Hybrid Wick Heat Pipes for Operation in Microgravity and on Planetary Surfaces

It is recognized that constant conductance heat pipes (CCHPs) offer the simplest two-phase capillary-driven heat transport solution. The CCHP needs a wick structure throughout to return liquid from the condenser to the evaporator. Grooved wicks are typically used in spacecraft CCHPs, and Variable Conductance Heat Pipes (VCHPs). These grooves have a very high permeability, allowing very long […]
