【摘要】 用脉冲管制冷机首次作低温箱的冷源进行可行性实验研究。已经建立起初步的系统实验装置,并进行了有关实验测试。实验结果和分析比较表明,脉冲管制冷机系统结构简单,运行可靠.具有优于低温氟里昂制冷系统的优点,而且在较高制冷温区的冷量输出可以满足冷负荷的需要,是替代低温氟里昂制冷系统的一个新途径。更多还原

【Abstract】 This is the first experimental work on the feasibility of operating pulse tube cryocooler as a low-temperature(-60～100℃)refrigerator. In relatively high refrigeration temperature range,the simple,reliable pulse tube cryocooler have some advantages over the conventional freonbased refrigeration technology,thus giving a profitable hint to the alternative technology of the CFCs.An initial unit is set up and the experimental results favourably support the new idea.更多还原
