Abstract

A vacuum adiabatic body includes a first plate, a second plate, and a seal for sealing the first plate and the second plate to provide a vacuum space. Optionally, the vacuum adiabatic body includes a side plate extending in a height direction of the vacuum space. Optionally, the vacuum adiabatic body includes a supporter for maintaining the vacuum space. Optionally, the vacuum adiabatic body includes a heat transfer resistor for reducing heat transfer between the first plate and the second plate. Optionally, the vacuum adiabatic body includes a component coupler connected to at least one of the first and second plates and to which a component is coupled. Optionally, the second plate and the side plate are provided as one body by a single body. Thus, the productivity of the vacuum adiabatic body is improved.

Dependent claims

A vacuum adiabatic body comprising:

a first plate;
a second plate spaced apart from the first plate to form a vacuum space in a height direction of the vacuum space between the first plate and the second plate;
and
a side plate configured to define a side of the vacuum space,
wherein the first plate, the second plate, and the side plate include a plurality of straight portions;
wherein one of the plurality of straight portions includes a first section closer to a center of the vacuum adiabatic body than a second section which is closer to an edge of the vacuum adiabatic body than the first section, and the first section of the one of the plurality of straight portions is thinner than the second section of the one of the plurality of straight portions, and
wherein the one of the plurality of straight portions includes a third section of a third thickness in a corner section of a surface perpendicular to the height direction and a fourth section of a fourth thickness in a non-corner section of the surface, the third thickness being smaller than the fourth thickness.
