Description

Technical Field

[0001] This invention relates to the field of solid-state hydrogen storage technology, and in particular to an on-board low-pressure solid-state hydrogen storage heat exchange device and method. Background Technology

[0002] Hydrogen energy is an abundant, green, low-carbon, and widely applicable secondary energy source. It facilitates the large-scale consumption of renewable energy sources such as wind and solar power, enabling grid peak shaving and energy storage. Secondly, its production also promotes syngas generation, which is beneficial for developing alternative fuel production routes, improving fuel supply in remote areas, and promoting social, economic, and environmental development. Furthermore, as a clean energy source, hydrogen energy helps reduce the proportion of fossil fuels, improves the level of clean development, and simultaneously builds a multi-energy complementary energy supply system, achieving energy transformation and upgrading.

[0003] However, moving hydrogen is quite challenging. Due to hydrogen's low density and high-pressure requirements, its storage and transportation costs are relatively high, necessitating the construction of complex hydrogen infrastructure. Transferring hydrogen requires substantial investment, even in small quantities. Compared to high-pressure hydrogen storage, low-pressure solid-state hydrogen storage offers relatively better safety and is not limited by hydrogen storage stations. However, the charging and discharging of low-pressure solid-state hydrogen involves energy release and absorption, making the heat exchange system a crucial component of the entire hydrogen storage system.

[0004] Therefore, we urgently need to study an on-board low-pressure solid hydrogen storage heat exchange device and its method. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a vehicle-mounted low-pressure solid-state hydrogen storage heat exchange device and method, which solves the technical problems of poor safety, complex and costly equipment, and inconvenience in moving existing high-pressure hydrogen storage devices. It reduces the safety and complexity of hydrogen storage devices caused by high pressure, while achieving portability, thus facilitating the storage and transportation of hydrogen energy.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a vehicle-mounted low-pressure solid hydrogen storage heat exchange device, including a trailer platform, a solid hydrogen storage module installed on the trailer platform, a container module for protecting the solid hydrogen storage module installed on the trailer platform, a heat exchange module for heat dissipation and heat supply during hydrogen charging and discharging of the solid hydrogen storage module, and an electrical system for controlling the entire solid hydrogen storage heat exchange system.

[0007] The solid-state hydrogen storage module includes an array of water tanks mounted on the trailer deck, and the water tanks are filled with heat exchange fluid. Solid-state hydrogen storage rods are installed in the array inside the water tanks. Gas pipes are installed at the rear end of the solid-state hydrogen storage rods. Multiple gas pipes are connected in series to form a hydrogen manifold. A hydrogen gas pipe is installed at the junction of the hydrogen manifold. An external hydrogen gas valve is installed on the hydrogen gas pipe.

[0008] As a further optimization of the present invention, the back of the water tank is provided with a corresponding insertion cavity for the solid hydrogen storage rod, and the end face of the insertion cavity is provided with an annular buckle to limit and fix the solid hydrogen storage rod.

[0009] As a further optimization of the present invention, the water tank is equipped with a water tank vent valve, and the bottom and top sides of the front of the water tank are respectively equipped with a liquid inlet and a liquid outlet.

[0010] As a further optimization of the present invention, the container module includes a container frame installed on the trailer board and located outside the solid hydrogen storage module. A central partition bracket is installed inside the container frame above the solid hydrogen storage module. An air inlet grille is installed on the container frame, and container doors are symmetrically installed on both the front and rear sides of the container frame.

[0011] As a further optimization of the present invention, the heat exchange module includes a heat exchange unit installed on the central partition support, and the heat exchange unit is connected to the water tank through a pipeline. A guide air duct is installed on the top of the heat exchange unit, and a non-powered wind cap for assisting in the discharge of escaping hydrogen is installed on the top of the container frame.

[0012] As a further optimization of the present invention, the pipeline is divided into an inlet pipe and a return pipe, which are respectively connected to the inlet port at the bottom front of the water tank and the outlet port at the top side.

[0013] As a further optimization of the present invention, the multiple heat exchange modules are respectively installed on the central support corresponding to multiple solid hydrogen storage module arrays.

[0014] As a further optimization of the present invention, the electrical system includes a control box installed on the container frame, the control box having multiple electrical cables installed inside, and the electrical cables being electrically connected to the heat exchange unit, with an external power strip located on one side of the container frame installed at the other end.

[0015] A method for using an on-board low-pressure solid hydrogen storage heat exchanger includes the following steps:

[0016] S1: First, insert the solid hydrogen storage rod into the insertion cavity on the water tank and lock the solid hydrogen storage rod with the ring buckle. Then, connect the gas pipes to the solid hydrogen storage rods respectively, and connect them in series to form a hydrogen manifold, which is then connected to the hydrogen gas pipe. Install an external hydrogen gas valve at the junction of the two for control.

[0017] S2: First, hoist the heat exchange module onto the internal partition bracket of the container, then hoist the container module onto the top of the solid hydrogen storage module to completely cover it. Then, connect the two ends of the liquid inlet pipe and the return pipe in the pipeline to the heat exchange unit and the water tank respectively, and disperse and discharge the exhaust gas generated by the operation of the heat exchange unit through the guide air duct.

[0018] S3: Next, the electrical system will be installed on the container module, and the electrical cables will be connected to the heat exchanger unit. Once the control box is powered on and issues a command, the target temperature of the heat exchanger unit will be set to 60°C and started. The heat exchanger unit will start the compressor to transfer heat from the air to heat the heat exchange liquid through a reverse Carnot cycle, guide the air duct to discharge the exhaust gas, start the water pump to input the heated heat exchange liquid into the water tank through the pipeline, so that the solid hydrogen storage rod absorbs heat and releases hydrogen gas. Open the external hydrogen gas valve and output the gas to the outside through the hydrogen gas pipe.

[0019] S4: During hydrogen charging, the control box is powered on and issues a command to set the target temperature of the heat exchanger unit to 10℃ and start it. The heat exchanger unit starts the compressor to transfer heat from the heat exchanger liquid to the air through the Carnot cycle, guides the air duct to discharge the exhaust gas, and starts the water pump to input the cooled heat exchanger liquid into the water tank through the pipeline. This dissipates and cools the solid hydrogen storage rods generated by hydrogen charging through the hydrogen gas pipe, ensuring the hydrogen charging and discharging work is carried out. During this process, all container doors are opened to facilitate the discharge of exhaust gas.

[0020] By employing the above technical solution, the present invention provides an on-board low-pressure solid-state hydrogen storage heat exchange device and method, which has at least the following beneficial effects:

[0021] 1. This invention significantly reduces the complexity of existing high-pressure hydrogen storage equipment by modularizing, simplifying, and lightweighting the solid-state hydrogen storage heat exchange system. This reduces costs while achieving portability, and it is safer and more reliable than high-pressure hydrogen storage, providing convenience for hydrogen energy storage and transportation. Its heat pump heat exchange operation also reduces the energy consumption of hydrogen charging and discharging.

[0022] 2. This invention heats the heat exchange liquid using a heat exchange unit and circulates it with the heat exchange liquid in the water tank via a water pump, continuously providing heat to the solid hydrogen storage rod in the water tank. This stabilizes the hydrogen release equilibrium pressure of the solid hydrogen storage rod, preventing a decrease in the hydrogen release equilibrium pressure, which could lead to a decrease in the hydrogen release rate or even a complete cessation of hydrogen release.

[0023] 3. This invention uses a heat exchange unit to cool the heat exchange fluid. Similarly, the heat exchange fluid in the water tank is circulated by a water pump. The heat generated when the solid hydrogen storage rod absorbs hydrogen in the water tank is absorbed by the low-temperature heat exchange fluid, so as to keep the hydrogen absorption equilibrium pressure of the solid hydrogen storage rod stable and avoid the hydrogen absorption equilibrium pressure from rising, which would lead to a decrease in hydrogen absorption efficiency or even stop hydrogen absorption.

[0024] 4. The heat exchange system in this invention has a single unit cooling power greater than 40KW, a single unit heating power greater than 40KW, and a total heating and cooling power of 160KW, which can achieve a hydrogen charging and discharging efficiency of 10Kg / h.

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1

[0039] Given the current limitations of existing high-pressure hydrogen storage technologies, such as poor safety, complex and costly equipment, and limited portability, this embodiment provides a vehicle-mounted low-pressure solid-state hydrogen storage heat exchange device and method. Please refer to [link / reference needed]. Figures 1-5 This embodiment provides a vehicle-mounted low-pressure solid-state hydrogen storage heat exchange device, which can reduce the safety risks and complexity of hydrogen storage equipment caused by high pressure, while also achieving portability, thus facilitating the storage and transportation of hydrogen energy. The vehicle-mounted low-pressure solid-state hydrogen storage heat exchange device includes a trailer platform 1, a solid-state hydrogen storage module 2 mounted on the trailer platform 1, and a container module 3 protecting the solid-state hydrogen storage module 2. The container module 3 contains a heat exchange module 4 that dissipates heat and provides heat during hydrogen charging and discharging of the solid-state hydrogen storage module 2. The container module 3 also contains an electrical system 5 that controls the entire solid-state hydrogen storage heat exchange system. The container module 3 protects the solid-state hydrogen storage module 2 and provides support for the heat exchange module 4. When the solid-state hydrogen storage module 2 absorbs or discharges hydrogen, the heat exchange module 4 dissipates the heat generated during hydrogen absorption and provides heat during hydrogen discharging, ensuring the normal operation of the solid-state hydrogen storage module 2.

[0040] Because existing high-pressure hydrogen storage technology has poor safety and is complex and costly, this device is equipped with a solid-state hydrogen storage module 2. The solid-state hydrogen storage module 2 includes a water tank 21 array mounted on the trailer plate 1, and the water tank 21 is filled with heat exchange fluid. Solid-state hydrogen storage rods 22 are arrayed and installed in the water tank 21. Gas pipes 23 are installed at the rear end of the solid-state hydrogen storage rods 22. Multiple gas pipes 23 are connected in series to form a hydrogen manifold 24. A hydrogen gas pipe 25 is installed at the junction of the hydrogen manifold 24. A hydrogen external gas valve 26 is installed on the hydrogen gas pipe 25. Low-pressure hydrogen storage is achieved by using Ti-Mn alloy for adsorption through the solid-state hydrogen storage rods 22, which is safer and more reliable than high-pressure hydrogen storage.

[0041] To prevent the solid hydrogen storage rod 22 from shaking or even falling off during movement, the device has corresponding insertion cavities for the solid hydrogen storage rod 22 arrayed on the back of the water tank 21. Annular buckles 27 are installed on the end faces of the insertion cavities to limit and fix the solid hydrogen storage rod 22. A water tank vent valve 28 is installed on the water tank 21, and inlet and outlet ports are respectively installed on the bottom and top sides of the front of the water tank 21. The solid hydrogen storage rod 22 is fixed in the insertion cavities on the water tank 21 by the annular buckles 27. The insertion cavities are constructed of thermally conductive support partitions, thereby improving the heat exchange efficiency of the solid hydrogen storage rod 22. When heat exchange fluid is initially injected into the water tank 21, the gas inside the water tank 21 is released through the water tank vent valve 28.

[0042] The exposed solid hydrogen storage module 2 is easily damaged by bumps and knocks. Therefore, the device is also equipped with a container module 3. The container module 3 includes a container frame 31 installed on the trailer platform 1 and located outside the solid hydrogen storage module 2. A central partition bracket 32 ​​is installed inside the container frame 31 above the solid hydrogen storage module 2. An air inlet grille 33 is installed on the container frame 31, and container doors 34 are symmetrically installed on both the front and rear sides of the container frame 31. The container frame 31 provides a certain degree of protection for the solid hydrogen storage module 2. The central partition bracket 32 ​​provides support and installation interface for the heat exchange module 4 and the electrical system 5 and is the core load-bearing structure. The air inlet grille 33 provides an air intake channel for the heat exchange unit 41.

[0043] The heat exchange fluid in the water tank 21 alone is insufficient to dissipate the heat generated when the solid hydrogen storage rod 22 is filled with hydrogen. Furthermore, the solid hydrogen storage rod 22 requires continuous heat absorption when releasing hydrogen, and the heat stored in the heat exchange fluid in the water tank 21 is insufficient to support the heat supply. Therefore, the device also includes a heat exchange module 4. The heat exchange module 4 includes a heat exchange unit 41 mounted on the central support bracket 32, and the heat exchange unit 41 is connected to the water tank 21 via a pipe 42. A guide air duct 43 is installed on the top of the heat exchange unit 41, and a non-powered vent cap 44 is installed on the top of the container frame 31 to assist in the discharge of escaping hydrogen. The pipe 42 is divided into an inlet pipe 421 and a return pipe 422, which are respectively connected to the bottom inlet port on the front side and the top outlet port on the side of the water tank 21. Multiple heat exchange modules 4 are respectively installed on the central support bracket 32, corresponding to multiple solid hydrogen storage modules 2 arrays. When the solid hydrogen storage rod 22 releases hydrogen and absorbs heat, the heat exchange unit 41 is started and its target temperature is set to 60℃. The heat exchange unit 41 starts the compressor to transfer heat from the air to heat the heat exchange fluid through a reverse Carnot cycle, and the heated heat exchange fluid is pumped into the water tank 21 through the pipeline 42 by the water pump, continuously providing heat to the solid hydrogen storage rod 22. When the solid hydrogen storage rod 22 fills with hydrogen and releases heat... The heat exchanger unit 41 is started and its target temperature is set to 10℃. The compressor of the heat exchanger unit 41 is started to transfer heat from the heat exchanger liquid to the air through the Carnot cycle, thereby continuously supplying low temperature heat exchanger liquid to the water tank 21 to absorb and cool the heat generated when the solid hydrogen storage rod 22 is filled with hydrogen. The cooling power of a single unit of this heat exchanger system is greater than 40KW, the heating power of a single unit is greater than 40KW, and the total heating and cooling power reaches 160KW, which can achieve a hydrogen filling and releasing efficiency of 10Kg / h.

[0044] The electrical system 5 includes a control box 51 installed on the container frame 31. Multiple electrical cables 52 are installed inside the control box 51, and the electrical cables 52 are electrically connected to the heat exchange unit 41. The other end of each cable is connected to an external power strip 53 located on one side of the container frame 31. The device is connected to an external power source through the external power strip 53, and the operation of the device is controlled through the control box 51.

[0045] Example 2

[0046] A method for using an on-board low-pressure solid hydrogen storage heat exchanger includes the following steps:

[0047] S1: First, insert the solid hydrogen storage rod 22 into the insertion cavity on the water tank 21 and lock the solid hydrogen storage rod 22 with the ring buckle 27. Then, connect the gas pipe 23 to the solid hydrogen storage rod 22 respectively, and connect them in series to form a hydrogen manifold 24, which is then connected to the hydrogen gas pipe 25. Install the external hydrogen gas valve 26 at the junction of the two for control.

[0048] S2: Then, first, the heat exchange module 4 is hoisted onto the internal partition bracket 32 ​​of the container, and then the container module 3 is hoisted and installed on top of the solid hydrogen storage module 2 to completely cover it. Then, the two ends of the liquid inlet pipe 421 and the return pipe 422 in the pipeline 42 are connected to the heat exchange unit 41 and the water tank 21 respectively, and the exhaust gas generated by the operation of the heat exchange unit 41 is dispersed and discharged through the guide air duct 43.

[0049] S3: Next, the electrical system 5 will be installed on the container module 3, and the electrical cable 52 will be connected to the heat exchange unit 41. After the control box 51 is powered on and issues a command, the target temperature of the heat exchange unit 41 will be set to 60°C and started. The heat exchange unit 41 will start the compressor to transfer heat from the air to heat the heat exchange liquid through the reverse Carnot cycle, guide the air duct 43 to discharge the exhaust gas, start the water pump to input the heated heat exchange liquid into the water tank 21 through the pipeline 42, so that the solid hydrogen storage rod 22 absorbs heat and releases hydrogen gas, and open the hydrogen external gas valve 26 to output gas to the outside through the hydrogen gas pipe 25.

[0050] S4: During hydrogen charging, the control box 51 is powered on and issues a command to set the target temperature of the heat exchanger unit 41 to 10°C and start it. The heat exchanger unit 41 starts the compressor to transfer heat from the heat exchanger liquid to the air through the Carnot cycle, guides the air duct 43 to discharge the exhaust gas, and starts the water pump to input the cooled heat exchanger liquid into the water tank 21 through the pipeline 42. This dissipates and cools the solid hydrogen storage rod 22 through the hydrogen gas pipe 25, ensuring the hydrogen charging and discharging work is carried out. During this process, the container door 34 is fully opened to facilitate the discharge of exhaust gas.
