摘要:
针对宇宙空间温差发电装置缺乏有效的安全性和极限性能预测模型的问题，建立了空间热电元件的热-电-力多场耦合模型，对比了具有2种热电腿结构（宽a=1 mm，高h=1 mm和宽a=4 mm，高h=4 mm）、冷端温度178~298 K范围内热电元件的发电效率和热应力大小，论证了安全温度及其预测对于热电效率提升的重要性；分析了热电腿宽度a和高度h在1~4 mm范围内的变化对安全温度及对应极限发电效率和极限功率密度的影响，并利用拉丁超立方样本采集和人工神经网络方法构建出能够通过热电腿宽度和高度变化准确预测安全温度、极限电效率和极限功率密度的预测模型；通过多目标遗传算法给出了权衡极限电效率和极限功率密度的热电腿宽度和高度参数的最优解集，其中热电腿宽a=1.14 mm，高h=1.02 mm时具有较高的极限电效率（9.48%）和极限功率密度（153.35 W/kg）。兼顾安全温度和极限电性能的预测模型有助于热电元件的优化设计与性能提升。
Abstract:
In response to the lack of effective models for safety and limit performance prediction of thermoelectric devices in outer space, a thermal-electrical-mechanical multi-field coupling model for space thermoelectric elements is established. The power generation efficiency and thermal stress of thermoelectric elements under two kinds of leg structures (width a = 1 mm, height h = 1 mm and width a = 4 mm, height h = 4 mm) within cold-side temperature range of 178~298 K are compared, demonstrating the importance of safety temperature and its prediction for enhancing thermoelectric efficiency. The influence of variation of thermoelectric leg width and height within 1~4 mm on the safety temperature, the corresponding limit electrical efficiency and limit power density is analyzed. By collecting Latin Hypercube Samples and employing an artificial neural network, prediction models are constructed to accurately predict the safety temperature, limit electrical efficiency, and limit power density based on variations in the width and height of the thermoelectric legs. Using a multi-objective genetic algorithm, the optimal solution set including thermoelectric leg width and height balancing the limit electrical efficiency and limit power density is derived. Among these, the configuration with the leg width a = 1.14 mm and leg height h = 1.02 mm achieves a high limit electrical efficiency (9.48%) and a high limit power density (153.35 W/kg). The prediction model that incorporates both safety temperature and limit electrical performance contributes to the optimization design and performance improvement of thermoelectric elements.
