SOIL HEAT STABILIZER Russian patent published in 2016 - IPC E02D3/115 

FIELD: building construction.

SUBSTANCE: invention relates to building construction in zones of perpetual congelation, particularly to soil heat stabilizers which serve to freeze foundations. Soil heat stabilizer contains a sealed vertical shell with heat carrier, in which there are upper and lower parts of heat-exchange zone. Upon that at least one heat-exchange zone has annular insert which has extra specific surface area. Outer surface of the insert contacts with the inner surface of the shell in the heat-exchange zone. Cross-section area of the annular insert does not exceed 20 % of cross-section area of the shell cavity.

EFFECT: increasing of heat-transfer characteristics while keeping safe compactness of heat stabilizer, as well as increasing efficiency of soil heat stabilizer.
