Abstract

The invention discloses a diaphragm compression type linear compressor system for a high-frequency pulse tube refrigerator. The diaphragm compression type linear compressor system comprises a coil, a magnet, an upper yoke, a lower yoke, a push rod, a diaphragm, an upper plate spring, a lower plate spring, a plate spring supporting frame, an air cylinder and a shell. The push rod, the diaphragm, the lower plate spring, the coil and the upper plate spring are fixed through the locking nut, the coil in the magnetic field drives the push rod, the upper plate spring, the lower plate spring and the diaphragm to vibrate after being connected with alternating current, gas in the air cylinder is periodically compressed and expanded, alternating oscillating flow is formed, and the cold finger of the high-frequency pulse tube refrigerator can be driven. According to the diaphragm compression type linear compressor system for the high-frequency pulse tube refrigerating machine, the problem of extremely high-precision machining and assembling of the piston and the air cylinder in a clearance sealing technology in a linear compressor can be solved, and the cost and the overall machining and assembling difficulty are reduced on the premise that high reliability is guaranteed; and the high-frequency pulse tube refrigerating machine has very positive significance in marketization application of the high-frequency pulse tube refrigerating machine.

Description

technical field [0001] The invention relates to the technical field of refrigeration and low temperature engineering, relates to a compressor system for a pulse tube refrigerator, in particular to a diaphragm compression type linear compressor system for a high frequency pulse tube refrigerator. Background technique [0002] The pulse tube refrigerator is a major innovation of the regenerative low temperature refrigerator. Compared with the conventional regenerative low temperature refrigerator, it cancels the moving parts in the low temperature area of ​​the refrigerator, and realizes the compression of the cold end gas through the gas piston in the pulse tube. and expansion process, low vibration, low interference and no wear at the cold end are achieved; and after structural optimization and important improvements in phase modulation methods, in typical temperature regions, its actual efficiency has reached the highest value of regenerative cryogenic refrigerators. . The...
