Abstract
Keywords: Heat pipe, efficiency enhancement, CFD
In this paper a numerical model is used for analysis of parameters, which affects heat pipe operation. The steady state incompressible flow are solved in Cartesian coordinates in both vapour region and wick structure, using professional CFD (Computational Fluid Dynamics) software. The objective of this paper was to study of the parameters variation (temperature, heat power, heat flux) on the operation of heat exchangers with heat pipes.
