Description

TECHNICAL FIELD

[0001] The utility model belongs to solid hydrogen storage technical field, especially relates to a self -heating solid hydrogen storage device. BACKGROUND

[0002] Hydrogen energy is a new type of energy with clean, low carbon, renewable and other characteristics. The current hydrogen storage mode is divided into: high pressure gaseous hydrogen storage, cryogenic liquid hydrogen storage and solid hydrogen storage with hydrogen storage material as medium. Because solid hydrogen storage has the advantages of high volume hydrogen storage density, low pressure safety and high hydrogen purity, solid hydrogen storage is an important direction for the future development of hydrogen storage technology.

[0003] Solid hydrogen storage material releases heat when storing hydrogen, and needs to absorb heat from the outside when releasing hydrogen. The existing solid hydrogen storage technology mostly uses water bath heating method, which has a narrow temperature range and a large volume expansion coefficient, and the hydrogen storage bottle is directly in contact with water, which causes corrosion. To solve the above problems, a solid hydrogen storage device with authorization publication No. CN221504700U is disclosed, which includes a heat exchange water tank, a heat conducting component, a hydrogen storage bottle single body, a gas conveying component and a liquid circulating component. The heat exchange water tank is provided with a liquid inlet, a liquid outlet and a plurality of hydrogen storage bottle placing cavities, and the hydrogen storage bottle placing cavities are filled with heat exchange liquid outside. The heat conducting component is arranged inside the hydrogen storage bottle placing cavity, and the hydrogen storage bottle single body is placed inside the heat conducting component, which has a bottle mouth extending out of the hydrogen storage bottle placing cavity, and the gas conveying component is connected with the bottle mouth. The two ends of the liquid circulating component are connected with the liquid inlet and the liquid outlet through the liquid conveying pipe respectively, which is used for circulating the heat exchange liquid for the heat exchange water tank. The inner and outer sides of the heat conducting component are in close contact with the outer wall of the hydrogen storage bottle single body and the inner wall of the hydrogen storage bottle placing cavity respectively.

[0004] In the above patent, the hydrogen storage bottle single body exchanges heat with the heat exchange liquid through the heat conducting component and the hydrogen storage bottle placing cavity, which is equivalent to isolating the hydrogen storage bottle single body from the heat exchange liquid, thereby avoiding the problem of corrosion of the hydrogen storage bottle single body by the heat exchange liquid. However, since the heat exchange water tank needs an external liquid circulating component to provide heat exchange liquid for the heat exchange water tank, it is necessary to connect liquid conveying pump, liquid conveying pipe and other components on the heat exchange water tank. Especially in the case of frequent change of liquid temperature, additional equipment is needed to heat or cool the heat exchange liquid, which has a complex structure. UTILITY MODEL CONTENTS

Multiple hydrogen storage cylinder fixing sleeves are installed in the heat exchange chamber to secure the hydrogen storage cylinders. The fixing sleeves separate the hydrogen storage cylinders from the heat exchange liquid and facilitate heat exchange with the liquid. The housing integrates a self-heating control system, which includes a heating device and a temperature sensor located within the heat exchange chamber, and a temperature controller located outside the heat exchange chamber. The heating device heats the heat exchange liquid, the temperature sensor detects the temperature of the heat exchange liquid, and the temperature controller is communicatively connected to the temperature sensor and controllably connected to the heating device.

[0008] The beneficial effects of this utility model are as follows: The self-heating solid hydrogen storage device of this utility model separates the hydrogen storage bottle fixing cylinder from the heat exchange liquid, avoiding corrosion of the hydrogen storage bottle by the heat exchange liquid. On this basis, a heating device is set in the heat exchange chamber to heat the heat exchange liquid. The temperature of the heat exchange liquid is monitored in real time by a temperature sensor, and the heating temperature and the opening and closing of the heating device are set by a temperature controller. The self-heating control system can eliminate the need for external liquid delivery pipelines, delivery pumps and other equipment.

At the same time, it can achieve precise temperature control, reduce energy loss, and improve the convenience of using the solid hydrogen storage device.

[0009] Furthermore, the box body is also provided with a heat dissipation chamber that is separated from the heat exchange chamber. The heat dissipation chamber is connected to one end of the hydrogen storage cylinder fixing cylinder, and a cooling structure is provided on the box body at the position corresponding to the heat dissipation chamber.

[0010] Beneficial effects: It can cool solid hydrogen storage materials while storing hydrogen, and the cooling structure is integrated into the housing, eliminating the need for external cooling devices.

[0013] Furthermore, the enclosure also includes an operating chamber separated from the heat dissipation chamber. The operating chamber contains a gas pipeline assembly for detachable connection with each hydrogen storage cylinder, as well as a hydrogen concentration alarm. A cover that can be opened and closed is provided on the enclosure corresponding to the position of the operating chamber.

[0014] Beneficial effects: The gas pipeline components, self-heating control system, and air-cooling structure are all integrated into one housing, resulting in a highly compact overall structure with efficient heat exchange capabilities. This simplifies the system architecture, reduces manufacturing costs, and facilitates large-scale manufacturing and transportation.

[0015] Furthermore, a hydrogen filling port, a hydrogen filling shut-off valve, a hydrogen discharging port, a hydrogen discharging shut-off valve, and a pressure gauge are installed on the side wall of the box corresponding to the operating chamber.

[0017] Furthermore, the chamber is provided with a first partition and a second partition arranged in parallel and at intervals. The first partition and the second partition divide the space inside the chamber into the heat exchange chamber, the heat dissipation chamber and the operating chamber. The neck of the hydrogen storage cylinder protrudes from the first partition and passes through the second partition. The first partition and the second partition are detachably connected by a fastening assembly so that the second partition presses against the hydrogen storage cylinder.

[0018] Beneficial effect: After the solid hydrogen storage material reaches the end of its service life, the second partition can be removed and the hydrogen storage bottle can be taken out for replacement.

[0019] Furthermore, the hydrogen storage cylinder fixing sleeve includes a thermally conductive inner sleeve and a thermally conductive material for filling between the hydrogen storage cylinder and the thermally conductive inner sleeve. The top end of the thermally conductive inner sleeve is sealed to the first partition plate, and the bottom end of the thermally conductive inner sleeve is provided with multiple flow gaps communicating with the heat exchange chamber. The flow gaps allow the heat exchange liquid to flow so that the heat exchange liquid exchanges heat with the bottom of the hydrogen storage cylinder.

[0020] Beneficial effects: It can effectively improve the heating efficiency of the heat exchange liquid on solid hydrogen storage materials.

[0021] Furthermore, the heat exchange fluid is heat transfer oil.

[0022] Beneficial effects: When using heat transfer oil, it has less corrosiveness to metals, and the heat transfer oil has a wider heat transfer temperature range, which can better ensure stable, continuous and efficient hydrogen release.

[0023] Furthermore, the hydrogen storage cylinder fixing cylinder is provided with multiple layers along its vertical direction, and each layer includes multiple horizontally spaced hydrogen storage cylinder fixing cylinders.

[0024] Beneficial effects: It can hold multiple hydrogen storage cylinders at once, which can meet the hydrogen demand in different scenarios.

Detailed Implementation

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0038] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0039] Example 1 of the self-heating solid hydrogen storage device provided by this utility model:

[0040] like Figure 1 and Figure 2 As shown, the self-heating solid hydrogen storage device includes a housing 6 and a self-heating control system integrated on the housing 6, a hydrogen storage cylinder fixing cylinder 36, a hydrogen storage cylinder 22, a gas pipeline assembly, and an air-cooling structure.

[0041] Specifically, such as Figure 2 As shown, the box 6 has a cuboid structure. The box 6 is provided with a first partition 20 and a second partition 21 arranged in parallel and at intervals. The first partition 20 and the second partition 21 divide the space inside the box 6 into a heat exchange chamber 35, a heat dissipation chamber 40 and an operation chamber 37. The first partition 20 is welded and sealed to the box 6.

[0042] The heat exchange chamber 35 is used to store the heat exchange fluid. In this embodiment, the heat exchange fluid is heat transfer oil. Of course, water can also be used. The side wall of the housing 6 is provided with a liquid inlet 19, an exhaust port 7, and a drain port 5 at the positions corresponding to the heat exchange chamber 35. Each of these interfaces is equipped with a control valve to facilitate the addition and discharge of heat transfer oil.

[0043] The self-heating control system controls the heating temperature of the heat transfer oil and includes a heating device, a temperature sensor 8, and a temperature controller 12. The heating device uses a common heating rod 10, which is inserted into the heat exchange chamber 35 and sealed to the side wall of the housing 6. When energized, it heats the heat transfer oil within the heat exchange chamber 35. In other embodiments, the heating device can also be a disc-shaped heating tube. The temperature sensor 8 uses a common thermocouple, also inserted into the heat exchange chamber 35, with the insertion point sealed to the housing 6. The temperature sensor 8 is used to measure the temperature of the heat transfer oil in real time. The temperature controller 12 is installed in the operating chamber 37 and fixed to the top surface of the housing 6. The temperature controller 12 is communicatively connected to the temperature sensor 8 and controlled by the heating rod 10. The temperature controller 12 sets the required heating temperature for the heat transfer oil and controls the automatic start and stop of the heating rod 10, ensuring the heat transfer oil temperature remains stable within the set temperature range, guaranteeing the stability of the hydrogen release rate of the hydrogen storage device, and improving hydrogen utilization efficiency. At this point, the entire self-heating solid hydrogen storage device does not require an external heating device, which simplifies the structure, improves the ease of use of the hydrogen storage device, and expands its application areas.

[0044] In this embodiment, as Figure 1 and Figure 3 As shown, the hydrogen storage cylinder fixing cylinder 36 has two layers, with three cylinders arranged horizontally at intervals in each layer. Figure 5 and Figure 6 As shown, each hydrogen storage cylinder fixing sleeve 36 includes a thermally conductive inner sleeve 17 and a thermally conductive material 34. The outer surface of the hydrogen storage cylinder is filled with the thermally conductive material 34 and placed inside the thermally conductive inner sleeve 17. The thermally conductive material 34 is one of aluminum foil, thermally conductive adhesive, and flexible carbon. The bottom of the thermally conductive inner sleeve 17 is provided with a bottom cover 17-1, which is welded and sealed to the circumference of the thermally conductive inner sleeve 17. The bottom end of the thermally conductive inner sleeve 17 is located outside the bottom cover 17-1 and is welded and fixed to the rear wall of the housing 6; the top end of the thermally conductive inner sleeve 17 is welded and sealed to the first partition 20. The bottom end of the thermally conductive inner sleeve 17 is provided with multiple flow gaps 17-2 communicating with the heat exchange chamber 35. The flow gaps 17-2 allow the thermally conductive oil to flow so that the thermally conductive oil can exchange heat with the bottom of the hydrogen storage cylinder 22.

[0045] like Figure 2 As shown, the neck of the hydrogen storage cylinder 22 exposes the first partition 20 and passes through the second partition 21. The first partition 20 and the second partition 21 are detachably connected by a fastening assembly 23 so that the second partition 21 presses against the hydrogen storage cylinder 22. Specifically, as...Figure 5 As shown, the opening of the hydrogen storage cylinder 22 is provided with a limiting plane 22-1, as follows: Figure 8 As shown, the second partition 21 has bolt holes 21-1 and hydrogen storage bottle fixing holes 21-2 corresponding to the number of hydrogen storage bottles 22. The hydrogen storage bottle fixing holes 21-2 have limiting notches 21-3, which cooperate with the limiting plane 22-1 of the hydrogen storage bottles 22. The fastening assembly 23 includes fastening bolts and fastening nuts. The fastening bolts are spot-welded to the first partition 20 and pass through the second partition 21. The neck of the hydrogen storage bottle 22 protrudes from the first partition 20 and passes through the second partition 21. By tightening the fastening nut on the side of the second partition 21 opposite to the first partition 20, the second partition 21 is pressed together, thereby fixing the hydrogen storage bottle 22. After the solid hydrogen storage material reaches the end of its service life, the fastening nut can be loosened, the second partition 21 removed, and the hydrogen storage bottle 22 taken out for replacement. Figure 3 As shown, the second partition 21 is also provided with hydrogen storage bottle identification 25 for each hydrogen storage bottle 22.

[0046] Once the heat exchange chamber 35 is filled with heat transfer oil, the inner heat transfer sleeve 17 is immersed in the oil. The hydrogen release process of the self-heating solid hydrogen storage device is an endothermic phase. During the heating of the heat transfer oil by the heating rod 10, heat is transferred to the hydrogen storage cylinder 22 and the solid hydrogen storage material through the inner heat transfer sleeve 17 and the heat transfer material 34, ensuring stable operation of the hydrogen release process. The inner heat transfer sleeve 17 and the first partition 20 separate the heat transfer oil from the hydrogen storage cylinder 22, effectively isolating hydrogen from the heat transfer oil and ensuring the safe operation of the device.

[0047] Because the heat transfer oil expands easily when heated, a reinforcing rib plate 18 is connected inside the heat exchange chamber 35 to prevent deformation of the housing 6. Figure 2 As shown, the reinforcing ribs 18 are welded to the perimeter of the inner surface of the housing 6 to improve the rigidity of the housing 6. Figure 8 As shown, the top of the reinforcing rib 18 has multiple vents 18-1 spaced apart, the reinforcing rib 18 has multiple passages for the hydrogen storage cylinder fixing cylinder 36 to pass through, and the bottom of the reinforcing rib 18 has multiple liquid passages 18-2 spaced apart. The housing 6 has an exhaust port 7 communicating with the heat exchange chamber 35, and a valve is connected to the exhaust port 7. When adding heat transfer oil, the air in the heat exchange chamber 35 can be discharged through the vents 18-1 and the exhaust port 7.

[0048] like Figure 1 and Figure 4As shown, air-cooling structures are provided on both side walls of the housing 6 corresponding to the heat dissipation chamber 40. These structures include cooling fans 38 mounted on the side walls of the housing 6 and multiple ventilation holes 9 communicating with the heat dissipation chamber 40. After the thermally conductive inner sleeve 17 is fixed, its front end communicates with the heat dissipation chamber 40. When the hydrogen storage device is being filled with hydrogen, turning on the cooling fans 38 allows air circulation to remove the heat released from the hydrogen storage cylinder 22, thereby cooling the solid hydrogen storage material and increasing the hydrogen storage capacity. In this case, no external cooling device is required.

[0049] like Figure 1 and Figure 3 As shown, the operating chamber 37 is equipped with a gas pipeline assembly, and the housing 6 has a hydrogen discharge port 2 and a hydrogen filling port 1 corresponding to the operating chamber 37. The gas pipeline assembly includes a cylinder valve 24, a hydrogen filling pipeline 33, a hydrogen discharge pipeline 28, a hydrogen storage cylinder branch line 29, a four-way connector 27, a three-way shut-off valve 32, a hydrogen filling shut-off valve 4, a hydrogen discharge shut-off valve 3, a one-way valve 31, and a manifold 30. Among them, the cylinder valve 24 corresponds one-to-one with each hydrogen storage cylinder 22, and the cylinder valve 24 is installed at the cylinder opening of the hydrogen storage cylinder 22 to control the filling and use of gas in each hydrogen storage cylinder 22.

[0050] During hydrogen filling, hydrogen filling port 1 is connected to hydrogen filling pipeline 33 and each hydrogen storage cylinder 22 through hydrogen filling stop valve 4 and three-way stop valve 32. Each hydrogen storage cylinder 22 is connected to the manifold pipeline 30 through cylinder valve 24, hydrogen storage cylinder branch line 29, and four-way connector 27. During hydrogen release, three-way stop valve 32 is connected to pressure gauge 11 to measure the gas supply pressure of the pipeline. At the same time, hydrogen release port 2, hydrogen release stop valve 3, and one-way valve 31 are connected to hydrogen release pipeline 28 in sequence, and then connected to each cylinder valve 24 through four-way connector 27, manifold pipeline 30, and hydrogen storage cylinder branch line 29. Hydrogen release port 2 supplies gas to the outside.

[0051] like Figure 1 As shown, a hinged cover 15 is installed on the housing 6 at the position corresponding to the operating chamber 37 via a hinge 26. The cover 15 is equipped with a lock 16. Under normal operation of the solid hydrogen storage device, the cover 15 is closed, effectively protecting the pipelines, valves, and instruments in the operating chamber 37 from external impact damage. The hydrogen charging port 1, hydrogen charging shut-off valve 4, hydrogen discharging port 2, hydrogen discharging shut-off valve 3, pressure gauge 11, and drain port 5 are all integrated on the same side of the housing 6. The temperature controller 12 is fixed on the top surface of the housing 6, and the operation and display panel is exposed outside the housing 6 for easy operation and observation. Of course, depending on the size of the housing 6, the temperature controller 12 can also be integrated into the operation panel for easy operation and observation.

[0052] like Figure 1 As shown, a hydrogen concentration alarm 13 is also provided on the top surface of the housing 6 at the position corresponding to the operating chamber 37, which is used to detect the amount of hydrogen leakage at gas pipelines, valves, and joints, and to ensure the safety of the self-heating solid hydrogen storage device.

[0053] like Figure 1 As shown, a vent 14 is also provided on the top side of the housing 6 to prevent gas accumulation in case of hydrogen leakage. A handle 39 is provided on the side of the housing 6 for moving the hydrogen storage device.

[0054] This application uses heat transfer oil as the heat exchange fluid and employs an independent heat exchange chamber 35 to isolate the heat transfer oil from the hydrogen storage cylinder 22, effectively isolating hydrogen from the heat transfer oil and improving the safety of the hydrogen storage device. Furthermore, the self-heating control system is integrated into the housing 6, eliminating the need for additional components such as infusion pumps and pipelines, thus simplifying the device structure. Moreover, this application also integrates the gas pipeline components and corresponding instruments within the housing 6, making the entire self-heating solid-state hydrogen storage device a single unit, enabling large-scale mass production.

[0055] Example 2 of the self-heating solid hydrogen storage device provided by this utility model:

[0056] Its main difference from Example 1 is:

[0057] In Example 1, the cooling structure adopts an air-cooled structure.

[0058] In this embodiment, a liquid cooling structure is used. A coolant inlet and outlet are located on the side wall of the housing, corresponding to the heat dissipation chamber. During hydrogen filling, coolant is injected into the heat dissipation chamber to cool the hydrogen storage tank. When releasing hydrogen or replacing the hydrogen storage tank, the coolant is released.

[0059] Example 3 of the self-heating solid hydrogen storage device provided by this utility model:

[0060] Its main difference from Example 1 is:

[0061] In Example 1, the cooling structure is integrated into the housing.

[0062] In this embodiment, the hydrogen storage cylinder is cooled by external cooling. In this case, the entire self-heating solid hydrogen storage device does not have a cooling structure, and there is no need to install a second partition.

[0063] Similarly, gas piping components can also be located outside the enclosure and not integrated inside the enclosure.

[0064] In the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.

[0065] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
