The specific embodiment
In order to make your juror can further understand feature of the present utility model and technology contents, see also following about detailed description of the present utility model and accompanying drawing, yet accompanying drawing only provide with reference to and be used for the explanation, be not to be used for the utility model is limited.
See also 1 figure and 2 figure, be respectively the local enlarged detail of cross-sectional schematic of the present utility model and 1 figure.The utility model provides a kind of Heat Pipe Capillary Organization Structure, the sealing pipe fitting that this heat pipe 1 is vacuum and has suitable length in being, and be sealed with an amount of working fluid (not shown); It roughly comprises hollow tube 10 and is located at capillary structure 11 on these body 10 internal faces.
This body 10 can be the made hollow tube of copper material, look these heat pipe 10 actual demand length and draw materials, after it seals the bottom earlier usually, insert capillary structure and working fluid again and via production processes such as degasification through heat treatment, beginning is further sealed its top, to finish this heat pipe 1.Yet the production process of heat pipe all belongs to known technology and does not belong to application category of the present utility model, so repeat no more.
This capillary structure 11 is attached on the internal face of above-mentioned body 10 and forms circle-shapedly, and all attaches on full pipe shaft 102 internal faces 103 of this body 10.When heat pipe 1 bottom is heated, because of after the working fluid of heat pipe 1 inside is heated, can become gas phase by liquid phase, so heat can be conducted to the top by heat pipe 1 bottom, make the working fluid answer of gas phase be liquid phase via cooling back, top again, produce capillarity by capillary structure 11 simultaneously,, so can circulate and carry out heat exchange so that working fluid is back to heat pipe 1 bottom.And the utility model mainly is: this body 10 has heating section 100 at least on its pipe shaft 102, in 1 figure, described heating section 100 is positioned at this place, heat pipe bottom, simultaneously, capillary structure 11 in the body 10 is two kinds of variety classeses, the capillary materials of pattern constitutes, and the capillary structure that is attached on the internal face 103 of this heating section 100 is first kind of capillary structure 110, described first kind of capillary structure 110 formed by powder sintered, set capillary structure then is second kind of capillary structure 111 on the internal face 103 of body 10 all the other pipe shafts 102 in addition, described second kind of capillary structure 111 can be for being woven the mesh grid (shown in 1 figure) that forms by metal wire, after curling and be attached on body 10 internal faces 103; Or to take out the channel form capillary structure (shown in 5 figure) on the internal face 103 that the tube side formula is formed at body 10.As described in Figure, second kind of capillary structure 111 is positioned at all the other positions of the condensation segment 101 and the pipe shaft 102 on heat pipe 1 top.
As shown in Figure 2, cause the discontinuous of capillary transfer for avoiding first kind of capillary structure 110 not to be connected with second kind of capillary structure 111, on making, the junction of above-mentioned two kinds of capillary materials is overlapped or closed butt joint, be able to continuous and unlikely interruption to guarantee the capillary transfer path.
Therefore, by above-mentioned contexture, can obtain the utility model Heat Pipe Capillary Organization Structure.
Shown in 3 figure, be applied to the user mode schematic diagram of L shaped pipe for the utility model heat pipe 1.Wherein, described heating section 100 is formed on an end place of heat pipe 1, the other end of this heat pipe 1 then is described condensation segment 101, and heating section 100 is contacted with thermal source 2, then be serially connected with a plurality of radiating fins 3 on the condensation segment 101, and second kind of capillary structure 111 that this heat pipe 1 is bent in the position can be mesh grid or groove, so this heat pipe 1 can be bent under the situation of not destroying capillary structure.
As shown in Figure 4, be the utility model heat pipe 1 ' be applied to user mode schematic diagram of U-shaped pipe.Wherein, because general U-shaped heat pipe 1 ' heating section 100 ' the be positioned at section place, the end that is the U font, so in the present embodiment, described heating section 100 ' be formed on body 10 ' the middle section, this body 10 ' two ends then respectively be described condensation segment 101 ', and heating section 100 ' equally and thermal source 2 ' contact, the a plurality of radiating fins 3 of two condensation segments 101 ' then be serially connected with jointly ', so can by first kind of capillary structure 110 ' powder sintered, and second kind of capillary structure 111 ' mesh grid or groove constitute this heat pipe 1 ' capillary structure 11 ', and reach heat pipe 1 ' the temperature of heating section 100 ' can bear higher, and all the other pipeline sections can also be suitable for the purpose of bend pipe.
In sum, the utility model with said structure passes through the capillary materials of two kinds of variety classeses, pattern as the capillary structure in this heat pipe, so that this heat pipe except the thermal source that can bear higher temperatures, can also be applicable on the bend pipe occasion.
Yet, the above only is a preferable possible embodiments of the present utility model, be not so promptly limit to scope of the present utility model, the equivalent structure that all utilization the utility model specifications and accompanying drawing content are carried out changes, and all in like manner all is included in the scope of the present utility model.
