Two-phase closed thermosyphon device for power transmission infrastructure and method of construction thereof

Abstract

The application belongs to the technical field of power transmission and transformation, and provides a two-phase closed thermosyphon device for power transmission and transformation foundation and a construction method thereof. A separator is arranged between an evaporation section and a condensation section, and an outlet end of the separator is located at an outlet position of an adiabatic section. The evaporated working medium is accumulated at the top of the adiabatic section, the problem of dry inner wall at the connecting position of the condensation section and the adiabatic section is solved, and the flow resistance of the condensed working medium is reduced. In combination with the gas-liquid separator arranged in the adiabatic section, the shear stress between the gas phase and the liquid film is maximally reduced through the gas-liquid separation, the gas-liquid interaction is reduced, the working medium circulation effect is further ensured, the frozen soil rapid warming speed is improved, and the device is used for power transmission and transformation foundation.
