes even smaller and increase the density to match that of the first revision, better balance the jet heights, and balance the base-plate thickness from CPU to bottom of the holes, and work on getting the cup shape tweaked.

All of these things will be addressed in the next step, and it's going to be some pretty intricate stuff that will make the current jet-tube plate look almost clunky in comparison.
