Description

Technical Field

[0001] The utility model relates to the technical field of low-temperature thermostats, in particular to a superconducting module low-temperature thermostat. Background Art

[0002] A cryostat uses a refrigeration system to cool its internal environment to extremely low temperatures, typically within a few degrees Kelvin or even lower. This low temperature allows the superconducting material in the superconducting module to achieve a superconducting state, enabling unique properties such as resistance-free electrical conduction. This refrigeration system typically uses a cryogenic medium such as liquid nitrogen or liquid helium, or utilizes mechanical refrigeration to achieve the low temperature.

[0003] The patent document with the published announcement number CN219421341U discloses a superconducting module cryostat, comprising a main body, a closed door provided on the main body, a controller provided on the main body, a base provided at the bottom of the main body, a cryostat chamber provided in the main body, a mounting plate provided inside the bottom end of the main body, a cryostat assembly provided on the mounting plate, a partition provided on the main body, a temperature-insulating element used in the partition, a top tightening element provided on the temperature-insulating element, and support mechanisms provided on both sides of the top tightening element. The utility model comprises a partition, a temperature-insulating element, a top tightening element, a support mechanism, a rubber sealing ring, and a top tightening spring. Due to the increase in use time, the elasticity of the rubber sealing ring decreases. The top tightening spring can also ensure the sealing effect of the rubber sealing ring. The temperature-insulating element in the partition will preferentially block the transfer of temperature. At the same time, the vacuum state of the partition can further enhance the temperature-insulating effect. When the external temperature acts on the main body, a blocking effect will also be produced, further improving the temperature-insulating effect of the device.

[0004] When the above device is in use, it ensures the sealing effect of the rubber sealing ring and also improves the thermal insulation effect of the equipment. However, in actual use, directly placing superconducting magnets, superconducting quantum bits and experimental samples in the low-temperature constant temperature chamber will cause the placed items to be messy and limited. At the same time, experiments such as material science research need to be carried out, and a bracket may be placed separately to fix and support the experimental samples. If the bracket is placed directly in the low-temperature constant temperature chamber, it may shake and be unstable, and may also interfere with the situation inside the low-temperature constant temperature chamber.
