Use of two-phase heat pipes with the enlarged heat-exchange surface for thermal stabilization of permafrost soils at the bases of structures

New two-phase heat pipes with the enlarged heat-exchange surface have been developed for thermal stabilization of permafrost soils at the bases of buildings and engineering structures. We have named them TIP – thermo-stabilizers with improved productivity (or with increased power). Their technical parameters and test results are given, and their operation in the North of Western Siberia and further applications are discussed.
