Description

Technical Field

[0001] This utility model relates to the field of locomotive power technology, specifically to a locomotive hydrogen power module. Background Technology

[0002] Hydrogen energy is clean and low-carbon, and its utilization has enormous potential in promoting the green and low-carbon transformation of energy-consuming sectors such as transportation and industry, as well as high-energy-consuming and high-emission industries. Enhancing the development and application of hydrogen energy can actively promote innovation in technology, products, applications, and business models, focus on breaking through technological bottlenecks in the hydrogen energy industry, and strengthen the stability and competitiveness of the industrial and supply chains.

[0003] Compared to hybrid electric locomotives, hydrogen fuel cell locomotives offer advantages such as low noise and zero carbon emissions. However, hydrogen storage is crucial for the entire vehicle. The volumetric hydrogen storage density of gaseous hydrogen storage at 35 MPa is too low to meet the locomotive's range requirements. Unlike automobiles, locomotives are less sensitive to weight but require higher volumetric hydrogen storage density. Solid-state hydrogen storage systems can achieve volumetric hydrogen storage densities of up to (80–110) kg / m³. 3 With a relatively low mass hydrogen storage density (1.2–7.6 wt%), solid-state hydrogen storage systems are well-suited for use in locomotives.

[0004] It is evident that the current application of hydrogen fuel cell locomotives still has room for improvement. Optimization is needed to increase hydrogen storage volume density and enhance the locomotive's range when put into operation. Simultaneously, the heat dissipation requirements of hydrogen fuel cell locomotives during operation should be met to ensure stable start-up and operation. Therefore, a more reasonable technical solution is needed to address the technical problems existing in the current technology. Utility Model Content

[0005] To overcome at least one of the aforementioned defects, this utility model proposes a locomotive hydrogen power module that adopts a gas-solid composite hydrogen storage system, which solves the problem of hydrogen storage for the whole vehicle and the problem of hydrogen supply and heat dissipation during locomotive operation, thus ensuring the stable operation of the locomotive.

[0006] To achieve the above objectives, the hydrogen power module disclosed in this utility model can adopt the following technical solution:

[0007] A hydrogen power module for a vehicle includes a mounting body on which a fuel cell module, a heat dissipation module, and a composite hydrogen storage module are mounted. The composite hydrogen storage module works in conjunction with the fuel cell module to supply hydrogen to the fuel cell module. The composite hydrogen storage module includes several gaseous hydrogen storage cylinders and several solid hydrogen storage units. The gaseous hydrogen storage cylinders and solid hydrogen storage units supply hydrogen to the fuel cell module simultaneously or selectively. The heat dissipation module works in conjunction with the fuel cell module to dissipate heat from the fuel cell module.

[0008] The aforementioned hydrogen power module for locomotives uses a composite hydrogen storage module to store both gaseous and solid hydrogen, providing hydrogen energy flexibly to the fuel cell module and thus meeting the range requirements of hydrogen-powered locomotives. At the same time, a heat dissipation module cools the fuel cell module, reducing its temperature and preventing it from overheating.

[0009] Furthermore, the structure of the mounting body can be constructed in various forms and is not limited to a single one. Here, we optimize and propose one feasible option: the mounting body includes a power generation module frame, which includes a battery cavity and a heat dissipation cavity. The battery cavity is used to install the fuel cell module, and the heat dissipation cavity is located above the battery cavity and is used to install a heat dissipation module. The heat dissipation cavity is connected to the battery cavity and dissipates heat from the battery cavity to the outside. When adopting the above scheme, the power generation module frame includes a steel frame.

[0010] Furthermore, the structure of the mounting body is also used to house the composite hydrogen storage module. Here, an optimization is proposed, and one feasible option is suggested: the mounting body includes a hydrogen storage frame, which comprises several layers of hydrogen storage spaces arranged longitudinally, including several gaseous hydrogen storage spaces and several solid hydrogen storage spaces. When adopting the above scheme, the hydrogen storage frame comprises a steel frame.

[0011] Furthermore, the hydrogen storage scheme that can be adopted by the composite hydrogen storage module is not limited to a single one. Here, we optimize and propose one feasible option: a gaseous hydrogen storage cylinder is set in the gaseous hydrogen storage space, and several solid hydrogen storage units are set in the solid hydrogen storage space. The gaseous hydrogen storage cylinder and the solid hydrogen storage units are connected to the fuel cell module and supplied with hydrogen through a quick-connect interface. When adopting the above scheme, the gaseous hydrogen storage cylinder and the solid hydrogen storage units are placed layer by layer.

[0012] Furthermore, when supplying hydrogen to the fuel cell, the hydrogen storage and supply of the solid hydrogen storage unit are controlled separately. Here, we optimize and propose one feasible option: the solid hydrogen storage unit includes a hydrogen storage body, a hydrogen storage alloy is installed inside the hydrogen storage body, and the hydrogen storage body is equipped with quick-connect fittings for hydrogen inlet and outlet and quick-connect fittings for water inlet and outlet, which can facilitate the replacement and maintenance of individual solid hydrogen storage modules.

[0013] Furthermore, to facilitate inspection and maintenance, the hydrogen storage rack is optimized. One feasible option is to install an inspection door on the hydrogen storage rack to open or close the hydrogen storage space. When using this solution, the inspection door can be an outward-opening door.

[0014] Furthermore, solid-state hydrogen storage units can be installed on the hydrogen storage rack from multiple directions. Here, we propose one feasible option: the hydrogen storage space extends from the front to the rear of the hydrogen storage rack, and inspection doors are provided on both the front and rear sides of the rack. With this solution, the solid-state hydrogen storage units are symmetrically arranged and can be inspected and maintained through two inspection doors.

[0015] Furthermore, heat dissipation modules come in various forms, and their structure is not limited to a single type. Here, we optimize and propose one feasible option: the heat dissipation module includes a cooling fan and an intake air filter. When adopting the above solution, the intake air filter includes an intake air filter screen.

[0016] Furthermore, during heat dissipation, external air is introduced into the fuel cell module to remove the heat from the fuel cell module. Specifically, an optimization is proposed here, and one feasible option is: an air inlet is provided on the main body facing the fuel cell module, and the air inlet filter is located at the air inlet.

[0017] Furthermore, outward-opening doors are provided on the mounting frame for the fuel cell module and the heat dissipation module.

[0018] Compared with the prior art, some of the beneficial effects of the technical solution disclosed in this utility model include:

[0019] This invention improves the structure of the hydrogen power module by using a composite hydrogen storage module for gaseous and solid hydrogen storage and to supply hydrogen to the fuel cell. This can increase the hydrogen storage volume density, improve the vehicle's range, and also solve the problem of insufficient heat dissipation from the fuel cell when it is not fully started, thus preventing hydrogen release.

The composite hydrogen storage module includes several gaseous hydrogen storage cylinders 3 and several solid hydrogen storage units 4. The gaseous hydrogen storage cylinders 3 and the solid hydrogen storage units 4 can supply hydrogen to the fuel cell module 103 simultaneously or selectively. The heat dissipation module works in conjunction with the fuel cell module 103 to dissipate heat from the fuel cell module 103.

[0031] The locomotive hydrogen power module disclosed in this embodiment stores gaseous and solid hydrogen through a composite hydrogen storage module, which flexibly provides hydrogen energy to the fuel cell module 103 to meet the range requirements of hydrogen-powered locomotives; at the same time, a heat dissipation module dissipates heat from the fuel cell module 103 to reduce its temperature and prevent it from overheating.

[0032] The structure of the mounting body can be constructed in various forms and is not limited to a single one. This embodiment optimizes and adopts one feasible option: the mounting body includes a power generation module frame 1, which includes a battery cavity 101 and a heat dissipation cavity 102. The battery cavity 101 is used to install the fuel cell module 103, and the heat dissipation cavity 102 is located above the battery cavity 101 and is used to install a heat dissipation module. The heat dissipation cavity 102 is connected to the battery cavity 101 and dissipates the heat inside the battery cavity 101 to the outside. When adopting the above scheme, the power generation module frame 1 includes a steel frame.

[0033] The structure of the mounting body is also used to house the composite hydrogen storage module. This embodiment optimizes and adopts one feasible option: the mounting body includes a hydrogen storage frame 2, which includes several layers of hydrogen storage space arranged longitudinally, including several gaseous hydrogen storage spaces and several solid hydrogen storage spaces. When adopting the above scheme, the hydrogen storage frame 2 includes a steel frame.

[0034] The hydrogen storage scheme that can be used in the composite hydrogen storage module is not limited to a single one. This embodiment optimizes and adopts one feasible option: a gaseous hydrogen storage cylinder 3 is set in the gaseous hydrogen storage space, and several solid hydrogen storage units 4 are set in the solid hydrogen storage space. The gaseous hydrogen storage cylinder 3 and the solid hydrogen storage units 4 are connected to the fuel cell module 103 and supplied with hydrogen through a quick-connect interface. When the above scheme is adopted, the gaseous hydrogen storage cylinder 3 and the solid hydrogen storage units 4 are placed layer by layer.

[0035] When supplying hydrogen to the fuel cell, the hydrogen storage and supply of the solid hydrogen storage unit 4 are controlled separately. This embodiment optimizes and adopts one of the feasible options: the solid hydrogen storage unit 4 includes a hydrogen storage body, a hydrogen storage alloy is provided inside the hydrogen storage body, and the hydrogen storage body is provided with a quick-connect connector 401 for hydrogen inlet and outlet and a quick-connect connector 402 for water inlet and outlet, which can facilitate the replacement and maintenance of individual solid hydrogen storage modules.

[0036] To facilitate inspection and maintenance, the hydrogen storage rack 2 is optimized. This embodiment employs one feasible option: the hydrogen storage rack 2 is equipped with an inspection door for opening or closing the hydrogen storage space. When using the above solution, the inspection door can be an outward-opening door.

[0037] Solid hydrogen storage units 4 can be arranged on the hydrogen storage rack 2 from multiple directions. This embodiment optimizes the design and adopts one feasible option: the hydrogen storage space extends from the front to the rear of the hydrogen storage rack 2, and inspection doors are provided on both the front and rear sides of the hydrogen storage rack 2. With the above solution, the solid hydrogen storage units 4 are symmetrically arranged and can be inspected and maintained through two inspection doors.

[0038] Heat dissipation modules come in various forms, and their structure is not limited to a single type. This embodiment optimizes and adopts one feasible option: the heat dissipation module includes a cooling fan and an intake air filter. When using the above solution, the intake air filter includes an intake air filter screen.

[0039] During heat dissipation, external air is introduced into the fuel cell module 103 to remove the heat from the fuel cell module. Specifically, this embodiment optimizes and adopts one feasible option: an air inlet is provided on the main body facing the fuel cell module 103, and the air inlet filter is provided at the air inlet.

[0040] Outward-opening doors are provided on the mounting frame for the fuel cell module 103 and the heat dissipation module.

[0041] The hydrogen power module disclosed in this embodiment operates on the following principle:

[0042] The fuel cell system and heat dissipation system, piping accessories, etc. are respectively installed in the battery chamber 101 and the heat dissipation chamber 102. The fuel cell system is located below the heat dissipation module. Air enters the battery chamber 101 after being filtered by the filters on both sides of the side wall of the power generation module frame 1, and then enters the fuel cell system through the air filter built into the fuel cell system.

[0043] The hydrogen supply of the fuel cell system is mainly achieved through a gas-solid hybrid hydrogen storage module. This module can operate independently or simultaneously, and its hydrogen supply principle is as follows: Figure 4 As shown.

[0044] The switching between solid-state hydrogen storage and gaseous hydrogen storage is mainly achieved through quick-connect couplings placed before the solid-state hydrogen storage.

[0045] When gaseous hydrogen storage is required to operate independently during hydrogen addition and supply, the quick-connect fitting before solid hydrogen storage should be disconnected.

[0046] When solid hydrogen storage needs to operate independently, the quick-connect fitting before solid hydrogen storage is turned on, while the manual switches on the three sets of cylinder valves of the gaseous hydrogen storage cylinder are turned off.

[0047] When solid-state hydrogen storage and gaseous hydrogen storage are required to work simultaneously, the quick-connect fitting before solid-state hydrogen storage is connected, and the manual switches on the three sets of cylinder valves of the gaseous hydrogen storage cylinder are opened at the same time.

[0048] The quick-connect coupling located in front of the fuel cell is used for two purposes: firstly, during maintenance of the fuel cell module 103; and secondly, when the system is shut down, disconnecting from the fuel cell system allows for the rapid release of hydrogen from the entire pipeline through the vent, ensuring safety.

[0049] The above are the embodiments listed in this example. However, this example is not limited to the optional embodiments described above. Those skilled in the art can arbitrarily combine the above methods to obtain other various embodiments. Anyone can derive other various forms of embodiments under the guidance of this example. The above specific embodiments should not be construed as limiting the scope of protection of this example. The scope of protection of this example should be defined in the claims.
