New Description: [New Technology Field] [0001] A heat pipe structure, especially a heat pipe structure that can reduce the thermal resistance pressure and greatly increase the vapor-liquid circulation inside the heat pipe to increase the heat transfer efficiency. [Prior Art] [0002] With the miniaturization and high performance of computers, smart electronic devices and other electrical devices, the heat transfer components and heat dissipating components used in the interior are also required to be compact. Designed for thinning and thinning, to meet the needs of users. The heat pipe is a heat-conducting element with excellent heat conduction efficiency, and its heat transfer efficiency is several times or even several tens of times higher than that of metals such as copper and aluminum, and thus it is used as a cooling element in various heat-related equipment. In terms of shape, the heat pipe is divided into a heat pipe having a circular tube shape, a heat pipe having a D-shaped cross section, a flat heat pipe, and the like, and the wife is used to cool the conduction of the heat source of the electronic device, and is convenient for mounting to the cooled component. In order to obtain a larger area of the contact surface, the flat heat pipe is widely used at the present stage, and the electronic device using the heat pipe as the heat conduction is also the same as the cooling mechanism is miniaturized and space is saved. A large number of flat heat pipes are selected for application. The conventional heat pipe structure has various manufacturing methods, for example, a metal powder is filled in a hollow pipe body, and the metal powder is sintered to form a capillary structure layer on the inner wall of the hollow pipe, and thereafter The tube body is vacuum-filled into the working fluid to finally seal the tube, or the mesh body of the metal material is built in the hollow tube body, and the mesh-shaped capillary structure is unfolded and naturally extended outwardly to the The inner wall of the hollow tube is formed with a capillary 10120125^No. A 〇 101 page 3 / 15 pages 1012003752-0 M429856 structural layer, after which the tube is vacuum-filled into the working fluid and finally sealed, but because of the foregoing Under the demand for miniaturization and thinning of electronic equipment, it is necessary to make the heat pipe into a flat type. Although the flat heat pipe can achieve the purpose of thinning, it extends another problem. Since the flat heat pipe sinters the metal powder on the inner wall surface of the heat pipe diameter body, the sintered body is completely and completely covered. On the inner wall, when the flat heat pipe is pressurized, the capillary structure (ie, the sintered metal powder or the network capillary structure) on the two sides of the flat heat pipe is susceptible to crushing damage, and the flat heat pipe is further The inner wall is detached or deformed, so that the heat transfer efficiency of the thin heat pipe is greatly reduced or it is dissipated; in addition, although the flat heat pipe can achieve heat source conduction, since the flat heat pipe is thinned, it is thinned. The capillary force of the internal capillary structure is insufficient, causing the working fluid to block the steam passage. Moreover, the area of the flow passage in the tube is reduced when the flat heat pipe is thinned, so that the capillary force is reduced, and the maximum heat transfer amount is also lowered. The overall thinning of the flat heat pipe leads to a reduction in the inner volume of the flat heat pipe, and the other reason is that the flat plate heat after being flattened is thinner. After causing obstruction blocking the central depression steam passage. Therefore, in order to solve the above-mentioned conventional disadvantages, a person in the field inserts a mandrel into the inner chamber of the flat heat pipe, and the mandrel forms a specific slit shape along the axial direction, and the inner wall of the cavity is formed by the slit The formed space is filled with metal powder and sintered to form a capillary structure, and finally the mandrel is pulled out, and then the central portion of the chamber where the capillary structure is located is subjected to press processing to form a flat shape, and the capillary structure and the chamber are The flat portion of the wall is in thermal contact, and a gap is provided on both sides of the capillary structure in the chamber as a steam passage to obtain a better vapor passage impedance, but due to the narrow capillary section, 10120125^"single number A〇101第4页/ Total 15 pages 1012003752-0 M429856 Therefore, the capillary force is reduced, resulting in extremely poor anti-gravity thermal efficiency and heat transfer efficiency. This shortcoming is the focus of current improvement. [New Content] [0003] In order to solve the above shortcomings of the prior art, the main purpose of the present invention is to provide a heat pipe structure capable of improving heat conduction and heat transfer efficiency.
