Prompt Description

Schematic diagram of the working principle of a three-phase closed thermosyphon, which is divided into three regions: evaporation section, adiabatic section, and condensation section. The core demonstrates the heat transfer and flow process of the three-phase medium of gas, liquid, and solid. Bottom Evaporation Section: The heat source inputs heat to the thermosyphon, so that the liquid working medium in the tube is heated to generate bubbles, and the solid particles in the tube also participate in enhancing heat transfer; the liquid working medium continues to evaporate to form steam, and the steam flows upward, and the generation and rise of bubbles also promote the movement of the fluid. Middle Adiabatic Section: There is no heat input or output in this area, which mainly acts as a channel. The steam continues to migrate upward, and the liquid phase begins a preliminary reflux trend along the tube wall. Top Condensation Section: The cold source takes away heat, and the steam condenses on the liquid film surface of the tube wall and becomes liquid again; the condensed liquid working medium flows back down the tube wall to the evaporation section under the action of gravity to complete the cycle.
