Heat transfer characteristics of a variable conductance heat pipe, which uses a binary mixture of Freon R113 and R11 as a working fluid have been investigated. In a certain range of a heat input, the more volatile substance, R11, is gathered in the upper part of the cooling section, and condensation does not occur in this part. The length of this noncondensing region decreases with increasing the heat input, and a temperature difference between the heated and cooled wall is kept constant. The same characteristics are also observed in the case of the mixture of R113 and air. However, the mixture of R113 and R11 has a higher heat transfer rate and excellent performance for constant temperature operation. A theoretical model for the heat transfer in the cooling section of the heat pipe is proposed, and the calculated results well explain the experimental results.
