Abstract: A type of flat heat pipe with micro rectangle grooves was developed. The configuration and working principle of this type of heat pipe were discussed and the capillary limitation in the heat pipe was deduced theoretically. The effects of the parameters such as the heat flux, the working temperature, the working liquid and the inclining angle on the heat pipe were studied experimentally，and the heat transfer characteristics, the empirical correlations for the heat transfer coefficient of the evaporator and condenser surface were obtained to help the engineering design. The study indicates that the micro rectangle grooves flat heat pipe is characterized by high heat transfer capability with good prospects for cooling electronic components.

Key words: pyrology, heat transfer performance, flat heat pipe, micro rectangle grooves
