By further analyzing, preliminary reason may be as the capillary force close to condensation end is increasing, so that condensation The liquid at end can be quickly drawn onto capillary wick, and liquid is constantly flowed to evaporation ends.In flow process, liquid is not Disconnected heat absorption, then because temperature caused by absorbing heat increases, density becomes smaller, therefore because of variable density reason, the hair for needing it Thin power obviously becomes smaller, therefore is also easy for up inhaling in the case where capillary force is small.Above-mentioned reason is that the present inventor passes through What a large amount of experiment and research obtained, the common knowledge of non-this field.
Further preferably, along height descent direction, the amplitude that the capillary force of the capillary wick gradually increases is increasing. It is found through experiments that, takes such mode, the suction to liquid can be further increased, it can be further under identical cost The suction for improving 8% or so, to improve heat transfer effect.

Preferably, air outlet passage 4 is arranged between the vertical fin 12 of adjacent two and erects with adjacent two Straight fins 12 contact.Pass through such setting, it is possible to reduce the mechanism of the independent support air outlet passage 4 of setting, so that structure Compact, the cold air of exit passageway can be exchanged heat by pipeline and fin, kept the cold degree of fin, enhanced heat transfer effect.
Preferably, evaporation ends flow direction condensation end pipeline 9 be arranged between the vertical fin of adjacent two and with it is adjacent Two vertical fin contacts.Pass through such setting, it is possible to reduce the mechanism of the independent support air outlet passage 4 of setting makes Must be compact-sized, the steam in pipeline can reduce system overall thermal resistance, avoid on ground by pipeline to the of short duration a small amount of heat transfer of fin Steam superheating is generated in the case of the antigravity of face in evaporator, to slow down the temperature oscillation phenomenon in heat pipe start-up course.
Further preferably, the pipeline 9 than air outlet passage 4 closer to the outer wall of evaporation ends pipeline so that above-mentioned Two diabatic processes can be achieved at the same time, and play respective action.
Further preferably, the diameter of the pipeline 9 is less than air outlet passage 4.
Preferably, along the condensation end pipeline 9 that multiple evaporation ends flow directions can be set, as shown in Fig. 7,9.Pass through setting Multiple pipelines 9 can make evaporation ends inhale thermogenetic steam and enter condensation end by multiple pipelines 9, further augmentation of heat transfer, And the evaporation because the fluid in heat pipe absorbs heat, cause volume to increase, by the way that multiple pipelines 9 are arranged, can further alleviate pressure Power improves heat transfer effect.
Further preferably, the vertical fin extends through the center of circle of the inlet tube of condensation chamber, the evaporation ends ascent stage The inlet tube of the pipeline and condensation chamber center of circle having the same.
Preferably, the pipeline 9 be it is multiple, between the center of circle and evaporation ends ascent stage pipeline of the multiple pipeline 9 Apart from identical.

Further preferably, 5 caliber of air inlet passageway is 80-200mm;It is preferred that 120-150mm;
Further preferably, the vertical direction length of fin is 780-1500mm, preferably 1200mm;The length that fin longitudinally extends Degree accounts for the 95% of 6 outer diameter of evaporation ends and 4 internal diameter difference of air outlet passage.The overall heat exchange ability of fin significantly mentions under this length Height, the coefficient of heat transfer are and relatively small to the effect of the broken ring in boundary layer and the influence of fluid flow effect also in suitable range.
External wind drives vertical axis windmill 1 as shown in the figure to rotate, and wind energy transformation is mechanical energy.Wind energy conversion system passes through planetary gear Speed changer 2 drives coaxial air inlet helical blade 3 to rotate, and filtered extraneous humid air is sucked condensation chamber.Air inlet air port design It is the revolving body with decrement mouth for maintaining pressure.The continued operation of impeller increases intracavity gas pressure, humid air it is exhausted Humidity is increased.The biggish air of absolute humidity is entered under the continuous action of air pressure by the relatively narrow inlet channel of bore Underground condensation chamber.Extraneous hot-air first in the inlet channel 5 with outdoor cooler air is being discharged into outlet passageway It exchanges heat, exhaust gas is allowed to take away partial heat, the metal outer wall contacted with soil also has thermally conductive function, and the two collective effect is completed Air precooling.After air initially enters condensation chamber, relatively warm air first slow transits through loop heat pipe evaporator fin channels, with loop Medium completes heat exchange in heat pipe, and own temperature significantly reduces, and when reaching dew point, vapor starts to liquefy, in fin surface shape At droplet.Surplus air gos deep into water storage condensation chamber 7, by cavity metal outer wall and extraneous soil heat exchange, while being condensed into liquid Drop.As liquid water is built up, hot-air is gradually decreased with outer wall contact area, and major refrigeration is mentioned by loop circuit heat pipe at this time For.The evaporation ends 6 of the loop circuit heat pipe absorb the heat of hot-air, and liquid refrigerant is flashed to gaseous state, then passes through condensation chamber Heat is conducted to external soil by the loop circuit heat pipe condensation end 8 being externally wrapped with, and gaseous working medium is made to be condensed into liquid, and anti-gravity ring Road heat pipe has the characteristics that liquid reflux can be made.Under lasting wind-force, the water resource in extraneous humid air will be constantly It is collected into water storage condensation chamber, is cooled rapidly, be discharged away after being condensed out liquid water.What vertical axis windmill 1 generated Electric energy is stored in battery, and electric energy supplies the fresh water of electronic water pump extraction accumulation, and storage is on the ground in water tank.
The present invention condenses to water vapor in air by wind energy, soil heat sink and loop circuit heat pipe when fetching water Condensation water intaking, not only solves dependence of traditional solar energy absorption method to solar energy, adapts to more regions and weather condition, accomplish No secondary energy sources consumption, also solves the not high enough problem of prior art transfer efficiency.
Preferably, wind energy conversion system, is transferred to the revolving speed of impeller by planetary gear speed increaser connection vertical axis windmill and impeller Amplification, makes outside air enter tank interior faster, increases intake to a certain extent, while improving the pressure in pipeline.
Preferably, preparing loop heat pipe capillary core using powder metallurgy process.Before starting, the evaporator of loop circuit heat pipe It is full of working medium in capillary wick, additional cavity and perfusion tube, and is in two phases in steam channel, condenser and steam pipe.
Cooling chamber position using soil it is cooling supplemented by, the collaboration heat exchange mode based on anti-gravity loop circuit heat pipe, can mention significantly High-altitude air cooling speed improves water yield.
Preferably, loop circuit heat pipe condensation end is wrapped in outside condensation chamber, increase heat dissipation area.
Preferably, exhaust pipe is placed in the intake channel, to achieve the purpose that air precooling.
Although the present invention has been disclosed in the preferred embodiments as above, present invention is not limited to this.Any art technology Personnel can make various changes or modifications, therefore protection scope of the present invention is answered without departing from the spirit and scope of the present invention When being defined by the scope defined by the claims..
