Description

Technical Field

[0001] This application belongs to the field of hydrogen energy technology, specifically relating to an improved flow channel mounting frame and an air-cooled solid hydrogen storage device. Background Technology

[0002] Hydrogen energy, as a clean and efficient secondary energy source, is a key element in driving energy structure transformation. Solid-state hydrogen storage technology converts hydrogen gas into solid metal hydrides through chemical reactions, offering significant advantages such as low pressure, leak-free operation, and high safety, demonstrating broad application prospects in new energy, transportation, and energy storage. Solid-state hydrogen storage devices, composed of multiple solid hydrogen storage cylinders and an external frame, are suitable for various environments due to their small size and easy cylinder replacement, such as sightseeing vehicles, patrol vehicles, and as energy storage modules for small, portable hydrogen power generation systems. However, in practical applications, this type of solid-state hydrogen storage device faces challenges due to its overly simplistic design, including simple flow channels and insufficient heat transfer. When releasing hydrogen, the storage material needs to absorb external heat; low heat transfer efficiency leads to slow hydrogen release reaction rates and uneven temperature distribution, severely impacting the overall performance and reliability of the device.

[0003] In summary, the existing technologies have the following drawbacks: 1. Solid hydrogen storage devices composed of multiple solid hydrogen storage cylinders are mostly air-cooled, but the heat transfer is insufficient, requiring the addition of heating elements for auxiliary heating; 2. The air-cooled solid hydrogen storage devices composed of hydrogen storage cylinders lack a suitable air guiding structure inside. After the waste heat from the fuel cell stack enters through the air inlet, it is only blown onto a portion of the hydrogen storage cylinders, failing to ensure uniform heating; 3. The air inlets of air-cooled solid hydrogen storage devices composed of hydrogen storage cylinders are mostly grid plates, which do not effectively guide the waste heat from the fuel cell stack; 4. The left and right sides of air-cooled solid hydrogen storage devices composed of hydrogen storage cylinders are mostly enclosed to ensure the airtightness of the space, which creates dead zones for fluid flow and results in poor fluidity. Utility Model Content

[0004] The purpose of this application is to provide an improved flow channel mounting frame and an air-cooled solid hydrogen storage device, which solves the problems of insufficient heat transfer and uneven heating in existing solid hydrogen storage devices.

[0005] The objective of this application is achieved through the following technical solution: An improved flow channel mounting frame includes a frame body, an inlet dispersing flow channel at the front end of the frame body, an outlet converging flow channel at the rear end of the frame body, and an internal guide plate assembly and a bottle mounting position located between the inlet dispersing flow channel and the outlet converging flow channel within the frame body. The internal guide plate assembly includes a number of guide plates arranged at intervals, and the guide plates gradually tilt towards the bottle mounting position from the outside to the inside in the direction from the inlet to the outlet.

[0006] Furthermore, the frame body includes an inlet frame, an outlet frame, side frames, and a base. The inlet dispersing flow channel is located on the inlet frame, the outlet converging flow channel is located on the outlet frame, the two side frames are respectively connected between the two sides of the inlet frame and the outlet frame, and the base is connected between the bottom of the inlet frame, the outlet frame, and the side frames. The base is provided with a bottle placement groove.

[0007] Furthermore, the frame body also includes an inner cover plate and a top cover. The inner cover plate is detachably connected between the upper parts of the inlet frame, the outlet frame, and the side frame. The inner cover plate is provided with a bottle placement hole. The inlet frame or the outlet frame is hinged to the top cover.

[0008] Furthermore, both the inlet dispersion channel and the outlet convergence channel include an upper inlet / outlet plate, a lower inlet / outlet plate, and inlet / outlet blades. The upper inlet / outlet plate and the lower inlet / outlet plate are mounted on the frame body. Several inlet / outlet blades are vertically fixed between the upper inlet / outlet plate and the lower inlet / outlet plate. The inlet / outlet blades of the inlet dispersion channel gradually tilt from the center to both sides along the outer side to the inner side, and the inlet / outlet blades of the outlet convergence channel gradually tilt from both sides to the center along the inner side to the outer side.

[0009] Furthermore, the frame body is provided with openable and closable side guide channels on both sides.

[0010] Furthermore, the side guide channel includes an upper side plate, a lower side plate, side blades, and a control plate. The upper side plate and the lower side plate are mounted on the frame body. Several side blades are vertically hinged between the upper side plate and the lower side plate, and several side blades are all hinged to the control plate.

[0011] Furthermore, the length of the aforementioned guide vanes gradually increases along the inlet to outlet direction.

[0012] Furthermore, the internal guide plate assembly also includes an upper guide plate, with each guide plate fixed to the upper guide plate, which is provided with a bottle matching groove.

[0013] Furthermore, the internal guide plate assembly is arranged on both sides of the bottle placement position.

[0014] An air-cooled solid hydrogen storage device with improved flow channel includes an air-cooled solid hydrogen storage cylinder and a mounting frame with improved flow channel, wherein the air-cooled solid hydrogen storage cylinder is located in a cylinder mounting position on the frame body.

[0015] The beneficial effects of this application are: 1. Solve the heat exchange problem: Add multiple flow channels to improve the structure, make full use of the waste heat of the fuel cell stack, and allow the hydrogen storage tank inside the device to have full contact with the fluid.

[0016] 2. Solve the problem of internal air guiding structure: Add guide plate structures at different angles on the left and right sides inside the device to guide the air from the hot air inlet of the device to all parts of the hydrogen storage tank, ensuring uniform and good heat exchange, and at the same time guiding external gas into the device.

[0017] 3. Hot air inlet issue: Add vertical louver blades at different angles to the air inlet of the unit to ensure that the hot air from the fuel cell stack can flow in all directions within the unit as much as possible.

[0018] 4. Sealing the left and right sides of the external frame of the device will cause dead zones for fluid flow inside the device. Adding vertical adjustable louvers to the left and right sides of the external frame can guide more hot air from the outside into the device when the external ambient temperature is high, thereby increasing heat exchange.

Detailed Implementation

[0029] The present application will be further described below with reference to specific embodiments and accompanying drawings.

[0030] Example 1 refer to Figures 1-8 As shown, an improved flow channel mounting frame includes a frame body 100, an inlet dispersing flow channel 200, an outlet converging flow channel 300, a side guide flow channel 400, and an internal guide plate assembly 500. The frame body 100 is used to accommodate and mount the air-cooled solid hydrogen storage cylinder 600, and also to achieve its own installation and fixation. At the same time, the frame body 100 also provides a foundation for the installation of other components, and also forms a space for heat exchange inside.

[0031] The front end of the frame body 100 is provided with an inlet dispersion channel 200, which is used to divert and diffuse the incoming air. That is, louver blades of different angles are added to the air inlet of the frame to ensure that the hot air from the fuel cell stack can flow in all directions within the frame as much as possible.

[0032] The rear end of the frame body 100 is provided with an outlet converging channel 300, which is used to collect and gather the air. That is, louver blades of different angles are added to the air outlet of the frame to ensure that air in all directions inside the frame can be smoothly discharged, avoiding dead corners that affect heat exchange efficiency.

[0033] The frame body 100 contains an internal guide plate assembly 500 and a bottle placement position located between the inlet dispersing channel 200 and the outlet converging channel 300. The internal guide plate assembly 500 guides and disperses the airflow entering the frame to ensure sufficient and uniform heat exchange between the airflow and the bottle. Specifically, guide plates at different angles are added to the left and right sides inside the frame to direct the incoming hot air to all parts of the hydrogen storage cylinder, ensuring uniform and good heat exchange. Simultaneously, it accelerates airflow on the left and right sides, changing the pressure difference inside and outside the device and guiding external gas in. The bottle placement position is used to secure the hydrogen storage cylinder.

[0034] The frame body 100 has openable and closable side guide channels 400 on both sides, which enable communication between the inside and outside of the two sides and improve the overall air intake capacity in special circumstances. That is, vertical adjustable louvers are added to the left and right sides of the frame. When the external ambient temperature is high, more external hot air can be guided into the device to increase heat exchange. At the same time, this structure can be closed when the external ambient temperature is low.

[0035] The frame body 100 is a rectangular box-type frame welded from steel pipes and steel plates, including an inlet frame 101, an outlet frame 102, side frames 103, a base 104, an inner cover plate 106, and a top cover 108. The inlet dispersing flow channel 200 is located on the inlet frame 101, the outlet converging flow channel 300 is located on the outlet frame 102, the side guiding flow channel 400 is located on the side frame 103, and the internal guide plate assembly 500 is located on the base 104.

[0036] Two side frames 103 are welded to the sides of the inlet frame 101 and the outlet frame 102, respectively. The base 104 is welded to the bottom of the inlet frame 101, the outlet frame 102, and the side frames 103. Thus, the inlet frame 101, the outlet frame 102, the side frames 103, and the base 104 together form a rectangular box-shaped frame with an upper opening, allowing for the maintenance or replacement of the hydrogen storage cylinder. The inlet frame 101 or the outlet frame 102 is hinged to the top cover 108 via a hinge 109, which closes the upper opening to create a relatively enclosed internal space.

[0037] The base 104 has a bottle placement groove 105 for placing the bottom of the hydrogen storage bottle. An inner cover plate 106 is detachably connected between the upper parts of the inlet frame 101, outlet frame 102, and side frame 103. The inner cover plate 106 has a bottle placement hole 107, through which the upper part of the hydrogen storage bottle can pass to limit and fix the bottle. The bottle placement groove 105 and the bottle placement hole 107 together form a bottle placement position; preferably, two bottle placement positions are arranged on the left and right sides within the frame. The bottle placement hole 107 on the inner cover plate 106 is smaller than the diameter of the solid hydrogen storage bottle, and together with the bottle placement groove 105 on the base 104, it fixes the solid hydrogen storage bottle in place. The inner cover plate 106 is fixed to the frame in four directions using L-shaped connectors 110 and screws to prevent vertical movement. Meanwhile, the inner cover plate 106 shields the upper part of the hydrogen storage cylinder to ensure that the hot air enters the frame and makes full contact with the cylinder body for heat exchange, minimizing the flow of hot air in areas where heat is not needed, such as the cylinder opening and valves, so as to ensure the heat exchange effect of the cylinder body.

[0038] Both the inlet dispersing channel 200 and the outlet converging channel 300 include an upper inlet / outlet plate 201, a lower inlet / outlet plate 202, and inlet / outlet blades 203. The upper inlet / outlet plate 201 and the lower inlet / outlet plate 202 have pre-drilled screw holes to secure the plates to the frame body 100 using bolts. Several inlet / outlet blades 203 are vertically welded and fixed between the upper inlet / outlet plate 201 and the lower inlet / outlet plate 202. All inlet / outlet blades 203 are rectangular plates of equal size. During installation, the upper and lower plates are first positioned and installed, and finally the blades and the upper and lower plates are fixed by welding or other methods.

[0039] The inlet and outlet blades 203 of the inlet dispersion channel 200 gradually tilt from the outside to the inside and from the center to both sides, realizing the diversion and diffusion from the outside to the inside. The inlet and outlet blades 203 of the outlet convergence channel 300 gradually tilt from the inside to the outside and from both sides to the center, realizing the aggregation and collection from the inside to the outside.

[0040] The side guide channel 400 includes an upper side plate 401, a lower side plate 402, side blades 403, and a control plate 404. The upper side plate 401 and the lower side plate 402 have pre-drilled screw holes to secure the plates to the frame body 100 using bolts. Several side blades 403 are vertically hinged between the upper side plate 401 and the lower side plate 402 via end shafts at their upper and lower centers, allowing the side blades 403 to rotate and adjust their angle.

[0041] The side blades 403 are all rectangular plates of equal size. The rotation of the side blades 403 changes the guide angle or directly opens and closes the flow channel. Several side blades 403 are hinged to a control plate 404. Specifically, the control plate 404 has pre-drilled protrusions, and the side blades 403 have pre-drilled circular holes. The hinge is formed by the cooperation of the protrusions and the circular holes. The control plate 404 is a long strip structure, used to uniformly control all the side blades 403 for convenient operation.

[0042] During installation, first, the upper and lower plates are hinged together with the blades. Then, the assembled components are placed on the side of the frame and the upper and lower plates are fixed with bolts. Finally, the control plate is inserted into the pre-drilled hole in the blade.

[0043] The internal guide vane assembly 500 includes guide vanes 501 and an upper guide plate 502. Several guide vanes 501 are arranged at intervals to create a continuous and sufficient guiding effect. The guide vanes 501 gradually tilt inwards towards the cylinder placement position from the outside to the outlet direction. At the inlet position, the angle between the guide vanes 501 and the flow direction is small, and the guiding effect of the guide vanes 501 on the airflow is weak, only converging the airflow towards the center. At this point, the incoming air can also be directly blown onto the front surface of the hydrogen storage cylinder. As the airflow continues to flow inwards, it cannot fully contact the side surface of the hydrogen storage cylinder. The tilt angle of the guide vanes 501 gradually increases, and the guiding effect on the airflow gradually strengthens, allowing the airflow to be blown as far as possible to the side of the hydrogen storage cylinder. When the airflow reaches the outlet position, it can no longer directly contact the rear surface of the hydrogen storage cylinder. The guide vanes 501 then face completely towards the cylinder placement position, acting as a horizontal block for the airflow, allowing the airflow to finally turn at a large angle and be blown onto the rear surface of the hydrogen storage cylinder, achieving uniform heat exchange.

[0044] The guide plate 501 is a rectangular plate with increased size (length). Several guide plates 501 gradually increase in length along the direction from the inlet to the outlet. That is, as the tilt angle of the guide plate 501 increases, the guiding area of ​​the guide plate 501 also increases, which further enhances the guiding effect on the airflow, accelerates the airflow on the left and right sides, changes the pressure difference inside and outside the device, and guides the external gas to enter.

[0045] Internal guide vane assemblies 500 are arranged on both sides of the bottle placement position, forming a symmetrical flow channel structure to ensure effective heat exchange on both sides. Each set of guide vanes 501 is welded and fixed to the same upper guide plate 502, which reinforces the guide vanes 501 to maintain their orientation. The upper guide plate 502 is provided with a bottle matching groove 503 to match the bottle body structure of the hydrogen storage bottle, further increasing the stability of the hydrogen storage bottle placement. During installation, the guide vanes are first fixed to the base 104 by welding or other methods, and then the upper plate is fixed to the guide vanes in the same way.

[0046] Example 2 refer to Figures 1-8 As shown, an air-cooled solid hydrogen storage device with improved flow channels includes an air-cooled solid hydrogen storage cylinder 600 and a flow channel improved mounting frame as described in Example 1.

[0047] The air-cooled solid hydrogen storage cylinder 600 is located in the cylinder placement position on the frame body 100. Specifically, the bottom of the hydrogen storage cylinder is placed in the cylinder placement groove 105 of the base 104, and the upper part of the hydrogen storage cylinder is limited by the cylinder placement hole 107 of the inner cover plate 106 to ensure the stable placement of the hydrogen storage cylinder inside the frame. If there are two cylinder placement positions on the left and right sides inside the frame, two hydrogen storage cylinders can be placed accordingly.

In the scheme of this application, each alternative example can be arbitrarily combined with any other basic example and alternative example.
