PLANT FOR COOLING THE SOIL AND SET OF PRODUCTS FOR CONSTRUCTION OF SUCH PLANT Russian patent published in 2018 - IPC E02D3/115 F28D15/02 

FIELD: instrument making; cooling.

SUBSTANCE: inventions relate to the means for cooling the soil, operating on the principle of gravitational heat pipes and vapor-liquid thermosyphons, and are intended for use in the construction of structures in the permafrost zone. Technical result is achieved by the fact that the plant has an evaporation zone with several branch pipes and a condensation zone with several condensers connected through a transport zone. Features of the plant consist in the fact that the condensation zone is made in the form of a monoblock construction having a nozzle for bleeding air, and its connection with the evaporation zone through a single transport channel in the form of upper and lower pipelines connected through a shut-off valve, and the presence of the collector in the evaporation zone to which the branch pipes are connected. Both pipe connections are detachable. Piping and branch pipes are made of easily deformable material, and the used coolant has vapor heavier than air. Kit for the installation of the plant includes the first product – monoblock condenser, the second product – upper transport pipeline and the third product in the form of a series-connected valves, pipeline and manifold with branch pipes. In the process of manufacture, the third product is filled with coolant, its pipeline and branch pipes are bent into coils around the manifold. Design of the plant and its configuration provide a technical result, consisting in more convenient transportation and the possibility of time separation of work on placing the underground and aboveground parts at the site of future operation. Connection of these parts through a single specified channel and the possibility of bending of its lower part facilitates the placement of the plant in the presence of other objects under construction close to it. Plant, after the connection of its parts, does not require refilling of the coolant under unfavorable construction conditions and is activated by opening the valve and then bleeding air through the nozzle.

EFFECT: technical result is the simplification of the overall design of the plant, which makes it possible to reduce the number of surface pipelines connecting the evaporation zone to the condensation zone without reducing the efficiency of these zones.
