[0039] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0040] The following is for reference. Figures 1-4 This application describes a solid-state hydrogen storage module according to an embodiment of the present application.

[0041] This embodiment discloses a solid-state hydrogen storage module that can be applied to clean energy storage, using solid-state hydrogen storage technology to achieve efficient hydrogen storage and heat management.

[0042] Please see Figure 1 The solid hydrogen storage module includes: a first partition 210, a heat dissipation part 120, and a accommodating part 130;

[0043] The first partition 210 is provided between the heat dissipation part 120 and the accommodating part 130 to separate the heat dissipation part 120 and the accommodating part 130.

[0044] The solid-state hydrogen storage module can have at least two of the following specific structural forms:

[0045] Firstly, the solid-state hydrogen storage module also includes: a housing 100;

[0046] The housing 100 has an inner cavity, and a first partition 210 is provided in the inner cavity of the housing 100. The first partition 210 divides the inner cavity of the housing 100 to form a heat dissipation part 120 and a receiving part 130 (see...). Figure 2 and Figure 3 ).

[0047] The accommodating part 130 is used to house the hydrogen storage cylinder 300; the heat dissipation part 120 is connected to the external environment.

[0048] Secondly, the solid-state hydrogen storage module also includes: a housing 100;

[0049] The housing 100 has an inner cavity, the first partition 210 is a side wall of the inner cavity of the housing 100, the accommodating part 130 is a region of the inner cavity of the housing 100, and the heat dissipation part 120 is a region outside the inner cavity of the housing 100.

[0050] The accommodating part 130 is used to house the hydrogen storage cylinder 300; the heat dissipation part 120 is located in the external environment.

[0051] In actual implementation, the housing 100 can be formed by multiple mounting plates 110. For example, the housing 100 can be formed by six mounting plates 110 to form a cuboid. It should be noted that in the second embodiment, a certain mounting plate 110 can also be equivalent to the first partition 210.

[0052] It should be noted that the containment 130 is used to accommodate multiple hydrogen storage cylinders 300. The hydrogen storage cylinders 300 use hydrogen storage materials to store hydrogen in the form of metal hydrides. During the hydrogen absorption process, the hydrogen storage materials of the hydrogen storage cylinders 300 undergo an exothermic reaction at a specific temperature to generate metal hydrides, thereby achieving hydrogen absorption. This will directly lead to an increase in the temperature inside the containment 130.

[0053] This application connects to the external environment through the heat dissipation section 120, allowing heat exchange between the heat dissipation section 120 and the air inside the accommodating section 130. Specifically, the first partition section 210 is provided with a spaced-out air outlet 211 and a return air outlet 212, with the return air outlet 212 located above the air outlet 211. More specifically, the heat dissipation section 120 is equipped with a fan configured to deliver airflow into the accommodating section 130 through the air outlet 211 and / or draw airflow from the accommodating section 130 through the return air outlet 212, thereby allowing heat exchange between the airflow and the external environment. This effectively removes the heat generated by the hydrogen storage tank 300 during hydrogen storage, maintaining the hydrogen storage reaction under ideal temperature conditions.

[0054] In the above embodiments of this application, the fan can blow out a low-temperature airflow through the air outlet 211. This low-temperature airflow absorbs the heat released by the hydrogen storage tank 300 as it passes through the containment part 130, gradually heating up to form a high-temperature airflow. Since the high-temperature airflow is lighter and has a natural upward characteristic, this application places the return air outlet 212 above the air outlet 211, making it easier for the high-temperature airflow to enter the return air outlet 212 and ultimately flow from the heat dissipation part 120 to the external environment. This design effectively removes the heat generated by the hydrogen storage tank 300 during hydrogen storage, ensuring that the hydrogen storage process remains within a reasonable temperature range and preventing excessively high temperatures from affecting hydrogen storage efficiency.

[0055] Specifically, the fan includes a first fan and a second fan. The first fan is positioned directly opposite the air outlet 211 and is used to deliver airflow into the container 130 through the air outlet 211. The second fan is positioned directly opposite the return air inlet 212 and is used to draw airflow from the container 130 through the return air inlet 212. With this arrangement, the low-temperature airflow flows in from the air outlet 211 at the bottom of the container 130, exchanges heat with the air inside the container 130 to form a high-temperature airflow, and then flows out from the return air inlet 212 at the top of the container 130. This effectively removes the heat released by the hydrogen storage tank 300 during the hydrogen storage reaction, ensuring that the temperature inside the container 130 is maintained within a reasonable range. In actual implementation, the first fan can be a cooling fan, including but not limited to an electronic cooling fan, a compressor cooling fan, or a centrifugal air-cooled cooling fan, and the second fan can be an exhaust fan.

[0056] Please see Figure 3 and Figure 4 In some embodiments, the housing 100 is further provided with a second partition 220, which serves to separate the accommodating portion 130, dividing the interior of the accommodating portion 130 into a first accommodating portion 131 and a second accommodating portion 132. The second partition 220 also serves to support the hydrogen storage cylinder 300; for example, the front end of the hydrogen storage cylinder 300 can pass through the second partition 220. Specifically, the second partition 220 has a through hole, through which the front end of the hydrogen storage cylinder 300 passes. More specifically, the cavity wall of the second accommodating portion 132 is provided with thermal insulation material; and / or, the wall of the through hole of the second partition 220 is provided with thermal insulation material, through which the front end of the hydrogen storage cylinder 300 passes and abuts against the thermal insulation material. This better retains the low-temperature airflow blown out by the fan, preventing excessive loss of the low-temperature airflow. The thermal insulation material can be thermal insulation cotton.

[0057] Please see Figure 3 For example, the second accommodating part 132 is provided with a mounting bracket 1321, and a connector 1322 is provided on the mounting bracket 1321. The mounting bracket 1321 is connected to the hydrogen storage cylinder 300 one by one through the connector 1322.

[0058] In actual implementation, the connector 1322 includes a first snap-fit ​​portion and a second snap-fit ​​portion, with one end of the first snap-fit ​​portion and the second snap-fit ​​portion fixedly connected. The hydrogen storage cylinder 300 is clamped between the other ends of the first snap-fit ​​portion and the second snap-fit ​​portion to achieve clamping and fixing of the hydrogen storage cylinder 300. Specifically, each hydrogen storage cylinder 300 corresponds to two connectors 1322, with the first snap-fit ​​portion and the second snap-fit ​​portion of one connector 1322 clamping the hydrogen storage cylinder 300 near the front end, and the first snap-fit ​​portion and the second snap-fit ​​portion of the other connector 1322 clamping the rear end of the hydrogen storage cylinder 300.

[0059] To optimize the space utilization and arrangement of the hydrogen storage cylinders 300, multiple hydrogen storage cylinders 300 are arranged parallel to each other and spaced apart. At least two hydrogen storage cylinders 300 can be arranged vertically to fully utilize the height space within the second accommodating portion 132, and at least two hydrogen storage cylinders 300 can also be arranged horizontally to fully utilize the width space within the second accommodating portion 132, meeting the needs of different application scenarios. Specifically, three hydrogen storage cylinders 300 can be arranged vertically, and four hydrogen storage cylinders 300 can be arranged horizontally.

[0060] Please see Figure 3 and Figure 4 In actual implementation, the housing 100 is provided with a mounting plate 110, on which a first heat exchange port 112 and a second heat exchange port 113 are provided, and the first heat exchange port 112 and the second heat exchange port 113 are in communication with the heat dissipation part 120. The first heat exchange port 112 is located above the second heat exchange port 113, which is conducive to the flow of air.

[0061] It should be noted that the first accommodating part 131 is equipped with a piping assembly 1311, and each hydrogen storage cylinder 300 is connected to the piping assembly 1311 by piping. The piping assembly 1311 is equipped with a control valve group 1312, which is used to control the opening and closing of the hydrogen storage cylinder 300 filling (see...). Figure 4 ).

[0062] Please see Figure 1 For example, the housing 100 also includes a switch door 111, the inner side of which faces the first receiving portion 131. In use, the switch door 111 can be rotated outwards relative to the housing 100 to open, and the mounting plate 110 can also be rotated inwards relative to the housing 100 to close the first receiving portion 131. This facilitates maintenance personnel in performing maintenance on the control valve assembly 1312 and piping assembly 1311 within the first receiving portion 131.
