With a cooler
that is chip/plate/water don't you want to keep the "plate"
as thin as possible?
Jep, since phi = lambda*S*delta-T / delta . Just, I didn't use a
simple plate and only one waterlayer, but rather a system of pipes
(drilled holes) to have a) a better controll for the water flow and
b) enlarge the plate / water contact by three. As larger the
surface (S) as higher the possible thermal current (vulgo amount
of transported heat). I can't enlarge the chips surface, so S is
fixed between chip and 'plate', but I can enlarge S between 'plate'
and water.
The minimal thickness is defined by your tools and skills - I used
0.8 mm (~1/30 inch) as minimal thickness betreen one pipe and the
chip.
