Modeling of Thermoelectric Coolers for Freezing/Thawing Applications
Thermoelectric coolers are often used in freezing chuck to freeze or to thaw easy broken egg-shells, clays, and other ferrous/nonferrous materials, which are incapable to machine it by other clamping technology. For design and application purposes, detailed studies of freezing/thawing processes by thermoelectric coolers are inevitable to the success of this technology. In this study, an experiment to measure the thermal resistance of single thermoelectric device is conducted and a model to calculate its hot and cold side temperatures is derived. Moreover, a design case of freezing chuck system is analyzed by COMSOL software to investigate the freezing/thawing functions and to evaluate its effectiveness.
