Description

Technical Field

[0001] The present invention relates to the field of hydrogen storage, and in particular to a solid-state hydrogen storage device. Background Art

[0002] Solid-state hydrogen storage refers to the storage of hydrogen in solid materials by utilizing the physical and chemical adsorption of hydrogen by the material. During the hydrogen absorption process, the alloy hydrogen storage material undergoes an exothermic reaction under a certain temperature and hydrogen pressure to absorb hydrogen and generate metal hydrides. During the hydrogen release process, the metal hydride undergoes an endothermic reaction under heating to release the absorbed hydrogen.

[0003] The current solid-state hydrogen storage heat exchange type mainly adopts water jacket cooling technology. The main principle of water jacket cooling technology is to use a water tank to integrate the coolant and hydrogen storage bottle into a box, and to conduct heat exchange with the solid-state hydrogen storage through coolant circulation. The heat transfer performance is poor and the coolant redundancy is large. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a solid-state hydrogen storage device.

[0014] Furthermore, the hydrogen bottle support includes a wing plate, a waist plate and a rib plate. The waist plate is semi-circular, and the waist plates are arranged opposite to each other. The closed ends of the arcs face inward and are fixedly welded to each other through the rib plates, and the open ends of the arcs face outward. The wing plates are fixedly welded to the open ends of the arcs and the rib plates of the waist plates respectively. The waist plate and the hydrogen storage bottle are fixedly bonded by a heat-conductive structural adhesive. The wing plate is one of the outer surfaces of the solid-state hydrogen storage device.

[0015] Furthermore, the materials of the wing plate, the waist plate and the rib plate are all aluminum alloy.

[0016] Furthermore, a limiting mechanism for limiting the hydrogen quick-connect connector is provided at the middle position of the top of the box.

[0017] Furthermore, the box body is composed of a bottom shell, a middle shell, and a top shell assembled from bottom to top.

[0018] Furthermore, the bottom shell, middle shell and top shell are all made of light alloy or engineering plastic.

[0019] Furthermore, part or all of the bottom shell, the middle shell, and the top shell are fixedly connected to the hydrogen bottle support.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] (1) Through the heat conduction combination design of the hydrogen bottle support and the hydrogen storage bottle, the thermal interaction surface of the hydrogen storage device is changed from the arc shape of the hydrogen storage bottle to the plane of the hydrogen bottle support, which facilitates the use of thermal management components such as water cooling plates in the heat transfer interaction process, thereby increasing the heat transfer performance and thermal interaction efficiency.

[0023] (2) Through the packaging and integration of the box, the compact layout of the hydrogen storage bottle is achieved.

[0024] (3) The hydrogen pipeline is integrated and the double-bottle group can be quickly connected when storing or releasing gas.

[0025] (4) The hydrogen storage bottles of the two bottle groups form a unit, which can be used as the basic unit of a large-capacity solid-state hydrogen storage device through modular design.

[0026] (5) The box design is more beautiful and portable than the gas cylinder, and is easy to disassemble and replace, making it convenient for multiple groups of devices to be placed together and have unified thermal interaction. BRIEF DESCRIPTION OF THE DRAWINGS
