室温推移活塞脉管热机的四种运行模式

Four Operating Modes of Pulse Tube Heat Engine With Displacer at Room Temperature

脉管制冷机可看作是是斯特林制冷机的变种,带室温推移活塞的脉管制冷机是一种可逆脉管制冷机,与斯特林制冷机一样可工作于四种模式。本文采用数值分析的方法阐述了脉管热机的四种工作模式,即热发动机,热泵,制冷机和冷发动机。

Pulse tube refrigerator is a kind of Stirling refrigerator.The pulse tube refrigerator with a displacer at room temperature is a kind of reversible pulse tube refrigerator,which can also works at four operating modes.In this paper,we discuss the four operating modes,which are pulse tube heat engine,pulse tube heat pump,pulse tube refrigerator and pulse tube cold engine.
