VACUUM INSULATOR IN A STOREHOUSE AND METHODS OF MAKING AND USING THE SAME

A vacuum insulator including a heat diffusion block placed in a vacuum space; a thermoelectric module, in the vacuum space, coming into contact with the heat diffusion block so as to exchange heat therewith: and a heat sink exchanging heat with the thermoelectric module and placed in a first space or a second place. High heat-insulation performance and heat-transfer performance can be obtained.
