Description
Technical field
The present invention relates to adiabator field, particularly to the heat shield structure of the chiller of a kind of low temperature superconducting field.
Background technology
General metal material, in the temperature range of absolute zero, along with the decline of temperature, its resistivity levels off to a limited constant.Some simple metal, alloy and compound etc. are near a certain specific temperature Tc, and resistance suddenly disappears, and this phenomenon is superconductivity, and the material with this performance is called superconductor.In general, the object at about 4.2K with superconductivity is called cryogenic superconductor, and under liquid nitrogen temperature, (77K) has the object of superconductivity and be called high-temperature superconductor.
Low-temperature superconducting wire and band are mainly applied under liquid helium temperature (4.2K).Utilize the various characteristics of superconductor, as resistance suddenly disappears, perfect diamganetism, can bear the change of physical property when occurring superconducting state to change to normal state of very big supercurrent and superconductor in high-intensity magnetic field, low-temperature superconducting wire strip has started to be applied in many science and technology field, and demonstrates prominent advantage and bright prospects.

At present, the low temperature environment of the cryogenic magnetic field of controlled nuclear fusion supports that system can adopt liquid helium to cool down, low temperature environment supports that the equipment that system is mainly cryogenic magnetic field is maintained in required low temperature environment, and it includes chiller and is wrapped in the multiple layer heat insulation structure of chiller.Adiabator is usually composited by low-temperature thermal insulation paper and radiation shield (aluminium foil or metallized film), and low-temperature thermal insulation paper and radiation shield storeroom are every setting.Multiple layer heat insulation structure outside general chiller is repeatedly wrapped up by low-temperature thermal insulation paper and radiation shield and is formed, and be fixed by cellotape, this parcel mode complicated operation, easily cause parcel imprecision, effect of heat insulation is poor, and outside chiller, have a lot of connector and maintenance storehouse, not easily on heat insulating construction, carrying out opening.
