Aluminum thermo-syphon and heat pipes were explored theoretically and tested experimentally to verify efficacy of various inhibitor solutions in different thermo-syphon geometries tested under different test conditions. Simple corrosion tests were also carried out within a vacuumed chamber to determine relative amounts of hydrogen generated when an aluminum sample is in direct, static contact with a test fluid. The results demonstrate that while there is good evidence that inorganic inhibitors can significantly reduce the production of NCG in an aluminum-water heat pipe, the complex nature of two phase fluid circulation in such devices still presents serious challenges to the reliability and adoption of inhibitor fluids for critical thermal management needs.
