Description
Technical field
Technical field of the invention is related to refrigeration ＆ cryogenic engineering field, superconduction engineering field and communication engineering field, relates to
And pulse tube refrigerating machine and high temperature superconduction wave filter, more particularly to a kind of straight pulse control cold cooling high-temperature superconducting wave filter
Structure and manufacture method.
Background technology
High temperature superconductor technology is applied to moving communicating field as one of swift and violent cutting edge technology is developed in recent years, has
The high temperature superconduction wave filter that many advantages, particularly high temperature superconducting materia are made, compared with conventional wave filter, the loss of its passband
Small, stopband suppresses big, sideband is precipitous, can be made into narrow-band filter, small volume, light weight.It is applied to civilian mobile communication neck
Domain, high temperature superconduction wave filter is remarkably improved selectivity, sensitivity and information transfer rate, the raising call matter of mobile base station
Amount, increase traffic capacity, expansion base station area coverage, enhancing base station antijamming capability, reduction mobile phone transmission power.With high temperature
Theoretical and manufacturing process the maturation of super conductive filter, and the fast development in the world of mobile communication industry, high-temperature superconductor
Wave filter is expected to bring revolutionary change for global mobile communication field.
Mobile base station high temperature superconduction wave filter best effort environment temperature is 60~80K, small-sized low at present in this warm area
Warm mechanical refrigerator be can be very good to meet high temperature superconduction wave filter cold requirement as low-temperature receiver, it is contemplated that high-temperature superconductor is filtered
The external working environment of device, except cold requirement is outer, in addition it is also necessary to refrigeration machine with stable, efficient, low interference, the long-life, small size,
The features such as light weight.At present, domestic and international mobile base station high temperature superconduction wave filter product uses sterlin refrigerator conduct mostly
Low temperature cold source, but because the moving components such as sterlin refrigerator cold head end displacer can bring mechanical oscillation and electromagnetic interference to believe
Number, there is considerable influence to the work output signal of high temperature superconduction wave filter.And the reliability of sterlin refrigerator and work longevity
Life is also a larger bottleneck for influenceing its service behaviour.
Pulse tube refrigerating machine comes into operation after the eighties in 20th century, is to the once great of regenerating type low-temperature refrigerator
Innovation, compared with other small-sized regenerating type low-temperature refrigerators especially sterlin refrigerator, it eliminates cold end displacer, phase
Regulation is completed by passive phase modulating mechanism, therefore in cold end movement-less part, realizes cold end low vibration, low interference and without mill
Damage, and by the improvement on phase modulation frame mode, in some typical warm areas, its efficiency has been reached in regenerating type low-temperature refrigerator
Peak.Therefore, pulse tube refrigerating machine has that cold big, the vibration of efficiency high, cold end mechanical, reliability be high, life expectancy
Long many advantages, such as.

Internal gas working medium needs to be turned back 180 degree in cold end, causes larger drag losses and flow perturbation；It is U-shaped arrangement equally have compared with
Big irreversible loss.
As shown in figure 1, linear pattern arrangement air-flow need not turn back, gas flow resistance can be to greatest extent reduced,
The efficiency highest in three kinds of arrangements.In 60~80K warm areas, the refrigerating capacity of linear pattern pulse tube refrigerating machine can meet height
The potential demand of temperature superconductive wave filter High cooling power, but the disadvantage of linear pattern arrangement is its coupling with high temperature superconduction wave filter
There is certain difficulty in conjunction, as can be seen from Figure 1, the cold end of linear pattern arrangement is located between regenerator 3 and pulse tube 4, cold finger entirety
It is more long so that the more difficult extraction and application of cold.Accordingly, it would be desirable to make the best use of the advantages keeping away to the advantage and disadvantage of single-stage linear pattern arteries and veins portion's control cold
It is short, it is can be used for the cooling of high temperature superconduction wave filter.
