This is one for the TEC specialists as my TEC knowledge is rather basic :)

upfront: i KNOW this can NOT be used to house/cool a PC... it just does not have the power/capacity :)


So, for completely different reasons i stumbled upon this Coleman cooler
http://www.coleman.com/product/40-q...ectric-cooler/3000001495?contextCategory=8570

Coleman claims this thing can drop to approx 40 °F below ambient in about 3 Hrs
This on itself is not fantastic to start with, but is acceptable to cool your beer when "on the move"

By digging deeper, i found this thing runs nominal 4 Amps at 12 volts
Given that most likely at least 1 Amps "goes to" the fan(s)... i deduce this uses a 40 Watt (or rather 36 watt) TEC

Am i right?



Now, i KNOW this cannot handle any heatload over 30 W - just like any (mini) fridge is unable to handle that... so it would definitely NOT be able to handle a +500 Watt PC ... although you CAN fit a PC inside :) :)

But the concept is sound:
Use a hermetically sealable insulated "box" , sandwich a few decent TECs between (huge) heatsinks
for example: http://www.wisefull.com/goods-158-工業系統用散熱片-01.html
put fans on both sides.. cool the box, dump the heat into the environment :)


But what are we looking at then?

To drop a +500 Watt heatload to (below) ambient on the cold side i suspect needing multiple TECs ... AND i'll probably have to deal with +1500 Watts to dissipate on the hot side... which probably means watercooling ... which probably means custom waterblocks (+ a MO-RA rad)

Any ideas/suggestion on the TECs? Or ideas in general?
No saying i'm going to build this... just kicking the tyres a bit :)
But if it can be done wihtout need too much complicated expensive custom parts, i might give it a go.


And yes, i know that A/C would be more efficient to build a cold/chill box... but that would be overkill, unless someone can point me to a small 2000 BT/U A/C unit.


UPDATE: To clarify: i dont want to run a chilled water loop; i know how to do that - basically hang a rad outside the window in winter :)... no, i basically want to stick the WHOLE PC into "cold storage" ... which "solves" a lot of headages with routing & condenstation.

How would shoving a PC into a cooler help with condensation?

Because in a (hermetically) sealed box, you have a controlled environment.

Once the air inside is dry, you can heat it and cool it without too much worry... as long as you do NOT introduce "new" external "moist" air you're fine.

Look at it like a fridge/freezer... as long as you keep the door closed you're fine :)
 
That's not why things don't get condensation in a fridge........

true
a fridge has nothing to do with this, i should not have made a reference to a fridge.... except maybe like "keep the door closed, keep beer cool & milk fresh"
