DESCRIPTION OF THE INVENTION: TECHNICAL FIELD The present invention relates to a technique for manufacturing a flexible heat pipe by a tubular co-extrusion molding method, particularly relating to a hollow tubular fiber woven mesh composed of a polymer or a composite material and having a capillary action , a composite layer tube by a co-extrusion molding method. [Prior Art] In order to solve the problem of overheating of various device components, a heat dissipating device, such as a high temperature generated by an electronic component, is generally added to the heat generating component, and the heat energy is dissipated by the heat dissipating device. The conventional heat sink is composed of a wind flat and a heat sink, so that the high temperature generated by the operation of the electronic component is conducted by the fan through the heat sink. Although the heat dissipating device can provide the function of dissipating heat, the hot air is blown back and forth inside the electronic device to reduce the overall efficiency, and the noise generated by the fan during operation cannot be solved. Therefore, the new improvement proposes a heat pipe heat dissipation structure in which a heat pipe is disposed on the heat generating component to conduct heat to the outer heat sink. The heat pipe is a highly efficient heat transfer technology developed by G. M. Gr〇ver of the United States in 1963. It belongs to a kind of heat transfer element. The common heat pipe is composed of the shell, the wick and the end cap. The manufacturing method is to draw the inside of the heat pipe into a negative pressure state, and then fill the appropriate liquid, and the pipe wall has a liquid absorbing heart. Made of capillary porous material. One end of the heat pipe is an evaporation end, and the other end is a condensation end. When the heat pipe is heated for a period of time, the liquid in the capillary tube evaporates rapidly, the vapor flows to the other end under a slight pressure difference, and the heat is released, and the liquid is recondensed into a liquid, and the liquid flows back to the evaporation section along the porous material by the capillary force. The cycle not only transfers heat quickly. At present, the heat pipes are mainly made of copper pipes, which are provided with sintered porous materials or metal woven meshes. However, the problems that often occur in existing use are: capillary material shedding, deformation of the capillary material after bending of the heat pipe, and surface of the pipe body. It is short of short circuit, short circuit, heat generation and special bending equipment to form. Therefore, the main object of the present invention is to provide a bendable insulated heat pipe structure, which can achieve the risk that the capillary material does not fall off, the heat pipe does not block after bending, and the circuit is short-circuited. 5 200836908 At the same time, the heat pipe can be freely designed to meet the internal design of the device. Good heat dissipation. SUMMARY OF THE INVENTION An object of the present invention is to overcome the deficiencies of the prior art and to provide a tubular co-extrusion molding method for manufacturing a bendable heat pipe. The object of the present invention is achieved by the following technical solutions. First, a manufacturing method in which a polymer or a composite material and a fiber web having a capillary action are co-extruded into a multilayered tubular body is a capillary structure in which an inner tube wall of a molded hose is integrally formed and joined. Secondly, the tube body is connected to the metal socket with high heat transfer at the ends of the appropriate length to form a high heat transfer with hair (the thin tube material does not fall off, the heat pipe is not blocked after bending, heat insulation, electrical insulation and can be bent in any direction). The heat pipe member is made of a polymer or a composite material and a tubular fiber woven mesh having a capillary action, and is co-extruded into a multi-layer pipe body, and the inner tube wall of the co-extruded molding hose has an integrally formed joint. Capillary structure; the flexible heat pipe connects the high heat transfer metal socket at both ends of the appropriate length to form a heat transfer heat pipe with heat insulation, electrical insulation and arbitrarily bending direction. Applying co-extrusion molding technology, using fiber woven mesh The coextruded mandrel output forms a tubular inner layer, and after the outer layer of plastic or composite material is melted through the high temperature feed zone, one or more streams are extruded from a ring-shaped void of a die of one or more co-extruded die. At the same time, the inner layer of the tubular fiber web is simultaneously bonded and formed, as shown in Fig. 1.

The tubular fiber woven mesh of the inner layer of the composite layer may be a woven fabric such as glass wool, metal wire, polymer fiber or organic and inorganic composite fiber, and the outer layer of the composite layer tube is composed of a layer or Multi-layer polymer plastic or composite material composition, the composition should be high temperature resistant, anti-aging and thermoelectric insulating material. 6 200836908 The heat pipe assembly method is to pump the inside of the composite layer into a negative pressure state and then fill it into appropriate evaporation. The liquid of the degree, the two ends of the flexible layer of the appropriate length can be bent, and the metal socket with high heat transfer characteristics is connected, as shown in Fig. 3.

In the direction of the endothermic end or the heat dissipating end, the protrusion of the metal socket may be composed of a multi-wrinkle flap, a tMi dog or a columnar structure, and may be used before and after. Therefore, the present invention provides a bendable insulated heat pipe structure capable of reaching The capillary material does not fall off, the heat pipe does not block after bending, and the risk of short circuit is reduced. At the same time, the heat pipe can be bent and matched with the design inside the device. It is also possible to use the metal socket 35 to connect the two composite layers, as shown in Fig. 6.
