VACUUM ADIABATIC BODY AND REFRIGERATOR

Title:

VACUUM ADIABATIC BODY AND REFRIGERATOR

Document Type and Number:

WIPO Patent Application WO/2017/023076

Kind Code:

A1

Abstract:

A vacuum adiabatic body includes: a first plate member defining at least one portion of a wall for a first space; a second plate member defining at least one portion of a wall for a second space having a different temperature from the first space; a sealing part sealing the first plate member and the second plate member to provide a third space that has a temperature between the temperature of the first space and the temperature of the second space and is in a vacuum state; a supporting unit maintaining the third space; a heat resistance unit at least including a conductive resistance sheet capable of resisting heat conduction flowing along a wall for the third space to decrease a heat transfer amount between the first plate member and the second plate member; and an exhaust port through which a gas in the third space is exhausted, wherein the supporting unit includes at least two bars supporting the first plate member and the second plate member, the bar includes a material having a lower emissivity than each of the first and second plate members, and the bar is fabricated using at least one material selected from the group consisting of polycarbonate (PC), glass fiber PC, low outgassing PC, polyphenylene sulfide (PPS), and liquid crystal polymer (LCP).
