As a preference, the evaporating end includes two parts: the pipeline from the evaporating end to the condensing end (the descending section) 9 and the ascending section. Among them, as a preference, a pipeline 10 from the condensing end to the evaporating end is provided in the ascending section.

As shown in Figure 1, a loop heat pipe air water intake device includes a fan device 1, an air inlet channel 5, an air outlet channel 4, a loop heat pipe and a water storage condensation chamber 7, and the water storage condensation chamber 7 is arranged in the soil In the cold source, the loop heat pipe is an anti-gravity heat pipe, the outlet of the air inlet channel 5 and the inlet of the air outlet channel 4 communicate with the water storage condensation chamber, and the fan device 1 introduces air from the air inlet channel 5 to the water storage The condensation chamber 7 exchanges heat with the evaporation end 6 during the process, and the condensation end 8 conducts heat to the external soil cold source.

The invention provides an air water intake device of a loop heat pipe with a new structure. By setting the loop heat pipe as a high-efficiency heat transfer tool, the principle is simple, the structure is compact, and the cooling efficiency is significantly improved. Moreover, the present invention utilizes the temperature difference between the above-ground air and the underground soil to force the moist air to reach the dew point, thereby getting rid of the dependence on electricity, and can truly achieve zero emission and zero pollution.

Preferably, at least a part of the evaporation end 6 of the loop heat pipe is installed at the entrance of the water storage condensation chamber 7 .

As preferably, the condensing chamber 7 inlet pipe is set between the condensing chamber 7 and the fan device 1, at least a part of the air inlet channel 5 is arranged in the condensing chamber 7 inlet pipe, and at least a part of the condensing chamber 7 inlet pipe is arranged in the external soil In cold source. With such setting, the air in the air inlet channel 5 can directly participate in the heat exchange of the external soil cold source, so that the air can be further cooled under the joint action of the soil and the loop heat pipe, and the cooling effect can be improved.

Further preferably, the fan device 1 includes a vertical wind turbine, a planetary gear speed-up 2 and a helical blade 3 , and the vertical-axis wind turbine uses wind energy to drive the planetary gear speed-up 2 and the helical blade 3 to inhale air.

Preferably, the vertical wind turbine 1 is located at the top, and the lower part is followed by a planetary gear speed increaser 2 and a helical blade 3 , and the helical blade 3 communicates with the inlet pipe of the condensation chamber 7 so as to introduce external air into the condensation chamber 7 .

Further preferably, the inlet pipe of the condensation chamber 7 is the air inlet channel.

Preferably, as shown in FIG. 1 , the diameter of the water storage condensation chamber 7 is downward from the position where the inlet pipe is connected, and the diameter gradually increases at the beginning, and then the diameter gradually decreases after reaching a certain position. It is conducive to the flow of air in the condensation chamber, completes the gas cycle, and increases the heat exchange efficiency between the gas and the condensation chamber wall

Preferably, the evaporation end 6 of the loop heat pipe is installed at the inlet pipe of the water storage condensation chamber, and the condensation end 8 of the loop heat pipe is wound outside the condensation chamber to directly contact the external soil. The loop heat pipe condenser is wound outside the condensation chamber and fully contacts with the external soil to increase the heat dissipation of the air at the evaporating end of the heat pipe and improve the cooling efficiency.

Preferably, a capillary wick 13 is provided in at least a part of the evaporating end 6, and its capillary force provides the power for the reflux cycle of the working fluid, and at the same time makes the reflux working fluid meet the heat transfer requirements, thereby realizing the function of an anti-gravity heat pipe.

By setting capillary wick 13, because capillary wick 13 itself is set at the evaporating end, flow resistance is naturally generated in the ascending section 6 of the evaporating end, so that the steam generated at the evaporating end naturally flows to the pipeline 9 with small resistance, thereby forming an anti-gravity heat pipe .

Preferably, the capillary wick 13 is only arranged in the ascending section of the evaporation end, preferably in a part of the ascending section. For example, as shown in Figure 6 and Figure 10.

Preferably, at least a part of the air outlet channel 4 is arranged in the inlet pipe of the condensation chamber, and the cold air at the air outlet precools the hot air at the air inlet. Through the heat exchange between the outlet gas and the inlet gas, the heat exchange effect is further realized and the condensation efficiency of water is increased.

As preferably, as shown in Figure 7, the evaporating end is arranged at the inlet pipe of the condensing chamber, and the rising section of the evaporating end is filled with a capillary wick 13 to provide sufficient capillary force. , by setting the pipeline 10 in this way (there is no capillary core), the fluid resistance of the pipeline can be reduced, making the working fluid return more smoothly, and improving the heat transfer capacity under the anti-gravity state. The straight fins 12 increase the heat exchange area and improve the heat exchange efficiency with air.

The pipeline 10 is a gas or liquid pipeline, which realizes a flexible arrangement, and has a small diameter and is easy to bend. The principle of the loop heat pipe is that if the side of the evaporator and the pipeline 10 are steam pipelines, the principle is that the internal working medium evaporates when the evaporator is heated, and the steam enters the pipeline 10 along the upper outlet of the evaporator, and then flows to the surrounding pipeline at the lower part. The soil contact begins to condense, and when the steam is completely condensed, it is returned to the evaporator by the capillary force of the evaporator, thereby realizing the circulation of the working fluid.

Preferably, the pipeline 10 communicates with the capillary core 13. Through communication, the circulation of fluid between the capillary wick 13 and the pipeline 10 can be realized, so that when the liquid rises through the capillary wick, if a large pressure is generated due to heat absorption, for example, bubbles may even appear, it can pass through the pipeline. 10 to balance the pressure of the evaporation section, so as to ensure the balance of pressure.

Further preferably, the capillary wick 13 extends to the condensing end, so as to directly suck up the liquid at the condensing end. Further improve the circulation capacity of the anti-gravity heat pipe.

Preferably, the capillary cores are distributed along the height direction, as shown in Fig. 6 . Further preferably, along the height-decreasing direction, the capillary force of the capillary core is gradually enhanced. The closer to the condensation end, the greater the capillary force. It has been found through experiments that this method can further increase the suction force on the liquid, and can increase the suction force by more than 20% at the same cost, thereby improving the heat exchange effect.

Through further analysis, the preliminary reason may be that as the capillary force near the condensing end becomes stronger, the liquid at the condensing end can be quickly sucked into the capillary core, and the liquid continuously flows to the evaporating end. During the flow process, the liquid continuously absorbs heat, and the temperature rises due to the heat absorption, and the density becomes smaller. Therefore, due to the change in density, the capillary force required by it becomes significantly smaller. Sucks up easily. The above reasons are obtained by the inventor through a large number of experiments and researches, and are not common knowledge in this field.

Further preferably, along the height-decreasing direction, the capillary force of the capillary wick is gradually enhanced to a greater extent. It has been found through experiments that this method can further increase the suction force on the liquid, and can further increase the suction force by about 8% at the same cost, thereby improving the heat exchange effect.

Preferably, the pipeline is formed by a through hole opened in the middle of the capillary core.

Preferably, as shown in FIG. 10 , the tube diameter at the position of the heat pipe with the capillary core is larger than the tube diameter at the position of the heat pipe without the capillary core.

Further preferably, as shown in FIG. 10 , the change in diameter between the tube at the heat pipe position with the capillary wick and the tube at the heat pipe position without the capillary wick is a continuous change. More preferably, it changes linearly. The pipe at the position of the large pipe diameter and the pipe with the small pipe diameter are connected by a constriction at the joint. The change of the pipe diameter of the shrinkage part is a linear change.

Preferably, the air outlet channel 4 is arranged between two adjacent vertical fins 12 and is in contact with the two adjacent vertical fins 12 . By setting in this way, it is possible to reduce the number of independent mechanisms for supporting the air outlet passage 4, so that the structure is compact, and the cold air in the outlet passage can exchange heat with the fins through the pipes to keep the fins cold and enhance the heat exchange effect.

Preferably, the condensing end pipeline 9 flowing from the evaporating end is arranged between two adjacent vertical fins and is in contact with the two adjacent vertical fins. Through such setting, it is possible to reduce the number of independent mechanisms supporting the air outlet channel 4, making the structure compact, and the steam in the pipeline can transfer a small amount of heat to the fins through the pipeline, reducing the overall thermal resistance of the system and avoiding evaporation when the ground resists gravity The superheating of the steam generated in the device can slow down the temperature oscillation during the start-up of the heat pipe.

Further preferably, the pipeline 9 is closer to the outer wall of the evaporation end pipeline than the air outlet channel 4, so that the above two heat transfer processes can be realized simultaneously and play corresponding roles.

Further preferably, the pipe 9 has a smaller diameter than the air outlet channel 4 .

Preferably, along the condensing end pipeline 9 that can be provided with multiple evaporating end flow directions, as shown in FIGS. 7 and 9 . By arranging a plurality of pipelines 9, the steam generated by absorbing heat at the evaporating end can enter the condensing end through multiple pipelines 9, further enhancing heat transfer, and because the fluid in the heat pipe absorbs heat and evaporates, resulting in an increase in volume, by setting multiple The pipeline 9 can further relieve the pressure and improve the heat exchange effect.

Further preferably, the vertical fins extend through the center of the inlet pipe of the condensing chamber, and the ascending pipeline at the evaporating end has the same center of circle as the inlet pipe of the condensing chamber.

Preferably, there are multiple pipelines 9, and the distance between the centers of the multiple pipelines 9 and the pipeline in the ascending section of the evaporating end is the same.

Further preferably, a pipeline 9 is provided between every two adjacent vertical fins 12 . The pipeline 9 is a parallel structure.

As a preference, there are multiple air outlet passages 4, and the distance between the center of circles of the multiple air outlet passages 4 and the pipeline in the ascending section of the evaporating end is the same, so that the temperature distribution between the fins is more uniform, and the above-mentioned heat exchange The effect is more obvious. Further preferably, an air outlet channel 4 is provided between every two adjacent vertical fins 12 . The air outlet channels 4 are parallel structures.

Further preferably, there are multiple pipelines 9 and multiple air outlet channels 4 , and the number of pipelines 9 is equal to the number of air outlet channels 4 .

Further preferably, the pipelines 9 are arranged between adjacent air outlet channels 4 , and the air outlet channels 4 are between adjacent pipelines 9 . Further preferably, the distance between the center of the pipeline 9 and the center of the adjacent air outlet channel 4 is the same; the distance between the center of the air outlet channel 4 and the center of the adjacent air pipeline 9 is the same. That is, the pipeline 9 is arranged in the middle of adjacent air outlet channels 4 , and the air outlet channel 4 is in the middle of adjacent pipelines 9 . That is, as shown in Figure 8, the first connecting line between the center of the circle where the pipeline 9 is located and the center of the evaporating end 6 forms the first connecting line and the second connecting line between the center of the circle of the adjacent air outlet channel 4 and the center of the evaporating end 6. For three connecting lines, the first angle formed between the first connecting line and the second connecting line is equal to the second included angle formed between the first connecting line and the third connecting line. Similarly, the fourth connecting line between the center of the circle where the air outlet channel 4 is located and the center of the evaporating end 6, the fifth connecting line and the sixth connecting line are formed between the center of the adjacent pipeline 9 and the center of the evaporating end 6, The third included angle formed between the fourth connecting line and the fifth connecting line is equal to the fourth included angle formed between the fourth connecting line and the sixth connecting line. That is, along the circumferential direction, the pipelines 9 and outlet channels 4 are evenly distributed.

Through the above arrangement, it is possible to ensure that the pipeline 9 and the air outlet channel 4 cool the inlet air evenly, and avoid uneven local income, resulting in poor water intake effect.

It has been found in numerical simulations and experiments that the diameter difference between the air outlet channel 4 and the pipeline 9 should not be too large or too small. If it is too large, the distance between the air outlet channel 4 and the pipeline 9 will be too far apart, resulting in a The heat exchange between the air and the pipeline 9 is not good, resulting in uneven overall heat exchange, if it is too small, the distance between the air outlet channel 4 and the pipeline 9 is too close, resulting in the air and/or air close to the outer wall of the air inlet channel 5 Or the heat exchange of the air near the outer wall of the evaporating end 6 is not good, resulting in uneven heat exchange of the air in the overall air inlet channel 5; for the same reason, the angle between adjacent fins 12 should not be too large, otherwise it will As a result, the number of distributed fins is too small, and the heat exchange effect is too poor. At the same time, the number of air outlet channels 4 and pipelines 9 is too small, resulting in uneven heat exchange and poor heat exchange effect. Similarly, between adjacent fins 12 The angle between them should not be too small, if it is too small, the distribution of the fins will be too dense, the flow resistance will be greatly increased, and the diameters of the air outlet channel 4 and the pipe 9 are not much different, but their heat transfer capabilities of the same area are very different , so in this case the heat transfer is not uniform, resulting in poor heat transfer effect. Therefore, it is necessary to determine the optimal size relationship through a large number of numerical simulations and experiments.

The radius of the air outlet channel 4 is R, the radius of the pipeline 9 is r, and the angle between adjacent fins is A, which meets the following requirements:

Sin(A)=a*LN(r/R)+b, where LN is a logarithmic function, a and b are parameters,

Wherein 0.330<a<0.340,0.73<b<0.74;

15°<A<25°;

0.24<r/R<0.5; more preferably, 0.26<r/R<0.38.

The above empirical formula is obtained through a large number of numerical simulations and experiments, and the experimental verification shows that the error is basically within 3.2.

As preferably, said 3<R<10mm; said 1.5<r<4.0mm;

Further preferably, the diameter of the heat pipe at the capillary position is 30-40mm, more preferably 32mm;

Further preferably, the diameter of the heat pipe without a capillary wick is 5.0-6.4mm;

Further preferably, the pipe diameter of the pipeline flowing from the condensation end to the evaporation end is 5.0-6.4mm;

Further preferably, the diameter of the air inlet channel 5 is 80-200mm; preferably, 120-150mm;

Further preferably, the vertical length of the fins is 780-1500 mm, preferably 1200 mm; the longitudinal extension of the fins accounts for 95% of the difference between the outer diameter of the evaporation end 6 and the inner diameter of the air outlet channel 4 . Under this length, the overall heat transfer capacity of the fins is significantly improved, and the heat transfer coefficient is also within an appropriate range, and the influence on the breaking effect of the boundary layer and the fluid flow effect is relatively small.

The external wind drives the vertical axis wind turbine 1 shown in the figure to rotate, and the wind energy is converted into mechanical energy. The wind turbine drives the coaxial air inlet spiral blade 3 to rotate through the planetary gear transmission 2, and sucks the filtered outside humid air into the condensation chamber. The air inlet is designed as a rotary body with a reduction port for maintaining pressure. The continuous operation of the impeller increases the gas pressure in the cavity and increases the absolute humidity of the moist air. Under the continuous action of air pressure, the air with high absolute humidity enters the underground condensation chamber through the relatively narrow air intake channel. The hot air from the outside first exchanges heat with the colder air being discharged to the outside in the air inlet channel 5, so that the exhaust gas can take away part of the heat, and the metal outer wall in contact with the soil also has a heat conduction function, and the two work together to complete the process. The air is pre-cooled. After the air begins to enter the condensation chamber, the hotter air first slowly passes through the fin channel of the loop heat pipe evaporator, and completes heat exchange with the medium in the loop heat pipe, and its own temperature drops significantly. Small droplets form on the surface. The remaining air goes deep into the water storage condensation chamber 7, exchanges heat with the external soil through the metal outer wall of the cavity, and condenses into liquid droplets at the same time. As the liquid water gradually accumulates, the contact area between the hot air and the outer wall gradually decreases. At this time, the main cooling source is provided by the loop heat pipe. The evaporating end 6 of the loop heat pipe absorbs the heat of the hot air, evaporates the liquid working medium into a gaseous state, and then conducts heat to the external soil through the condensing end 8 of the loop heat pipe wound outside the condensation chamber, so that the gaseous working medium is condensed into a liquid state , and the anti-gravity loop heat pipe has the characteristic of being able to make the liquid flow back. Under the continuous wind force, the water resources in the humid air outside will be continuously collected into the water storage condensation chamber, cooled rapidly, and then discharged out after condensing liquid water. The electric energy generated by the vertical axis wind turbine 1 is stored in the storage battery, and the electric energy is supplied to the electronic water pump to pump out the accumulated fresh water and store it in the ground water tank.

When taking water, the present invention uses wind energy, soil cold source and loop heat pipe to condense water vapor in the air to take water, which not only solves the traditional solar adsorption method’s dependence on solar energy, but also adapts to more regions and weather conditions. There is no secondary energy consumption, and the problem that the conversion efficiency of the existing technology is not high enough is solved.

As a preference, the planetary gear speed increaser connects the vertical axis wind turbine and the impeller to amplify the rotational speed transmitted from the wind turbine to the impeller, so that the external air enters the tank faster, increases the air intake to a certain extent, and at the same time improves the air flow in the pipeline. pressure.

Before starting, the capillary core of the evaporator of the loop heat pipe, the supplementary cavity and the infusion tube are filled with working fluid, while the steam channel, condenser and steam tube are in a two-phase state.
