摘要	Loop heat pipes (LHPs), as high-efficiency heat dissipation components, are considered to be superior thermal conductors beyond any known materials. To apply LHPs to mobile electronics, a small, thin and compact system needs to be designed. However, with the trend of miniaturization, the heat transfer performance of LHPs degrades rapidly due to the significant increase of working fluid backflow resistance. This work aims to propose an effective solution to this problem. In this work, the surface wettability gradient (SWG) is introduced into the ultra-thin LHP, and the influence of SWG on mass and heat transfer performance is studied comprehensively by using a transient three-dimensional numerical model. It is observed that the SWG can significantly increase the vapor-liquid circulation efficiency and improve heat transfer performance. Numerical experiments have been performed to compare the two kinds of LHPs with and without SWG. At the heat load of 4-6 W, the start-up time for LHP with SWG is shortened by 11.5% and the thermal resistance is reduced by about 44.3%, compared with the LHP without SWG. This work provides a solution for the performance-degradation problem caused by miniaturization, as a numerical reference for experiments.
