Description of the Invention: [Technical Field of the Invention] The invention relates to a heat pipe having a three-dimensional volume capillary structure layer, and more particularly to a manufacturing method. [Prior Art] With the continuous advancement and wide application of large-scale integrated circuit technology, the development of the information industry has advanced rapidly, and high-frequency high-speed processors have been continuously introduced. Due to the high-frequency and high-speed operation, a large amount of heat is generated per unit time. If the heat is not removed in time, the processor itself will increase, and the safety of the line will be greatly affected. The problem that must be solved. At present, due to the faster heat transfer rate of heat pipes, the heat transfer of electronic components is widely observed. The heat pipe includes a sealed tubular casing having a constant vacuum, and there is no sintered capillary structure in the casing and a proper amount of working liquid is filled in the casing, and one end of the heat pipe is an evaporation end and the other is One end is the condensation end. When the evaporation end of the heat pipe is subjected to enthalpy, the work = body steaming ^ vaporization, the steam flows to the condensing end under a slight pressure difference to release heat, and then condenses into a liquid, and the liquid returns to the evaporation end by the capillary pressure difference of the capillary layer, thereby The volume is quickly transferred from the evaporation end of the heat pipe to the condensation end. However, the performance of the heat pipe is affected by the capillary pressure difference ί back " 'L resistance factor of a factor of the eve of the 'the two factors vary with the size of the capillary structure of the capillary structure, when the capillary pores are small, it has Larger capillary pressure difference can drive the condensed liquid into the capillary structure and return to the evaporation end. However, the reduction of capillary pores increases the friction and home force of the working fluid return, that is, the working fluid reflux resistance increases. As a result, the working fluid returns slowly, and the heat pipe is liable to dry at the evaporation end. When the capillary pores are large, the working fluid is subjected to a small reflux resistance, and the capillary pressure difference of the condensed liquid sucking into the capillary structure is reduced. Small, reducing the flow rate of the working fluid, it will also cause the dry heat of the heat pipe at the evaporation end. Therefore, in order to meet the higher capillary force and low reflux resistance, the capillary structure with three-dimensional volume is provided in the heat pipe. However, the existing sintering method is not easy to control the pore distribution of the capillary structure layer of the heat pipe, which affects the performance of the heat pipe. SUMMARY OF THE INVENTION The technical problem to be solved by the present invention is to solve the problem that the heat pipe pore distribution is difficult to control, and provide a heat pipe manufacturing method which is easy to control the pore distribution of the heat pipe capillary structure layer. In order to solve the technical problem of the present invention, the heat pipe manufacturing method of the present invention comprises the steps of: preparing a raw embryo, forming a plurality of flaky green embryos having different particle sizes by doctor blade forming; and combining the windings to form the plurality of flaky raw materials having different particle sizes. The embryos are assembled into a multi-layered multi-stage integrated structure and rolled up to form a cylindrical embryo; the cylindrical embryo is placed in a tube of a heat pipe; sintered, and the tube that has been placed into the tubular embryo is sintered; Fill the tube with working fluid, vacuum and seal. The invention realizes the multi-layer multi-stage capillary structure layer with different pore sizes after sintering by forming the raw embryos with different particle sizes, and is easy to control the pore distribution of the capillary structure layer of the heat pipe and improve the performance of the heat pipe.

The third figure is a schematic diagram of the blade forming of the strip-shaped green embryo. The fourth picture is a schematic diagram of a sheet-like embryo. The fifth picture is a schematic diagram of the sheet body formed by the fixation of the sheet-like raw embryos. The sixth picture is a schematic diagram of the sheet-like raw embryos wound on the outer surface of the tie rod to form a cylindrical embryo.
