Im trying to understand the way a peltier modules behave as they are new and intriuing to me, I have ordered a few tec1-12705 units from china and done a little research trying to understand it.
Some discoveries indicate they are essentially a short circuit of 2 opposing metals with a 12v 6amp max safe running current. This coupled with having been informed they will consume whatever power you throw at them up to the max limit makes me suspect that they effectively have little to no impedence, making me question if series chaining these modules would effectively reduce any voltage or tecnically be consuming much of any energy them selves so much as they are mearly allowing the power to flow to ground freely, thus making me question:
Could I effectively chain 5 of these to recieve more efficiency out of the power delivered through it or am I mistaken in this?
Does the total power flow cause the effect ie 2 peltiers in series divide the voltage/amperage from 12v 4amps to 6v 2 amps each effectively being used per module or does the effective short allow the current to continue substantially unhindered.
I dont have alot to invest in experimenting or testing but have heard that these units do run more efficiently at lower voltages which makes me question what kind of test I could even manage to show the above.
In the experiments I have done I've found any standard power supply hooked directly to the unit tends to overheat likely as it is running at max flow, though I have also fried one module with 12v but too many amps, which seems to suggest to me these do not work the same way I am used to dealing with things related to power consumption....I figure this is related to the ressistance being low though but still leaves me questioning if I'd be better off running the modules from a motor working as a generator than trying to use it from a power supply.
