热电发电机通过有效回收汽车尾气中的废热来发电。中间流体温差发电器通过介质的气化和冷凝来传递废热，可以提高功率输出，减小最佳模块面积，从而显著提高功率密度。为了研究排气参数对新型发电机性能的影响，建立了温差发电机的数学模型，分析了排气参数对系统性能的影响。与传统的温差发电器相比，新型温差发电器具有更低的排气传热系数。研究发现，影响其性能的关键参数是排气换热器的导热系数。排气温度对最佳组件面积没有影响，但最大输出功率随排气温度的升高几乎呈线性增加。在保证排气充分换热的条件下，随着排气流量的增加，最佳模块面积呈线性增加。研究结果对于充分认识IFTEG的工作原理和指导IFTEG的优化设计具有一定的意义。
A thermoelectric generator generates electricity by effectively recovering the waste heat from the exhaust of automobiles. The intermediate fluid thermoelectric generator transfer exhaust heat by the gasification and condensation of the medium, which can improve the power output and reduce the optimal module area, thus significantly increasing the power density. To study the influence of exhaust parameters on the performance of new generator, a mathematical model of the thermoelectric generator is used to analyze the effects of exhaust parameters on the system performance. Compared with the conventional thermoelectric generator, the novel thermoelectric generator becomes more advantageous with a lower exhaust heat transfer coefficient. And it is found that the key parameter affecting the performance is the thermal conduction of the exhaust heat exchanger. The exhaust temperature has no effect on the optimal module area, but the maximum output power increases almost linearly with the increase of exhaust temperature. With the increase of exhaust flow, the optimal module area increases linearly under the condition of sufficient heat exchange of exhaust. The results of this study have certain significance for fully understanding the operation principle and guiding the optimal design of IFTEG.
