Abstract

The invention discloses a compact coupled inertance tube type high-frequency coaxial pulse tube refrigerator and a manufacturing method thereof. The refrigerator is composed of a main base, an auxiliary base, a special-shaped compressor base, opposed linear-compressor main components, a left compressor shell, a right compressor shell, a compressor connecting tube, a main heat exchanger, an auxiliary heat exchanger, a regenerator, a pulse tube, a cold-end heat exchanger, a vacuum housing, a pulse tube connecting tube, an inertance tube, an air reservoir and a protective housing. Structural features of a coaxial pulse tube refrigerator, an inertance tube phase modulation device and a linear compressor can be given into full play, compactness and high reliability of an overall system are realized, and it is of important significance to practicability of the coaxial pulse tube refrigerator in the special fields such as aerospace.

Description

technical field [0001] The invention belongs to the field of refrigeration and cryogenic engineering, and relates to a pulse tube refrigerator, in particular to a compactly coupled inertial tube type high-frequency coaxial 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 used in a...
