Description of the invention: [Technical field to which the invention pertains] The present invention relates to a heat pipe, and more particularly to a heat pipe having a light weight and having a better sealing effect. [Prior Art] At present, heat pipes are widely used for heat dissipation of electronic components having a large amount of heat generation because of their relatively fast heat transfer rates. Conventional hot stern tubes usually use steel with high thermal conductivity as the housing. However, with the emergence of versatile and ultra-thin electronic products, the requirements for heat dissipation devices are becoming more and more serious. It has become a goal to improve the use of titanium having a high thermal conductivity and a light weight as a heat pipe. However, when the heat pipe is sealed, the inner wall of the pipe mouth needs to be flattened to be in close contact with each other to achieve the sealing effect, but since the hardness of the titanium is high, the heat pipe using the material as the casing is in progress. When the large deformation amount is flattened, it is easy to produce cracks, which causes the vacuum in the tube body and the leakage of the working fluid to affect the thermal conductivity of the heat pipe. SUMMARY OF THE INVENTION In view of the above, it is necessary to provide a heat pipe which is light in weight and has a good sealing effect. The heat pipe 'includes a sealed casing, the casing includes a body, and one end of the pipe body forms a mouth portion, and the pipe body is made of titanium. The sealing portion houses a support body, and the support body is made of copper, Aluminum, 3 201100739 Iron, recorded, crane, group, 锢, 铢 or sharp-type heat pipe, including - pipe body, the end of the pipe body is formed as a sealing end, the pipe body is formed into a single-layer metal structure and made of titanium A support body made of another metal is disposed in the sealing end, so that the sealing end is formed into a double-layer metal composite structure.管 The body of the heat pipe is made of lighter weight titanium, making the heat pipe as light as possible. At the same time, the support can be made of copper, aluminum, stainless steel, low carbon steel, iron, nickel, tungsten, tantalum, molybdenum, niobium or tantalum, which has a small hardness and good ductility, and is easy to be used to a large extent. The deformation processing is supported and supported inside the sealing portion, and the sealing portion can be prevented from being excessively deformed when the sealing portion is subjected to the sealing process, thereby causing cracks, thereby affecting the heat conduction performance of the heat pipe.

The invention will now be further described in conjunction with the embodiments with reference to the drawings. As shown in FIG. 1 and FIG. 2, the heat pipe ίο includes a sealed casing 11'. The casing 11 is packaged with an appropriate amount of working fluid (not shown), and a capillary structure 12 is disposed on the inner wall surface of the casing 11. . The housing 11 includes a tube body 110 and a support body 120 disposed inside the tube body 110. The tube body 110 is made of titanium of lighter weight. The tubular body 110 4 201100739 has a circular cross section. The tube body 110 includes a cylindrical body 111 and is formed on the body 11; [a reduced tube portion 112 at one end. The shrinking portion 112 includes a tapered portion 113 connected to the body ln, an extending portion 114 connected to the tapered portion 113, and a mouth portion 115 formed at an end of the extending portion 114. The tapered portion 115 has a hollow truncated cone shape, and its outer diameter gradually decreases from the end to which the body 11 is connected toward the direction in which the extending portion 114 is located. The extending portion 114 extends outward from the end of the tapered portion 113 having a smaller outer diameter, and its outer diameter does not change. The sealing portion 115 includes upper and lower tube walls which are outwardly adjacent to each other by the distal end of the extending portion 114. The support body 120 is a tube body whose outer shape matches the inner surface of the reduced tube portion ^2. The support body 120 includes a positioning portion 122 corresponding to the tapered portion 113 of the reduced tube portion 112, a connecting portion 124 corresponding to the extending portion 117, and a sealing portion 126 corresponding to the sealing portion 115. The support body 120 is housed in the shrinkable tube portion 112 of the tube body 11A. The positioning portion 122 has a tapered tubular shape, and an outer surface thereof is in close contact with an inner wall surface of the tapered portion 113 of the constricted portion 112, and a position where the tapered portion 113 and the body ill are engaged extends to the tapered portion ι3 and The position at which the extension 114 is engaged. The positioning portion 122 is provided to prevent the heat pipe 1G from sliding in the axial direction of the pipe body 11 when the heat pipe 1G is not sealed and the support member 120 accommodated in the pipe portion 112 is prevented. The connecting portion 124 is connected to the end of the positioning portion 122, and the outer surface of the outer surface 5 201100739 is in close contact with the inner wall surface of the extending portion 114. The connecting portion 124 extends from a distal end of the positioning portion 122 having a smaller outer diameter to a position at which the extending portion 114 of the tubular body 110 is engaged with the sealing portion 115. The sealing portion 126 is formed in a flattened shape, and its outer surface is in close contact with the upper and lower tube walls of the sealing portion 115. The sealing portion m & includes an upper and a tube wall extending outward from the distal end of the connecting portion 124 and adjacent to each other. The support body 120 is made of a material having low hardness and good ductility, such as copper, shovel, stainless steel, low carbon steel, iron, ruthenium, crane, group, turn, 铢 or 铌, when the heat pipe 10 is sealed. That is, the end of the extension portion 114 of the heat pipe 1 及 and the end of the connection portion 124 provided therein are subjected to a flat sealing operation to form the sealing portion 115 of the tube body 11 及 and the inside of the tube portion 11 夹When the sealing portion of the support 12 is supported, the sealing portion 126 is supported by the sealing jaw 115 π to prevent the sealing portion 115 made of titanium from being deformed to cause cracks, and at the same time, due to the hardness of the material of the supporting body 120 It is small and has good ductility, and it is convenient to carry out the inflammatory and flat sealing π operation with large deformation amount, thereby achieving the sealing of the heat pipe. In the present case, the tube body 11 is formed as a single layer of metal, and is made of titanium. The sealing end of the tube body 11 is provided with a support body 120' made of another metal to form the sealing end into a double Layer metal composite structure. Due to the poor processing properties of titanium, the entire housing of the fish-preferred technology is compared with the heat pipe made of titanium, which can prevent cracks from occurring when the titanium pipe body is directly subjected to a large degree of flat sealing processing. The degree of vacuum in the housing and the leakage of the working fluid 6 201100739 leakage, affecting the thermal conductivity of the heat pipe. In summary, the present invention complies with the patent application of the invention patent. However, the above description is only for the purpose of the present invention.
