Краткое описание

Experimental and theoretical studies are realized in order to determine the thermal performance of a Flat Miniature Heat Pipe (FMHP). In the experimental part of this study, a FMHP prototype including a capillary structure composed of parallel grooves is manufactured and a filling apparatus is developed in order to charge such FMHP. The heat transfer improvement obtained by comparing the heat pipe thermal resistance to the heat conduction thermal resistance of a copper plate having the same dimensions as the tested FMHP is demonstrated for different heat input flux rates, heat sink temperatures, and orientations. In the theoretical part of this work, a detailed mathematical model of a FMHP with axial grooves is developed in which the fluid flow is considered along with the heat and mass transfer processes during evaporation and condensation. The model is based on the equations for the mass, momentum and energy conservation, which are written for the evaporator, adiabatic, and condenser zones. The model can predict the maximum heat transfer capacity of FMHP, the optimal fluid mass, and the flow parameters. The comparison between experimental and model results shows the good ability of the numerical model to predict the axial temperature distribution along the FMHP.
