The specific embodiment
See also Fig. 1, the loop hot-pipe of the present invention's one better embodiment comprises an evaporimeter 10, connect this evaporimeter 10 opposite end pipeline 20 and be sheathed on some radiating fins 30 on the pipeline 20.This pipeline 20 connects the opposite end of evaporimeter 10, makes evaporimeter 10 and pipeline 20 form a sealed circuit.Be filled with hydraulic fluid (as shown in Figure 3) in this loop, this hydraulic fluid can be water, alcohol etc.Described pipeline 20 can be by making with the pliability material of hydraulic fluid compatibility, as copper, aluminium or stainless steel etc.One end of this evaporimeter 10 absorbs the heat of a heat-generating electronic elements such as CPU generation, and hydraulic fluid is evaporated, steam flows out along pipeline 20, through radiating fin 30 coolings, steam is cooled to liquid, liquid is by the other end of pipeline 20 inflow evaporators 10, and so, loop hot-pipe has been finished hydraulic fluid by the process of steam to cooling.These radiating fins 30 are near an end of evaporimeter 10 heat absorptions, with cooled vapor.In the present embodiment, radiating fin 30 sheathed part pipeline 20 be crushed.In other embodiments, radiating fin 30 sheathed part pipeline 20 can not be crushed.Be appreciated that ground, on the pipeline 20 other heat dissipation elements can be installed, be used for steam in the cooling line 20.
See also Fig. 2 and Fig. 3, described evaporimeter 10 comprises that a hollow housing 11 and is arranged on the dividing plate 12 in this hollow housing 11, this dividing plate 12 is separated to form an evaporation cavity 14 and a compensated cavity 16 with hollow housing 11 inside, the inner surface of evaporation cavity 14 is provided with capillary structure 18, and this capillary structure 18 passes this dividing plate 12 and extends in the compensated cavity 16.
Described housing 11 is a cylindrical-shaped structure, and it comprises a cylindrical circular leg 120 and two sidewalls 110 that vertically extended internally by these leg 120 opposite ends, and this two sidewall 110 is respectively equipped with a through hole and wears for described pipeline 20.This housing 11 can be made by heat conductivility good metal material, as copper etc.
Described dividing plate 12 is provided with a perforation and passes for described capillary structure 18.The leg 120 of the periphery of this dividing plate 12 and described housing 11 is combined closely.This dividing plate 12 is perpendicular to the leg 120 of described housing 11.In other embodiments, this dividing plate 12 can be not orthogonal to the leg 120 of described housing 11.In the present embodiment, the perforation of this dividing plate 12 is opened in the center of dividing plate.In other embodiments, the perforation of this dividing plate 12 is opened in other positions of this dividing plate 12.
Described evaporation cavity 14 is communicated with described pipeline 20 by a sidewall 110 of described housing 11, and described compensated cavity 16 is communicated with this pipeline 20 by another sidewall 110.Preferably, the axial length of this evaporation cavity 14 is greater than the axial length of compensated cavity 16.The housing 11 and the above-mentioned heat-generating electronic elements thermo-contact at these evaporation cavity 14 places.
Described capillary structure 18 is a vesicular texture, and it can be the combined type capillaries fabricated of sintered powder (sintered powder), minute groove (fine grooves), braiding mesh (mesh), fiber (fiber) or above-mentioned pattern.This capillary structure 18 roughly is cylindric, comprises the discoid base portion 180 that is sticked with described dividing plate 12, from a side periphery vertically extending one tubular peripheral wall portion 182 of this base portion 180 and by the vertically extending extension 184 in these base portion 180 another sides.This wall portion 182 and base portion 180 are attached at the inner surface of described evaporation cavity 14.The perforation that this extension 184 passes described dividing plate 12 is stretched in the described compensated cavity 16, and immerses in the hydraulic fluid that is stored in this compensated cavity 16.The setting of being separated by of this extension 184 and compensated cavity 16 inner surfaces.This base portion 180 forms the blind end of this capillary structure 18, and this wall portion 182 forms the open end near an end of pipeline 20, thereby forms a steam channel 140 in evaporation cavity 14.This steam channel 140 extends axially along capillary structure 18, and is communicated with pipeline 20.The cross-sectional area of this steam channel 140 is greater than the cross-sectional area of pipeline 20, so that the steam that the evaporation of the hydraulic fluid in the evaporation cavity 14 back produces enters in the pipeline 20.
