Description

TECHNICAL FIELD

[0001] The utility model relates to solid hydrogen storage equipment technical field, especially in solid hydrogen storage heat exchange unit and solid hydrogen storage heat exchange device. BACKGROUND

[0002] Hydrogen is a very important industrial raw material and a clean energy, it is widely used in petrochemical industry, electronics, metallurgy and other industries, and the main hydrogen storage mode includes high pressure gaseous hydrogen storage, low temperature liquid hydrogen storage and solid hydrogen storage.

[0003] In the hydrogen production, storage and use link, how to store hydrogen safely and efficiently becomes the key to hinder the large-scale application of hydrogen energy. At present, the main hydrogen storage and transportation methods have three kinds, which are high pressure gaseous hydrogen storage, low temperature liquid hydrogen storage and solid hydrogen storage. High pressure gaseous hydrogen storage is mature, which is the most commonly used hydrogen storage method in China, but its safety is poor and the volume hydrogen storage density is low. Low temperature liquid hydrogen storage cools and liquefies hydrogen, and stores it in a vacuum insulated container, which has high cost and low energy efficiency. Solid hydrogen storage is a hydrogen storage method that hydrogen combines with hydrogen storage material to form hydride under certain pressure and temperature. Compared with gaseous and liquid hydrogen storage, solid hydrogen storage has high volume hydrogen storage density, good safety and high energy efficiency, and is a hydrogen storage technology with broad development prospects.

[0004] The chemical reaction process of solid hydrogen storage material in absorbing and releasing hydrogen is accompanied by heat effect. Heat is released when hydrogen is absorbed, and heat is absorbed when hydrogen is released. In order to realize fast and stable hydrogen absorption and release, heat exchange structure needs to be designed for solid hydrogen storage device to provide heat dissipation when hydrogen is absorbed and provide heating when hydrogen is released. At present, the solid hydrogen storage devices on the market mainly adopt two heat exchange methods: one is to design a complex heat exchange structure in the hydrogen storage tank, and the heat exchange fluid circulates outside the heat exchanger and the hydrogen storage tank, which will cause the sealing performance of the hydrogen storage tank to be poor, the safety and stability to be reduced, and the hydrogen storage material to be deteriorated when the heat exchange fluid leaks. At the same time, the heat exchange structure cannot be taken out, and the whole hydrogen storage device needs to be scrapped when it is damaged. The other is to immerse the hydrogen storage bottle in the heat exchange liquid, and exchange heat through the heat exchange liquid. Long-term immersion in the heat exchange liquid may cause corrosion of the hydrogen storage bottle, which has safety hazards. At the same time, when the heat exchange structure is damaged, it cannot be replaced modularly. UTILITY MODEL CONTENTS

The inside of each lower heat exchange module 11 and each upper heat exchange module 18 is hollow structure, two lower heat exchange modules 11 are connected one by one with two upper heat exchange modules 18, wherein the upper end of each lower heat exchange module 11 and the lower end of a corresponding upper heat exchange module 18 are in communication with each other, so that the heat exchange medium can flow into the lower end of each lower heat exchange module 11 and flow out of the upper end of the corresponding upper heat exchange module 18.

[0026] It can be understood that the lower heat exchange module 11 and the upper heat exchange module 18 of each solid-state hydrogen storage heat exchange unit are not limited to two each. A solid-state hydrogen storage heat exchange unit can also include three lower heat exchange modules 11 and three upper heat exchange modules 18, or four lower heat exchange modules 11 and four upper heat exchange modules 18, etc. Three or four upper heat exchange modules 11 are combined to form a containing space to sandwich one hydrogen storage bottle 21 between them, and three or four lower heat exchange modules 18 are combined to form a containing space to sandwich another hydrogen storage bottle 21 between them. This is not the only limitation.

[0027] In the solid-state hydrogen storage heat exchange unit of the utility model, the solid-state hydrogen storage heat exchange unit is modularly designed, and the number of hydrogen storage bottles is increased by adding solid-state hydrogen storage heat exchange units. Modular design facilitates mass production. The hydrogen storage bottle 21 is not in direct contact with the heat exchange medium, which avoids the possibility of corrosion caused by long-term immersion of the hydrogen storage bottle in the heat exchange medium. At the same time, it avoids the situation that the whole heat exchange device cannot be used due to the damage of one component.

[0028] In this embodiment, as Figures 3-4As shown, each lower heat exchange module 11 is provided with a first accommodating portion 111, and the first accommodating portions 111 of the two lower heat exchange modules 11 jointly form an accommodating space for clamping the hydrogen storage bottle 21; each upper heat exchange module 18 is provided with a second accommodating portion 181, and the second accommodating portions 181 of the two upper heat exchange modules 18 jointly form an accommodating space for clamping the hydrogen storage bottle 21; wherein the groove wall of the first accommodating portion 111 and the groove wall of the second accommodating portion 181 are both in close contact with the outer side surface of the hydrogen storage bottle 21.

[0029] The outer contour of the hydrogen storage bottle 21 corresponds to the shape of the first accommodating portion 111 / second accommodating portion 181. In the embodiment, the first accommodating portion 111 / second accommodating portion 181 can be cylindrical, and correspondingly, the hydrogen storage bottle 21 is a cylinder.

Of course, the cross section of the hydrogen storage bottle 21 in the vertical direction can also be elliptical or circular, and the first accommodating portion 111 / second accommodating portion 181 is provided in a shape corresponding to the hydrogen storage bottle 21. This is not the only limitation.

[0030] Specifically, the lower heat exchange module 11 and the upper heat exchange module 18 are both hollow structures. The contact part between the lower heat exchange module 11 and the upper heat exchange module 18 and the hydrogen storage bottle 21 is concave, which is in close contact with the hydrogen storage bottle 21. The heat exchange medium first enters the inside of the lower heat exchange module 11 from the liquid inlet end plate 12, and then flows from the lower heat exchange module 11 to the upper heat exchange module 18. The heat exchange medium exchanges heat through the hydrogen storage bottle 21 between the two lower heat exchange modules 11 and the hydrogen storage bottle 21 between the two upper heat exchange modules 18.

[0031] It should be noted that the lower heat exchange module 11 and the upper heat exchange module 18 are completely identical in structure and shape. It can be understood that the solid-state hydrogen storage heat exchange unit is composed of four heat exchange modules, and the four heat exchange modules are combined into two parts, i.e. two lower heat exchange modules 11 and two upper heat exchange modules 18. The solid-state hydrogen storage heat exchange unit as a whole can be regarded as axisymmetric.

The upper heat exchange module 18 includes an upper heat exchange body 182 and an upper communication plate 183, the inside of the upper heat exchange body 182 and the upper communication plate 183 is a hollow structure, the outer side wall of the upper heat exchange body 182 is provided with a second accommodating portion 181, the upper communication plate 183 is connected to the lower end of the upper heat exchange body 182, and the upper heat exchange body 182 and the upper communication plate 183 are in communication with each other.

[0033] Specifically, the lower communication plate 113 of each lower heat exchange module 11 is fixedly connected with the upper communication plate 183 of a corresponding upper heat exchange module 18 and communicates with each other.

[0034] Specifically, there is a heat exchange main body between the two lower heat exchange modules 11 and the two upper heat exchange modules 18. The lower heat exchange main body 112 of the lower heat exchange module 11 and the upper heat exchange main body 182 of the upper heat exchange module 18 are connected and communicated through the lower communication plate 113 and the upper communication plate 183. The heat exchange medium enters the lower heat exchange main body 112, at which time heat exchange occurs with the hydrogen storage bottle 21 located in the accommodation space enclosed by the two lower heat exchange modules 11; the heat exchange medium then flows from the lower heat exchange main body 112 to the upper heat exchange main body 182 through the lower communication plate 113 and the upper communication plate 183, at which time heat exchange occurs with the hydrogen storage bottle 21 located in the accommodation space enclosed by the two upper heat exchange modules 18.

The lower heat exchange fins 114 and the upper heat exchange fins 184 are used to increase the heat transfer area and enhance the degree of turbulence of the fluid to improve the convective heat transfer function.

[0036] By increasing the heat exchange fins on the surface of the heat exchange main body, the surface area of the heat exchanger can be significantly increased, thereby improving the heat exchange efficiency. In addition, different forms of heat exchange fins (such as straight fins, louvered fins, serrated fins, etc.) can cause strong turbulence of air in the flow channel, breaking and recombining the flow boundary layer and thermal boundary layer, further strengthening the heat exchange. This design not only improves the heat exchange efficiency, but also optimizes the space utilization, making the equipment more compact and portable.

[0037] In this embodiment, the solid-state hydrogen storage heat exchange unit further comprises a mounting plate 14 and a fan 15. The mounting plate 14 is located on one side of the solid-state hydrogen storage heat exchange unit, and the fan 15 is fixedly installed on the mounting plate 14. The fan 15 corresponds to the lower heat exchange fins 114 and the upper heat exchange fins 184. There is a gap between the mounting plate 14 and the solid-state hydrogen storage heat exchange unit.

Figures 6-7 Liquid inlet end plate 12 is used for the heat exchange medium to flow in, and liquid outlet end plate 13 is used for the heat exchange medium to flow out. Liquid inlet end plate 12 is communicated with the lower end of each lower heat exchange module 11, and liquid outlet end plate 13 is communicated with the upper end of each upper heat exchange module 18. The heat exchange medium first enters the inside of the lower heat exchange module 11 from the liquid inlet end plate 12, and then flows from the lower heat exchange module 11 to the upper heat exchange module 18, and the heat exchange medium exchanges heat through the hydrogen storage bottle 21 between the two lower heat exchange modules 11 and the hydrogen storage bottle 21 between the two upper heat exchange modules 18.

[0041] In the embodiment, liquid inlet end plate 12 has a liquid inlet 122 for the heat exchange medium to flow in, and liquid outlet end plate 13 has a liquid outlet 132 for the heat exchange medium to flow out; the solid-state hydrogen storage heat exchange device further includes a liquid inlet pipe 16 and a liquid outlet pipe 17, wherein the liquid inlet pipe 16 is connected between the liquid inlet end plate 12 and the lower end of each lower heat exchange module 11, and the liquid outlet pipe 17 is connected between the liquid outlet end plate 13 and the upper end of each upper heat exchange module 18.

[0042] Specifically, there are four liquid inlet pipes 16 and four liquid outlet pipes 17. Each of the two lower heat exchange modules 11 is connected with two liquid inlet pipes 16, and each of the two upper heat exchange modules 18 is connected with two liquid outlet pipes 17, so that the heat exchange medium can quickly and smoothly enter the solid-state hydrogen storage heat exchange unit and exchange heat with the hydrogen storage bottle 21. Of course, the skilled in the art can set the specific number of liquid inlet pipes 16 and liquid outlet pipes 17 according to the actual situation, for example, 2, 3, 4, 5, 6, etc., which is not limited here.

The hydrogen storage bottle 21 located in the accommodating space of the two upper heat exchange modules 18 can contact the groove bottom of the second groove 131.

[0044] Specifically, the liquid inlet end plate 12 and the liquid outlet end plate 13 are both hollow structures, and the heat exchange medium can flow in the liquid inlet end plate 12 and the liquid outlet end plate 13. The first groove 121 and the second groove 131 can be square grooves. The first groove 121 provided on the liquid inlet end plate 12 can fix the two lower heat exchange modules 11, and the second groove 131 provided on the liquid outlet end plate 13 can fix the two upper heat exchange modules 18. Meanwhile, the two lower heat exchange modules 11 contact the groove wall of the first groove 121, and the two upper heat exchange modules 18 contact the groove wall of the second groove 131, so as to increase the contact area for heat exchange.

[0045] Further, the liquid inlet end plate 12 has a liquid inlet 122 for the heat exchange medium to enter from outside to the inside of the liquid inlet end plate 12, and the liquid outlet end plate 13 has a liquid outlet 132 for the heat exchange medium to flow out.

[0046] The heat exchange medium enters the inside of the liquid inlet end plate 12 through the liquid inlet 122, then enters the inside of the lower heat exchange module 11 from the liquid inlet pipe 16, flows to the inside of the upper heat exchange module 18, and flows to the inside of the liquid outlet end plate 13 from the liquid outlet pipe 17, and finally flows out from the liquid outlet 132. In this process, the heat exchange medium exchanges heat with the hydrogen storage bottle 21 located between the two lower heat exchange modules 11 and the hydrogen storage bottle 21 located between the two upper heat exchange modules 18.

[0047] It should be noted that the two lower heat exchange modules 11 are not connected with each other, and the two upper heat exchange modules 18 are not connected with each other.

[0048] The heat exchange medium enters the two lower heat exchange modules 11 from the liquid inlet pipe 16 after entering the liquid inlet end plate 12, and exchanges heat with the hydrogen storage bottle 21 located in the accommodating space formed by the two lower heat exchange modules 11; then enters the two upper heat exchange modules 18 through the communication plate 113, and exchanges heat with the hydrogen storage bottle 21 located in the accommodating space formed by the two upper heat exchange modules 18; and then flows to the liquid outlet end plate 13 through the liquid outlet pipe 17 and finally flows out from the liquid outlet 132.

[0049] In the solid-state hydrogen storage heat exchange device of the embodiment, the two solid-state hydrogen storage heat exchange units are integrally arranged and communicated with each other at the liquid inlet end plate 12, and are integrally arranged and communicated with each other at the liquid outlet end plate 13. Of course, the skilled in the art can also arrange the number of solid-state heat exchange units to be 3, 4, 5, 6, etc. according to the actual situation, which is not limited here.

[0050] The liquid inlet end plate 12 and the liquid outlet end plate 13 of the two solid-state hydrogen storage heat exchange units in the embodiment are integrally arranged and communicated with each other, please refer to the structure shown in Figure 1 It can be understood that the liquid inlet end plate 12 is provided with a first groove 121 which is the same as the number of solid-state hydrogen storage heat exchange units, and the liquid outlet end plate 13 is provided with a second groove 131 which is the same as the number of solid-state hydrogen storage heat exchange units.

[0051] Specifically, the solid-state hydrogen storage heat exchange unit has two, the liquid inlet end plate 12 is provided with two first grooves 121, and the liquid outlet end plate 13 is provided with a second groove 131. There are two hydrogen storage bottles 21 for storing hydrogen in one solid-state hydrogen storage heat exchange unit. Four heat exchange modules can form a solid-state hydrogen storage heat exchange unit, and heat exchange is carried out for two hydrogen storage bottles 21 as a group.

[0052] The working principle of the heat exchange device in the embodiment is as follows:

[0053] 1. The external heat exchange medium enters the liquid inlet end plate 12 from the liquid inlet 122, is shunted at the liquid inlet end plate 12, and enters the lower heat exchange main body 112 of the lower heat exchange module 11 through the liquid inlet pipe 16;

[0054] 2. After the heat exchange medium enters the lower heat exchange main body 112 close to the liquid inlet end plate 12, it passes through the lower communication plate 113 and the upper communication plate 183 to enter the upper heat exchange main body 182, and finally flows out through the liquid outlet pipe 17;

[0055] 3. The heat exchange medium flows out from the liquid outlet pipe 17, converges at the liquid outlet end plate 13, and is discharged through the liquid outlet 132;

[0056] 4. In this process, the heat exchange medium exchanges heat with the hydrogen storage bottle 21 through the lower heat exchange module 11 and the upper heat exchange module 18, and the upper heat exchange fin 114 and the lower heat exchange fin 184 assist the hydrogen storage bottle 21 to exchange heat through the fan 15;

[0057] 5. When the solid-state hydrogen storage absorbs hydrogen, heat is released, at which time the liquid inlet 122 is cooled by cooling water, and the heat of the hydrogen storage bottle 21 is removed by circulating cooling water and turning on the fan 15 to cool the upper heat exchange fin 114 and the lower heat exchange fin 184;

[0058] 6. When solid hydrogen storage releases hydrogen, it absorbs heat. At this time, the liquid inlet 122 can be connected to the circulating water of the fuel cell. The heat generated by the operation of the fuel cell is used to heat the solid hydrogen storage. At the same time, the fan 15 uses the heat generated by the fuel cell to blow hot air onto the upper heat exchange fins 114 and the lower heat exchange fins 184 to heat the upper heat exchange fins 114 and the lower heat exchange fins 184 to assist the solid hydrogen storage in absorbing heat.

[0059] 7. Depending on the heat exchange requirements under the usage conditions, air or liquid heat exchange can be used separately.

[0060] In this embodiment, the heat exchange device can adopt a combination of air and liquid heat exchange, which increases the heat exchange capacity of the heat exchange device. At the same time, depending on the heat exchange requirements of the application scenario, liquid heat exchange or air heat exchange can be performed separately, which significantly reduces energy consumption.

[0061] It should be noted that the two hydrogen storage cylinders 21 located at the top and bottom positions in a solid hydrogen storage unit can be interconnected. When the lower hydrogen storage cylinder 21 is filled with hydrogen, the upper hydrogen storage cylinder 21, which is connected to it, continues to store hydrogen.
