摘要
斯特林循环是一种由两个等温过程和两个等容过程组成的概括性卡诺循环,具有理论上最高的动力转换效率,在空间电源、潜艇动力、太阳能发电、低温制冷等领域具有独特的应用优势。对比了百瓦级同位素-斯特林热电装置和千瓦级空间堆-斯特林电源系统的主要性能指标,对斯特林发电机的热力循环效率、关键技术瓶颈等进行了初步分析,可以为斯特林动力转换技术的工程应用和选型论证提供技术支撑。
Stirling cycle is a generalized Carnot cycle composed of two isothermal processes and two isovolumetric processes,which has the highest theoretical energy conversion efficiency and unique application advantages in the field of space power supply,submarine power,solar power station,and low temperature refrigeration.The thermal cycle efficiency and key technical bottlenecks were analyzed preliminarily,with the comparison of the main performance indicators of hundreds-watt isotope-Stirling thermoelectric device and kilowatts space reactor-Stirling power system.It could provide technical support for the engineering application and selection demonstration of Stirling power conversion system.
