温差电组件串并联连接的热阻解析模型
Thermal resistance analytical model for thermoelectric component with series-parallel connection
摘要
Abstract
In order to choose the appropriate thermoelectric components and external heat exchangers,the thermoelectric generation system with series-parallel connection of thermoelectric components was investigated according to the non-equilibrium thermodynamics theory and Newton cooling law,and the thermal resistance analytical model for system output power was derived.In addition,the effect of total number of thermoelectric components,number of components with parallel connection,thermoelectric module as well as thermal resistance at both hot and cold ends of the module on the system performance was discussed.The results show that there is a matching relationship between the system resistance and load resistance.Moreover,the thermal resistance of thermoelectric module and the thermal resistance at both hot and cold ends of the module also exhibit a matching relationship.Therefore the maximum output power can be obtained for the system.With increasing the number of components with parallel connection,the maximum output power and loop current get enhanced,while the output voltage of the system decreases.The present results can provide the theoretical reference for the reasonable assembly and performance optimization of thermoelectric generation system.关键词
