12 Vdc heater / cooler assembly utilizes a Peltier device to create heat on one side and cold on the other. Driven by a 40 mm square Peltier thermoelectric heat pump, it operates on 13 Vdc @ 5 Amps. Operating at 13 Vdc, we measured the hot side at 190 Deg. F and the cold side at 55 Deg F.
The hot side of the Peltier device is connected directly to a 4.0" x 4.5" x 1.5" heatsink. The cool side connects via an aluminum block to another heatsink that is 5.0" x 5.0" x 1.25". The overall thickness of the unit is 3.8". The Peltier device and the aluminum spacer are between the heatsinks, embedded within an insulating block 1.1" thick. See online "Spec Sheet" section for a disassembled picture. 8" wire leads. Weight: 2.6 lb.

Can this be used as a seebeck device?
If I mounted one of these with one side on a hot surface, the other cooled, would it produce a voltage? Any info on how much, as a function of delta tee?

Tip for use of this type of product
From using a similar-sized product from my old refrigerator/warmer, I advise using a high-velocity fan, pulling air through the hot side fins and exhausting it upwards (if using it for cooling). Using a hair dryer (on cool) and placing the rear (intake) side on top of the hot side fins and blowing the air up and away, I have managed to get temperatures well below the freezing point of water on the cold side when measured with a thermocouple touching the cold side directly.
