Description

Technical Field

[0001] This utility model relates to the field of solid hydrogen storage bottle technology, specifically to a solid hydrogen storage bottle with bifurcated ribs. Background Technology

[0002] Solid hydrogen storage cylinders are hydrogen storage devices that use hydrogen storage materials as the storage medium. They utilize the reversible hydrogen absorption and release capabilities of the hydrogen storage materials. When not generating electricity, the hydrogen storage materials absorb hydrogen to form solid hydrogen and store it. When hydrogen is needed, the solid hydrogen is decomposed under certain conditions (such as heating) to release hydrogen.

[0003] In existing technologies, traditional solid-state hydrogen storage cylinders need to absorb or release heat when absorbing and releasing hydrogen. This is typically achieved by using multiple straight fins inside the cylinder for heat transfer. However, straight fins have poor heat transfer efficiency, resulting in a slow hydrogen absorption and release rate. Therefore, branched fins are often used instead of straight fins for heat transfer. However, existing solid-state hydrogen storage cylinders with branched fins exhibit uneven heat transfer during use. The heat transfer is faster in more sealed areas and slower in more porous areas, leading to uneven heat transfer to the hydrogen storage material and affecting its performance.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example

[0022] Please see Figures 1 to 4 This embodiment proposes a solid hydrogen storage bottle with bifurcated ribs, including a hydrogen storage bottle 1, a bottle head assembly 2 on the hydrogen storage bottle 1, and also includes a central support 3, bifurcated ribs 4, auxiliary ribs 5, hydrogen storage material 6, a heat-conducting layer 7, arc-shaped ribs 8 and a heat-conducting rod 9.

[0023] In this embodiment, by setting multiple auxiliary ribs 5 inside the bifurcated rib 4, the bifurcated rib 4 can conduct heat evenly, reducing the probability of uneven heat transfer from the bifurcated rib 4 to the hydrogen storage material 6, thus ensuring the performance of the hydrogen storage material 6. By opening multiple heat-conducting grooves 10 on the outer surface of the bifurcated rib 4, the disturbance effect on the hydrogen flow is enhanced, thus enhancing the heat transfer effect of the bifurcated rib 4.

[0024] In this embodiment, the uniform conduction of heat inside the hydrogen storage bottle 1 is achieved through the cooperation between the heat-conducting layer 7, the arc-shaped ribs 8 and the heat-conducting rods 9, ensuring the heat conduction effect inside the hydrogen storage bottle 1, thereby ensuring the uniform distribution of heat on the hydrogen storage material 6 and ensuring the performance of the hydrogen storage material 6.

[0025] like Figures 2 to 4 As shown, a central support 3 is installed in the middle of the inner wall of the hydrogen storage cylinder 1. Multiple bifurcated fins 4 are installed on the outer side of the central support 3. Multiple heat-conducting grooves 10 are formed on the outer surface of the bifurcated fins 4. These grooves enhance the disturbance effect of the bifurcated fins 4 on the hydrogen flow, thereby enhancing the heat transfer effect of the bifurcated fins 4. The multiple bifurcated fins 4 are arranged in a ring shape. Multiple auxiliary fins 5 are arranged inside the bifurcated fins 4. These auxiliary fins 5 are inclined downwards inside the bifurcated fins 4. Adjacent auxiliary fins 5 are arranged in an alternating pattern inside the bifurcated fins 4. The alternating inclined auxiliary fins 5 prolong the flow time of the hydrogen fluid inside the bifurcated fins 4, thereby extending the heat transfer between the hydrogen fluid and the hydrogen flow. The contact time is increased, which enhances the heat conduction effect of the bifurcated fins 4. A flow guide seat is provided in the middle of the inner bottom wall of the bifurcated fins 4. The flow guide seat can guide the hydrogen fluid entering the bifurcated fins 4 to the direction of the multiple auxiliary fins 5, thereby ensuring the effectiveness of the auxiliary fins 5 inside the bifurcated fins 4. The hydrogen storage material 6 is placed between the central support 3 and the multiple bifurcated fins 4. The heat conduction layer 7 is placed on the inner wall of the hydrogen storage bottle 1. The heat conduction layer 7 covers the inner side of the inner liner of the hydrogen storage bottle 1 and is used for heat conduction. The heat conduction layer 7 can conduct the heat inside the hydrogen storage bottle 1, so that the heat can be evenly conducted to the hydrogen storage material 6. Multiple arc-shaped fins 8 are installed between the multiple bifurcated fins 4. A heat conduction rod 9 is installed on the outer side of the arc-shaped fin 8 and is connected to the heat conduction layer 7.

[0026] Working principle:

[0027] When it is necessary to convert solid hydrogen crystals into hydrogen gas for release, the operator powers on the hydrogen storage cylinder 1, causing the heating component inside the cylinder 1 to heat the interior. The heat is transferred through the heat-conducting layer 7 to the bifurcated ribs 4, and then from the bifurcated ribs 4 to the hydrogen storage material 6. The heat heats the solid hydrogen crystals on the hydrogen storage material 6, causing them to transform into hydrogen gas and flow upwards. As the hydrogen gas passes through the bifurcated ribs 4, it comes into contact with the auxiliary ribs 5 and the heat-conducting grooves 10 located on both the inner and outer sides of the bifurcated ribs 4. This prolongs the contact time between the hydrogen gas and the heat, ensuring the conversion effect of the hydrogen gas. The hydrogen gas flows upwards inside the hydrogen storage cylinder 1 and is then transported to the corresponding position by the cylinder head assembly 2, thus realizing the conversion of the fixed hydrogen crystals into hydrogen gas.
