Description
Invention field
The invention belongs to refrigeration and cryogenic technique field, particularly a kind of method of using two-stage coaxial pulse tube refrigerating machine cooling high-temperature superconducting filtering device.
Background technology
The high-temperature superconductor mobile communication base site sub-system, be to refer in particular to the electronics subsystem of forming by high-temperature superconductor microwave device and small-sized Cryo Refrigerator, be used for replacing the critical component of existing mobile communication base station receiver front end, as filter and low noise pre-amplifier etc.The main order that adopts small-sized Cryo Refrigerator cooling high-temperature superconducting mobile communication base site sub-system is in order to reduce equipment size, to improve the combination property of receiver, as the raising selectivity, and sensitivity, speech quality reduces power loss, and widens coverage rate etc.In order to reduce the electromagnetic interference of out-of-band noise, improve speech quality, high temperature superconduction wave filter spare usually and the low noise pre-amplifier integrate use.High-temperature superconductor (generally be YBCO, employing TBCCO is also arranged) filter is a passive device, and it must be cooled to below the superconducting transition temperature (normally 65～80K, promptly subzero 208～193 ℃), could operate as normal.Filter links to each other with the low noise pre-amplifier by one group of coaxial cable usually.The low noise pre-amplifier is an initiatively device, and it can produce the heat load of hundreds of milliwatt; On the other hand, the low noise pre-amplifier links to each other with vacuum tank by one group of coaxial cable, and this group coaxial cable also can produce the heat load of hundreds of milliwatt; The 3rd heat load derives from the thermal radiation on refrigeration machine and vacuum tank surface, estimates the magnitude that it also has the hundreds of milliwatt.When the low noise pre-amplifier was cooled to 90～110K (being subzero 183～163 ℃), its signal to noise ratio can significantly be improved.
The extensive use of high temperature superconduction wave filter spare depends on the development of cryogenic system.In recent years, progress along with large area high temperature superconductive thin film fabrication technology, the design of high-performance high-temperature superconductor passive device, manufacturing technology, mobile communication is at an unprecedented rate developing with scale, formed huge industry, its further development presses for adopts mechanical type refrigerating method cooling high-temperature superconducting filtering device.Adopt the mechanical type refrigerating method can strengthen the mobile communication base station antijamming capability, enlarge the base station area coverage, strengthen the base station capacity, can also reduce the transmitting power of base station and mobile phone.
Use the mechanical refrigeration method rather than high temperature superconduction wave filter spare directly is immersed in the cryogenic liquid, be a research emphasis in low temperature field always.At present, abroad be to adopt the low temperature cold source of sterlin refrigerator basically as high temperature superconduction wave filter spare.But because the existence of mechanical moving elements such as stirling-type refrigeration machine cold head displacer, mechanical oscillation that they bring and electromagnetic interference signal have a significant impact the operate as normal output signal of high temperature superconduction wave filter spare.Compare with sterlin refrigerator, the cold head of pulse tube refrigerating machine does not have mechanical moving element, thereby mechanical realization is simple, and vibration and electromagnetic interference are little, are the desirable low-temperature receivers that is suitable for high temperature superconduction wave filter spare.Chinese patent CN 1074525C " a kind of coaxial type pulse tube refrigerating machine " discloses a kind of single-stage coaxial impulse pipe refrigerating machine with characteristics such as efficient, compact conformation.But do not relate to coaxial impulse pipe refrigerating machine and the connected mode between the device of being cooled.
Adopt the low temperature cold source of single-stage coaxial impulse pipe refrigerating machine as high temperature superconduction wave filter spare, normally high temperature superconduction wave filter spare is installed on the cold head of single-stage coaxial impulse pipe refrigerating machine with the prime low noise amplifier that links to each other with it by coaxial cable, and is placed in the protective shield of radiation that is installed on the cold head with high reflectance.This cooling means is simple in structure, in light weight, easy to operate.But, because high temperature superconduction wave filter, low noise amplifier and protective shield of radiation are installed on the cold head, needing bigger refrigerating capacity, power consumption is bigger as a result, and the refrigeration machine load is bigger, and temperature fall time is longer.Because the working temperature of high temperature superconduction wave filter needs, the cold head of refrigeration machine must operate at the cryogenic temperature of 65K, but low noise amplifier and protective shield of radiation normal working temperature scope are 90-110K, so we have proposed another kind of special two-stage coaxial pulse tube refrigerating machine structure, are used for cooling high-temperature superconducting filtering device and prime low noise amplifier.
