ABSTRAKT

An analytical solution for both the liquid and vapor flows inside a conventional heat pipe coupled to an analytical solution for the temperature inside the heat pipe wall is presented. The model is based on the definition of a periodic domain on which Fourier series expansion can be applied. This approach enables to develop a general model that can cope with both flat plate heat pipes and cylindrical heat pipes. Expressions of the 3D temperature field in the heat pipe wall and the 2D pressure and velocity fields in the liquid and in the vapor are given. The maximum heat transfer capability as well as the thermal resistance of a heat pipe, for any geometrical configuration with several heat sources and heat sinks can be directly extracted from the results. An example of model application for cylindrical heat pipes is presented in order to highlight the capabilities of such analytical solutions.
