Numerical investigation of a novel fin-plate thermosyphon (FPT), used to cool the high heat dissipation electronic devices, was performed. Three dimensional model of FPT is established using the Fluent software. The effects of fin pinch, fin thickness and fin type at the air side on thermal characteristics of FPT are presented with the air flow velocity various from 1.0 m/s to 4.0 m/s. The numerical results showed a good agreement with the corresponding experimental data. The heat transfer efficiency and pressure drops of FPT for plain fins were reduced by increasing the fin space. It also can be indicated that the cooling performance of FPT with serrated fins was better than plain fins for the same structural parameters.
► A novel diffusion welded fin-plate thermosyphon (FPT) was designed and performed. ► The plain fins heat transfer efficiency increases with the decrease of fin spaces. ► The fin thickness is less influential on FPT performance. ► Thermal performance of serrated fins is significantly much higher than that of plain fins.
