Abstract In a typical pulse tube cryocooler application, modeling the cool-down dynamics of a load attached to the cold tip require knowledge of the transient cooling power. Although this data may be calculated for in-house developed cryocoolers, the only data provided in commercial off-the-shelf cryocoolers is the steady state cooling power. In this paper, we show a systematic approach to derive transient cooling power data by performing heating and cooling experiments. The data obtained is verified with cooling data of an attached mass, which showed a good agreement. We also present a method to determine the parasitic heat load in a steady and transient operation of a commercial pulse tube cryocooler.

确定商用脉冲管低温冷却器瞬态冷却功率和热泄漏的系统方法

摘要 在典型的脉冲管低温冷却器应用中，对连接到冷端的负载的冷却动力学建模需要了解瞬态冷却功率。尽管可以针对内部开发的低温冷却器计算此数据，但商业现成的低温冷却器中提供的唯一数据是稳态冷却功率。在本文中，我们展示了一种通过执行加热和冷却实验来获得瞬态冷却功率数据的系统方法。获得的数据与附加质量的冷却数据进行了验证，显示出良好的一致性。我们还提出了一种确定商用脉冲管低温冷却器稳定和瞬态运行中的寄生热负载的方法。
