gee, the heavy hitters are gonna beat up on the Gemini again
but it is fun
ok, the question was pretty much rhetorical in that Peter cannot answer it
but there is quite a bunch that is known, it impacts directly on wb design
- and most wb designs are headed in quite the wrong direction
the distance from the source of the heat is the dominating factor,
all that real estate 1.5 in. from the die is so much junk
it is the heat convection rate that needs optimization within 1 in. of the die
long channels, folded or curved, don't do it
and deep channels are worse yet
I skirted the question of geometries on the other thread, but lets compare several:
how is it that an un-finned design (Swiftech) can be about equal to a labyrinth ?
different 'levels' of execution ? or different intrinsic 'merit' to the design ?
can the mods that improve a Swiftech ALSO improve a labyrinth ?
(am doing so now, should know in several days)
from my perspective its all about that prime real estate in the die area
and of course ALL readers are thinking INTENTLY about the BMW of wbs:
