Stirling pulse tube cryocooler using an active displacer

Abstract:

An in-line pulse tube cryocooler with an active displacer has been built and its performance has been examined in detail by experimental measurements and numerical modelling. An active displacer allows the mass flow at the cold end to be easily adjusted for optimum performance. It is demonstrated that both cooling power and relative Carnot efficiency have optimum phase values that are different. It is also shown that the phase optimisations are not critical – good performance is achieved over...
