Résumé

Vacuum-pumping is one of the important procedures for the technical process of manufacturing cryogenic cylinders, and a so-called "internal heating" method is widely employed during the vacuum-pumping process. In this study, the distribution of temperature in the insulating materials during the process of vacuum-pumping is experimentally investigated, using thermocouples fixed in the materials. Temperature distributions are tested under the static and dynamic conditions, respectively. It is found that the temperature gradient under the dynamic condition is much larger than that under the static condition, and can become steady more rapidly. This conclusion indicates that inner heating is more effective for vacuum-pumping.
