AI Technical Summary
Existing technologies, when studying horizontal heat pipes, have failed to effectively address the changes in internal gas-liquid flow after the adiabatic section bends, especially the uneven liquid wetting under the influence of gravity and the difficulty in measuring gas pressure drop. Furthermore, the stainless steel liquid wick is difficult to visualize.
A visualization experimental device was designed, comprising a condensation section, an adiabatic section, and an evaporation section made of transparent glass. A stainless steel wire mesh liquid suction core was used, combined with a differential pressure sensor and a high-speed camera, to visualize the gas-liquid countercurrent flow and measure the gas pressure drop. The segmented structure simplifies the experimental process.
Uniform wetting of the wire mesh liquid absorber and measurement of gas pressure drop were achieved under horizontal conditions, simplifying the experimental process and enabling visual measurement of liquid wetting rate and circumferential distribution under different bending conditions.
