Abstract
The invention relates to a flat heat pipe structure. The flat heat pipe structure comprises a structure body; the structure body comprises a first plate body, a second plate body, a first capillary structure and working fluid; the first plate body and the second plate body are overlapped with each other; the first capillary structure is arranged between the first plate body and the second plate body; at least one steam channel is formed by the first capillary structure, the first plate body and the second plate body. With the adoption of the flat heat pipe structure, a flat heat pipe is thin and the steam channel is remained, so that the overall steam liquid circulating efficiency cannot be reduced due to the thin shape.
Description
Technical field
The present invention relates to a kind of flat-plate heat pipe structure, particularly relate to a kind of flat board with very thin thickness
Heat pipe structure.
Background technology
Existing electronics running gear is frivolous for moving towards towards being, and modern electronic running gear is the lightest
Its operation efficiency thin promotes the most therewith, but the lifting and integral thickness with operation efficiency reduces in it
The space of portion's holding electronic element is the most limited, when operation efficiency improves, and relative electronics unit
The heat produced during part computing increases the most therewith, therefore needs heat dissipation element to be assisted each electronics unit
The heat radiation work of part, again because of this electronics running gear because under conditions of thinning, its inner space is
The narrowest it is difficult to arrange the heat dissipation elements such as fan, therefore is only capable of arranging copper foil or aluminum slice as increasing
Big area of dissipation uses, but the lifting for heat dissipation is still not enough.
Take slimming because of entirety when heat pipe or temperature-uniforming plate are made slimming by prior art, cause
Thin type heat pipe is because filling out powder sintering difficulty after slimming, it is difficult to realize the structure of extremely thin type, or fill out powder
When being pressed into flat structure after sintering, inside heat pipe sintered powder or other capillary structure (grids
Body or corpus fibrosum) it is squeezed and destroys and anergy.
It addition, the temperature-uniforming plate of prior art is more micro-slimming, the supporting construction order within omission is all
Temperature plate is bled after sealing, and internal chamber is easily deformed, therefore prior art slimming heat pipe and temperature-uniforming plate
Internal steam channel is easily diminished by compression or even without steam channel, the internal overall vapour of impact
The efficiency of liquid circulation, therefore how to improve the steam-condensate circulating knot of the temperature-uniforming plate after slimming and inside heat pipe
Structure is the target instantly must improved.

One body, has one first plate body and one second plate body and one first capillary structure and a job
Fluid, described first and second plate body is superimposed with each other, this first capillary structure be arranged at this first and second
Between plate body, and this first capillary structure define at least one steam with this jointly with first and second plate body
Passage.
Described first capillary structure be grid body or corpus fibrosum or sintered powder or wire knitted body or
Agglomerated powder opisthosoma any of which.
Have more one second capillary structure, this second capillary structure be multiple groove or mesh grid wherein
Arbitrary.
It is open into and longitudinally staggered between these grooves.
Described body has more an endothermic section and a radiating part, and described second capillary structure is arranged at this
Endothermic section.
This first capillary structure is arranged at this body center along the axially extending of this body, described steaming
Vapour passage is arranged at the both sides of this first capillary structure.
Described first capillary structure is arranged in pairs, and described steam channel is formed at two first capillary structures
Between.
Described first and second plate body thickness is 0.01～0.15mm.
Described body has more an endothermic section and a radiating part and a bending section, described endothermic section and should
Radiating part connects this bending section, is arranged at the first capillary structure of this endothermic section and this radiating part.
Flat-plate heat pipe after can making slimming by flat-plate heat pipe structure provided by the present invention still can be protected
There is steam channel smoothly, make the flat-plate heat pipe internal process fluid of slimming still can be smoothed out vapour
Liquid circulates.

Detailed description of the invention
The above-mentioned purpose of the present invention and structure thereof and characteristic functionally, by according to institute's accompanying drawings relatively
Good embodiment is explained.
Refer to Fig. 1,2, for the stereo decomposing of first embodiment of the flat-plate heat pipe structure of the present invention
And constitutional diagram sectional view, as it can be seen, flat-plate heat pipe structure of the present invention, including: a body 1；
Described body 1 has one first plate body 11 and one second plate body 12 and one first capillary structure
13 and a working fluid 2, described first and second plate body 11,12 is superimposed with each other, and this first capillary is tied
Structure 13 is arranged between this first and second plate body 11,12, and this first capillary structure 13 with should be with
First and second plate body 11,12 defines at least one steam channel 14 jointly.
Described first capillary structure 13 is grid body or corpus fibrosum or sintered powder or wire knitted body
Or agglomerated powder opisthosoma any of which, the present embodiment is using agglomerated powder opisthosoma as explanation embodiment, but also
Do not regard it as and be limited.Described first and second plate body thickness is 0.01～0.15mm.
Described first capillary structure 13 of the present embodiment is arranged in pairs, and described steam channel 14 is formed
Between two first capillary structures 13.
Refer to Fig. 3, for the assembled sectional view of the second embodiment of the flat-plate heat pipe structure of the present invention,
As it can be seen, the present embodiment part-structure technical characteristic is identical with aforementioned first embodiment, therefore at this
