Abstract
A vacuum adiabatic body and a refrigerator are provided. The vacuum adiabatic body includes a support. The support includes a main support having a two-dimensional planar structure and crossing a space, and a first bar and a second bar, which respectively extend from both sides of the main support toward a first plate and a second plate, respectively.
Claims17
A vacuum adiabatic body, comprising:
- a first plate defining at least a portion of a wall for a first space;
- a second plate defining at least a portion of a wall for a second space having a second temperature different from a first temperature of the first space;
- a sealing that seals the first plate and the second plate to provide a third space having a third temperature between the first temperature and the second temperature, wherein the third space is a vacuum space;
- a support that maintains the third space;
- a heat resistance unit that reduces a heat transfer amount between the first plate and the second plate, the heat resistance unit comprising at least one radiation resistance sheet disposed in the third space;
- and
- an exhaust port through which a gas of the third space is exhausted, wherein the support comprises:
- a main support having a two-dimensional planar structure and crossing the third space;
- and
- at least one first bar and at least one second bar, which respectively extend from both sides of the main support toward the first plate and the second plate, respectively, wherein the at least one radiation resistance sheet comprises an opening into which the at least one first bar and at least one second bar is inserted, and wherein an inner edge of the opening comprises a support piece configured to contact the at least one first bar and at least one second bar and a groove positioned adjacent to the support piece to allow the support piece to be bent.

A refrigerator, comprising:
- a main body providing an internal space in which goods are stored;
- a door configured to open and close the internal space;
- a refrigeration cycle that supplies cold air to the internal space, the refrigeration cycle comprising:
- a compressor that compresses a refrigerant;
- a condenser that condenses the compressed refrigerant;
- an expansion valve that expands the condensed refrigerant;
- and
- an evaporator that evaporates the expanded refrigerant to dissipate heat, wherein the door or the main body comprises a vacuum adiabatic body, and wherein the vacuum adiabatic body comprises:
- a first plate defining at least a portion of a wall for a first space;
- a second plate defining at least a portion of a wall for a second space having a second temperature different from a first temperature of the first space;
- a sealing that seals the first plate and the second plate to provide a third space having a third temperature between the first temperature and the second temperature, wherein the third space is a vacuum space;
- an exhaust port through which a gas within the third space is exhausted;
- at least one radiation resistance sheet that reduces radiation heat transfer between the first plate and the second plate;
- and
- a support comprising
- a main support disposed in an inner space of the third space and provided as a two-dimensional planar structure, the main support including a first surface that faces the first plate and a second surface that faces the second plate;
- at least one first bar that extends from the main support toward the first plate;
- and
- at least one second bar that extends from the main support toward the second plate, wherein the at least one radiation resistance sheet comprises a first sheet provided on the first surface of the main support and a second sheet provided on the second surface of the main support, and wherein at least one of the first sheet or the second sheet includes a sheet base attached to the main support and a sheet protrusion configured to protrude from the sheet base and having a bent end to contact the one of the first plate or the second plate.
