摘要：

针对空间35K温区探测器的冷却需要,结合回热器数值计算软件REGEN3.2的计算分析,自行研制了一台第二级脉管采用低温惯性管和低温气库的热耦合型两级高频脉管制冷机.实验研究了充气压力、工作频率、输入功率等对第二级脉管制冷机性能的影响.实验得到35K下最佳充气压力为1.26MPa,最佳工作频率为40Hz,从而验证了理论计算结果.实验结果表明,在充气压力为1.26MPa,工作频率为45Hz,输入功率为135W的条件下,获得了27.4K的最低无负荷制冷温度；在充气压力为1.36MPa,工作频率为40Hz,输入功率为205W的条件下,制冷机在35K获得了0.45W的制冷量.
Abstract:

For the requirements of detectors cooling at 35 K in space application, based on the calculation and analysis from the regenerator simulation software known as REGEN 3.2, a self-designed two-stage Stirling-type pulse tube cryocooler (PTC) for 35 K with cold inertance tube and cold reservoir at the second stage was manufactured and tested. Experiments on the effects of charging pressure, frequency, input power on the performance of the second stage PTC were carried out. The optimum charging pressure of 1.26 MPa and the optimum frequency of 40 Hz for 35 K were obtained, which agreed well with the theoretical calculation. The lowest no-load temperature of 27.4 K with the charging pressure of 1.26 MPa and the frequency of 45 Hz together with 135 W input power was obtained. The cooling power of 0.45 W at 35 K with the charging pressure of 1.36 MPa and the frequency of 40 Hz was also obtained with an input electric power of 205 W.
