Abstract : Conventional heat pipe performance can be improved by reducing the dependency upon the capillary pumping limitation. Electrodes mounted either in the working fluid vapor or its condensate produce an ion flow directed axially and in the same flow direction. The ion flow, through collision phenomena, picks-up the surrounding low velocity stream, increases its momentum and generates additional pumping pressure for the condensate. Performance can be improved even when low surface tension working fluids are used. (Author)
