VACUUM ADIABATIC BODY AND REFRIGERATOR

WIPO Patent Application WO/2021/139267

A1

A vacuum adiabatic body (100) and a refrigerator having the vacuum adiabatic body (100). The vacuum adiabatic body (100) comprises: a first plate (101), the first plate (101) having a first thickness; a second plate (102) spaced apart from the first plate (101) in an opposite manner, the second plate (102) having a second thickness, and the first thickness being greater than the second thickness; and sealing pieces (103) arranged between the first plate (101) and the second plate (102) and configured to seal and fix the first plate (101) and the second plate (102), a vacuum cavity (110) being defined among the first plate (101), the second plate (102), and the sealing pieces (103). According to the vacuum adiabatic body (100), convection heat transfer can be reduced by vacuumizing between two plates which are sealingly connected; the first plate (101) has the first thickness, the second plate (102) has the second thickness, and the first thickness is greater than the second thickness, so that the whole vacuum insulation body (100) is stable in structure and not too heavy.
