Research progress on enhanced thermal performance of flat plate heat pipe

As a highly efficient and compact gas-liquid two-phase heat transfer device, the flat heat pipe has been widely used in heat dissipation occasions with high heat flux in a narrow space. In order to promote the thermal performance of flat plate heat pipe, many scholars focused on how to enhance evaporation/boiling process, condensation process, vapor transport process and liquid transport process that operating inside the flat plate heat pipe. Besides, thermophysical property of working fluid and thermal conductivity of wall material had great impact on the thermal performance of flat plate heat pipe, hence they also had attracted the attention from scholars. In this paper, the researches on the enhancement of four operating process in the flat plate heat pipe, as well as the working fluid and wall material of the flat plate heat pipe in the recent decades were summarized. Based on the exited problems, this paper provides research scopes and references for future study on enhanced thermal performance of flat plate heat pipe.
