Abstract

General governing equations for generic galvano-thermomagnetic devices are derived from the principles of irreversible thermodynamics. Two mathematical models for the Ettingshausen refrigerator are formulated of which one is the system considering the current density as the controlling variable and the other with the potential gradient as the controlling variable. Theoretical solutions are found for both static and dynamic responses of both systems. An experimental Ettingshausen refrigerator was constructed and measurements were made for both static and dynamic responses. Comparisons of static and dynamic behavior of theoretical solutions of both systems with measurements are made and discussed. Conclusion is reached that the one dimensional mathematical model with current density as the controlling variable was proved to be adequate in representing the thermal behavior of the Ettingshausen refrigerator.
