Abstract

A single stage four-valve pulse tube cryocooler with a large cooling power at 80 K has been built and tested. The cryocooler has a regenerator stacked with stainless steel screen disks of 250 mesh, and a pulse tube of 200 mm long. A rotary valve unit is employed to control the mass flow at the hot ends of regenerator and pulse tube. Because the size of pulse tube is an important parameter of the cryocooler, three kinds of pulse tube, 18, 28 and 38 mm in diameter, were prepared for investigating the influence of pulse tube size on cooling performance. Initial test demonstrated that the cryocooler with the pulse tube of 28 mm in diameter delivers a cooling power of 33.5 W at 80 K. Cycle frequency also shows a great effect on cooling performance, and the cryocooler reached its terminal temperature of 20.5 K with a cycle frequency of 1.8 Hz. This paper describes details of the cryocooler design and the experimental results.
