摘要
对40W/20K单级G-M制冷机系统的蓄冷器进行了结构设计,根据计算传热学和变质量系统热力学的理论,建立了G-M制冷机蓄冷器的物理模型和数值计算模型,并进行了数值仿真计算,得出了蓄冷器的温度分布规律,为大冷量制冷机的研制提供了理论依据。
The structure of A 40W/20K single-state G-M refrigerator has been designed in this thesis. According to the theory of heat transfer and thermodynamics of variable mass system, the physical and numerical model of G-M refrigerator has been built. Then the numerical simulation calculation has been carried out. It can predict the distribution of temperature of refrigerator and provide the theoretical basis of the research of high cooling capacity refrigerator.
