摘要： A vacuum adiabatic body includes a first plate configured to define at least a portion of a wall for a first space, a second plate configured to define at least a portion of a wall for a second space having a temperature different from that of the first space, and a support configured to maintain the third space. The support includes a coupling mechanism by which a first support plate and a second support plate are coupled to each other and integrated with each other and a seating mechanism configured to maintain a gap between the first support plate and the second support plate at points at which the first support plate and the second support plate contact each other. The seating mechanisms are spaced apart from the coupling mechanism.

摘要： A vacuum adiabatic body includes a heat exchange pipeline and a sealing plug. The heat exchange pipeline includes at least two pipelines which pass through a first plate and a second plate to allow a refrigerant to move between inner and outer spaces. The sealing plug allows the heat exchange pipeline to pass through a first point of the first plate and a second point of the second plate without contacting a third space.
