| Abstract: | In this paper,the numerical simulation and analysis are made specially for the unsteady temperature distribution of thermoelectric couple of thermoelectric refrigeration system under both the electric field and temperature field.The differential equation of thermoelectric refrigeration process is deduced and analyzed,and some effective factors to the cold-node of thermoelectric couple are analyzed in detail under unsteady condition.Through the unsteady numerical simulation and analysis,some fundamental function relationships have been discovered. |
