中文摘要：
在U型脉冲管制冷机结构基础上，研制了一台带有一个蓄冷器和两个相同脉管的新结构U型脉冲管制冷机，并进行了实验研究和分析。制冷机采用惯性管调相，在压缩机输入电功率80w，运行频率52Hz下，获得了120K@6W的制冷量。重点对两种惯性管调相方法进行研究和分析，得出了对新结构U型脉冲管制冷机调相有益的结论，并对惯性管调相过程中产生的直流现象进行了验证分析。
英文摘要：
A new structural U-shape pulse tube cryocooler based on the U-shape pulse tube cryocooler, with one regenerator and the same two pulse tubes, has been designed and manufactured. The pulse cryocooler is able to gain 120 K@6 W cooling power with 80 W electric power at the operating frequency of 52 Hz. The method of the inertance tube phase-shifting is investigated and the useful conclusion is obtained for the pahse-shifting of new structural U-shape pulse tube cryocooler. The DC flow that occures in the inertance tube phase-shifting is also tested and analysed.
