Detailed description of the invention
In order to describe technical characterstic place of the present utility model in detail, after hereby lifting preferred embodiments below and coordinating graphic explanation such as, wherein:
As shown in Figures 1 to 4, a kind of heat pipe 10 with fiber hair fine texture that this utility model the first preferred embodiment is provided, mainly made hydrodynamic by body 11, knitmesh capillary structure 13, fiber hair fine texture 15 and one and formed, wherein:
This body 11, in flat and closed at both ends, this body 11 is sequentially defined bringing-up section H, an adiabatic section A and a condensation segment C by one end to the other end, and defines this bringing-up section H and this condensation segment C and lay respectively at the two ends of this body 11.
This knitmesh capillary structure 13, is located at this body 11 inwall, and is located at least in bringing-up section H whole of this body 11.In the present first embodiment, this knitmesh capillary structure 13 is sintered in this body 11 inwall, and is positioned at bringing-up section H whole of this body 11.This knitmesh capillary structure 13 can provide the effect of the heating surface (area) (HS increasing this bringing-up section H, it is also possible to increases the reservoir storage of this bringing-up section H, further, it is also possible to increase the capillary force to liquid.
This fiber hair fine texture 15, gathered by several fibers and formed, this fiber hair fine texture 15 is in flat strip, and form two flat contact surfaces 16, in this fiber hair fine texture 15 is arranged at this body 11 and on centrally located axis, and the major axis along this body 11 extends, and is positioned at this bringing-up section H, this adiabatic section A and this condensation segment C；This two contact surface 16 of this fiber hair fine texture 15 amplexiforms in this body 11 inwall, and this space within body 11 is i.e. occupied a part by this fiber hair fine texture 15, and then is divided into two sub spaces 17.In the present embodiment, this fiber hair fine texture 15 is formed by several tinsel boundlings.
This makees hydrodynamic, fills in this body 11.Wherein, this is adsorbed on as hydrodynamic and is difficult to show on graphic in this knitmesh capillary structure 13 and this fiber hair fine texture 15, and owing to being the very known element of heat pipe industry institute as hydrodynamic, therefore holds and the most schematically represent it.
It is explained above the framework of this first embodiment, next the use state of this first embodiment is described.
As shown in Figure 4, bringing-up section H of this body 11 contacts a thermal source (not shown), and then receive heat energy produced by this thermal source, and then make to be positioned at this bringing-up section H this evaporate by heat into steam as hydrodynamic, then diffuse to this condensation segment C via this two subspace 17.Owing to this condensation segment C does not has other thermal source heat supplies, therefore this in vaporous is made hydrodynamic and is i.e. condensed into liquid because meeting cold, and penetrates into this fiber hair fine texture 15 and be back to this bringing-up section H, and is heated and forms vaporous.Circulation the most repeatedly, i.e. can reach the effect of quick conductive and samming.
Wherein, owing to this first embodiment uses fiber hair fine texture 15 and knitmesh capillary structure 13, even if therefore this body 11 is flattened and is bent, also do not allow to tend to have the situation collapsed to occur, because for burning fine texture, the capillary structure of copper powder sintering is easiest to when deformation produce the problem collapsing or damaging.Therefore, this case may insure that, in the case of body 11 is flattened and bent, capillary structure still will not be damaged, and then ensure that the reflowing result making hydrodynamic, and overall heat conduction or even temperature effect are maintained.
Owing to industry is all known, the highest then capillary force of voidage of capillary structure is more for declining, and the voidage of capillary structure in certain scope time, maximum heat biography amount (Qmax) can be just best, therefore, fiber hair fine texture 15 and knitmesh capillary structure 13 are used, when can effectively avoid body 11 to be flattened and bend, collapsing or become big situation in space, and then may insure that capillary force is to maintain maximum heat biography amount.
Referring again to Fig. 5, a kind of heat pipe 10 ' with fiber hair fine texture that this utility model the second preferred embodiment is provided, take off first embodiment before being the most generally same as, difference is:
This knitmesh capillary structure 13 ' is positioned at the whole of bringing-up section H of this body 11 ' and the local of this adiabatic section A.
For such structure is compared to first embodiment, owing to the length of this knitmesh capillary structure 13 ' is come longer compared with the knitmesh capillary structure 13 in first embodiment, therefore the liquid that what can condense what tube wall makees the return flow path that hydrodynamic provides longer, relative, but the volume of this two subspace 17 ' of part can be occupied due to the volume of this knitmesh capillary structure 13 ', the flow path making hydrodynamic making gaseous state becomes the narrowest and small, therefore, visual use demand decides whether to use the structure of this second embodiment.
Remaining structure of this second embodiment and the effect that can reach take off first embodiment before being generally same as, and appearance does not repeats.
Referring again to Fig. 6, a kind of heat pipe 10 with fiber hair fine texture that this utility model the 3rd preferred embodiment is provided ", take off the second embodiment before being the most generally same as, difference is:
This knitmesh capillary structure 13 " be positioned at this body 11 " whole and this adiabatic section A whole of bringing-up section H.
For such structure is compared to the second embodiment, due to this knitmesh capillary structure 13 " length come longer compared with the knitmesh capillary structure 13 ' in the second embodiment; therefore can make hydrodynamic for being condensed in the liquid of tube wall longer return flow path is provided; be relative; but can be further by this knitmesh capillary structure 13 " occupy this two subspaces 17 of more parts " volume; making the flow path making hydrodynamic of gaseous state become the narrowest and small; therefore, visual use demand decides whether the structure of employing this third embodiment.
Remaining structure of this third embodiment and the effect that can reach take off first embodiment before being generally same as, and hold and do not repeat.
Refer again to Fig. 7, a kind of heat pipe 40 with fiber hair fine texture that this utility model the 4th preferred embodiment is provided, take off first embodiment before being the most generally same as, difference is:
This fiber hair fine texture 45 only has this contact surface 46, and amplexiforms in this body 41 inwall, and this fiber hair fine texture 45 does not amplexiform with this body 41 relative to the position of this contact surface 46 and is separated by a preset distance.Consequently, it is possible to this space within body 41 is the most only occupied a part by this fiber hair fine texture, it is not divided into two sub spaces.
Remaining structure of this 4th embodiment and the effect that can reach take off first embodiment before being generally same as, and appearance does not repeats.
In addition, be worth supplementary notes be, this fiber hair fine texture 15 (45) in aforementioned four embodiments it is not absolutely required to be arranged on the central axial line of this body 11 (41), and the side being arranged at the axis in this body 11 (41) also can have the function that its capillary structure should possess.
