Abstract
A vacuum adiabatic body and a refrigerator are provided. The vacuum adiabatic body includes a support that maintains a vacuum space between a first plate and a second plate, and a heat resistance unit comprising at least one radiation resistance sheet that blocks radiation heat transfer in the vacuum space so as to reduce heat transfer between the first plate and the second plate. The support includes two support plates, and the at least one radiation resistance sheet is supported by at least one support protrusion provided on a bar, which couples the two support plates to each other, to maintain an interval between the first plate and the second plate.
Claims18
A vacuum adiabatic body, comprising:
- a first plate;
- a second plate;
- a vacuum space provided between the first plate and the second plate;
- and
- a support configured to maintain a distance between the first plate and second plate;
- and
- a radiation resistance sheet to reduce heat radiation between the first plate and second plate, wherein the support includes at least one bar that extends in a direction between the first plate and second plate, a first support plate that extends in a direction in which the first plate extends and a second support plate that extends in a direction in which the second plate extends, and wherein the at least one bar includes:
- a first portion that extends from the first support plate;
- and
- a second portion that extends from the second support plate and is coupled to the first portion, and wherein a length of the first portion protruding from the first support plate is greater than a length of the second portion protruding from the second support plate.
A vacuum adiabatic body, comprising:
- a first plate;
- a second plate;
- a vacuum space provided between the first plate and the second plate;
- a support configured to maintain a distance between the first plate and second plate;
- and
- a radiation resistance sheet to reduce heat radiation between the first plate and second plate, wherein the support includes at least one bar that extends in a first direction between the first plate and second plate, and wherein the at least one bar includes:
- a first portion that extends in the first direction which is different from a second direction in which the first plate extends;
- and
- a second portion provided as a component separate from the first portion and including a support groove in which the first portion is supported, wherein the first portion includes a first column received in the support groove and a second column provided outside of the support groove, and wherein a length of the second column is more than twice a length of the first column.
A vacuum adiabatic body, comprising:
- a first plate;
- a second plate;
- a vacuum space provided between the first plate and the second plate;
- a support configured to maintain a distance between the first plate and second plate;
- and
- a radiation resistance sheet to reduce heat radiation between the first plate and second plate, wherein the support includes at least one bar that extends in a first direction between the first plate and second plate, and wherein the at least one bar includes:
- a first portion that extends in the first direction which is different from a second direction in which the first plate extends;
- and
- a second portion provided as a component separate from the first portion and including a column having an accommodation portion in which the first portion is supported, wherein the second portion includes an inner circumferential surface having a first part that contacts the first portion and a second part spaced apart from the first portion.
