Description

Technical fields:

[0001] This utility model relates to the field of solid-state hydrogen storage technology, and in particular to a serpentine heat dissipation channel storage structure for a hydrogen storage alloy. Background technology:

[0002] Currently, in the field of hydrogen solid-state batteries, hydrogen is generally stored by embedding a hydrogen storage alloy inside a hydrogen storage tank. The hydrogen storage alloy is a metal that can absorb hydrogen and form chemical bonds with it. The hydrogen storage alloy can absorb and release hydrogen according to temperature changes. The form of the hydrogen storage alloy includes flakes or powder. When absorbing or releasing hydrogen, the hydrogen storage tank needs to be heated or cooled. Currently, the hydrogen storage alloy is generally placed directly inside the hydrogen storage tank. During heating, uneven heating can occur, which can easily lead to thermal runaway caused by local overheating during the hydrogen release process. This results in uneven reaction, thermal stress concentration, premature termination of the reaction, material degradation, and other adverse effects. The hydrogen absorption and release efficiency is low, and it also affects the lifespan of the hydrogen storage alloy. There is currently no good solution to the above problems.

[0003] In summary, the aforementioned problems with existing hydrogen storage alloys during the storage process have become urgent technical challenges that need to be addressed in the industry. Utility Model Content:

[0004] To overcome the shortcomings of the prior art, this utility model provides a serpentine heat dissipation channel storage structure for hydrogen storage alloy, which solves the problem of local overheating caused by uneven heating of hydrogen storage alloy in previous hydrogen storage cylinders.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A serpentine heat dissipation channel storage structure for hydrogen storage alloy includes several storage units stacked sequentially. Each storage unit includes a base plate with side plates fixed to both sides. Several vertically arranged serpentine wall plates are fixed to the upper surface of the base plate, with their ends abutting the side plates. The serpentine wall plates have serpentine heat dissipation channels inside, and the side plates each have straight channels communicating with the serpentine heat dissipation channels. The ends of the side plates have fluid inlets and fluid outlets. Several mounting slots for mounting sheet-like hydrogen storage alloys or directly holding powdered hydrogen storage alloys are provided between adjacent serpentine wall plates. The top of the uppermost storage unit has a top plate, and the top plate and the base plate of each storage unit are tightened and fixed together by several long bolts.

[0007] The base plate, side plates, serpentine wall panels, and top plate are all made of metal.

[0008] The base plate and side plate, the base plate and serpentine wall panel, and the side plate and serpentine wall panel are welded and fixed or integrally formed.

[0009] The mounting groove is designed to fit the shape of the sheet-like hydrogen storage alloy.

[0010] The sheet-like hydrogen storage alloy or powdered hydrogen storage alloy is in contact with the serpentine wall plates on both sides.

[0011] The present invention adopts the above solution and has the following advantages:

[0012] Composed of several stacked storage units, modules with different numbers of layers are available according to customer needs. They are simply tightened and fixed with long bolts, making assembly simple and easy to operate. Each storage unit has several vertically arranged serpentine wall panels fixed to its base plate. These serpentine wall panels contain serpentine heat dissipation channels, which connect to straight channels in the side panels. The ends of the side panels have fluid inlets and outlets, allowing heat or cold sources to be introduced and distributed to the serpentine heat dissipation channels via the straight channels to heat or cool the serpentine wall panels. The serpentine wall panels can quickly conduct heat to the sheet-like or powdered hydrogen storage alloys, ensuring that each sheet-like hydrogen storage alloy is evenly in contact with the serpentine wall panels. This results in uniform heating of the sheet-like or powdered hydrogen storage alloys, preventing thermal runaway caused by localized overheating during hydrogen release, improving the hydrogen absorption and release efficiency of the sheet-like or powdered hydrogen storage alloys, and extending their service life.

[0016] In the diagram, 1 is the base plate, 2 is the side plate, 3 is the serpentine wall panel, 4 is the serpentine heat dissipation channel, 5 is the straight channel, 6 is the fluid inlet, 7 is the fluid outlet, 8 is the sheet-like hydrogen storage alloy, 9 is the mounting groove, and 10 is the top plate. Detailed implementation method:

[0017] To clearly illustrate the technical features of this solution, the present invention will be described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0018] like Figure 1-3As shown, a serpentine heat dissipation channel storage structure for a hydrogen storage alloy includes several storage units stacked sequentially. Each storage unit includes a base plate 1, with side plates 2 fixed to both sides of the base plate 1. Several vertically arranged serpentine wall plates 3 are fixed to the upper surface of the base plate 1, with their ends connected to the side plates 2. A serpentine heat dissipation channel 4 is provided within the serpentine wall plate 3, significantly increasing the flow path length of the fluid within the serpentine heat dissipation channel 4. The fluid used for cooling or heating travels longer within the serpentine wall plate 3, allowing more time to release or absorb heat. The serpentine heat dissipation channel 4 forces the fluid to flow sequentially through... Each area in contact with the sheet-like hydrogen storage alloy 8 ensures a relatively uniform temperature distribution on the heat source surface. Straight channels 5 connected to each serpentine heat dissipation channel 4 are provided in the inner side plates 2. Fluid inlets 6 and fluid outlets 7 are provided at the ends of the side plates 2. Several mounting slots 9 for installing the sheet-like hydrogen storage alloy 8 or for directly holding the powdered hydrogen storage alloy are provided between two adjacent serpentine wall plates 3. A top plate 10 is provided on the top of the uppermost storage unit. The top plate 10 and the bottom plate 1 of each storage unit are tightened and fixed by several long bolts. The long bolts can be set at the four corners of the bottom plate 1 and the top plate 10. After tightening by screwing nuts, they form a whole.

[0019] The bottom plate 1, side plate 2, serpentine wall plate 3 and top plate 10 are all made of metal materials, which have better heat conduction effect, and the fluid can quickly exchange heat with the hydrogen storage alloy through the serpentine wall plate 3.

[0020] The base plate 1 and the side plate 2, the base plate 1 and the serpentine wall panel 3, and the side plate 2 and the serpentine wall panel 3 are welded and fixed or integrally formed.

[0021] The mounting groove 9 is matched with the shape of the sheet-like hydrogen storage alloy 8 to prevent the sheet-like hydrogen storage alloy 8 from shaking in the mounting groove 9, ensuring stability and reliability during transportation. The shape of the sheet-like hydrogen storage alloy 8 can be various shapes such as round, elliptical, square, and rhomboid.

[0022] The sheet-like hydrogen storage alloy 8 or the powdered hydrogen storage alloy comes into contact with the serpentine wall plates 3 on both sides, which facilitates better heat exchange between the sheet-like hydrogen storage alloy 8 and the serpentine wall plates 3.

[0023] Working principle:

[0024] In use, the entire assembly of this utility model is placed inside the hydrogen storage tank for easy transportation. When hydrogen needs to be absorbed or released, the fluid from the heat source or cold source can enter the straight flow channel 5 of one side plate 2 through the fluid inlet 6, and then be distributed to each serpentine heat dissipation channel 4 through the straight flow channel 5 to directly heat or cool the serpentine wall plate 3. The serpentine wall plate 3 can quickly conduct heat to the sheet-like hydrogen storage alloy 8 or the powdered hydrogen storage alloy, and each sheet-like hydrogen storage alloy 8 can be evenly contacted by the serpentine wall plate 3, so that the sheet-like hydrogen storage alloy 8 or the powdered hydrogen storage alloy is heated evenly, avoiding thermal runaway caused by local overheating during the hydrogen release process, and improving the hydrogen absorption and release efficiency of the sheet-like hydrogen storage alloy 8 or the powdered hydrogen storage alloy. After the fluid travels along the serpentine heat dissipation channel 4, it enters the straight flow channel 5 of the other side plate 2, and finally is discharged outward through the fluid outlet 7 for circulation.

[0025] The above specific embodiments should not be construed as limiting the scope of protection of this utility model. For those skilled in the art, any alternative improvements or modifications made to the embodiments of this utility model shall fall within the scope of protection of this utility model.

[0026] Any aspects of this utility model not described in detail are known to those skilled in the art.
