APPARATUS FOR EVALUATING A THERMOELECTRIC DEVICE

摘要

PURPOSE: An apparatus for evaluating a thermoelectric device is provided to measure Seebeck coefficient, conductivity, and thermal conductivity at the same time by using a thermoelectric performance parameter. CONSTITUTION: A heating plate assembly includes temperature sensors. The heating plate assembly is placed in a main vacuum chamber. A temperature controller(340) is connected to the heating plate assembly. A data collector(310) gathers thermoelectric performance parameter information. A calculation unit(300) computes a thermoelectric performance index by using the thermoelectric performance parameter information.
