The invention discloses high-temperature superconductor refrigerating equipment based on fixed nitrogen. The high-temperature superconductor refrigerating equipment comprises a refrigerating motor and a refrigerating machine body. The refrigerating machine body comprises a cold head, a vacuumizing device and a heat preservation device. The refrigerating motor, the vacuumizing device and the heat preservation device are sequentially arranged from top to bottom. The vacuumizing device is connected with the heat preservation device. The first end of the cold head is connected with the refrigerating motor. The second end of the cold head extends into the vacuumizing device and is connected with a cold guide wire with one end extending into the heat preservation device. A high-temperature superconductor is arranged in the heat preservation device. The periphery of the high-temperature superconductor is filled with fixed nitrogen. The temperature in the heat preservation device can be lowered under the action of both the vacuumizing device and the refrigerating motor, and refrigerating is finished. After refrigerating is finished, a great amount of heat of the high-temperature superconductor can be absorbed by the adoption of the high heat capacity of fixed nitrogen in the heat preservation device so that the temperature of the high-temperature superconductor can be lowered, and normal working of the high-temperature super conductor is guaranteed. The high-temperature superconductor refrigerating equipment is good in refrigerating effect and heat preservation effect, low in cost, convenient to operate and high in applicability.
Description
technical field [0001] The invention relates to the technical field of refrigeration devices, in particular to a high-temperature superconducting refrigeration equipment based on nitrogen fixation. Background technique [0002] The phenomenon of superconductivity refers to the phenomenon that when the temperature drops to a certain level, the resistance of the metal will suddenly disappear and become zero. Materials with such a critical temperature are called high-temperature superconductors. The discovery and application of high-temperature superconductivity have very prominent advantages and irreplaceable roles in many fields. However, since the application of high-temperature superconductors requires the application of high-temperature superconductors in an environment close to absolute zero, the application of high-temperature superconductors will encounter the problem of refrigeration. [0003] Traditional high-temperature superconductor refrigeration technology genera...
