Description of the invention: [Technical field of the invention] A thin heat pipe structure and a manufacturing method thereof, in particular, can realize thinning and improve heat transfer rate, and improve process yield _ type heat pipe structure and manufacturing method thereof. [Prior Art] The heat g is apparently excellent in thermal conductivity of several times to several tens of times of metals such as steel and aluminum. Therefore, it is used as a cooling element for various heat-related equipment. From the shape point of view, the heat pipe can be divided into a heat pipe in the shape of a circular tube, a flat shape, ... in order to cool the cooled parts of the electronic machine such as the CPU, based on the easy installation in the cooled and sturdy bottle __ age, should be fine A flat heat pipe is used for heat dissipation. With the miniaturization and space saving of the cooling mechanism, in the case of a cooling mechanism using a heat pipe, it is more necessary to strictly reduce the thickness of the pipe. A working fluid is provided in the heat pipe as a working fluid, and the working fluid accommodated in the space is subjected to a phase change and movement of evaporation, condensation, etc., and the hot portion is carried out. Action, the miscellaneous tube has a sealed cavity transfer. & Valley in the work of the domain (4) phase change and miscellaneous to heat the film, using the heart-warming heat pipe as a component of heat transfer 'put the heat pipe through the heat sink fin filling the low Buddha point work body in the hair _ At the filament (steaming - moving to the fins, at the fins (A condensing end takes the heat away, handing it to the scatter sheet) - the cooling fan will generate heat dissipation of the pair of electronic components of the 疋7°. 201248107 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 hollow pipe by sintering the metal powder, and then vacuum-filling the pipe body. The working fluid is finally sealed, and the heat pipe is required to be thinned due to the thinning requirements of the electronic device. The prior art is formed by flattening a hollow tube into a flat plate shape to meet the demand for thinning. Thereafter, the capillary sintered body is placed in the hollow tube body, and then the working fluid is filled and the pumping operation is performed. Although the heat pipe can be flattened, the right heat pipe is bent and shaped. Partial capillary sintering will decompose or depart from the original design The other part becomes a defective product. In addition, when the manufacturer makes the heat pipe into a thin type, the heat pipe is first filled with powder and then sintered (4) silky, and the Wei Na people turn the fluid and finally seal the pipe. After the tube surface of the _ is filled, the powder is filled and sintered, but the inner chamber of the tube is extremely narrow, which makes the filling operation difficult, and the capillary structure due to heat (4) has both continuous and capillary force transmission. In a space that is too narrow, the effect is limited. The narrowness affects the vapor-liquid circulation, and the vapor passage inside the heat pipe will be excessive due to excessive process and structure. Therefore, the prior art has the following disadvantages: 1. Thinning Heat pipe processing is not easy; 2. It is easy to damage the capillary structure in the heat pipe; 3. The manufacturing cost is high. [Inventive content] The main purpose of the moon is to provide a thin heat pipe junction that realizes the thinning of the heat pipe 201248107. _ touch (10) (8) face (4) transmission shaft, comprising: end: the body has two 1 accommodating space and - the first closed end and - the second closed pipe body working weeping body.
