Abstract
A theoretical and experimental study of high current density transient thermoelectric cooling is undertaken in this paper. Both three region and five region thermodynamic heat transfer models are implemented in the theoretical study and the transient heating and cooling temperatures are evaluated at various current densities. An experimental setup was devised to resemble thermodynamic assumptions necessary for an analytical solution. Temperature profiles are generated from the heating and cooling of mercury and compared to the theoretical predictions from the three and five region thermodynamic models. The transient agreement is excellent in the three region model for lower current densities ( ≈ 1 A/sq mm), although the steady state agreement is only marginal. The five region model qualitatively predicts the temperature profiles at higher current densities ( ≈ 3 A/sq mm).
