Abstract: Heat pipe has wide variety of application for thermal management, typically here use of heat pipe for 45 watt electronic part to maintain heat section temperature below 60°C to 70°C. The use of double layer mesh affords better result on single layer mesh heat pipes. For experimental results and analytical study, here diverse combination of double layer wrapped screen mesh is used with heat input to evaporator section of 45 watt. Darcy’s law and Knudsen diffusion explain well the heat transfer and flow through porous media, through the help of this it observed to provide coarse mesh at outer side and fine pore mesh at inner side for the best performance of heat pipe. Discussion on Empirical analysis and CFD results with experimental results conclusion made the best combination of double layer wrapped screen mesh for heat pipe afford to solve complex problems of heat and mass transfer. |
Keywords and phrases: heat pipe, double layer mesh, porosity, permeability, thermal resistance, heat transfer limits. |
