Description

Technical Field

[0001] The utility model relates to the field of dehumidification devices, in particular to an active electrolysis water molecule device and equipment in a limited space. Background Art

[0002] Products and equipment containing electronic components in sealed enclosures, such as smart helmet displays, headlights, surveillance cameras, image detection, lidar sensors, and electrical cabinets for offshore equipment, experience internal temperature increases during operation and decreases during inactivity. In the event of external temperature and humidity fluctuations (such as heavy fog or rain), these sealed enclosures can cause internal humidity and pressure to rise due to these changes. This can lead to fogging, condensation, and expansion and deformation of the enclosure. This can cause insulation failure and short circuits in electronic components, and in severe cases, fires or explosions. This can lead to immeasurable consequences for operators and those near sealed enclosures and equipment, including image signal distortion, misjudgment, poor lighting conditions, and potential safety concerns for property and life.

[0003] To address this issue, various domestic sectors typically use desiccant or heating fans to reduce internal moisture levels. However, due to their low moisture absorption rate, lack of waterproofing, and short lifespan, desiccants require regular drying before use. If exposed to water, they must be replaced. Heating fans consume high current, require waterproofing, and generate a certain amount of noise, making them difficult to meet the requirements of engineering applications.

[0004] Currently, electrolytic components that use the principle of water electrolysis will cause excessively high oxygen concentrations inside smart helmet displays, headlights, monitoring probes, image detection, lidar detection sensors, etc. The oxygen atoms or molecules released by electrolysis will cause rust and poor contact on the internal electrical components and circuits (internal chips, integrated blocks and other electronic components, lines, PI insulation layers, etc.) in an oxygen-rich environment. Continuous electrolysis causes the internal oxygen concentration to accumulate too high, causing the risk of spontaneous combustion; hydrogen accumulation on the cathode side will pose a risk of hydrogen explosion; and its frequent electrical failures make it difficult to meet the user's reliability requirements. Summary of the Invention

[0005] The main technical problem solved by the utility model is to provide an active electrolysis water molecule device and equipment in a limited space, which utilizes the difference in moisture permeability between the ePTFE microporous breathable protective membrane and the continuous one-way moisture-permeable coating membrane to achieve one-way continuous discharge of water vapor from the inside to the external environment, effectively exerting the efficiency of electrolytic dehumidification.

[0006] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide an active water molecule electrolysis device in a limited space, including a shell with an air flow channel, a membrane electrode assembly is provided in the shell, and the membrane electrode assembly separates the air flow channel into an air inlet end and an exhaust end, the air inlet end is provided with a continuous one-way moisture-permeable coating membrane, and the exhaust end is provided with an ePTFE microporous breathable protective film, and the shell is provided with an oxygen exhaust channel that connects the air inlet end with the outside.

[0015] In order to solve the above technical problems, another technical solution adopted by the present invention is: to provide a device having the above active water electrolysis device, wherein the internal space of the device is connected to the air inlet end of the active water electrolysis device.

[0016] The beneficial effects of the present invention are as follows: the active water molecule electrolysis device and equipment within a limited space of the present invention has different moisture permeability due to the difference in the two moisture permeability directions, and utilizes the difference in moisture permeability between the ePTFE microporous breathable protective membrane and the continuous one-way moisture permeable coating membrane to continuously discharge water vapor, and when the temperature inside the shell is higher, the more active the hydrophilic polymer chain segments of the coating are, the faster the speed of adsorption, diffusion and desorption of water vapor molecules is.

[0024] See also Figure 1 and Figure 2 A device for active electrolysis of water molecules within a confined space includes a housing 1 having an air flow channel. A membrane electrode assembly 5 is disposed within the housing 1, which divides the air flow channel into an air inlet end 17 and an air outlet end 18. The anode side of the membrane electrode assembly 5 faces the air inlet end 17, and the cathode side of the membrane electrode assembly 5 faces the air outlet end. An oxygen exhaust channel 16 is provided in the housing 1, connecting the air inlet end 17 to the outside. Oxygen generated during the reaction is discharged through the oxygen exhaust channel 16.

[0025] The air inlet 17 is provided with a continuously one-way moisture-permeable coating membrane 14, and the air outlet 18 is provided with an ePTFE microporous breathable protective membrane 6. The ePTFE microporous breathable protective membrane 6 forms a filtering and breathable protective layer, discharging hydrogen generated by cathode electrolysis and water molecules formed by the catalyst and atmospheric oxygen. It also prevents rainwater, dust, and oil from the external environment from entering the cathode cavity, protecting the cathode and catalyst layer from the risk of external environmental contamination. This extends the life of the electrolysis device and effectively maximizes the efficiency of electrolytic dehumidification.

[0026] The continuous one-way moisture-permeable coating film 14 adopts a polyurethane emulsion coating agent (see patent CN103862728B for details). The polyurethane molecular structure contains a high molecular compound containing -NHCOO- units. Its main principle is to introduce an appropriate amount of hydrophilic groups into the polymer chain, which spontaneously disperses under certain conditions to form an emulsion. The PU macromolecule contains a large number of polar groups and the intermolecular force is very strong, resulting in it having excellent film-forming properties and being able to form a tough and durable film on the fabric. It also has certain moisture permeability. The reason for this is that, on the one hand, polar or hydrophilic groups in PU, such as -OH, -NHCOO-, -COOH, and silicone micropowder, act as "chemical stepping stones," allowing water vapor molecules to migrate along the steps from the high-humidity side to the low-humidity side. Theoretically, polymer chains primarily contain hydrophilic groups, and as long as the content and arrangement of these groups are appropriate, they can interact with water molecules. Through hydrogen bonds and other intermolecular forces, water is adsorbed on the high-humidity side and then transferred to the low-humidity side for desorption via the hydrophilic groups on the polymer chain. Therefore, moisture permeability is essentially a process of "adsorption-diffusion-transfer-desorption." The hydrophilic groups are called "chemical stepping stones." Under a pressure differential, water is transferred directionally from one side to the other. This process is known as unidirectional moisture permeability.

[0027] The continuous one-way moisture-permeable coating film 14 is a coating agent containing a hydrophilic group of polyurethane emulsion rolled on the surface of one side of the expanded polytetrafluoroethylene membrane. The coating is dried at a temperature of 80°C to 100°C and stored at room temperature for 24 hours. The coating is solidified on the surface of the expanded polytetrafluoroethylene membrane to form a dense and durable coating. The coating contains hydrophilic groups and interacts with water molecules. With the help of hydrogen bonds and other intermolecular forces, it absorbs water on the high humidity side and then transfers it to the low humidity side for desorption through the hydrophilic groups on the polymer chain. Therefore, moisture permeability is essentially a process of "adsorbing" water vapor molecules on the surface of the hydrophilic polyurethane coating, "diffusing" the water molecules from within the hydrophilic polyurethane coating to the outside, "desorbing" the water molecules at the interface between the hydrophilic polyurethane coating and the expanded polytetrafluoroethylene membrane, and then "entering" the dense micropores of the expanded polytetrafluoroethylene membrane and discharging moisture to the external environment. The hydrophilic groups are called "chemical stepping stones." Under the presence of a pressure difference, trace moisture is transferred directionally from the high-concentration side to the low-humidity side. This process is also called unidirectional moisture permeability.

[0028] Extensive testing of the continuously unidirectionally permeable coating film 14 revealed that the rate of water vapor dissipated from the coating side toward the expanded polytetrafluoroethylene membrane side is greater than the rate of water vapor dissipated from the expanded polytetrafluoroethylene membrane side toward the coating side. This difference in the two permeation directions results in a difference in moisture permeability: the rate of moisture dissipated from the coating side outward is approximately 30% greater than the rate of moisture dissipated from the expanded polytetrafluoroethylene membrane side into the housing 1. Leveraging this significant difference in moisture permeability between the two directions, the coating film was applied to electrical (automotive) electronic equipment, with the coating side of the coating film facing the automotive electrical (automotive) electronic equipment and the expanded polytetrafluoroethylene membrane of the coating film facing the external atmosphere. This allows water vapor to be continuously discharged from the housing of the electrical (automotive) electronic equipment, demonstrating the characteristic of unidirectional, continuous water vapor dissipation from the interior of the housing 1 to the external environment. When the electrical (automotive) electronic equipment is operating and the temperature within the housing 1 is high, the hydrophilic polymer segments of the coating become more active, resulting in faster adsorption, diffusion, and desorption of water vapor molecules.

[0029] The continuous one-way moisture-permeable coating membrane 14 has the function of one-way moisture permeability but not air permeability. The function of the continuous one-way moisture-permeable coating membrane 14 is that the anode electrolysis chamber is separated by the continuous one-way moisture-permeable coating membrane 14 into a chamber connected to the external atmospheric environment. The water molecules in the separated anode chamber are electrolyzed under the action of the platinum-carbon catalyst on the anode side to release oxygen atoms or molecules, hydrogen protons and electrons, etc.; the oxygen atoms or molecules released by electrolysis are continuously released to the external atmospheric environment through small pores. The separated anode chamber presents a micro-positive pressure dry environment with very low humidity under the action of the electrolysis function. The water molecules in the humid and hot air inside the smart helmet display, car lights, monitoring probes, image detection, lidar detection sensors, etc. migrate, penetrate, diffuse and desorb to the anode chamber through the one-way moisture-permeable coating membrane to be electrolyzed. (Moisture permeability is essentially a process of "adsorption-diffusion-transfer-desorption". The hydrophilic group is called a "chemical stepping stone". In the presence of a pressure difference, trace moisture is directed from the high concentration side to the wet side. The moisture is then transferred to the other side with a lower humidity. This process is also known as a one-way moisture permeation process. The continuously one-way moisture-permeable coating film 14 has the function of being one-way moisture-permeable but air-tight, protecting the electrical components and circuits contained therein from corrosion damage caused by oxygen-rich atoms. The internal oxygen concentration level is maintained at the same level as the atmospheric concentration, avoiding the risk of spontaneous combustion caused by excessive oxygen concentration. The trace moisture content in the air inside the coating film is continuously reduced by the electrolysis device, and the humidity value continues to decrease, keeping the interior dry. Even in the low dew point of the external environment, the smooth mirror surfaces of the smart helmet display, headlights, monitoring probes, image detection, LiDAR detection sensors, etc. will not fog or condense. This is an important new and significant innovation of the device. This protects the electronic components, circuits, PI insulation layers, and chips, integrated circuits, etc. within the smart helmet display, headlights, monitoring probes, image detection, LiDAR detection sensors, etc. from corrosion in oxygen-rich environments, resulting in more reliable electrical performance, lower failure rates, and longer lifespan.

[0030] The outer side of the shell has an external thread for installing the membrane electrode assembly 5 and connecting to equipment such as smart helmet displays, car lights, monitoring probes, image detection, lidar detection sensors, etc. A through-hole cover plate 4 is provided on the exhaust end 18, and the through-hole cover plate 4 and the shell bracket can be fixed by welding or gluing. The ePTFE microporous breathable protective membrane 6 is arranged on the end face of the cover plate. A PET protective layer 7 with through holes is also bonded to the outside of the ePTFE microporous breathable protective membrane 6, and the two brackets can be connected by an adhesive. The PET protective layer 7 with through holes can increase the strength of the ePTFE microporous breathable protective membrane 6.

[0031] The elastic sealing ring 3 compresses the membrane electrode assembly 5, so that the conductivity of the electrolysis circuit of the device is better. The membrane electrode assembly 5 includes a conductive carbon paper diffusion layer 8, a cathode catalyst layer 9, a proton exchange membrane 10, an anode catalyst layer 11 and an anode porous foil 12 arranged in sequence. The cathode catalyst layer 9 is a cathode platinum carbon Pt / C catalyst layer, the proton exchange membrane 10 is a perfluorosulfonic acid proton exchange membrane or a perfluorosulfonic acid proton exchange membrane reinforced with an ePTFE microporous membrane, the anode catalyst layer 11 is an anode platinum carbon Pt / C catalyst layer, and the anode porous foil 12 is an anode platinum titanium Pt / Ti porous foil. A DC anode conductor 15 and a DC cathode conductor 13 are also provided in the housing. The DC anode conductor 15 is connected to the anode platinum titanium Pt / Ti porous foil, and the DC cathode conductor 13 is connected to the conductive carbon paper diffusion layer 8. The DC anode conductor 15 and the DC cathode conductor 13 form a conductive electrolysis reaction circuit.

[0032] The conductive carbon paper diffusion layer 8 is an electrolytic circuit conductor having microporous through-holes, through which hydrogen generated by cathode electrolysis and water molecule gas synthesized by the catalyst and oxygen in the atmosphere are diffused and discharged.

[0033] The cathode platinum carbon Pt / C catalyst layer is the cathode side catalyst layer. H + Under the action of DC voltage, H+ flows through the perfluorosulfonic acid proton exchange membrane or the perfluorosulfonic acid proton exchange membrane reinforced with ePTFE microporous membrane to reach the cathode side. Under the action of the platinum-carbon catalyst on the cathode side, H+ undergoes the following reaction to generate hydrogen molecules or water molecules:

[0034] 4H + +4e—2H2, O2+4H + +4e - —2H2O; H + The platinum-carbon catalyst on the cathode side reacts to produce hydrogen or water molecules, which are then released into the external atmosphere through the ePTFE microporous membrane and the external atmosphere through smart helmet displays, headlights, monitoring probes, image detection, and lidar sensors. This results in an extremely low hydrogen concentration on the cathode side, which is safe.

[0035] Perfluorosulfonic acid proton exchange membrane or perfluorosulfonic acid proton exchange membrane reinforced with ePTFE microporous membrane is H + Under the action of the electric field force formed by the voltage between the anode and the cathode, H + Conducted to the cathode side, the proton exchange membrane 10 only allows H + By blocking the passage of electrons, electrons flow through the DC power supply through the conductor circuit, forming a closed conductive system loop.

[0036] Perfluorosulfonic acid proton exchange membrane or perfluorosulfonic acid proton exchange membrane reinforced with ePTFE microporous membrane electrolyzes water molecules in the internal space of smart helmet displays, car lights, monitoring probes, image detection, lidar detection sensors, etc. to reduce their internal humidity. Even under very low dew point conditions, no fogging and condensation will occur because the cause of fogging and condensation is caused by the internal trace moisture humidity. The innovative structure of the device uses a proton exchange membrane 10 with good chemical stability, proton conductivity, and gas separation as a solid electrolyte, which can effectively prevent electron transfer. The oxygen atoms electrolyzed at the anode are continuously released to the external atmospheric environment through small pores, eliminating the oxygen atoms and oxygen hazards generated by the electrolysis in the anode chamber. The hydrogen atoms electrolyzed at the cathode and the synthesized water molecules and hydrogen are diffused by convection with the external air through the ePTFE microporous breathable protective membrane 6, eliminating the explosive hazard of hydrogen accumulation in the cathode chamber. The innovative structure of the device improves the safety of the electrolysis device and engineering applications.

[0037] The anode platinum carbon Pt / C catalyst layer is the anode catalyst layer 11. The water molecules in its internal space move at high speed and irregularly. Some of them collide with the anode side platinum carbon catalyst and the platinum titanium conductive network to cause electrolysis reaction. The electrolytic decomposition reaction equation of water molecules under the action of the anode side platinum carbon catalyst is: 2H2O-O2+4H + +4e - , oxygen atoms or molecules, hydrogen protons and electrons released by electrolysis.

[0038] The housing also includes an elastic sealing ring 3 and an insulating seal 2 that cooperate with the DC anode conductor 15 and the DC cathode conductor 13. The insulating seal 2 prevents humidity from the external atmosphere from penetrating into the smart helmet display, headlights, monitoring probes, image detection, lidar detection sensors, etc.

[0039] The anode platinum titanium Pt / Ti porous foil mesh enhances the efficiency of catalytic electrolysis of water molecules at the anode and increases the area of ​​the anode where the water molecules collide with the movement of the anode and the chance of the water molecules being electrolyzed.

[0040] The device is assembled and connected with the intelligent helmet display, headlights, monitoring probes, image detection, laser radar detection sensors, etc. The connection methods can be various types such as threaded connection, flange screw connection or bayonet installation. A DC voltage of 1.23V to 3V is applied to the anode and cathode of the device. The water molecules in the internal space of the intelligent helmet display, headlights, monitoring probes, image detection, laser radar detection sensors, etc. move at high speed and irregularly. Some of the water molecules collide with the platinum-carbon catalyst on the anode side and the platinum-titanium conductive network to cause electrolytic reaction. The electrolytic decomposition reaction equation of water molecules under the action of the platinum-carbon catalyst on the anode side is:

[0041] 2H2O—O2+4H+ +4e - , oxygen atoms or molecules, hydrogen protons and electrons released by electrolysis;

[0042] Under the action of the platinum-carbon catalyst on the anode side, water molecules release oxygen and its oxygen atoms into the anode chamber, and the oxygen atoms are continuously released to the external atmospheric environment through small pores. The continuous one-way moisture-permeable coating membrane 14 has the function of one-way moisture-permeable but not air-permeable. The function of the continuous one-way moisture-permeable coating membrane 14 is that the anode electrolysis chamber is separated by the continuous one-way moisture-permeable coating membrane 14 into a chamber connected to the external atmospheric environment. The water molecules in the separated anode chamber are electrolyzed under the action of the platinum-carbon catalyst on the anode side to release oxygen atoms or molecules, hydrogen protons and electrons, etc.; the electrolysis releases The oxygen atoms or molecules released are continuously released to the external atmosphere through the small pores. The separated anode chamber presents a micro-positive pressure dry environment with very low humidity under the action of electrolysis. The water molecules in the hot and humid air inside the smart helmet display, car lights, monitoring probes, image detection, laser radar detection sensors, etc. migrate to the anode chamber through the one-way moisture permeable coating membrane, permeate, diffuse and desorb to the anode chamber to be electrolyzed. (Moisture permeability is essentially a process of "adsorption-diffusion-transfer-desorption". The hydrophilic group is called "chemical stepping stone". Under pressure differentials, trace moisture migrates directionally from the side with higher concentration to the other side with lower humidity. This process is also known as unidirectional moisture permeability. The continuously unidirectional moisture-permeable coating film 14 provides unidirectional moisture permeability while remaining airtight. This protects the electrical components and circuits contained within it from corrosion damage caused by oxygen-rich atoms, maintaining the internal oxygen concentration at the same level as the atmosphere and avoiding the risk of spontaneous combustion caused by excessive oxygen concentration. The electrolysis device also continuously reduces the trace moisture content in the air within, lowering the humidity and maintaining a dry interior. Even in low dew points, the smooth surfaces of smart helmet displays, headlights, surveillance cameras, image detection, and lidar sensors remain free of fogging and condensation. This is a significant new innovation of the device. This protects the chips, integrated circuits, and other electronic components, circuits, and PI insulation layers within these smart helmet displays, headlights, surveillance cameras, image detection, and lidar sensors from corrosion in oxygen-rich environments, resulting in more reliable electrical performance, lower failure rates, and longer lifespans. The H+ generated by electrolysis under the action of the platinum-carbon catalyst on the anode side flows through the perfluorosulfonic acid proton exchange membrane or the perfluorosulfonic acid proton exchange membrane reinforced with ePTFE microporous membrane under the action of DC voltage to reach the cathode side. Under the action of the platinum-carbon catalyst on the cathode side, the H+ undergoes the following reaction to generate hydrogen molecules or water molecules:

[0043] 4H + +4e—2H2, O2+4H + +4e - —2H2O; H +The platinum-carbon catalyst on the cathode side reacts to produce hydrogen or water molecules, which are then released into the external atmosphere through the ePTFE microporous membrane and the external atmosphere through smart helmet displays, headlights, monitoring probes, image detection, and lidar sensors. This results in an extremely low hydrogen concentration on the cathode side, which is safe.

[0044] A device comprises the above-mentioned active water molecule electrolysis device, wherein the internal space of the device is communicated with the air inlet end 17 of the active water molecule electrolysis device.

[0045] The active water molecule electrolysis device in a limited space of the present invention maintains the internal oxygen concentration level at a low state, and the electrical components and circuits installed therein are protected from corrosion damage by oxygen-rich atoms and the risk of spontaneous combustion caused by excessive internal oxygen concentration; the trace moisture content in the air inside the shell is also continuously reduced under the action of the electrolysis device, and the humidity value continues to drop, and the interior is kept in a dry state. Even if the dew point of the external environment is very low, there is no fogging and condensation on the smooth mirror surfaces of the smart helmet display, headlights, monitoring probes, image detection, laser radar detection sensors, etc. This is an important new and major innovative aspect of the device, which prevents the internal chips, integrated blocks and other electronic components, circuits, PI insulation layers, etc. of the smart helmet display, headlights, monitoring probes, image detection, laser radar detection sensors, etc. from corrosion in the oxygen-rich environment, and their electrical performance is more reliable, the failure rate is lower, and the service life is longer. In addition, the cathode chamber of the device uses an ePTFE microporous breathable protective membrane, which on the one hand forms a breathable protective layer with atmospheric convection filtration, continuously discharging the hydrogen electrolyzed by the cathode and the water molecule gas synthesized by the catalyst and oxygen in the atmosphere, eliminating the risk of hydrogen explosion caused by hydrogen accumulation on the cathode side; on the other hand, it prevents rainwater, dust, oil and other pollutants in the external environment from entering the cathode cavity, protecting the cathode and catalyst layer from the risk of external environmental pollution, making the life of the electrolysis device longer and effectively exerting the efficiency of electrolytic dehumidification.

[0046] This invention will provide a new device to eliminate the hazards of fogging and condensation for my country's new energy vehicles, intelligent driving, safety control and monitoring, etc., which will be conducive to improving the competitiveness of new energy vehicles, intelligent driving, safety control and other aspects, making new energy vehicles, intelligent driving, safety control and other aspects safer and more reliable, and with a longer maintenance-free life. Therefore, the company will achieve good economic and social benefits from this invention.
