摘　　要：基于非平衡热力学理论,对联合半导体热电装置循环模型的工作温差进行研究。分别针对热电发电机驱动热电制冷机和驱动热电热泵两类循环模型,给出了一定热源条件下,装置的极限工作温差同热电单元比的关系,并研究了极限工作温差随发电机高温热源温度的变化规律。The working temperature differences of thermoelectric generator-driven thermoelectric refrigerator and thermoelectric generator-driven thermoelectric heat pump were analyzed based on non-equilibrium thermodynamics. The extreme working temperature differences versus the ratio of number of thermoelectric elements, i.e. the ratio of the number of thermoelectric elements of the generator to the total number of thermoelectric elements of the combined devices, of the two models were derived. The effects of the generator heat source temperature on the extreme working temperature differences were analyzed.
