Abstract

See full text

The invention relates to thermal engineering construction, particularly to individual seasonal cooling devices, or temperature stabilizers of soils. The solution is aimed to expand temperature ranges at which temperature stabilizers can be installed and to prevent debris from sealing materials from entering into the well cavity having a coolant. The device contains a temperature stabilizer that functions as a two-phase thermal siphon and includes an aboveground condensing part and underground transporting and vaporizing parts. The temperature stabilizer is placed into the well along with coolant. The well is a hollow cylindrical body with a bottom and a capping element at a top end. The capping element includes a hole for receiving of the temperature stabilizer. The capping element is a detachable stuffing-box seal that includes a support ring installed on a round step in the well, a pressure ring, and thermally expanded graphite rings pressed therebetween.
