| Abstract: | For the favorable heat insulation performance, the heat transfer of cylinder full of cryogenic liquid was analyzed by finite element analysis method and the calculation results conformed to the results of experiments. The heat leak through neck tube, supports and insulated structure of cylinders were also obtained to achieve an optimum design for the structure of products. |
