Low-temperature heat pipes with separate vapor and liquid ducts
Abstract
The paper discusses the design of a long heat pipe with separate vapor and liquid ducts to provide a high-density heat flux for any orientation in a gravitational field. The heat pipe described is characterized by an absence of wick in the transfer section and a presence of finely porous filler in the evaporator and the condenser. It is shown that such heat pipes exhibit low hydraulic resistance and can operate at any orientation in a gravitational field. The dependence of the longitudinal heat flux on temperature is examined for a vertical water heat pipe with an evaporating section in the upper part.
