Abstract
A heat pipe comprises a sealed shell, wherein the shell comprises a pipe body. One end of the pipe body is provided with a sealing part. The pipe body is made of titanium. A supporter is contained in the sealing part. The supporter is made of copper, aluminum, stainless steel, low-carbon steel, iron, nickel, tungsten, tantalum, molybdenum, rhenium or niobium. The whole weight of the heat pipe is light and the fissure caused by over large deformation when processing the sealing part is prevented, so as to protect the thermal conductivity of the heat pipe.
Description
Technical field
The present invention relates to a kind of heat pipe, particularly relate to a kind of light weight and have the heat pipe of better sealing effect.
Background technology
At present, because heat pipe has heat transfer rate faster, and be widely used in the heat radiation of the electronic component of the big caloric value of tool.Existing heat pipe adopts usually has the copper of high thermal conductivity as housing, but appearance along with multi-functional and ultrathin electronic product, the performance of heat abstractor and light-weighted requirement are also improved all the more, adopt titanium to become the target that people pursue as the housing of heat pipe with high thermal conductivity and lighter weight.Yet, heat pipe is when sealing, the inwall at mouth of pipe place need be flattened to mutually tight state of contact, to reach the effect of sealing, but because the hardness of titanium is higher, use this kind material to add in the flattening of carrying out the moderate finite deformation amount and be easy to generate crackle man-hour, thereby cause the vacuum in the body and the leakage of working fluid, influence the heat conductivility of heat pipe as the heat pipe of housing.
Summary of the invention
In view of this, the heat pipe that is necessary to provide a kind of lighter weight and has better involution effect.
A kind of heat pipe comprises a housing that seals, and this housing comprises a body, one end of this body forms a mouth-sealed portion, this body is made of titanium, and accommodates a supporter in this mouth-sealed portion, and this supporter is made by copper, aluminium, stainless steel, mild steel, iron, nickel, tungsten, tantalum, molybdenum, rhenium or niobium.
A kind of heat pipe comprises a body, and an end of this body forms sealing end, and this body forms the single-layer metal structure and is made of titanium, and is provided with one in this sealing end by another metal supporter, makes sealing end form the double-level-metal composite construction.
The body of described heat pipe is made by the titanium of lighter weight, makes the heat pipe overall weight lighter.Simultaneously, this supporter can be less by material hardness, and ductility material copper, aluminium, stainless steel, mild steel, iron, nickel, tungsten, tantalum, molybdenum, rhenium or niobium is preferably made, be easy to deformation processing largely, and be supported on the inside of this mouth-sealed portion, to add man-hour its deflection excessive and crack sealing can to prevent this mouth-sealed portion, thereby influence the heat conductivility of heat pipe.
Description of drawings
Fig. 1 is the stereogram of heat pipe one embodiment of the present invention.
Fig. 2 is the schematic diagram of the longitudinal cross-section of heat pipe shown in Figure 1.
The specific embodiment
The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.
As shown in Figures 1 and 2, this heat pipe 10 comprises an airtight housing 11, is packaged with an amount of working fluid (figure does not show) in this housing 11, and is provided with capillary structure 12 in housing 11 internal faces.
This housing 11 comprises a body 110 and is located at a supporter 120 of these body 110 1 end inside.
This body 110 is for to be made by the titanium of lighter weight.The cross section of this body 110 is circular.This body 110 comprises a columned body 111 and is formed at a draw portion 112 of these body 111 1 ends.This draw portion 112 comprises a convergent portion 113, extension 114 that is connected with this convergent portion 113 that is connected with this body 111 and a mouth-sealed portion 115 that is formed at these extension 114 ends.This convergent portion 115 is the round table-like of hollow, and its external diameter is reduced gradually by the direction of an end to these extension 114 places that connects this body 110.This extension 114 is stretched out by this convergent portion less end of 113 external diameters, and its external diameter is constant.This mouth-sealed portion 115 comprises that the end by this extension 114 outwards is close upper and lower tube wall mutually.
This supporter 120 is a body, and the inner surface of its profile and this draw portion 112 is complementary.This supporter 120 comprise a location division 122 corresponding with the convergent portion 113 of this draw portion 112, with corresponding a junction 124 of this extension 117 and a sealing 126 corresponding with this mouth-sealed portion 115.
This supporter 120 is contained in the draw portion 112 of this body 110.These location division 122 tapered tubuloses, its outer surface closely contacts with the internal face of the convergent portion 113 of this draw portion 112, and extends to the position that this convergent portion 113 is connected with extension 114 by the position that this convergent portion 113 is connected with body 111.The setting of this location division 122 can prevent that heat pipe 10 from adding man-hour sealing, and is housed in supporter 120 the endwisely slipping along body 110 in this draw portion 112.This connecting portion 124 is connected with the end of this location division 122, and its outer surface closely contacts with the internal face of this extension 114.This connecting portion 124 extends to the position that the extension 114 of this body 110 is connected with this mouth-sealed portion 115 by this location division less end of 122 external diameters.Sealing portion 126 is one and flattens shape, and its outer surface closely contacts with the upper and lower tube wall of this mouth-sealed portion 115.Sealing portion 126 comprises that the end by this connecting portion 124 stretches out and the close mutually upper and lower tube wall to applying.
This supporter 120 is lower by hardness, and the material that ductility is good, as copper, aluminium, stainless steel, mild steel, iron, nickel, tungsten, tantalum, molybdenum, rhenium or niobium are made, when this heat pipe 10 seals, promptly the terminal of the extension 114 of this heat pipe 10 and the end of being located at the connecting portion 124 in it are pressed from both sides flat involution operation, during with the mouth-sealed portion 115 that forms this body 110 and the sealing 126 that is located in this supporter 120 in it, sealing portion 126 is supported in this mouth-sealed portion 115, prevent that these mouth-sealed portion that is made of titanium 115 deflections from cracking greatly, simultaneously, because the material hardness of this supporter 120 is less, and ductility is better, conveniently carry out the flat sealing operation of the bigger folder of deflection, thereby realize the sealing of heat pipe 10.In this case, this body 110 forms the single-layer metal structure and is made of titanium, and is provided with one in the sealing end of this body 110 by another metal supporter 120, makes sealing end form the double-level-metal composite construction.Because the processing characteristics of titanium is not good, compare by the integrally manufactured heat pipe of titanium with the whole housing of prior art, can prevent directly to the titanium body press from both sides largely flat seal to add crack man-hour, thereby cause the interior vacuum of housing and the leakage of working fluid, influence the heat conductivility of heat pipe.
