Abstract
A heat pipe comprises a sealed shell and a working medium. The heat pipe includes an evaporation section and a condensation section. The heat pipe further comprises a sealed inner container contained inside the shell. The inner container is made of soft metal material and size of the inner container can vary. The working medium is filled in the inner container. The inner container comprises a heat absorb part and a heat release part, wherein the heat absorb part and the heat release part are respectively flatly attached to and fixed on the inner wall of the shell. In the using condition, the heat absorb part of the inner container absorbs heat from the evaporation section to evaporate the working medium inside the inner container. The evaporated working medium of the inner container is abutted against the inner container and expand, enabling part of the outer wall of the inner container to abut against the inner wall of the shell and a plurality of rugged structures are formed on the inner wall of the inner container. The evaporated working medium liquefies when confronting cold and backflow to the evaporation section through the rugged structures. The inner container does not need to take up a large space inside the shell and adapts to a development demand of a light-type heat pipe.

The following specific embodiment further specifies the present invention in connection with above-mentioned accompanying drawing.
The specific embodiment
Fig. 1 is the longitudinal profile schematic diagram of the first embodiment of heat pipe of the present invention.Describe as an example of straight type tubular heat tube example in the present embodiment.This heat pipe 100 comprise a tubulose housing 10, be located at the inner bag 20 of the sealing in the housing 10 and be filled in working media 30 in this inner bag 20.One end of this heat pipe 100 is evaporator section 11, and the other end is condensation segment 15, its be connected between this evaporator section 11 and the condensation segment 15 for adiabatic section 13.
The cross section of this housing 10 can be circle, platypelloid type or other shapes, and it is formed by the good metal material manufacturing of the heat conductivilitys such as copper.These housing 10 interior formation one seal cavities 18, sealing space 18 is interior generally is pumped into vacuum or near vacuum.
Described inner bag 20 is contained in the housing 10, the stretched structure that it is formed by the soft metal manufacturing.This inner bag 20 is strip, and extends longitudinally to the other end by the end position near housing 10 along it.This inner bag 20 is in evaporator section 11 interior formation one endothermic section 21 of heat pipe 100, in condensation segment 15 interior formation one heat units 23 of heat pipe 100.Described endothermic section 21 and heat unit 23 flatly are attached on the inwall of housing 10 respectively, and are fixedly connected with it.These inner bag 20 interior formation one closed cavities 28 also generally are pumped into vacuum or near vacuum in this closed cavity 28, in order to the thermal evaporation that is subjected to of in the inner working media 30.Make in the situation of working media 30 evaporations in it in 11 heat absorptions of this evaporator section, the working media 30 after this inner bag 20 can be evaporated is supported and is expanded its outer wall is resisted against on the housing 10.Therefore, this closed cavity 28 also is the steam channel that becomes steam after being heated as working media 30.In the present embodiment, this inner bag 20 can be formed by Copper Foil or aluminium foil manufacturing.During implementation, the material of described inner bag 20 and thickness are not limited to the situation of present embodiment, and it also can be formed by the manufacturing of the stretchable soft metal material of other thickness.
Described working media 30 envelopes are located in this inner bag 20, and it is generally the higher liquid of latent heat such as water, alcohol, ammoniacal liquor and composition thereof.
Please consult simultaneously Fig. 2, during use, the evaporator section 11 of described heat pipe 100 is attached on the electronic component 50, and its condensation segment 15 is connected with a radiator 60.The endothermic section 21 of described inner bag 20 is arranged in the evaporator section 11 position corresponding with electronic component 50, and described heat unit 23 is arranged at the interior position corresponding with radiator 60 of condensation segment 15.After being absorbed by evaporator section 11, the heat of this electronic component 50 makes the working media 30 evaporation gasifications in the inner bag 20, working media 30 after this evaporation expands rapidly and supports inner bag 20, thereby make inner bag 20 elastic expansions, and then in the passage of the interior formation one gaseous working mediums circulation of the closed cavity 28 of inner bag 20.Working media 30 after this evaporation in closed cavity 28 interior to adiabatic section 13 and condensation segment 15 flow until behind the condensation segment 15 because heat outwards distributes by radiator 60, thereby make the working media 30 of gaseous state be liquefied as again liquid working media 30.Because the seal cavity 18 of this housing 10 is pumped into vacuum or near vacuum, inner bag 20 supported by gaseous working medium 30 and expand after its part outer wall be resisted against on the inwall of housing 10, the part outer wall is not resisted against on the inwall of housing 10, thereby the inwall that makes inner bag 20 forms rough structure, replace capillary structure in the conventional heat pipe with this, working media 30 after this liquefaction is back to evaporator section under the capillary force of the uneven structure of this inner bag 20, so circulation is constantly outwards distributed the heat of electronic component 50.Owing to be provided with the inner bag 20 that adopts the manufacturing of stretchable soft metal material to form in this heat pipe 100, have thinner thickness, need not to take space larger in the housing 10, be adapted to the growth requirement of thin type heat pipe.
Fig. 3 is the second embodiment of heat pipe of the present invention, the difference of present embodiment and last embodiment is: the evaporator section 11 of described housing 10a and condensation segment 15 adopt preferably metal material manufacturing of heat conductivility to form, and adiabatic section 13a adopts flexible material, form such as manufacturings such as rubber, plastics, thereby make evaporator section 11 and the arbitrarily angle setting of condensation segment 15 of this heat pipe 100, to satisfy the needs of different heat abstractors.
During implementation, the evaporator section 11 of described heat pipe 100 and the setting position of condensation segment 15 are not limited to the situation of present embodiment, and it also can be the heat pipe of U-shaped, L shaped or other shapes.
Be understandable that, for the person of ordinary skill of the art, can make change and the distortion that other various pictures are answered by technical conceive according to the present invention, and all these change the protection domain that all should belong to claim of the present invention with distortion.
