In this paper,the theoretical analysis and simulating calculation were conducted for a basic two-stage semiconductor thermoelectric module,which contains one thermocouple in the second stage and several thermocouples in the first stage.The study focused on the configuration of the two-stage semiconductor thermoelectric cooler,especially investigating the influences of some parameters,such as the current I 1 of the first stage,the area A 1 of every thermocouple and the number n of thermocouples in the first stage,on the cooling performance of the module.The obtained results of analysis indicate that changing the current I 1 of the first stage,the area A 1 of thermocouples and the number n of thermocouples in the first stage can improve the cooling performance of the module.These results can be used to optimize the configuration of the two-stage semiconductor thermoelectric module and provide guides for the design and application of thermoelectric cooler.
