摘要

斯特林脉冲管制冷机在小型化设备的冷却方面具有重要的潜力。本文研究了气耦合三级斯特林脉冲管制冷机的数值设计与优化，并通过后续实验进行了验证。在第三阶段优化了惯性管的长度和双进气口的配置后，样机在9.5 K时达到了8.6 K的最低空载温度和25 mW的制冷量，输入功率为500 W。据我们所知，斯特林脉冲管制冷机的最低温度可以达到10 K以下，这可以作为液氦温度下小型脉冲管制冷机的研究路线之一。

Progress on An 8 K gas-coupled three-stage Stirling pulse tube cryocooler

Stirling pulse tube cryocoolers hold significant potential for cooling in miniaturized devices. This paper investigates the numerical design and optimization of a gas-coupled three-stage Stirling pulse tube cryocoolers, which has been validated by subsequent experiments. Following the optimization of the length of inertance tube and the configuration of double-inlet at the third stage, the prototype has achieved a minimum no-load temperature of 8.6 K and a cooling capacity of 25 mW at 9.5 K with an input electrical power of 500 W. To the best of our knowledge, the lowest temperature of Stirling pulse tube cryocoolers reaches below 10 K, which can be used as one of the research routes for small pulse tube cryocoolers in the liquid helium temperature.
