[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0035] In this application, the terms "installed", "set", "provided with", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, elements, or components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0036] In addition, the terms "first", "second", etc. are mainly used to distinguish different devices, elements or components (the specific types and structures may be the same or different), and are not used to indicate or imply the relative importance and quantity of the indicated devices, elements or components. Unless otherwise specified, "plurality" means two or more.
[0037] The technical solution of the present application will be further described below in conjunction with specific embodiments and drawings.
[0038] Please also read Figure 1 and Figure 2 In the first aspect, the embodiment of the present application discloses a hydrogen fuel cell system 1, which is arranged in a rail vehicle having a cab and a machine room that are adjacent and spaced apart. The hydrogen fuel cell system 1 includes a heat dissipation module 11, a hydrogen storage module 12, and a stack module 13 that are sequentially spaced apart along the length direction of the rail vehicle, and the hydrogen storage module 12 and the heat dissipation module 11 are both arranged at the top of the machine room, and the hydrogen storage module 12 and the heat dissipation module 11 are connected through a first pipe 14, and the stack module 13 is arranged at the top of the cab and the top of the machine room, and the stack module 13 and the hydrogen storage module 12 are connected through a second pipe 15.
[0039] It is understandable that the length of the mechanical room of the rail vehicle in the length direction of the rail vehicle is fixed, while the volume of the stack module 13, hydrogen storage module 12 and heat dissipation module 11 of the hydrogen fuel cell system 1 is fixed and large. If all of them are arranged on the top of the mechanical room, the intervals between the modules will be small, and even the modules will abut against each other, which will be inconvenient for the staff to install and maintain the hydrogen fuel cell system 1.
[0040] In order to solve this problem, in the embodiment of the present application, the stack module 13 is arranged on the top of the cab and the top of the machine room. In other words, part of the stack module 13 is arranged on the top of the cab, and another part is arranged on the top of the machine room, that is, the top of the cab and the top of the machine room simultaneously carry the stack module 13. By arranging the hydrogen storage module 12 and the heat dissipation module 11 on the top of the machine room, the interval between the hydrogen storage module 12 and the heat dissipation module 11 can be increased, and the interval between the stack module 13 and the hydrogen storage module 12 can be increased, providing sufficient operating space for the staff, facilitating the staff to install, inspect, repair and replace the three modules, etc., reducing the difficulty of installing and maintaining the hydrogen fuel cell system 1, and improving the efficiency of installation and maintenance. In addition, increasing the interval between the three modules can reduce the mutual influence between two adjacent modules, reduce the possibility of accidents in the hydrogen fuel cell system 1, and improve the safety of the hydrogen fuel cell system 1.
[0041] In some embodiments, the first pipe 14 is a rigid pipe.
[0042] Rigidity refers to the ability of an object to resist deformation, and a rigid pipe is a pipe with strong rigidity. For example, the first pipe 14 can be a stainless steel pipe or other rigid metal pipe, which is not limited here.
[0043] Setting the first pipeline 14 as a rigid pipeline can better withstand the pressure of hydrogen in the pipeline, reduce the risk of deformation or rupture of the first pipeline 14 due to external impact, and ensure the stability of the first pipeline 14. At the same time, the first pipeline 14 is a rigid pipeline, which can improve the sealing of the first pipeline 14 and reduce the possibility of hydrogen leakage.
[0044] In addition, it can be understood that the first pipe 14 is only located at the top of the mechanical room, so the first pipe 14 as a whole is only affected by the vibration frequency and amplitude of the mechanical room. Setting the first pipe 14 as a rigid pipe will not cause the first pipe 14 to be subjected to mutual tearing forces.
[0045] In some other embodiments, the first pipe 14 may also be a flexible pipe.
[0046] Please continue reading Figure 1 and Figure 2 In some embodiments, the second pipe 15 includes a first sub-pipe 151 and a second sub-pipe 152. The first sub-pipe 151 is located above the machine room, and the first sub-pipe 151 is connected to the hydrogen storage module 12. The second sub-pipe 152 is located above the position between the cab and the machine room, one end of the second sub-pipe 152 is connected to the first sub-pipe 151, and the other end is connected to the fuel cell module 13, and the second sub-pipe 152 is a flexible pipe.
[0047] Flexibility refers to the ability of an object to respond to deformation, that is, the object can deform to a certain extent without being easily damaged when subjected to external force. For example, the second sub-pipeline 152 can be made of rubber or plastic such as polyvinyl chloride, which is not limited here.
[0048] In this embodiment, the second pipe 15 is not only located above the machine room, but also located above the position between the cab and the machine room. Therefore, the second pipe 15 is not only affected by the vibration frequency of the machine room, but also by the vibration frequency of the cab. The vibration frequency of the machine room is generally different from that of the cab, and the amplitude of the cab is generally different from that of the machine room. Therefore, if the second pipe 15 is a rigid pipe and the second pipe 15 is affected by different vibration frequencies and different amplitudes at the same time, it may cause damage to the second pipe 15, thereby causing hydrogen leakage. In order to solve this problem, in this embodiment, the second sub-pipe 152 located above the position between the cab and the machine room is set as a flexible pipe, which can absorb and alleviate the impact caused by different amplitudes and different vibration frequencies, thereby preventing the second sub-pipe 152 from being damaged and improving the service life of the second sub-pipe 152.
[0049] In some other embodiments, the second pipeline 15 may be entirely located above the machinery room.
[0050] In some embodiments, the first sub-pipe 151 is a rigid pipe.
[0051] Exemplarily, the first sub-pipeline 151 may be a stainless steel pipe or other rigid metal pipe, which is not limited here.
[0052] Setting the first sub-pipeline 151 as a rigid pipe can better withstand the pressure of hydrogen in the pipe, reduce the risk of deformation or rupture of the first sub-pipeline 151 due to external impact, and ensure the stability of the first sub-pipeline 151. At the same time, the first sub-pipeline 151 is a rigid pipe, which can improve the sealing of the first sub-pipeline 151 and reduce the possibility of hydrogen leakage.
[0053] In addition, it can be understood that the first sub-pipe 151 is only located at the top of the mechanical room, so the first sub-pipe 151 is only affected by the vibration frequency and amplitude of the mechanical room. Setting the first sub-pipe 151 as a rigid pipe will not cause the first sub-pipe 151 to be subjected to mutual tearing forces.
[0054] In some other embodiments, the first sub-pipe 151 may also be a flexible pipe.
[0055] Please continue reading Figure 1 and Figure 2 In some more specific embodiments, the second pipe 15 also includes a third sub-pipe 153 located above the cab, one end of the third sub-pipe 153 is connected to an end of the second sub-pipe 152 away from the first sub-pipe 151 , and the other end is connected to the stack module 13 .
[0056] The third sub-pipeline 153 is provided above the cab to increase the length of the second pipe 15, thereby preventing the second pipe 15 from being continuously subjected to tension in the length direction of the second pipe 15, thereby preventing the second pipe 15 from being broken and causing hydrogen leakage.
[0057] In some other more specific embodiments, the end of the second sub-pipe 152 away from the first sub-pipe 151 may also be directly connected to the fuel cell module 13 .
[0058] In some more specific embodiments, the third sub-pipe 153 is a rigid pipe.
[0059] Since the third sub-duct 153 is located above the cab, the third sub-duct 153 is only affected by the vibration frequency and amplitude of the cab, so the third sub-duct 153 can also be a rigid duct.
[0060] In some other more specific implementations, the third sub-pipeline 153 may also be a flexible pipe.
[0061] Please refer again Figure 1In some embodiments, the hydrogen fuel cell system 1 further includes two baffles 16 , which are disposed at the top of the mechanical room and located on both sides of the hydrogen storage module 12 , and one end of the baffle 16 abuts against the stack module 13 , and the other end abuts against the heat dissipation module 11 .
[0062] In this embodiment, baffles 16 are respectively provided on both sides of the hydrogen storage module 12 to protect the hydrogen storage module 12. The two ends of the baffle 16 abut against the stack module 13 and the heat dissipation module 11 respectively, which can improve the stability of the hydrogen fuel cell system 1.
[0063] In some other embodiments, two ends of the baffle 16 may form gaps with the stack module 13 and the heat dissipation module 11 , respectively.
[0064] In some embodiments, the baffle 16 can be rotatably disposed at the top of the machine room and can be relatively opened or closed. It is understandable that when the baffle 16 is opened, it is convenient for the staff to enter the interval between the hydrogen storage module 12 and the heat dissipation module 11 and the interval between the stack module 13 and the hydrogen storage module 12, so as to facilitate the staff to install and maintain each module.
[0065] In some other embodiments, the baffle 16 may be fixedly mounted on the top of the machinery room.
[0066] Please continue reading Figure 1 In some embodiments, the hydrogen fuel cell system 1 further includes a first frame 171 , which is disposed on the top of the cab, and a portion of the stack module 13 located above the top of the cab is disposed on the first frame 171 .
[0067] The first frame 171 is disposed on the top of the cab and can provide support for the portion of the stack module 13 located above the top of the cab.
[0068] It can be understood that the first frame 171 is disposed on the top of the cab, and the vibration frequency of the first frame 171 is substantially the same as the vibration frequency of the cab, and the amplitude of the first frame 171 is substantially the same as the amplitude of the cab.
[0069] In some other embodiments, the portion of the stack module 13 located above the top of the cab may also be directly supported on the top of the cab.
[0070] Please continue reading Figure 1 In some more specific embodiments, the hydrogen fuel cell system 1 also includes a second frame 172, which is disposed on the top of the mechanical room. The portion of the stack module 13 located above the top of the mechanical room, the hydrogen storage module 12 and the heat dissipation module 11 are all disposed on the second frame 172.
[0071] Similarly, the second frame 172 is disposed on the top of the mechanical room and can provide support for the portion of the stack module 13 located above the top of the mechanical room, the hydrogen storage module 12 and the heat dissipation module 11 .
[0072] It is understandable that the second frame 172 is disposed on the top of the machine room, and the vibration frequency of the second frame 172 is substantially the same as the vibration frequency of the machine room, and the amplitude of the second frame 172 is substantially the same as the amplitude of the machine room.
[0073] In some other more specific embodiments, the portion of the stack module 13 located above the top of the machinery room, the hydrogen storage module 12 and the heat dissipation module 11 are all disposed on the top of the machinery room.
[0074] In a second aspect, an embodiment of the present application further discloses a rail vehicle (not shown in the figure), comprising the hydrogen fuel cell system 1 as described above.
[0075] The rail vehicle provided in this embodiment arranges the stack module 13 on the top of the cab and the top of the machinery room, which can increase the interval between the hydrogen storage module 12 and the heat dissipation module 11, and at the same time increase the interval between the stack module 13 and the hydrogen storage module 12, providing sufficient operating space for the staff, making it convenient for the staff to install, inspect, repair and replace the three modules, reducing the difficulty of installation and maintenance of the hydrogen fuel cell system 1, and improving the efficiency of installation and maintenance.
[0076] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
