The liquid metal heat dissipation using heat from the chip as driving force is a high performance and smart thermal management method which has unique value in many application situations. In this study, numerical simulation was employed to investigate the self-driven heat transfer behavior based on thermosyphon effect of room temperature liquid metal. A comprehensive analysis on the effects like temperature of cold side, inclination and pipe diameter of the loop was performed, which may have important impacts on the system performance. This study provides strong data support for applications of this new technique.
