WebDec 1, 2024 · During 11 years' operation of thermosyphon subgrade, the permafrost table at sunny side elevates about 0.95 m, and basically reaches to the level of natural foundation. WebOct 22, 2024 · A thermosyphon is a type of natural circulation loop. It relies on the proper arrangement of the heating zone and cooling zone to cause a change in the density of the fluid within the loop, and the resulting thermal buoyancy drives the working fluid to transfer thermal energy.
