温差发电机（TEG）利用塞贝克效应将热能转化为电能，在余热回收方面具有巨大的潜力，而珀耳帖效应是能量转化过程中不可避免的负面效应。传热边界条件和珀耳帖效应对温差的影响是决定TEG发电性能的主要因素。为了研究传热边界条件和珀耳帖效应对三甘醇发电性能的影响，建立了实验系统。在实验中，TEG的热端初始温度由加热器控制，冷端由水冷却，属于对流换热边界。首先分析了在不同的热端初始温度下，由于珀耳帖效应引起的TEG热端和冷端温度的变化。然后，在不同的冷却条件下，TEG的温度，内部热流和发电性能进行了研究。结果表明，Peltier效应减小了实际温差，导致实验发电性能与理论发电性能之间存在差异。此外，强化冷侧传热边界条件可以提高实际温差，从而提高TEG的发电性能。同时考虑Peltier效应和传热边界条件时，冷侧传热边界条件的增强可以减小温度损失，从而减小Peltier效应引起的相对发电性能损失。当负载阻力为0.1时，水流量从0.1增加到7时，相对功率损失从29.01%减小到20.20%，相对效率损失从20.49%减小到13.60%。研究结果可为三甘醇的传热过程研究提供参考。
Thermoelectric generator (TEG) has great potential in waste heat recovery which can convert heat into electricity based on the Seebeck effect, while the Peltier effect is negative and inevitable during the energy conversion process. The heat transfer boundary condition and Peltier effect influence the temperature difference which is the main factor determining the power generation performance of TEG. In this paper, to figure out how the heat transfer boundary condition and Peltier effect influenced the power generation performance of TEG, an experiment system was established. In the experiment, the initial hot side temperature of TEG was controlled by a heater, the cold side was cooled by water which belongs to the convective heat transfer boundary. The temperature variation of the hot and cold side of TEG caused by the Peltier effect under different initial hot side temperatures was analyzed firstly. Then, the temperature, internal heat flow, and power generation performance of TEG under different cooling conditions were investigated. The results showed that the Peltier effect reduced the actual temperature difference and resulted in the difference between the experimental and theoretical power generation performance. In addition, the enhancement of cold side heat transfer boundary conditions could raise the actual temperature difference and thus enhance TEG’s power generation performance. Besides, when the Peltier effect and heat transfer boundary conditions were both considered, the enhancement of the cold side heat transfer boundary condition can reduce temperature loss and thus the relative power generation performance loss caused by the Peltier effect. When the load resistance is 0.1and the water flow rate increases from 0.1to 7, the relative power loss decreases from 29.01% to 20.20%, and the relative efficiency loss decreases from 20.49% to 13.60%. The findings of this work may provide a reference for the study of the heat transfer process of TEG.
