Description of the invention: [Technical field of the invention] A thin heat pipe structure and a manufacturing method thereof, in particular, a method of increasing the vapor-liquid diffusion efficiency by opening mutually interlaced channels on the inner wall of the heat pipe to make the heat pipe axial and diameter A thin heat pipe structure that conducts heat and a method for manufacturing and manufacturing the same. [Prior Art] The apparent heat conductivity of the heat pipe is approximately several times to several tens of times that of a metal such as copper or aluminum, and is excellent. Therefore, it is used as a cooling element for various heat-related equipment. In terms of shape, the heat pipe can be divided into a heat pipe in the shape of a circular pipe and a heat pipe in a planar shape. In order to cool a cooled component of an electronic device such as a CPU, a planar heat pipe is preferably used from the viewpoint of easy attachment to a member to be cooled and a wide contact area. With the miniaturization and space saving of the cooling surface, the thickness of the heat pipe is also required in the case of a cooling mechanism using a heat pipe. A space is provided inside the heat pipe as a flow path of the working fluid, and the working fluid accommodated in the space is thermally transferred by phase change and movement of the field, condensation, and the like. Next, the detailed Qing _ _, the sealed hollow part of the ’ 藉 藉 藉 藉 藉 的 的 的 卫 卫 卫 卫 卫 卫 卫 卫 卫 卫 卫 卫 卫 卫 卫 卫 卫 卫 卫 。 。 。 。 Therefore, the industry uses a heat pipe as a heat-conducting component, and the heat pipe is placed in the heat-dissipating film. The low-fog point working liquid filled in the heat S is used to move the heat-emitting electronic component (evaporation end) to the heat-dissipating fin to move toward the heat-dissipating fin. At the heat dissipation (condensing end), the heat generated by the heat-generating electronic components is transferred to the fine film, and the heat-dissipating fan will take away the heat of 201245651, and the heat dissipation of the electronic components. The heat pipe is manufactured by filling a hollow pipe body with a metal powder, and forming a capillary structure layer on the inner wall of the ten-tube by means of sintering, and then vacuum-filling the pipe body. The human working fluid is finally sealed, and the heat pipe needs to be made thin because of the thinning requirements of the device. The principle of the uniform temperature plate is the same as that of the heat pipe through the evaporation and condensation of the working fluid for heat conduction. The only difference is that the heat pipe mainly adopts axial heat conduction, and the temperature equalizing plate is the heat conduction of the large-area approximate surface and surface, just like the current The electronic equipment is designed to be thinner, so in order to use it with the electronic equipment, it is necessary to make the heat pipe or the temperature equalizing plate as a thin design. The conventional technology is to flatten a heat pipe into a flat plate shape, so as to meet the demand for thinning, the heat pipe is made into a thin type. The heat pipe is filled and sintered, and then the heat pipe is flattened, and then the heat pipe is flattened. After filling the working fluid, the tube is finally sealed, or the tube of the heat pipe is first pressed into a flat shape, and then the powder filling and sintering operation is performed. However, the inner chamber of the tube body is extremely narrow, which makes the filling operation difficult, and The capillary structure in the heat pipe must have both support and capillary force transmission, and the effect is limited in a space that is too narrow. In addition, the vapor channel inside the heat pipe will affect the vapor-liquid circulation due to excessive stenosis, and this process and structure are not suitable. Among them, the biggest problem in the prior art is that although the thinned heat pipe has a large heat and heat dissipation area, the heat pipe only has an axial heat conduction effect, and cannot be achieved for radial heat conduction; therefore, the prior art has the following disadvantages. : 1·Thin-shaped heat pipe processing is not easy; 201245651 2·It is easy to damage the capillary structure in the heat pipe; 3. The manufacturing cost is high; 4. The heat cannot be transmitted radially. SUMMARY OF THE INVENTION A primary object of the present invention is to provide a thin heat pipe structure having both heat conduction functions in both axial and radial directions. Another object of the present invention is to provide a thin heat-synthesis manufacturing method which can be made into a thinned heat pipe. In order to achieve the above object, the present invention proposes a thin heat pipe structure comprising: a pipe body, a mesh body; the pipe body has a chamber, and the inner wall of the chamber has The first channel and the second channel are interlaced with each other, and the mesh body has a plurality of meshes, and the mesh body is inside the chamber wall. In order to achieve the above object, the present invention provides a method for manufacturing an age structure comprising the steps of: preparing a hollow tube body and a mesh body; opening at least the first channel and at least the inner wall of the tube body; a second channel; a δ-shaped mesh body is attached to the inner wall of the tube body; the tube body is pressurized to form a flat shape; the tube body is evacuated and filled with a working fluid; and the tube body is closed. Through the method of the invention, the method for making the thin knot can transfer the heat and the heat of the butterfly, and greatly improve the heat transfer efficiency. The above object and structure of the present invention and the structure of the Wei will be based on the figure 201245651. The preferred embodiment of the formula is illustrated.

Please refer to FIGS. 7 and 8 for a schematic view of the application of the thin heat pipe structure of the present invention and a cross-sectional view taken along line AA. As shown in the figure, when the pipe body η has a heat receiving end Ua and a heat radiating end lib, the heated end 11a is In contact with the at least one heat source 3, and the heat dissipation end lib is in contact with the at least one heat dissipating component 4, in the embodiment, the heat dissipating component 4 is illustrated by a heat sink, but is not limited thereto, when the heat source 3 is generated. The heat is absorbed by the heated end 11a to cause the liquid working fluid 13a to be vaporized and converted into the vapor working fluid 13b, and the vapor working fluid 13b is transmitted to the heat radiating end lib through the gap between the mesh bodies 12 and The cooling end lib is cooled, and the cooled working fluid 13b is condensed into a liquid working fluid 13a' and diffused back through the first and second channels 111a, 111b on the inner wall 1111 of the chamber 111 of the tube 11.

When the heat absorbing side 11c absorbs the heat generated by the heat source 3, the liquid working fluid 13a is evaporated and converted into steam. The working fluid 13b is conducted to the heat dissipating side lid to be cooled, and the liquid working fluid 13a which is condensed by the cooling is returned to the endothermic side 11c along the first and second channels 1111a, 1111b to continue the vapor-liquid circulation.
