VACUUM ADIABATIC BODY AND REFRIGERATOR Russian patent published in 2022 - IPC F25D23/06 

FIELD: cooling.

SUBSTANCE: invention relates to a vacuum adiabatic body and a refrigerator. The refrigerator comprises a main body provided with a vacuum adiabatic body and an internal space configured to accommodate objects, a door configured to open or close the main body in order to provide access to the internal space from the external space, a compressor configured to compress the refrigerating agent, a condenser configured to condense the compressed refrigerating agent, an expansion apparatus configured to expand the condensed refrigerating agent, an evaporator configured to evaporate the expanded refrigerating agent in order to dissipate heat. The heat exchange pipeline has an intake pipeline and an outlet pipeline, interconnected. The refrigerating agent is released from the evaporator through the exhaust pipe. The refrigerating agent flows into the evaporator through the intake pipeline. The vacuum adiabatic body includes: a first plate configured to form at least a wall segment for the internal space; a second plate configured to form at least a wall segment for the external space; a third space provided between the first and second plates and configured to be a vacuum space; a support configured to maintain the distance between the first and second plates; a hole formed through at least one of the first plate and the second plate. A segment of the heat exchange pipeline is provided in the third space. A section of the heat exchange pipeline passes through the hole. A tube surrounds the inlet pipe and the outlet pipe, connected with at least one of the first plate or the second plate.

EFFECT: invention contributes to reduction in the heat losses, reduction in the possibility of vacuum failure, and reliability of the inlet and outlet pipelines.
