Claim Text:
1. A structure of a vacuum insulator configured to increase a thermal insulation performance of the vacuum insulator, the structure comprising: a top board; a bottom board; and an assembly reciprocating support comprising a solid shaft, a hollow shaft, and a connection part between the top board and the bottom board; wherein in the structure of the vacuum insulator, a material of the vacuum insulator is determined based on a figure of merit, and the figure of merit is proportional to a yield strength of the material and inversely proportional to a thermal conductivity coefficient; and wherein the material of the vacuum insulator comprises polycarbonate used for the top board, the bottom board, the solid shaft, and the hollow shaft, and stainless steel used for the connection part.
