VACUUM ADIABATIC HOUSING AND REFRIGERATOR Russian patent published in 2021 - IPC F25D23/06 F25D11/00 

FIELD: refrigeration equipment.

SUBSTANCE: invention relates to refrigeration equipment. The refrigerator contains a vacuum adiabatic housing, which includes a first plate that forms at least a wall section for the first region having the first temperature, a second plate that forms at least a wall section for the second region having the second temperature. The sealing part seals the first plate with the second plate to form a third region, which has a third temperature and is in a vacuum state. The refrigerator also includes a support unit in the third area and an opening that is formed relative to the storage area; a partition that divides the storage area into at least two areas. The partition includes an adiabatic element to isolate the mentioned at least two areas. The first door serves to open and close the first area of the mentioned at least two areas. The second door serves to open and close the second area of the mentioned at least two areas. The evaporator is located in the storage area. The engine compartment is located on the outside of the storage area. The refrigerant coolant pipe connects the engine compartment and the evaporator. The drain pipe passes through the vacuum adiabatic housing to direct the melt water from the evaporator to the outside of the vacuum adiabatic housing. The heat transfer rate of the adiabatic element in the partition is higher than the heat transfer rate in the third region. At least one of the meltwater channels and the electrical conduit channel pass through the third area. Through holes for pipelines are formed on the first plate and the second plate. A channel for cold air flow is formed through a partition to direct and receive cold air between the first region and the second region of the at least two regions mentioned.

EFFECT: invention makes it possible to increase the strength of the vacuum adiabatic housing.
