The Demonstration Duct Assembly is designed for insertion through the wall of a duct or pipe containing flowing hot gas or liquid. The heat from this source can generate electricity directly.
Heat is rejected from the cold side to air.
Aluminum oxide insulators are used between the hot and cold surfaces of the module and the corresponding heat exchangers to electrically isolate the module from the adjacent metal surfaces. This converter changes the nominal 2.3 volts produced by the module to 12 volts DC for the cold side cooling fan. The cold side cooling fan draws 2.6 watts of power and has an air flow of 82 cfm at 0 static pressure. The positive connection is terminal 4 and the ground connection is terminal 3. The output voltage at the module connection will range between 0 volts and 4.7 volts, depending on the module temperature and load.
