QUOTE (napalm @ dimanche 21 janvier 2007 à 20:14:30) :
the heat exchange surface must be crummy with 20 mm of copper between the core and the LN2
... and the column at the center ...
not very well
so, let's be honest, it's a well-made copper piece, it shines, but it's not a good evap
too heavy, and the base is not mahined
I think absolutely the opposite of this post
- 20mm is in the common range for CPU evaps
- the column at the center
is a good idea, it adds some surface area for the heat exchange (and conduction from base to top depends on the section of the column)
- base is machined... shiny doesn't mean good, and not shiny doesn't mean bad.
my only concerns would be related to details :
- I don't like the square shape, it's harder to insulate
- mouting part seems very high on the tube, you need xtremely long screws, and that's harder to install properly (well flat)
with all that copper mass, it must have been a PITA to braze it together ! no way to weld it ?
