SOLVED TEC question, not for a cpu

[wagex]

if i were to have lets say 3 100w tec's stacked ontop of eachother in series would the total heat dump be 300w?
this isnt going to be part of a computer i just need a controllable heat source

heres a crappy diagram of how i was thinking
c=cold side h = hot side t=tim

ch-t-ch-t-ch (300w of heat?)

would the cold side benifit from having a heatsink on it to help keep warmth going into it to be pumped out the other side?

I think what you would mostly have is a fried TEC. They don't stack well unless they're staged in wattage also.
A 50w can be cooled by a 100w that is cooled by a 200w.
A 100-100-100 gives the last poor tec something over 200w of heat that it has to move, plus the 100 going into itself. A 100w tec can successfully move 30-75w of heat (roughly, it varies widely by the delta-T you want).
If you lined 'em in in parallel, it'd be fine.
Putting a heatsink on the cold side will increase the total wattage on the hot side as more heat is being picked up from the air.

What're you plotting to do? I may have Brilliant Ideas of Dubious Sanity

oh weel see crap i guess that idea isnt going to work at all need to find a better way to generate heat lol i think i found the ticket 200w can be run in series and not tec's

edit also found some 500w beast ;D i think i r ready

just ordered the 500w beast
holy crap ive spent way too much today lol

You didn't spend too much You spent too much when they can't afford to toss your old dead body in a paupers grave. Everything before that is already spent on 'good times'.

indeed the creation shal be showing its face in the next couple weeks

Now, that's a cool way of thinking. I will surely use it to justify upgrading my SLi for a single 780 when they're released.
