This paper describes experiments and analysis of the heat transport capability of axially grooved heat pipes. The heat pipes were made of aluminum axially grooved extruded pipes and the working fluid was R11. The effects of fluid inventory and inclination angle on the capillary pumping limit were investigated. A theoretical model has been developed to predict the temperature rise in the evaporator and the heat transport capability. In this model, the puddling effect, liquid recession into the groove bottom and the heat conduction in the evaporator were taken into consideration and the prediction agreed well with the experimental data. It was found that the temperature at the evaporator end bagan to increase just after all the grooves dried out at the evaporator end. The flooding limit and the evaporator and condenser film coefficients in the case of the gravity-supported operation were also investigated and compared with the performance of closed two-phase thermosyphons.
