hmm, the bulkyness is undesirible.
hence the reason i was wanting to use the Peltier rather then a standard compressor.
The liquid idea was another thought, feron or possibly just metho could run through tht etubes, and thus conduct the heat better.
The problem then is how to pump it on such a small scale, the tubes couldnt be any smaller then half a CM or a tad bigger, and the flow would have to be slow.
i really wanna make this work guys.
instead of a trapdoor, what about one of those folding fans, they fold completely flat when no power is applied.
I like the idea of the temp switch on the actual heat sink.
i think i am going to purchase some modules to play around with.
any more ideas.
Liquid Cooling gets even more complicated, and you still need a Good Radiator to dispurse the heat to the air. And at 80 Degrees, your lucky if you can keep the heat sink on the hot side lower than 90 Degrees, no matter which system you use.
Also Available are Multstage Peltier devices. More Expensive but they do achieve Higher Temperature Differentials.
I believe I show aTwo Stage one on my website.
(They also come in 3 Stages, maybe higher now)
However, The heat pumping capacity, along with the Insulation factor and the refigerator volume will determine how cold it gets.
No Matter what else, One Inch of Insulation is NOT Enough for a fridge, unless you only want 40 to 45 degrees with an outside ambient temperature of 80 degrees.
Than there is the Battery Consideration. Drawing 5 or 10 Amps for even relatively short periods of time can deplete a battery Pretty Quick.
I have been using these devices for over 30 years and there are No Simple shortcuts.
Cooling a Slide on a Microscope to freezing is Quite Simple because of the Small Size, but a Fridge is another thing.
