Abstract: A molding method for a thin-profile composite capillary structure includes the steps of preparing a metal grid and metal powder separately; attaching a liquid medium onto the metal grid by means of spraying or brushing or steeping; attaching uniformly the metal powder onto the grid with the liquid medium; and fixing the metal powder onto the surface of the grid by means of sintering, such that a sintered powder layer is formed onto the surface of the grid. The structure includes a metal grid, which is of planar grid pattern made of woven metal wires. A sintered powder layer is sintered onto a lateral surface of the metal grid from the metal powder. The thickness of the sintered powder layer is 0.1 mm-0.7 mm. The total thickness of the thin-profile composite capillary structure is 0.2 mm-0.8 mm, thus presenting flexibility. The thin-profile composite capillary structure is particularly suitable for a heat pipe.

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.

Abstract: A radiator fan module has a fan assembly, cooling fin and heat conductor. The fan assembly has a shell seat and fan blade, an air outlet is set at one side of the shell seat, the cooling fin is set correspondingly to the outlet, and the cooling end of the conductor is mated with the fin. The outlet forms an inward extended wall, an outward extended wall and an extended inner space set between the outlet and fan blade. The outlet has a width-reducing pattern. A notched space is formed externally between the inward extended wall and shell seat. An inward extended heat conductor is formed by the extension of the inner end of the cooling fin and is located within the range of the extended inner space, and provided with a blade corresponding side that is located correspondingly to a peripheral position of the blade.

Abstract: The heat pipe structure includes a pipe body, hollow groove and capillary tissue. The pipe body contains a heat-conducting end and a radiating end. The capillary tissue of a predefined thickness is adapted to an inner wall of the pipe body. The inner surface of capillary tissue is located correspondingly to the section of the heat-conducting end, where a portion with greater thickness is shaped from another section of the capillary tissue. The portion is of single side, a plurality of sides or annular structure. Thus, the heat conduction efficiency of the heat-conducting end greatly improves. The non heat-conducting sections of the capillary tissue remain still with respect to thickness, and the guide space expands to facilitate guiding of gaseous working fluid to the radiating end, thus achieving an optimum heat radiation effect.

Abstract: The panel-type heat sink module combines the heat-conducting panel, fin heat sink, diversion tank, fan and heat pipe into a single module. There is a heat-conducting surface and an assembly surface of the heat-conducting panel. The fin heat sink is assembled onto the assembly surface. The diversion tank is adapted onto the assembly surface and located nearby the fin heat sink. The diversion tank includes a fan container and a diversion channel. The fan is assembled into the fan container, and the heat pipe is assembled between the assembly surface and the fin heat sink. The heat pipe penetrates through the diversion tank; thus, the heat sources guided by the heat-conducting panel will be uniformly guided into the fin heat sink and diversion tank via the heat pipe. An air stream generated by the fan flows towards the fin heat sink, improving heat-radiation, and reducing assembly space.

Abstract: The sealing method and construction of the sealing end for a heat conductor includes a heat conductor for vacuum pumping and sealing placed within an enclosed operating space, wherein an open end is preset for the heat conductor. Next, vacuum pumping is performed for entire enclosed operating space, thereby finishing the vacuum pumping procedure of heat pipe. Then, the open end of heat pipe is welded by fusing within enclosed operating space, wherein the sealing end of heat conductor forms a welded close end. A compression procedure can be neglected, thereby saving more manufacturing cost and offering a higher structural strength for the sealing part.
