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.

Detailed description of the invention
Fig. 1 is the longitudinal profile schematic diagram of the first embodiment of heat pipe of the present invention.Be described for straight type tubular heat tube in the present embodiment.The housing 10 that this heat pipe 100 comprises a tubulose, the working media 30 be located at the closed inner bag 20 of one in housing 10 and be filled 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 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 metal material manufacture that the heat conductivilitys such as copper are good.Form a seal cavity 18 in this housing 10, be generally pumped into vacuum in sealing space 18 or close to vacuum.
Described inner bag 20 is contained in housing 10, its by soft metal manufacture can drawing configuration.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 forms an endothermic section 21 in the evaporator section 11 of heat pipe 100, in the condensation segment 15 of heat pipe 100, form a heat unit 23.Described endothermic section 21 and heat unit 23 are flatly attached on the inwall of housing 10 respectively, and are fixedly connected with it.Form a closed cavity 28 in this inner bag 20, be also generally pumped into vacuum in this closed cavity 28 or close to vacuum, in order to working media 30 in the inner by thermal evaporation.When the heat absorption of this evaporator section 11 makes working media 30 in it evaporate, this inner bag 20 can be supported by the working media 30 after evaporating and expand its outer wall is resisted against on housing 10.Therefore, this closed cavity 28 is also the steam channel becoming 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 manufacture.During concrete enforcement, the material of described inner bag 20 and thickness are not limited to the situation of the present embodiment, and it also can be formed by the manufacture of other thickness stretchable soft metal material.
Described working media 30 envelope is located in this inner bag 20, and it is generally the higher liquid of the latent heat such as water, alcohol, ammoniacal liquor and composition thereof.
Please refer to Fig. 2, during use, the evaporator section 11 of described heat pipe 100 is attached on an 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 at position corresponding with electronic component 50 in evaporator section 11, and described heat unit 23 is arranged at position corresponding with radiator 60 in condensation segment 15.The working media 30 in inner bag 20 is made to evaporate gasification after the heat of this electronic component 50 is absorbed by evaporator section 11, working media 30 undergoes rapid expansion after this evaporation supports inner bag 20, thus make inner bag 20 elastic expansion, and then in the closed cavity 28 of inner bag 20, form the passage of a gaseous working medium circulation.Working media 30 after this evaporation flows until after condensation segment 15 to adiabatic section 13 and condensation segment 15 in closed cavity 28, because heat is outwards distributed by radiator 60, thus makes the working media 30 of gaseous state be liquefied as liquid working media 30 again.Seal cavity 18 due to this housing 10 is pumped into vacuum or close to vacuum, inner bag 20 supported by gaseous working medium 30 and expand after its outer wall be resisted against on the inwall of housing 10, outer wall is not resisted against on the inwall of housing 10, thus make the inwall of inner bag 20 form rough structure, the capillary structure in conventional heat pipe is replaced with this, the working media 30 of this post liquefaction is back to evaporator section under the capillary force of the uneven structure of this inner bag 20, and so the heat of electronic component 50 constantly outwards distributes by circulation.Owing to being provided with the inner bag 20 adopting the manufacture of stretchable soft metal material in this heat pipe 100, there is thinner thickness, without the need to taking space larger in housing 10, being 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 the present embodiment and previous embodiment is: the evaporator section 11 of described housing 10a and condensation segment 15 adopt the good metal material manufacture of heat conductivility to form, and adiabatic section 13a adopts flexible material, as rubber, plastics etc. manufactures form, thus the evaporator section 11 of this heat pipe 100 and condensation segment 15 can be arranged, with the needs of satisfied different heat abstractor by angle arbitrarily.
During concrete enforcement, the evaporator section 11 of described heat pipe 100 and the setting position of condensation segment 15 are not limited to the situation of the present embodiment, and it also can be the heat pipe of U-shaped, L shape or other shapes.
Be understandable that, for the person of ordinary skill of the art, the change and distortion that other various picture answers can be made by technical conceive according to the present invention, and all these change the protection domain that all should belong to the claims in the present invention with distortion.
