Abstract
The paper presents the results of the visual investigations of the working fluid vapour and non-condensible gaseous impurities interaction in low temperature heat pipe (LTHP) condensation zone.
The effect of the transferred heat flow amount on the vapour and non-condensible gaseous impurity (NCG) separation is established.
The obtained dependance allows to determine the minimal amount of the transferred heat flow from which the vapour and NCG will be dinamic mixed and the temperature profile will be simmetry in the heat pipe condensation zone.
Water, ethanol, acetone, Freon-11 were used as the working fluid, while air, argon and helium as NCG.
