Description
Technical field
The present invention relates to regenerating type low-temperature refrigerator, relate in particular to the multistage Cryo Refrigerator of a kind of two-stage Stirling and single-stage pulse tube gas coupled cascade.
Background technology
Compare with sterlin refrigerator with G-M refrigeration machine, Bretton refrigeration machine, vascular refrigerator does not have moving component at cold junction, have the advantages such as simple in structure, that cost is low, mechanical oscillation are little, reliability is high and the life-span is long, this is so that vascular refrigerator becomes current study hotspot.Vascular refrigerator can be divided into low frequency vascular refrigerator and high-frequency vascular refrigerator according to operating frequency, wherein high-frequency vascular refrigerator is because volume is little, lightweight, the advantages such as efficient is high, compact conformation become the ideal chose that the long-life Cryo Refrigerator is used in the space, thereby paid close attention to widely.The part optics in the fields such as while Aero-Space and the operating temperature of instrument are generally in 4K or lower temperature, this is so that the research of liquid helium warm area high-frequency vascular refrigerator becomes focus, but because refrigeration mechanism and the loss mechanism of liquid helium warm area still lack comprehensive grasp, also there are a lot of difficulties so that adopt merely the high-frequency vascular refrigerator structure to arrive liquid helium temperature, only have at present U.S. LockheedMartin company to use quaternary structure to arrive the liquid helium warm area, but complex structure, efficient is low.And adopt tertiary structure also not reach the report of liquid helium warm area.
Sterlin refrigerator and vascular refrigerator belong to philip refrigerator together, its theoretical efficiency equals Carnot efficiency, efficient than the vascular refrigerator that does not reclaim expansion work is high, and the development of Oxford flat spring support technology and Gap Sealing Technology, so that moving back and forth, the piston in the compressor, the displacer in the decompressor and the noncontact between the cylinder become possibility, successfully solved the difficult problem of sterlin refrigerator long-life operation, so sterlin refrigerator has, and efficient is high, the little and long-life advantage of vibration.At present existing many sterlin refrigerators are applied in the field of space technology of 80K and 35K.But, further reduction along with cryogenic temperature, the expansion chamber displacer becomes long in the multi-stage stirling refrigeration machine, is difficult to guarantee that the noncontact between low-temperature end displacer and the cylinder moves back and forth, and this is so that space long-life sterlin refrigerator arrives the liquid helium warm area has difficulties.At present, the cryogenic temperature of existing three grades of sterlin refrigerators there is no method and arrives the liquid helium warm area.
The numerical simulation result of pre-cold mould single-stage high-frequency vascular refrigerator shows: if will make the cold junction temperature of high-frequency vascular refrigerator reach liquid helium temperature, its hot-side temperature significantly improves along with the raising of cold junction pressure ratio.When using He-4 as working medium, cold junction pressure ratio (P
Max/ P
Min) be 1.4 o'clock, at specific dimensions, under regenerative material and the lower the blowing pressure condition (being generally 0.5-1.0MPa), the hot-side temperature of 4K high-frequency vascular refrigerator is near 40K, and the lowest refrigerating temperature of existing two-stage Stirling refrigeration machine and secondary high-frequency vascular refrigerator is far below this temperature, but the blowing pressure is higher during owing to the high-frequency vascular refrigerator operation, the pressure loss in regenerator is larger, (single-stage generally reaches 1.20-1.25 can't to obtain large pressure ratio at cold junction, secondary is generally at 1.15-1.20) so that three grades of high-frequency vascular refrigerators are difficult to reach the liquid helium warm area.Point out and analyze: the viscosity of helium significantly reduces along with the reduction of temperature, it is the high temperature section that the pressure loss of regenerator mainly occurs in 300-80K, owing to having active control assembly---displacer in the sterlin refrigerator, so that the cold junction pressure ratio of its adjustable joint refrigeration machine, so that adopts two-stage Stirling refrigeration machine and single-stage high-frequency vascular refrigerator composite structuredly can realize high pressure ratio that liquid helium warm area high-frequency vascular refrigerator low-temperature zone is required and little the blowing pressure, namely adopting the composite structured of two-stage Stirling refrigeration machine and single-stage high-frequency vascular refrigerator is to arrive the liquid helium warm area in theory, and has both compact conformations concurrently, efficient is high, the advantage such as long-life and high reliability.
