This paper describes an experiment and the analysis of the heat transport capability of a flat shaped heat pipe with a thickness of a few millimeter. Two types of heat pipes are investigated. One is a triangular channel heat pipe made of a column of triangular tubes with small leg height. The other one is a flat plate heat pipe with rectangular vapor space and axial grooves along the inside wall. The liquid recession in the liquid channel and the liquid pressure drop at the condenser end due to the capillary pressure of the liquid slug (slugging effect) were taken into consideration in the prediction of the heat transport capability. The prediction agreed well with the experimental data. The flat plate heat pipe with axial rectangular grooves had larger heat transport capability than the triangular channel heat pipe for the small slugging effect and the larger cross sectional area for the liquid return.
