Abstract
This chapter focuses on the application possibility of the pulse tube refrigerator under large mass flow rate. A type of cryocooler named large diameter pulse tube refrigerator is suggested. With gas expansion analysis and control volume analysis, theoretical analysis has been carried on and verified by experiments. The results show that some parameters such as working frequency and inlet gas pressure have significant influence on the large diameter pulse tube working conditions. The main purpose of this chapter is to solve the problem that small diameter pulse tube (common) generates less refrigeration power. At present, the diameter of pulse tube ranges from 3mm to 9mm , and its principles of refrigeration are fully discussed in the chapter. Similar to the small diameter one, the large diameter pulse tube has the same inlet-outlet types such as shift type (basic type) and reversible type, and the same hot-end improved models as reservoir-orifice structure and double inlet structure. The analysis methods of common pulse tube are manifold. So it is possible to discuss the mechanism of large diameter pulse tube refrigerator on the basis of the theory of small diameter one. Therefore the aim of this research is to deliberate the pulse tube refrigerator's principle all-roundly.
