A method of measuring the thermal conductance and the heat capacity of a nanowire is presented. The nanowire is suspended in vacuum to ensure the thermal isolation, and the resistance is measured with respect to the square of the current to obtain the thermal conductance in the length direction. The heat capacity is evaluated by the frequency response of the 3f component of the voltage across the...
A thermoelectric generator (also known as a Seebeck generator) whose current is controlled by a periodically-operated switch is considered. The steady state analysis is therefore performed on a periodically switched nonlinear circuit. An iterative procedure is proposed in which the nonlinear resistor is replaced by a “generator” containing an ideal voltage source controlled by the voltage of the nonlinear...
A thermoelectric equipment (TEE) is constituted of heat sink and thermoelectric generator (TEG), and other components. The dynamic model for both heat sinks and TEGs are built up. Then the TEE's equivalent circuit model is gotten. Its source response characteristic and load response characteristic are analyzed. The results indicate that the output response for heat source step signal shows a large...
