HEAT-INSULATING WALL, AS WELL AS REFRIGERATOR AND DOMESTIC OVEN WITH SUCH WALLS Russian patent published in 2005 - IPC

FIELD: heat vacuum insulation, for example, in refrigerators or domestic ovens.

SUBSTANCE: the heat-insulating wall has two external vacuum-tight layers. They are positioned at a distance from each other and vacuum-tightly connected with the aid of a connecting profile passing along then. The space between the walls and the profile is filled with vacuumized heat-insulating material. The profile consists of several sections. In annular zones of the heat-insulating wall the sections of the connecting profile are made integral. The profile may have a U-shaped cross-section. The elements of the profile sections are interconnected by welding.

EFFECT: provided leak-proofness of vacuum insulation due to absence of a joint point and piling of welded joints in angular zones; provided required profile geometry determined by functional-technical considerations, since the angular sections are preliminary manufactured parts.
