A repost*:- "Peltier Calculations - Am I mistaken?

"I am not actively engaged in playing with Peltiers at the moment.
However my currently favored Kryotherm parameters may interest :-
Rc=0.19 - 0.26 (for 40x40x6 mm Cold plate with a 10x10mm heatsource)
Based on:
1) C/W(TIM,Die/coldplate) ~0.1 - from Bill Adams work(e.g http://www.overclockers.com/articles654/index02.asp ) ,making an allowance of 0.05c/w for die thermocouple offset.
2) C/W(Coldplate) ~ 0.09 to ~ 0.16 -- from Waterloo calculations using,possibly mistakenly, an h=10,000 - 100,000W/m*m*c as corresponding to the conditions for a 172W Pelt cooled by a wb with a C/W=0.00625 - 0.0625(cooling a 40x40mm heat source).

Ri=1
Based on my current attemps to cross-correlate Bill Adams data with CPU(Diode)/"Radiate calculated Watts"

All are very iffy and only the thoughts of a dilettante." "
