Description

Technical Field

[0001] This invention relates to a dual-mode all-weather air water intake device, belonging to the field of air water intake technology. Background Technology

[0002] Western my country boasts a vast territory and abundant natural resources such as solar and wind energy, with immense development potential. However, the Northwest region, located deep inland and far from the ocean, is further hampered by high mountains, resulting in an extremely arid climate. The average annual rainfall is only 235 mm, with inland river basins typically receiving less than 200 mm, while evaporation from water surfaces reaches 1000-2800 mm. This combination of low rainfall and high evaporation makes water scarcity in the Northwest far greater than in other parts of the country, severely limiting the drinking water supply for people in some areas. Since directly obtaining potable water is not feasible, the possibility of capturing and purifying atmospheric water vapor for indirect drinking water production could alleviate the long-standing drinking water problem in the Northwest. However, currently available air-based water extraction devices are ill-suited to the Northwest's energy supply and operating environment; most require relatively high humidity to function effectively. If the abundant sunshine and windy, cloudless nature of the Northwest region can be utilized, and combined with solar thermal, photovoltaic conversion and radiative cooling modules, the working efficiency of the air-water intake device will be effectively improved. This working mode, which is in line with the environmental characteristics of the Northwest region, will greatly reduce energy consumption and environmental pollution.

[0003] The patent application document publication number CN218814046U discloses a high-efficiency and energy-saving direct drinking air water extraction device. The device has a complex internal structure, requires a large amount of energy input to operate, is not suitable for outdoor use, and the refrigerant used will cause pollution and is not environmentally friendly.

[0004] The patent application document publication number CN215290380U discloses a renewable energy-driven air water collection device that uses only solar energy as the energy source for the condensation module and cannot work at night. Summary of the Invention

[0026] Specific implementation method one: Combining Figures 1 to 5This embodiment describes a dual-mode all-weather air-water intake device for radiative cooling / semiconductor cooling, comprising two dual-mode working areas 1, a straight rod push-pull system 2, a sleeve, a double-rod piston cylinder 4, a water purification filter element 5, a fixed bracket 6, a water storage chamber 7, a water receiving chamber 8, a solid base 10, and a main body 14. The two dual-mode working areas 1 are horizontally symmetrically arranged. The upper end of the straight rod push-pull system 2 is rotatably connected to the inner edge of the two dual-mode working areas 1. The straight rod push-pull system 2 is inserted into the sleeve. The inner wall of the sleeve is provided with hydrophobic microgrooves 3. The lower end of the straight rod push-pull system 2 is connected to the piston of the double-rod piston cylinder 4. The double-rod piston cylinder 4 is fixedly installed on the upper end of the fixed bracket 6. The lower end of the sleeve is connected to the upper end of the fixed bracket 6. The main body 14 is fixedly installed on the solid base 10. The fixed bracket 6, the water storage chamber 7, and the water receiving chamber 8 are arranged sequentially from top to bottom within the main body 14. The water purification filter element 5 is arranged within the fixed bracket 6.

[0027] In this embodiment, timed contraction squeezes out the water collected in the PDMS sponge and deposits it into the composite micro-groove for collection. Simultaneously, water collected by the corrugated fins also flows into the micro-groove and is collected together due to the combined effects of vibration and gravity.

[0028] In this embodiment, the water and water purification systems are integrated. The upper layer is the purification chamber, using a combination of PP cotton and activated carbon as the purification filter element, which only needs to be replaced periodically. After water flows through the filter element, it enters the water collection chamber. The lower side wall of the water collection chamber has an opening, serving as a faucet for external water intake. The bottom of the water collection chamber has an inverted frustum structure for settling impurities. A piston is installed at the bottom of the frustum; opening the piston periodically releases impurities. The activated carbon includes wood-based activated carbon, powdered activated carbon, fruit shell activated carbon, coconut shell activated carbon, etc.

[0029] The radiation cooling material and the semiconductor cooling plate are connected by corrugated fins 13, which concentrate the cooling at both ends on the fins to form a dual-mode working area.

[0030] The dual-rod piston cylinder 4 is normally in a stretched state, and contracts once per hour to squeeze out the water accumulated in the two PDMS materials on the left and right sides. The water collected on the fins in the middle of the working area tilts and flows out of the device under the action of gravity and vibration. The water from both areas flows into the hydrophobic micro-channels and enters the water purification filter element under the action of drainage.

[0031] Specific Implementation Method Two: Combining Figures 1 to 5 This embodiment describes a dual-mode working area 1 of a dual-mode all-weather air water intake device with radiative cooling and semiconductor cooling. Each dual-mode working area 1 consists of a main body I and multiple corrugated fins 13. The upper layer of the main body I is provided with radiative cooling material, and the lower layer of the main body I is provided with a semiconductor cooling chip. The lower surface of the radiative cooling material is connected to the upper surface of the semiconductor cooling chip through multiple corrugated fins 13.

[0032] A corrugated fin structure is designed between the radiative cooling material and the cold end of the semiconductor cooling body to collect the cold water from both materials on the fins, forming a second condensation module.

[0033] The design of the corrugated fin 13 is to allow the pre-condensed gas to collide more with the condensation surface, increase momentum loss, and promote water vapor nucleation.

Other components and connections are the same as in Embodiment Two.

[0036] Specific implementation method four: Combination Figures 1 to 5 This embodiment describes a dual-mode all-weather air water intake device for radiation cooling / semiconductor cooling.

The surface of the aluminum is also provided with microgrooves, and the surface of the microgrooves is provided with a hydrophobic material. The radiation cooling material layer is made of PDMS sponge, and the semiconductor cooling chip is made of bismuth telluride semiconductor material.

[0037] The main body I is made of aluminum, and the semiconductor cooling chip is made of bismuth telluride N-type and P-type semiconductor materials. By utilizing the Peltier effect, the aluminum plate becomes the cold end.

[0038] PDMS sponge is selected as the radiative cooling material. The high emissivity of PDMS sponge is used for radiative cooling, and the fins are cooled at the lower end of the radiative cooling plate. At the same time, because PDMS sponge has strong water absorption, some moisture will be naturally absorbed and collected at the upper end of the radiative cooling plate.

[0039] The other components and connections are the same as in Specific Implementation Method 2.

[0040] Specific Implementation Method Five: Combining Figures 1 to 5 This embodiment describes a dual-mode all-weather air water intake device for radiation cooling / semiconductor cooling, in which the hydrophilic material is one of aluminum, stainless steel, or glass, and the hydrophobic material is one of polyacrylate or propane-butane.
