| description | Summary: To address the critical need for energy-efficient and environmentally sustainable cooling technologies, the thermoacoustic-Stirling duplex cryocooler (TSDC) offers a promising solution due to its high efficiency and versatile applications. However, the limited cooling capacity of individual TSDCs poses a significant challenge for practical implementation, necessitating system upscaling. To enhance power density and performance, we optimized a resonance tube-coupled TSDC by incorporating a coiled resonance tube and developing an active displacer modeling approach. A prototype with optimized dimensions was constructed and tested, demonstrating a linear relationship between cooling power at 130 K and input heating power, with a maximum cooling capacity of 380 W achieved at an exergy efficiency of 6.36%. Compared to prior studies, which reported no cooling power at 110 K, this represents a substantial advancement in TSDC scalability. Comparative analysis of experimental and theoretical results suggests that asymmetric flow at the compression junction adversely affects efficiency, providing valuable insights for further optimization. |
