Abstract: Accurate thermal conduction-based model is the key to the heat pipe-based thermal management simulation research． Based on the existing thermal conduction-based models，two conduction-based model for partially flattened heat pipes，the segmented anisotropic model and the layered segmentation model，were put forward in the present study． The results show that the segmented anisotropy model has higher accuracy in the case of low heat pipe operating temperature ( 28 ～ 38 ℃ ) ． The maximum relative error of heat pipe surface temperature is 5. 90% ． The layered and segmented model has higher accuracy in the heat pipe operating temperature range of 28 ～ 50 ℃ ． The maximum relative error of heat pipe surface temperature is 6. 51% ． And the effect of the effective thermal conductivity of the wick on the accuracy of the thermal conduction-based model was also investigated．

Key words: partially flattened heat pipe, thermal conduction-based model, thermal conductivity of the wick
