Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydrogen storage technology, and more specifically, to a solid hydrogen storage and charging cabinet. Background Technology
[0002] Solid-state hydrogen storage technology has attracted widespread attention due to its high hydrogen storage density and safety. During the hydrogen filling process, the storage material releases a large amount of heat, causing the temperature of the storage tank to rise, which in turn affects the hydrogen adsorption efficiency and storage capacity. Current technologies often employ spray cooling or water bath cooling methods to dissipate heat from the storage tank.
[0003] Spray cooling consumes a large amount of water and has high requirements for water quality, which can easily lead to scaling and corrosion of equipment. Water bath cooling can effectively dissipate heat, but long-term operation requires frequent water changes or cooling of the water body. In addition, water droplets easily adhere to the surface of the hydrogen storage tank, affecting the accuracy of weighing and making it difficult to accurately determine whether the hydrogen storage tank is full.
[0004] Therefore, existing technologies suffer from problems such as complex structure, high water consumption, easy corrosion of equipment, high maintenance costs, and large weighing errors. Utility Model Content
[0005] The technical problem to be solved by this utility model is to provide a solid hydrogen storage and charging cabinet with a simple structure and good cooling effect, which addresses the shortcomings of the above-mentioned spray cooling method in the prior art, which consumes a lot of water resources, has high requirements for water quality, and is prone to scaling and corrosion of equipment.
[0006] The technical solution adopted by this utility model to solve its technical problem is: to construct a solid hydrogen storage and charging cabinet, which has the following features:
[0007] The cabinet is a rectangular prism with a hollow interior.
[0008] The cabinet is equipped with a placement assembly featuring a cavity structure.
[0009] At least one solid hydrogen storage bottle is disposed within the cavity structure of the placement component;
[0010] At least one heat insulation layer is provided on each adjacent inner wall surface of the placement component;
[0011] A cooling device is provided on the adjacent side of the placement component, and the air outlet of the cooling device is connected to the cavity structure of the placement component for circulating and supplying cold air into the cavity structure of the placement component.
[0012] The cooling capacity output by the cooling device is determined based on the heat dissipation of the solid hydrogen storage cylinder during the hydrogen filling process and the heat transfer of the wall surface of the placement component.
[0013] In some embodiments, the insulation layer is insulation cotton, glass wool, or rock wool.
[0014] In some embodiments, the cooling device employs a compressor-based refrigeration method.
[0015] In some embodiments, the cavity structure of the placement component is configured as a closed structure, and the cooling device is connected to the placement component through an air duct.
[0016] In some embodiments, the solid hydrogen storage cylinders are arranged in an array within the cavity structure of the placement assembly.
[0017] In some embodiments, the cooling device is equipped with a temperature controller for controlling the temperature within the placement assembly within a set range.
[0018] The solid-state hydrogen storage and charging cabinet of this invention includes a cabinet body with a cavity-structured placement assembly, and at least one solid-state hydrogen storage cylinder disposed within the placement assembly. At least one insulation layer is disposed on each adjacent inner wall surface of the placement assembly. A cooling device is disposed on an adjacent side of the placement assembly, with its air outlet connected to the placement assembly for circulating cool air into the assembly. The cooling output of the cooling device is determined based on the heat dissipation of the solid-state hydrogen storage cylinder during the hydrogen charging process and the heat transfer of the walls of the placement assembly. Compared with existing technologies, the use of an air-cooled circulation system eliminates the need for complex water circuits, pumps, water treatment devices, and corrosion-resistant structures required for spraying, as well as the need for large water tanks and circulating water systems in water bath systems. This simplifies the equipment structure and significantly reduces manufacturing and maintenance costs.
[0019] On the other hand, by installing a cooling device in the cabinet for forced air cooling, the cooling capacity can be precisely controlled according to the real-time heat load (heat dissipation of hydrogen storage and heat leakage of the cavity), and the temperature inside the placed components can be stably maintained within the optimal adsorption temperature range of the hydrogen storage material, thereby ensuring that the hydrogen charging process is carried out efficiently.

[0026] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0027] like Figures 1-4 As shown, in the first embodiment of the solid-state hydrogen storage and charging cabinet of this utility model, the solid-state hydrogen storage and charging cabinet 10 includes a cabinet body 110.
[0028] The cabinet 110 is a cuboid with an internal hollow structure 10a, which is used to install and place the components 120 and the cooling device 130.
[0029] The placement component 120 is formed into a square structure to support the solid hydrogen storage cylinder 140 to be filled with gas.
[0030] Cooling device 130 is used to generate cold air to cool down the heat generated in solid hydrogen storage cylinder 140 during the filling process;
[0031] Specifically, a placement component 120 is installed within the internal hollow structure 10a of the cabinet 110.
[0032] The placement assembly 120 is provided with a cavity structure 120a for installing a solid hydrogen storage bottle 140, and at least one solid hydrogen storage bottle 140 is provided in the cavity structure 120a of the placement assembly 120.
[0033] Among them, such as Figure 4 As shown, at least one insulation layer 122 is provided on the adjacent inner wall surfaces (corresponding to 120b-120e) of the placement component 120, and the insulation layer 122 is provided on the inner wall of the cavity structure 120a;
[0034] Furthermore, a cooling device 130 is provided on the adjacent side of the component 120 (e.g., Figure 5 As shown, the air outlet of the cooling device 130 is connected to the cavity structure 120a of the placement component 120, and is used to circulate and deliver cold air to the cavity structure 120s of the placement component 120 to cool the solid hydrogen storage bottle 140.
[0035] The cooling capacity output by the cooling device 130 is determined based on the heat dissipation of the solid hydrogen storage bottle 140 during the hydrogen filling process and the heat transfer of the wall surface of the placement component 120, thus the cooling of the solid hydrogen storage bottle 140 is controllable.
[0036] Using this technical solution, an air-cooled circulation system is adopted, which eliminates the need for complex water circuits, water pumps, water treatment devices and anti-corrosion structures required for spraying. It also eliminates the need for large water tanks and circulating water systems in water bath mode, which makes the equipment structure simpler and significantly reduces manufacturing and maintenance costs.
[0037] On the other hand, by installing a cooling device in the cabinet for forced air cooling, the cooling capacity can be precisely controlled according to the real-time heat load (heat dissipation of hydrogen storage and heat leakage of the cavity), and the temperature inside the placed components can be stably maintained within the optimal adsorption temperature range of the hydrogen storage material, thereby ensuring that the hydrogen charging process is carried out efficiently.
[0038] In some implementations, such as Figure 4 As shown, the loss of cold energy can be achieved by selecting insulation cotton, glass wool or rock wool as the insulation layer 122. The insulation layer set on the inner wall of the cavity structure 120a can effectively reduce the heat exchange between the cold energy and the external environment, reduce the loss of cold energy in the cooling device 130, reduce the energy consumption of the refrigeration system, and improve the overall energy efficiency.
[0039] In some implementations, such as Figure 4 As shown, the cooling device 130 adopts a compressor refrigeration method. The compressor refrigeration has high refrigeration efficiency, precise and stable temperature control, and can meet the needs of continuous and large-capacity refrigeration during hydrogen charging, ensuring the reliable operation of the system under various operating conditions.
[0040] In some implementations, such as Figure 4 As shown, the cavity structure 120a of the placement component 120 is set as a closed structure. The cooling device 130 is connected to the cavity structure 120a of the placement component 120 through the air duct 123. Multiple support plates 124 are radially arranged inside the cavity structure 120a. Multiple through holes 124a are arranged at the rear end of the support plates 124. The cold air input into the cooling device 130 is input through the air duct 123, then flows upward, and enters the placement space formed by the two support plates 124a through the through holes 124a to cool down the solid hydrogen storage cylinder 140. The cavity structure 120a combined with the air duct 123 is designed to form a complete and efficient internal circulation air duct, which can avoid cold air short-circuiting, ensure that the cold air flows evenly and effectively through each hydrogen storage cylinder, achieve uniform cooling, and eliminate local overheating.
[0041] In some implementations, such as Figure 4 As shown, the solid hydrogen storage cylinders 140 are arranged in an array on the support plate 124 inside the cavity structure 120a of the placement component 120. The array arrangement is beneficial to the organization and uniform distribution of airflow inside the cavity structure 120a, so that all hydrogen storage cylinders can obtain a consistent cooling effect. At the same time, it optimizes the space utilization and makes the hydrogen storage cabinet structure more compact.
[0042] In some embodiments, the cooling device 130 is equipped with a temperature controller (not shown) to control the temperature inside the placement component 120 within a set range. The temperature controller enables automated temperature control, eliminating the need for manual intervention. This ensures that the temperature is always maintained within the range where the hydrogen storage material performs optimally, guaranteeing both the hydrogen charging speed and capacity, and improving the intelligence level and ease of operation of the equipment.
[0043] The embodiments of the present invention have been described above with reference to the accompanying drawings. However, the present invention is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the present invention without departing from the spirit and scope of the claims. All of these forms are within the protection scope of the present invention.
