Summary

Part 5 of this study covers the basic characteristics of pulse tube coolers. In the first section, energy flow concepts are reviewed using graphical representations. Three different categories of the cooling effect obtained by flow oscillations without having a solid expansion piston are described based on the phase difference between the pressure and gas displacement within the system. In the second section, numerical calculations for different types of pulse tube coolers are performed to clarify the loss mechanisms. Consequently, the method of thermodynamic efficiency improvement is discussed. See also the Bulletin of the IIR, references 2007-1381, 0459, 0462 and 1814.
