    摘要: 本計畫針對台灣本地使用環境與需求,發展史特靈引擎(Stirling Engine)熱電系 統為主要單元,用以介入一般光-電轉換模式,首先將光能轉換為熱能,作為熱電系 統之輸入源,而後再將熱能轉換為電能加以儲存及應用。本計畫之執行重點包含太陽 能集中器系統、史特靈引擎、高溫液態金屬熱管熱接收器之設計製造與性能測試;與 由史特靈引擎驅動的線性發電機組件之發電效率改良。 經由本子計畫的執行,對整體發電效率提升將有如下三個部份的貢獻:(1)發電機 結構參數的最佳化,有助動能轉電能的效率提昇,(2)飛輪的移除,使用磁力回復式的 創新技巧,配合free piston 架構,以迴避飛輪機械傳動能量過程中的各種阻力與摩擦造 成的損失,(3)free piston 的密封式架構解決了工作氣體逐漸洩漏的問題,有助熱能轉動 能的效率提昇。另外,以磁鐵的斥力來取代機械彈簧回復力則可避免彈性疲乏的問題。
    This is a proposal of green energy technique for local environmental requirement in Taiwan. By making capital of Stirling engine as main module for solar combined heat and power, the study will covert energy transferring processes from solar energy to electricity. Firstly, solar energy is transferred to heat by solar collector, then heat may be applied to start Stirling engine and generate electric power. Finally, electricity will be used for storage and practical applications. The development task of this study will be Executed focus on Design, manufacture and test of solar concentrator, Stirling engine, thermal receiver with liquid metals heat pipe. Another main goal is to investigate the linear electricity generator driven by a Stirling engine, and focuses on the improvement of power generation efficiency. Through the execution of this project, the contribution to the efficiency enhancing of power generation can be attributed to three parts: (1) the optimal design of structure parameters of generator for the efficiency improvement of kinetic energy to electricity conversion, (2) remove of the flywheel, the innovative use of magnetic restoring force, with the free piston structure to avoid various resistance and friction losses due to the use of mechanical flywheel for energy transmission, (3) the sealed architecture with free piston can resolve the problem of the gradual leakage for working gas, which in turn help the conversion efficiency from kinetic energy to heat. In addition, the utilization of magnets repelling force to replace the mechanical spring force can avoid the elastic fatigue problem.
