The hollow tube that one end closure is provided is as heat pipe package; The sticking plaster of one diameter less than above-mentioned hollow tube internal diameter inserted in the hollow tube, make and form a space between sticking plaster and the hollow tube inwall; Said mixture is injected above-mentioned space; Burn in reducing atmosphere, removing sticking plaster and organic solvent, and make the copper-containing compound fiber reduction become the copper fleece, this copper fleece is attached at the hollow tube inwall; Hollow tube is evacuated; In hollow tube, pour into an amount of working fluid; Hollow tube is sealed, working fluid is sealed in the hollow tube.And for example M259150 heat tube capillary structure patent in Taiwan is provided with heat conducting capillary structure in a heat pipe, and this capillary structure is that plural radial loop along this heat pipe forms around reaching axially extended fibrage; Wherein, it is thicker than extending the axial fiber of this heat pipe to be surrounded on this heat pipe fiber radially.The Taiwan M260343 tube wall heat pipe combined formula capillary structure patent of being heated and for example, include tube body of heat pipe and capillary structure, by plural groove and sintered powder are constituted, wherein plural groove is to extend axially and be formed on this body inner peripheral surface along this body, and sintered powder then is coated in the local place of at least one side of this body inner peripheral surface.No. 200513625 multilayer net fluid channel capillary structure in Taiwan and adopt traditional type heat pipe, flat plate heat tube and the loop hot-pipe patent of its making and for example, its capillary structure adopts wire netting to be made into sandwich construction, and the wire netting that wherein comprises the wavy fold of one deck at least is to form the fluid channel layer.It in the traditional type heat pipe concentric circles multilayer net fluid channel capillary structure that is affixed on inner tubal wall.Add a wavy supporting network in the middle of the upper and lower multilayer net fluid channel capillary structure in flat plate heat tube, the multilayer web frame of suitably oppressing upper and lower with closely connected in upper and lower plate inwall.Above the multilayer net fluid channel capillary evaporator of loop hot-pipe, add a wavy supporting network, fix evaporimeter.More than the multilayer net capillary structure of three formula heat pipes have the advantage of wire netting and fluid channel, the separation that comprise that capillary force is big, the liquid flowing friction resistance is little, steam and withdrawing fluid has certain degree etc.The present invention also proposes the production process of above-mentioned three formula heat pipes.Therefore above-mentioned traditional type heat pipe can not cause the usefulness slump of disastrous proportions at crooked or capillary structure easy fracture not when flattening.Above-mentioned flat plate heat tube can become the heat abstractor of computer chip easily with combination of fans with radiating fin.As Taiwan I233977 heat pipe patent, include the shell of a hollow; One is close to the capillary wick of inner wall of tube shell; And be sealed in working fluid in the shell; Wherein the capillary wick surface has one deck hydrophilic material.And for example Taiwan M264484 heat pipe multilayer capillary texture forming structure patent comprises a hollow heat pipe body and the mesh grid capillary structure of being located at this tube body of heat pipe inwall place; Wherein, this capillary structure is the curling shape that is formed circumference by one deck mesh grid through at least this capillary structure of folding.Mainly be divided into the groove heat pipe by the existing as can be known heat pipe of the explanation of above-mentioned prior art, three kinds of plug net heat pipe and powder sintered heat pipes, the best results of wherein working as the three dimensions capillary structure that has with powder sintered heat pipe, yet because the preparation method of powder sintered heat pipe, rod is in copper pipe in the middle of needing to insert earlier, fill sintering behind the capillary structure materials such as anaerobic copper powder then, after finishing, again the centre rod is taken out sintering, just this preparation method is when filling the anaerobic copper powder, cause air pollution easily, and be filled with its difficulty, especially more difficult filling when pipe range, and the uneven situation of filling is arranged easily, and central authorities' rod also often has shortcomings such as the difficulty of taking-up for consumptive material increases cost;
