Abstract
A molding method of the heat pipe for capillary structure with controllable sintering position wherein said heat pipe is fabricated by said pipe body, grid-sintered composite capillary structure, core rod, evaporation section sintered capillary structure and powder limiting grid. This allows fabrication of the evaporation section sintered capillary structure with the help of the powder limiting grid, such that the capillary structure could be molded more easily while controlling accurately the sintering position and range. Moreover, with embedding of said grid-sintered composite capillary structure, the steam flow channel of the heat pipe could be further expanded and adapted to the flexible processing of the pipe wall, thus facilitating the fabrication and improving the vaporization efficiency of the working fluid with better applicability and industrial benefits.
