Description

Technical Field

[0001] This invention belongs to the field of aluminum-water hydrogen production fuel cell technology, specifically relating to an adaptive thermal stress compensation structure for an aluminum-water hydrogen production reactor. Background Technology

[0002] Existing portable power systems (often called "outdoor power" or "mobile power station") have become indispensable tools in modern life and work. They rely on lithium-ion batteries, solar panels or traditional fuel generators. Therefore, portable individual power supplies based on aluminum-water hydrogen production are more promising due to their advantages of being lightweight and having access to local water sources, without the need to prepare hydrogen cylinders in advance.

[0003] Portable individual power supplies for hydrogen production based on molten aluminum primarily deliver a measured amount of water into a built-in reaction vessel, utilizing the rapid reaction between water and aluminum to produce hydrogen. Because the reaction of molten aluminum releases heat rapidly, the individual power supply needs to dissipate heat from the internal reaction vessel. The following aspects of this heat dissipation process still require improvement: 1. Some manufacturers use external water circulation to cool the reactor, using cold water to absorb heat and eliminate the safety hazards caused by the large amount of heat released during the aluminum reaction. However, the cold water only comes into contact with the outer shell of the reactor and cannot participate in the heat exchange between the outer shell and the inner liner. This may increase the thermal stress between the inner liner and the outer shell, causing the inner liner to crack, bulge, and other potential hazards.

[0004] 2. Some manufacturers also use external air circulation to cool the reactor and recover the heat from the hot air flow for power generation. The recovery of the hot air flow depends on the compressor to concentrate the heat. However, the compressor not only consumes a lot of electricity and is not conducive to the endurance of the power supply, but also has a large size, which is not conducive to the miniaturization of individual power supplies. Summary of the Invention

[0005] The purpose of this invention is to provide an adaptive thermal stress compensation structure for an aluminum-water hydrogen production reactor. By using a mesh cage and an alloy skeleton to pull at intervals, adaptive thermal stress compensation is achieved, resisting the possible deformation caused by thermal stress changes in the aluminum-water reaction.

[0006] The specific technical solution adopted by this invention is as follows: An adaptive thermal stress compensation structure for an aluminum-water hydrogen production reactor includes a reactor vessel and an inner liner shell located inside the reactor vessel, and further includes: A filling and bonding layer is located between the reactor and the inner liner shell, and a first alloy traction component and a second alloy traction component are disposed within the filling and bonding layer; The first, second, and third fibers are connected to the outside of the reactor in a mesh cage, and the mesh nodes of the mesh cage extend into the reactor and connect with the inner liner shell; During hydrogen production, the heat from the inner liner is conducted along the mesh cage to the outside of the reactor. The mesh nodes, the first alloy traction member, and the second alloy traction member are used to reduce the thermal stress between the reactor and the inner liner.

[0007] As an alternative, the first fiber is disposed on both sides of the reactor, and the second fiber is disposed on the other two sides of the reactor; The mesh nodes of the first fiber penetrate the first alloy traction member; The mesh nodes of the second fiber penetrate the second alloy traction element; The first alloy traction component, the first fiber, the second alloy traction component, and the second fiber are all partially embedded inside the inner liner shell.

[0008] As an alternative, the mesh nodes of the third fiber are embedded in the bottom of the inner liner shell in a forked manner; The width of the mesh cage is smaller than the thickness of the filling adhesive layer.

[0009] As an optional solution, the reactor has a first groove on both sides and a first through hole located in the first groove; The first groove is used to accommodate the first alloy traction component and the filler adhesive layer; The mesh nodes of the first fiber penetrate the filling adhesive layer along the first through hole.

[0010] As an alternative, a first buckle for suspending the first alloy traction component is fixed inside the first groove; The mesh nodes of the first fiber bypass the first buckle along the surface of the first alloy traction member.

[0011] As an alternative, the reactor is provided with a second groove on each of its other two sides and a second through hole located inside the second groove; The second groove is used to accommodate the second alloy traction component and the filler adhesive layer; The mesh nodes of the second fiber penetrate the filling adhesive layer along the second through hole.

[0012] As an alternative, a second buckle for suspending the second alloy traction component is fixed inside the second groove; The mesh nodes of the second fiber bypass the second buckle along the surface of the second alloy traction member.

[0013] As an optional solution, the bottom wall of the reactor is provided with a third groove and a third through hole located inside the third groove; The third groove is used to accommodate the filling adhesive layer and the third alloy traction component is fixed in the third groove; The mesh nodes of the third fiber penetrate the third alloy traction member along the third through hole.

[0014] As an alternative, the third alloy traction member is forked and fits onto the fork of the third fiber, and the fork of the third alloy traction member is embedded inside the filling adhesive layer; The projected area of ​​the third alloy traction component on the bottom wall of the third groove is greater than the cross-sectional area of ​​the third groove.

[0015] As an optional solution, the reactor opening is equipped with a removable top cover and a water inlet and an air outlet located on the top cover, with a gap between the inner liner and the top cover; A reinforcing rib is fixed to the outer edge of the reactor opening, and the height of the reinforcing rib is greater than the height of the mesh cage.

[0016] The technical effects achieved by this invention are as follows: In the hydrogen production process of this invention, the heat of the inner liner is conducted to the outside of the reactor along the mesh cage, which accelerates the heat transfer between the reactor and the inner liner. This heat transfer is achieved through the mesh cage, which has a large radiation area and can dissipate heat from the inner liner quickly, thus achieving rapid temperature equilibrium after temperature changes in the reactor and the inner liner. The thermal stress between the reactor and the inner liner is reduced by the mesh nodes combined with the alloy skeleton, thereby reducing the possibility of cracking, bulging and other hidden dangers.

[0017] This invention adds a nickel-based alloy skeleton at the interval, and combines the alloy skeleton with a mesh cage to resist the physical changes caused by thermal stress. The skeleton is tightly wrapped with the mesh cage, which can pull the inner shell at multiple points, assist the inner shell in heat dissipation, accelerate the thermal balance between the reactor and the inner shell, and avoid significantly increasing the volume and weight of the reactor, making it convenient for miniaturization and individual soldier carrying.

[0018] This invention uses an alloy skeleton and a mesh cage to work together to achieve thermal stress compensation, which hardly increases the volume of the reactor. This makes it easy to keep the aluminum-water hydrogen production equipment small and portable for individual soldiers in the field. Attached Figure Description

[0021] To make the objectives and advantages of this invention clearer, the invention will be specifically described below with reference to embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of the invention and does not strictly limit the scope of protection specifically claimed by the invention.

[0022] Existing portable power systems primarily rely on lithium-ion batteries, solar panels, or traditional fuel generators. These systems suffer from drawbacks such as limited energy density, dependence on environmental conditions, high noise levels, and difficulties in fuel transportation. Hydrogen fuel cells, with their advantages of high energy density and stable output, show promising application prospects in portable energy systems. However, most current hydrogen fuel cell systems depend on high-pressure hydrogen storage tanks, which presents challenges such as inconvenient transportation and the risk of explosion.

[0023] Therefore, on-demand hydrogen fuel cells are highly favored by major manufacturers. For example, aluminum reacts with water to produce hydrogen under normal temperature and pressure conditions. Figure 11 The portable aluminum-water hydrogen production individual power supply device shown includes: The hydrogen supply module includes a reactor 1, an aluminum-based alloy material, and the aluminum-based alloy is placed inside the reactor 1. The reactor 1 is made of 316L stainless steel or 2205 duplex stainless steel and can be connected by a detachable device to support multiple replacements of the reaction material. The aluminum-based alloy can react with water in the water tank to produce hydrogen. Water supply module, see Figure 12 The water supply module includes a water storage tank 2, a flow meter, a micro water pump, a level sensor, and a water delivery pipeline. The water storage tank 2 has a volume of 5L and is connected to an external water supply device via a quick-release interface. The water delivery pipeline is equipped with a one-way valve to prevent backflow. The water supply module uses a solenoid valve and a flow meter to achieve quantitative water injection, providing a stable and pure water source for the hydrogen supply module. The level sensor is linked to the control system, triggering an alarm to remind the user to add water when the water level is below a certain height. Among them, the water inlet of water storage tank 2 is equipped with a filter screen, which can filter impurities in the water when collecting water sources in the wild; The oxygen supply module includes a gas booster pump 3, a proportional valve, an air filter, and an oxygen storage tank 4. The air filter installed in the oxygen storage tank 4 can remove dust and impurities from the air to avoid affecting the operation of the fuel cell. The gas booster pump 3 pressurizes the pre-treated air to a certain pressure, and then the proportional valve realizes the air flow to meet the flow requirements of the hydrogen-oxygen fuel cell 6. The hydrogen buffer module includes a hydrogen buffer tank 5 and a drying device. The hydrogen buffer tank 5 stabilizes and buffers the hydrogen produced by the hydrogen supply module, and the drying device dries the hydrogen produced by the hydrogen supply module. The power generation module includes a hydrogen-oxygen fuel cell 6, a lithium battery, and a fuel cell with a rated power of 100W. The hydrogen generated by the reactor 1 and the air delivered by the gas booster pump 3 are introduced into the hydrogen-oxygen fuel cell 6 through a pressure reducing device to generate electricity. During the start-up phase, the lithium battery supplies power to the control system and the gas booster pump 3. During the operation phase, the fuel cell outputs electrical energy to the load and recharges the lithium battery through the system circuit. The control module includes a control device, a solenoid valve, a pressure reducing device, and a pressure sensor. The lithium battery powers the control system during the startup phase. After startup, the water tank 2 begins to inject water into the reactor 1, and the reaction begins to produce hydrogen. At the same time, the gas booster pump 3 starts, and the hydrogen and air are transmitted to the fuel cell at a set flow rate through the pressure reducing device to start generating electricity. The water injection rate and air flow can be dynamically adjusted based on the pressure data from the pressure sensor.

[0024] The working principle of this power supply is as follows: When the power switch is turned on, the control module starts immediately. The control unit sends a signal to first open the solenoid valve of the water storage tank 2, accurately injecting water into the reaction vessel 1, where it reacts with the aluminum-based alloy to generate hydrogen. The generated hydrogen is dried by the drying device and then input into the fuel cell module, where it reacts with oxygen to generate electricity. After the hydrogen and oxygen are stably input, the fuel cell module begins to output electrical energy, while a portion of the electrical energy is replenished to the lithium battery in the control module.

[0025] like Figures 1-10 As shown, the aluminum-water hydrogen production reactor has an adaptive thermal stress compensation structure, including a reactor 1 and an inner liner 22 located inside the reactor 1. In this embodiment, an open reactor 1 is used to facilitate the placement of aluminum plates for hydrogen production. The inner liner 22 can be integrally cast based on alumina ceramic or reaction-sintered silicon carbide. A filling and bonding layer 21 made of mullite or corundum refractory is also used to fill and bond the space between the reactor 1 and the inner liner 22. During operation, aluminum plates and water are placed into the inner liner 22, which generates heat instantly. The filling and bonding layer 21 is used to tighten the reactor 1 and the inner liner 22 to relieve the thermal stress caused by the temperature difference between them.

[0026] The shape of the reactor 1 is not limited to cylindrical, cuboid, trapezoidal, etc. In this embodiment, a cuboid reactor 1 is preferred, which can lay the aluminum plate flat to prevent the edges and corners of the aluminum plate from hitting the inner liner shell 22, or the aluminum plate can be beveled in advance in the factory for use.

[0027] See attached document Figure 6 , Figure 8 and Figure 9 To enhance the tightness of the connection between the reactor 1 and the inner liner shell 22, this embodiment also provides a first alloy traction member 10 and a second alloy traction member 15 in the filling adhesive layer 21. The first alloy traction member 10 and the second alloy traction member 15 can be exposed at one end. When pouring the filling adhesive layer 21, the exposed part is wrapped with the pouring material, so that the first alloy traction member 10 and the second alloy traction member 15 can pull the inner liner shell 22 at multiple points.

[0028] The first alloy traction component 10 and the second alloy traction component 15 can both be made of top-grade nickel-based alloys such as Hastelloy C-276. Their structural strength will be greater than that of the reactor 1 and the inner liner shell 22. Moreover, their thermal conductivity is greater than that of the reactor 1. When they work together with the filling and bonding layer 21 to resist the deformation caused by thermal stress, they can enhance the efficiency of heat transfer from the inner liner shell 22 to the reactor 1.

[0029] See attached document Figure 1 , Figure 2 and Figure 7To improve the instantaneous heat conduction efficiency between the reactor 1 and the inner liner shell 22, it is necessary to open a heat transfer channel. Therefore, in this embodiment, a first fiber 11, a second fiber 16 and a third fiber 20 connected in a mesh cage are installed on the outside of the reactor 1. The mesh cage based on carbon fiber material can quickly dissipate heat through external water cooling or air cooling, and the mesh nodes of the mesh cage extend into the reactor 1 and connect with the inner liner shell 22. During hydrogen production, the aluminum plate reacts with water to generate heat, causing the local temperature of the inner liner shell 22 to rise instantaneously. The heat from the inner liner shell 22 is conducted to the outside of the reactor 1 along the mesh cage, accelerating the heat transfer between the reactor 1 and the inner liner shell 22. This heat transfer is achieved through the mesh cage, which has a large radiation area and can dissipate heat from the inner liner shell 22 quickly, achieving rapid temperature equilibrium after temperature changes in the reactor 1 and the inner liner shell 22. The thermal stress between the reactor 1 and the inner liner shell 22 is reduced by the mesh nodes, the first alloy traction component 10, and the second alloy traction component 15, thus reducing the possibility of cracking, bulging, and other potential problems. Since the mesh cage pulls the inner liner shell 22 through the mesh nodes, it has a large radiation area and can play a pulling role at the heating point of the aluminum molten reaction, complete the adaptive thermal stress compensation, and resist the possible deformation between the reactor 1 and the inner liner shell 22 caused by the thermal stress change at this location. Moreover, it hardly increases the volume of reactor 1, which makes it easy for the aluminum-water hydrogen production individual soldier power equipment to remain small, easy for individual soldiers to carry in the field, and easy to find water sources to use as needed, and can quickly produce hydrogen for combustion power generation.

[0030] See attached document Figure 7 , Figure 8 and Figure 9 In this embodiment, the first fiber 11 is arranged on both sides of the reactor 1, and the second fiber 16 is arranged on the other two sides of the reactor 1. It can surround the reactor 1, reduce the blank area, and can be connected to the first fiber 11 and the second fiber 16 by means of carbon fiber tape sewing in a ring path. In this way, the tensile strength of the mesh cage is enhanced, and the contact surface with the external heat-conducting medium is larger, which facilitates faster heat dissipation. The mesh nodes of the first fiber 11 penetrate the first alloy traction member 10, so that the first fiber 11 and the first alloy traction member 10 cooperate with each other to pull the inner liner shell 22, resulting in stronger tensile strength. The mesh nodes of the second fiber 16 penetrate the second alloy traction member 15, so that the second fiber 16 and the second alloy traction member 15 cooperate with each other to pull the inner liner shell 22, resulting in stronger tensile strength. The first alloy traction component 10, the first fiber 11, the second alloy traction component 15, and the second fiber 16 are all partially embedded inside the inner liner shell 22, and can contact the inner liner shell 22 to realize the transfer of heat on the inner liner shell 22. Furthermore, at the interval between the reactor 1 and the inner liner shell 22, the traction and filling adhesive layer 21 are tightly connected to resist the deformation of the inner liner shell 22 caused by thermal stress.

[0031] See attached document Figure 6 , Figure 7 and Figure 10 The mesh nodes of the third fiber 20 are embedded in the bottom of the inner liner shell 22 in a forked manner, so that the mesh cage can hold the bottom of the inner liner shell 22. It can not only transfer the heat from the sides of the inner liner shell 22, but also directly transfer the heat from the bottom of the inner liner shell 22. In conjunction with the filling adhesive layer 21, it pulls the bottom of the inner liner shell 22, reducing cracking and bulging caused by thermal stress at the contact surface between the inner liner shell 22 and the aluminum plate. The width of the mesh cage is smaller than the thickness of the filling adhesive layer 21, which provides sufficient casting space for the filling adhesive layer 21, reduces the internal stress of the filling adhesive layer 21, and reduces the occurrence of cracking of the filling adhesive layer 21 when subjected to thermal stress.

[0032] See attached document Figure 3 and Figure 5 The reactor 1 has a removable top cover 23 installed at the opening by bolts. The top cover 23 is connected to a water inlet 24 and a gas outlet 25, which respectively allow water to be input through the water inlet 24 and hydrogen to be output through the gas outlet 25. There is a gap between the inner liner 22 and the top cover 23 to prevent the top cover 23 from squeezing the inner liner 22. A reinforcing rib plate 26 is welded to the outer edge of the opening of the reactor 1 to help maintain the shape of the opening of the reactor 1 and prevent deformation of the opening of the reactor 1 from aggravating the stress on the inner liner shell 22. The height of the reinforcing rib plate 26 is greater than the height of the mesh cage, leaving enough space for the layout of the mesh cage.

[0033] See attached document Figure 4 , Figure 6 and Figure 7 Both sides of the reactor 1 are provided with a first groove 7 and a first through hole 8 located in the first groove 7, so as to facilitate the passage of the first fiber 11; The first groove 7 is used to accommodate the first alloy traction member 10 and the filling adhesive layer 21, which can increase the interlocking surface between the filling adhesive layer 21 and the reactor 1, making the connection tighter. The mesh nodes of the first fiber 11 penetrate the filling adhesive layer 21 along the first through hole 8, which facilitates the straightening of the first fiber 11 and timely tightening of the reactor 1 and the inner liner shell 22.

[0034] See attached document Figure 6 , Figure 7 and Figure 8In this embodiment, a first buckle 9 for suspending the first alloy traction member 10 is welded inside the first groove 7. The first buckle 9 and the first alloy traction member 10 are made of the same material. After the first fiber 11 is installed, the first alloy traction member 10 can hook the first buckle 9 to form part of the alloy skeleton. This can strengthen the tightness of the support between the reactor 1 and the inner liner 22 after the filling adhesive layer 21 and the inner liner 22 are poured. The mesh nodes of the first fiber 11 wrap around the first buckle 9 along the surface of the first alloy traction member 10, and are tightly wound, which facilitates the alloy skeleton and the mesh cage to exert force synchronously.

[0035] See attached document Figure 4 , Figure 6 and Figure 7 The reactor 1 has a second groove 12 on each side and a second through hole 13 inside the second groove 12 to facilitate the passage of the second fiber 16. The second groove 12 is used to accommodate the second alloy traction component 15 and the filling adhesive layer 21, which can increase the contact surface between the filling adhesive layer 21 and the reactor 1, making the connection tighter. The mesh nodes of the second fiber 16 penetrate the filling adhesive layer 21 along the second through hole 13, which facilitates the straightening of the second fiber 16 and timely tightening of the reactor 1 and the inner liner shell 22.

[0036] See attached document Figure 7 and Figure 9 In this embodiment, a second buckle 14 for suspending the second alloy traction member 15 is also fixed inside the second groove 12. The second buckle 14 and the second alloy traction member 15 are made of the same material. After the second fiber 16 is installed, the second alloy traction member 15 can hook the second buckle 14 to form another part of the alloy skeleton. This can strengthen the tightness of the support between the reactor 1 and the inner liner 22 after the filling adhesive layer 21 and the inner liner 22 are poured. The mesh nodes of the second fiber 16 wrap around the second buckle 14 along the surface of the second alloy traction member 15, and are tightly wound, which facilitates the alloy skeleton and the mesh cage to exert force synchronously.

[0037] See attached document Figure 6 , Figure 7 and Figure 10 The bottom wall of the reactor 1 is provided with a third groove 17 and a third through hole 18 located inside the third groove 17, so as to facilitate the passage of the third fiber 20. The third groove 17 is used to accommodate the filling adhesive layer 21 and the third groove 17 is welded with the third alloy traction member 19, so that the third alloy traction member 19, as another part of the alloy skeleton, can strengthen the tightness of the support between the reactor 1 and the inner liner 22 after the filling adhesive layer 21 and the inner liner 22 are cast. The mesh nodes of the third fiber 20 pass through the third through hole 18 and the third alloy traction member 19, so that the third fiber 20 and the third alloy traction member 19 are tightly connected, which facilitates the alloy skeleton and the mesh cage to exert force synchronously.

[0038] See attached document Figure 6 and Figure 10 The third alloy traction component 19 is forked and fits into the fork of the third fiber 20, and the fork of the third alloy traction component 19 is embedded in the filling adhesive layer 21. The fork is triangular, and after being connected to the inner liner shell 22, the connection surface is triangular, which has high stability. The projected area of ​​the third alloy traction member 19 on the bottom wall of the third groove 17 is greater than the cross-sectional area of ​​the third groove 17, so that the traction surface of the third fiber 20 is not limited to the surface where the third groove 17 is located.

[0039] The working principle of this invention is as follows: when aluminum plate and water are placed into inner liner shell 22, heat is generated instantly, causing the local temperature of inner liner shell 22 to rise instantly. The heat of inner liner shell 22 is conducted to the outside of reactor 1 along the mesh cage, which accelerates the heat transfer between reactor 1 and inner liner shell 22. Moreover, this heat transfer is achieved through the mesh cage, which can dissipate heat from inner liner shell 22 more quickly and achieve temperature balance after temperature changes in reactor 1 and inner liner shell 22.

[0040] Furthermore, by using grid nodes, the first alloy traction component 10, and the second alloy traction component 15, the thermal stress between the reactor 1 and the inner liner shell 22 is reduced, thereby reducing the possibility of cracking, bulging, and other hidden dangers. This achieves adaptive thermal stress compensation, resisting the possible deformation between the reactor 1 and the inner liner shell 22 caused by changes in thermal stress at this location. Moreover, it hardly increases the volume of the reactor 1, keeping the aluminum-water hydrogen production individual power supply equipment miniaturized.

[0041] The first alloy traction component 10, the first fiber 11, the second alloy traction component 15, and the second fiber 16 are all partially embedded inside the inner liner shell 22, and can contact the inner liner shell 22 to realize the transfer of heat on the inner liner shell 22. They are also tightly connected to the adhesive layer 21 at the interval between the reactor 1 and the inner liner shell 22. The first alloy traction component 10, the second alloy traction component 15, and the third alloy traction component 19 form an alloy skeleton, so that the alloy skeleton is tightly connected to the mesh cage and exerts force synchronously.

[0042] The above description is merely an optional embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described or explained in this invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
