Modulated porous wick evaporator for loop heat pipes: Experiment

The MBE multiscale behavior majorly accounts for the performance improvement: small pores (∼μm scale) creating great capillary force for liquid suction, large pores (∼10 μm scale) between clusters increasing surface area for liquid film evaporation, and vapor channels (∼mm scale) for vapor venting. Besides, small contact thermal resistance and reduced heat flow path in the evaporator also improve the LHP performance.
