HEAT INSULATION STRUCTURE AND CRYOGENIC LIQUID STORAGE TANK HAVING THE SAME

摘要

PURPOSE: An insulation structure and a cryogenic liquid storage tank having the same are provided to obtain excellent resistance to the pressure of a cryogenic liquid by being inserted into a receiving groove which is formed on an insulating panel. CONSTITUTION: An insulation structure(11) of a cryogenic liquid storage tank is combined with the inner side of a tank wall(10) of the cryogenic liquid storage tank. The insulation structure insulates a storage space in which a cryogenic liquid is stored. The insulation structure comprises: an insulating panel(12) which is combined with the tank wall to prevent thermal transfer between the tank wall and the storage space and includes a plurality of receiving grooves(23); and a main barrier(13) having a plurality of wrinkles parts(26) which are inserted into the multiple receiving grooves.
