Experimental Study of a Thermoelectric Conversion System for Low and Medium Temperature Heat Utilization in Space
Online published: 2025-07-18
随着空间探索和月球基地建设的推进,中低温热利用技术在太空环境中的应用变得日益重要。在此背景下,研究开发并验证了一种基于有机朗肯循环的中低温热电转换系统。由于空间和月球环境的极端条件,选择了结构简单且运行可靠的特斯拉涡轮作为膨胀机展开试验,并对该系统在不同温度、压力和流量条件下的变负载性能表现进行测试。试验结果表明,基于特斯拉涡轮的中低温热电转换系统能够有效地将中低温热能转化为电能。在90~130℃、压力低于2 MPa的条件下,系统可实现30 W以上的稳定功率输出。研究验证了特斯拉涡轮在空间中低温热利用方面的可行性,为未来空间站和月球基地的能量管理提供一种新的解决方案。

With the advancement of space exploration and the construction of lunar bases, the application of low and medium-temperature thermal utilization technology in space environment has become increasingly important. Based on this background, this study develops and validates a medium and low temperature thermoelectric conversion system based on the organic Rankine cycle. Considering the extreme conditions of space and lunar environments, a simple and reliable Tesla turbine is chosen as the expander for experiments. The system's variable-load performance is tested under different temperatures, pressures, and flow rates. The experimental results indicate that the medium and low temperature thermoelectric conversion system based on the Tesla turbine can effectively convert medium and low temperature thermal energy into electrical energy. Furthermore, the system can realize a stable power output of more than 30 W in the temperature range of 90~130℃ and the pressure range of less than 2 MPa. This study demonstrates the feasibility of the Tesla turbine for medium and low-temperature thermal utilization in space, which is expected to provide a new solution for energy management in future space stations and lunar bases.
