Experiment Study and Visualization of the Startup Characteristics of a Loop Heat Pipe Enhanced by the Pressure Head due to Evaporation

Zhileng xuebao, 2020
A new-type of loop heat pipe (LHP), which is enhanced by the pressure head due to evaporation, was proposed and studied. Its wick was separated from the heating surface and a steam chamber was formed in which the phase change of the working fluid occurs ...
