蓄冷器是脉冲管制冷机等回热式制冷机的关键部件,它性能的好坏直接影响到回热式制冷机的效率和性能。交变流动蓄冷器中的热量和动量传输及转换过程是一个十分复杂的传热学、流体力学及热力学问题。低温中心针对交变流动蓄冷器的特点建立了动态参数测试实验台。实验台可以模拟各种脉冲管制冷机的真实运行条件。针对50Hz的交变流动蓄冷器的阻力特性进行了系统的实验研究,第一部分介绍实验装置及数据处理系统。
The regenerator is a key component of the regenerative refrigerator such as pulse tube refrigerator. The performance of the regenerator directly affects the efficiency and performance of the regenerative refrigerator. The flow and transfer of heat and momentum in an ACF are a very complex problem of heat transfer, fluid mechanics and thermodynamics. The cryogenic center established a dynamic parameter test bench for the characteristics of alternating current regenerator. The bench can simulate the real operating conditions of various pulse tube chillers. Aiming at the resistance characteristics of 50Hz alternating current regenerator, a systematic experimental study is carried out. The first part introduces the experimental device and data processing system.
