DEVICE FOR HEAT STABILIZATION OF PERENNIAL PERMAFROST SOILS

摘要

The invention relates to thermal engineering in the field of construction, and specifically to individual seasonally-operating soil cooling devices/heat stabilizers. The solution is directed at broadening the temperature range for installing heat stabilizers, and at preventing remnants of leakproofing materials from entering a cavity of a sleeve which is filled with a coolant. The device contains a heat stabilizer based on a two-phase thermosyphon, including an above-ground capacitor portion and underground conveyance and evaporation portions, which are positioned in a sleeve with a coolant, which is in the form of a hollow cylindrical housing having a base and a sealing element on the upper end thereof with an aperture for installing a heat stabilizer. The sealing element is in the form of a separable compression seal fitting consisting of a support ring installed on a circular step provided in the sleeve, and of a pressure ring and sealing rings made of thermally expanded graphite, which are compressed between same.
