AB  - High frequency pulse tube cooler has shown great prospect due to its high power density and high specific power. In this paper, a 300 Hz two-stage pulse tube cooler with random fiber as regenerator material has been numerically investigated. Firstly, the dimensions of the system have been optimized after extensive simulations. With the optimal dimension, the influence of the mean pressure and the inlet pressure ratio on the system performance has been studied. Then, emphasis has been put on the dependence of the wire diameter and the porosity of stainless random fiber on the cooling performance. Furthermore, the stainless steel screen and the stainless random fiber, two kind of the packing materials of the regenerator, have been compared. With the inlet pressure ratio of 1.2, the calculated results show that a no-load temperature of 26.4 K has been achieved in the system filled with 8 μm-wire diameter and 85%-porosity random fiber, which is almost 10 K lower than the no-load temperature in the system filled with stainless steelscreen.
