Description
technical field [0001] The invention belongs to the field of refrigeration and low-temperature engineering, and relates to a pulse tube refrigerator, in particular to a compactly coupled inertial tube type high-frequency U-shaped pulse tube refrigerator and a manufacturing method. Background technique [0002] The pulse tube refrigerator is a major innovation of regenerative cryogenic refrigerators. It cancels the cold-end ejector widely used in conventional regenerative cryogenic refrigerators (such as Stirling and G-M refrigerators), and realizes cold Low vibration, low interference and no wear at the end; and after structural optimization and important improvements in phase adjustment methods, its actual efficiency has reached the highest value of regenerative cryogenic refrigerators in typical temperature ranges. These remarkable advantages make the pulse tube refrigerator a hot spot in the research of cryogenic refrigerators in the past 30 years, and have been widely us...
