| 中文摘要:斯特林制冷机驱动器元器件的散热问题一直是斯特林制冷机在高温环境下稳定运行的主要限制因素。本文以某款斯特林制冷机为研究对象，通过具体的驱动器元器件的散热结构设计来优化其散热特性。通过试验，验证了优化后散热结构的可靠性及散热提升效果，热真空环境温度60℃条件下，应用该散热优化结构的斯特林制冷机的驱动器元器件的平均温降约7.18%。通过试验得到，在热真空环境温度60℃条件下，使用紫铜作为背板材料的元器件平均温度会比使用铝为背板材料的元器件平均温度低约9.05%，制冷机反向放置时元器件平均温度会比正向放置时元器件平均温度降低约19.25%。本文设计的散热优化结构和试验过程及结果，对具体的工程实际可作出实质性的指导。 |

| Abstract:The heat dissipation of the drive components of the Stirling refrigerator has always been the main limiting factor for the stable operation of the Stirling refrigerator in the high temperature environment. This paper takes a Stirling refrigerator as the research object, and optimizes its heat dissipation characteristics by designing the heat dissipation structure of specific driver components. Through experiments, the reliability of the optimized heat dissipation structure and the heat dissipation improvement effect are verified. Under the thermal vacuum environment temperature of 60 ℃, the average temperature drop of the drive components of the Stirling refrigerator using the optimized heat dissipation structure is about 7.18%. According to the test, under the thermal vacuum environment temperature of 60 ℃, the average temperature of components using red copper as the backplane material will be about 9.05% lower than the average temperature of components using aluminum as the backplane material, and the average temperature of components when the refrigerator is placed in the reverse direction will be about 19.25% lower than the average temperature of components when the refrigerator is placed in the forward direction. The heat dissipation optimization structure, test process and results designed in this paper can provide substantial guidance for specific engineering practice. |
