Mathematical model for heat transfer limitations of heat pipe

This article is about heat transport limitation standard-used construction wick heat pipes with various working fluids operating at temperatures from −30 °C to 140 °C. In this paper is the proposal and verification of a mathematical model for calculating heat transport limitations of heat pipe. The calculations of the various variants of the wick structure of heat pipe and working fluid are presented in diagrams as a dependency of the heat transport limitations on the working temperature. In the conclusion, the effect of these limits on the cooling power of the heat pipe is evaluated.
