[0025] It should also be mentioned that in some alternative implementations, the functions / actions mentioned may occur in an order different from that indicated in the accompanying drawings. For example, depending on the functions / actions involved, two successive figures shown may actually be executed substantially simultaneously or sometimes in the reverse order.

[0026] To facilitate the understanding of the embodiments of the present invention, the implementation process of the present invention will be elaborated in detail through several specific embodiments below.

[0027] The first embodiment of the present invention provides a hydrogen refueling station heating system, which includes: a liquid hydrogen pipeline 111 for supplying liquid hydrogen; a combustion gasification device 22 attached to the liquid hydrogen pipeline 111 for performing heat exchange with the liquid hydrogen pipeline 111 to gasify the liquid hydrogen in the liquid hydrogen pipeline 111; and a hydrogen ignition device 24 for introducing and burning the gaseous hydrogen overflowing due to evaporation to provide heat for heat exchange between the combustion gasification device 22 and the liquid hydrogen pipeline 111.

[0028] In this regard, the hydrogen evaporated from the liquid hydrogen is ignited by the hydrogen ignition device 24 to heat the combustion gasification device 22, so that the combustion gasification device 22 can heat the liquid hydrogen pipeline 111 through heat exchange with the liquid hydrogen pipeline 111, thereby realizing the gasification of liquid hydrogen. That is: the hydrogen evaporated from the liquid hydrogen can be utilized to meet the endothermic demand for liquid hydrogen gasification. Moreover, it will not cause additional energy consumption, nor will it lead to additional cost losses and environmental pollution.

[0029] Specifically, the first embodiment of the present invention provides a hydrogen refueling station heating system, which includes: a liquid hydrogen pipeline 111, a combustion gasification device 22, and a hydrogen ignition device 24. The liquid hydrogen pipeline 111 is used to supply liquid hydrogen; the combustion gasification device 22 is attached to the liquid hydrogen pipeline 111, and the combustion gasification device 22 is used to perform heat exchange with the liquid hydrogen pipeline 111 to gasify the liquid hydrogen in the liquid hydrogen pipeline 111; the hydrogen ignition device 24 is used to introduce and burn the gaseous hydrogen overflowing due to evaporation to heat the combustion gasification device 22, thereby providing heat for heat exchange between the combustion gasification device 22 and the liquid hydrogen pipeline 111.

[0030] Among them, gaseous hydrogen is gaseous hydrogen, and liquid hydrogen and liquid hydrogen are liquids obtained by cooling hydrogen.

[0031] Certainly, in this embodiment, a part of the combustion gasification device 22 is located in the combustion area of the hydrogen ignition device 24 for the hydrogen ignition device 24 to heat the combustion gasification device 22.

[0032] Therefore, only by igniting the hydrogen evaporated from the liquid hydrogen through the hydrogen ignition device 24 to heat the combustion gasification device 22, so that the combustion gasification device 22 can heat the liquid hydrogen pipeline 111 through heat exchange with the liquid hydrogen pipeline 111, the gasification of liquid hydrogen can be realized. Of course, it will not cause additional energy consumption, nor will it lead to additional cost losses and environmental pollution.

[0033] In another embodiment, for the combustion gasification device 22, it includes: a combustion medium pipeline 221. In this embodiment, a part of the combustion medium pipeline 221, i.e., the combustion medium pipeline 221, is wound around the outer surface of the liquid hydrogen pipeline 111, and another part of the combustion medium pipeline 221 is located within the combustion area of the hydrogen ignition device 24. Of course, a heat exchange medium flows inside the combustion medium pipeline 221. When this other part of the combustion medium pipeline 221 is heated by the hydrogen ignition device 24, through the flow of the heat exchange medium, this part of the combustion gasification device 22 can exchange heat with the liquid hydrogen pipeline 111 to heat the liquid hydrogen pipeline 111, thereby realizing the gasification of liquid hydrogen.

[0034] Therefore, only by using the hydrogen ignition device 24 to ignite the hydrogen evaporated from the liquid hydrogen to heat the combustion medium pipeline 221, so that the combustion medium pipeline 221 wound around the liquid hydrogen pipeline 111 exchanges heat with the liquid hydrogen pipeline 111 to heat the liquid hydrogen pipeline 111, the gasification of liquid hydrogen can be realized. Of course, it will not cause additional energy consumption, nor will it lead to additional cost losses and environmental pollution.

[0035] Of course, in this embodiment, for the hydrogen ignition device 24, it includes: a burner 21 and an operation room heat exchanger 23. Among them, the burner 21 is used to ignite the introduced gaseous hydrogen overflowing due to evaporation to heat the combustion medium pipeline 221; and the operation room heat exchanger 23 is connected to the operation room heat exchange pipeline 311, and the operation room heat exchanger 23 is located within the combustion area of the burner 21 for the operation room heat exchange pipeline 311 to obtain heat. Among them, the operation room heat exchanger 23 will be described in detail later and will not be elaborated here. Thus, through the burner 21, the combustion of the evaporated gaseous hydrogen can be realized to utilize the evaporated gaseous hydrogen.

[0036] Of course, to further enhance the gasification effect of the liquid hydrogen in the liquid hydrogen pipeline 111, in another embodiment, the following settings are made:

[0037] The hydrogen filling station heating system further includes: a heat conduction medium pipeline group 30. Among them, the heat conduction medium pipeline group 30 is wound around the outer surface of the liquid hydrogen pipeline 111, and the heat conduction medium pipeline group 30 is used to exchange heat with the liquid hydrogen pipeline 111. Of course, a heat conduction medium to be cooled flows inside the heat conduction medium pipeline group 30, and the temperature of the heat conduction medium is higher than the temperature of the liquid hydrogen in the liquid hydrogen pipeline 111.

[0038] Of course, in this embodiment, the heat conduction medium pipeline group 30 is connected to the equipment that generates the heat conduction medium to be cooled during operation.

[0039] In this embodiment, the heat-conducting medium pipeline group 30 is connected to the heat-conducting medium to be cooled, and moreover, the temperature of the heat-conducting medium is higher than the temperature of the liquid hydrogen in the liquid hydrogen pipeline 111. Therefore, in this embodiment, heat exchange can be carried out between the heat-conducting medium pipeline group 30 and the liquid hydrogen pipeline 111, so as to further increase the gasification rate of the liquid hydrogen in the liquid hydrogen pipeline 111. Of course, the liquid hydrogen pipeline 111 can also be used as a cold source to cool the heat-conducting medium pipeline group 30, realizing the mutual use of resources; in addition, heat exchange between multiple energy sources and the liquid hydrogen pipeline 111 can also be realized.

[0040] For the heat-conducting medium pipeline group 30, in another embodiment, it at least includes: an initial gasification pipeline 31 and a completed gasification pipeline 32, and moreover, the initial gasification pipeline 31 and the completed gasification pipeline 32 are arranged in sequence on the liquid hydrogen pipeline 111 along the flowing direction of the liquid hydrogen.

[0041] Among them, the number of the initial gasification pipelines 31 is set to one or more. According to Figure 1 As shown, one initial gasification pipeline 31 is provided in this embodiment.

[0042] In this embodiment, the initial gasification pipeline 31 is used to carry out heat exchange with the liquid hydrogen in the liquid hydrogen pipeline 111, so as to initially heat and gasify the liquid hydrogen in the liquid hydrogen pipeline 111, cool the medium in the initial gasification pipeline 31, and obtain a mixture of liquid hydrogen and gaseous hydrogen in the liquid hydrogen pipeline 111.

[0043] For example: the initial gasification pipeline 31 includes but is not limited to one or both of the following: a hydrogen filling machine pipeline and a 70 MPa operation room heat exchange pipeline 311.

[0044] Specifically, the number of the hydrogen filling machine pipelines is set to one or more, and moreover, both ends of each hydrogen filling machine pipeline are connected to the corresponding hydrogen filling machine gaseous hydrogen input end and gaseous hydrogen output end to transmit the gaseous hydrogen compressed by the hydrogen filling machine.

[0045] The number of the operation room heat exchange pipelines 311 is set to one or more, and moreover, both ends of each operation room heat exchange pipeline 311 are connected to the input end and output end of the corresponding operation room heat exchanger 23 to transmit the operation room heat-conducting medium output by the operation room heat exchanger 23.

[0046] Of course, in this embodiment, the type, model, and number of the initial gasification pipeline 31 are not limited, as long as it meets the requirements of this embodiment.

[0047] According to Figure 1As shown, in this embodiment, two hydrogenation machine pipelines are provided, namely, a 35 MPa hydrogenation machine pipeline 313 and a 70 MPa hydrogenation machine pipeline 312, and an operation room heat exchange pipeline 311.

[0048] Furthermore, in this embodiment, the number of the above-mentioned gasification completion pipelines 32 is set to one or more, according to Figure 1 As shown, in this embodiment, a gasification completion pipeline 32 is provided.

[0049] In this embodiment, the gasification completion pipeline 32 is used to completely gasify the mixture of liquid hydrogen and gaseous hydrogen obtained by the initial heating and gasification in the initial gasification pipeline 31 .

[0050] For example, the gasification completion pipeline 32 includes one or both of the following: a heat pump pipeline 321 and a solar thermal generator pipeline 322. Further optimized, the gasification completion pipeline 32 also includes the aforementioned combustion medium pipeline 221. Of course, in this embodiment, the combustion medium pipeline 221 is also included in the aforementioned initial gasification pipeline 31, or the combustion medium pipeline 221 is included in both the aforementioned initial gasification pipeline 31 and the gasification completion pipeline 32.

[0051] Specifically, the number of the heat pump pipes 321 is set to one or more, and each heat pump pipe 321 is connected to a heat pump. In addition, a heat pump heat transfer medium flows through the heat pump pipe 321, thereby performing heat exchange with the liquid hydrogen pipe 111; of course, the temperature of the heat pump heat transfer medium is higher than the temperature of the liquid hydrogen pipe 111.

[0052] The number of the photothermal pipes 322 is set to one or more, and each of the photothermal pipes 322 is connected to the same photothermal pipe or different photothermal pipes, and each photothermal pipe 322 performs heat exchange with the liquid hydrogen pipe 111 based on the heat received from the photothermal pipe.

[0053] Furthermore, in this embodiment, heat dissipation fins are distributed on the peripheries of the heat pump pipe 321 and the photothermal pipe 322 .

[0054] Of course, in the present application, heat dissipation fins may be distributed on the outer surface of the pipes involved. With the help of the heat dissipation fins, the efficiency of heat exchange can be improved, thereby helping to increase the gasification rate of liquid hydrogen in the liquid hydrogen pipe 111.

[0055] Of course, in this embodiment, the heat transfer medium pipeline group 30 may also only include: any one of the initial gasification pipeline 31 and the gasification completion pipeline 32. Moreover, in this case, there is no specific limitation on the specific number of the initial gasification pipeline 31 and the specific number of the gasification completion pipeline 32, as long as they meet the requirements of this embodiment.

[0056] For example, when the heat-conducting medium pipeline group 30 only includes the initial gasification pipelines 31, a plurality of the initial gasification pipelines 31 can be arranged in sequence on the liquid hydrogen pipeline 111 along the flowing direction of liquid hydrogen. Thus, the liquid hydrogen in the liquid hydrogen pipeline 111 can be gradually gasified through these initial gasification pipelines 31.

[0057] When the heat-conducting medium pipeline group 30 only includes the gasification-completed pipelines 32, a plurality of the gasification-completed pipelines 32 can be arranged in sequence on the liquid hydrogen pipeline 111 along the flowing direction of liquid hydrogen. Thus, the liquid hydrogen in the liquid hydrogen pipeline 111 can be gradually gasified through these gasification-completed pipelines 32.

[0058] Certainly, in this embodiment, it further includes: a controller. Wherein, the number of the controllers corresponds to the heat pump, the solar heat collector, and the operation room heat exchanger 23 one by one. Moreover, the controller controls the opening and closing of the corresponding heat pump, solar heat collector, and operation room heat exchanger 23 by performing information interaction with the corresponding heat pump, solar heat collector, and operation room heat exchanger 23. Thus, by respectively controlling the opening and closing of the corresponding heat pump, solar heat collector, and operation room heat exchanger 23 through each controller, it helps to avoid information interference of control devices and ensures the smooth implementation of control actions.

[0059] Certainly, in another embodiment, the opening and closing of the heat pump, solar heat collector, and operation room heat exchanger 23 can also be respectively controlled only by one controller.

[0060] Certainly, in another embodiment, control valves can also be provided. Wherein, the number of the control valves is set to be multiple, and the control valves are arranged in all the pipelines involved in this application. Moreover, the control valve controls the on-off of the pipeline where the control valve is installed. Certainly, the control valve can receive a user instruction to control the on-off of the corresponding pipeline. Regarding the source of the user instruction, it is not limited in this embodiment.

[0061] In this regard, in this embodiment, not only can the utilized gaseous hydrogen evaporated be realized to meet the heat absorption requirement for liquid hydrogen gasification and the heating of the operation room; moreover, multiple heat exchanges of multiple energy sources can be realized; and the multiple heat exchange device can realize heating and cooling of the operation room; certainly, the liquid hydrogen pipeline can also be used as a cold source to cool the gaseous hydrogen in the hydrogen filling machine pipeline. Moreover, the overall heat exchange utilization of the solar heat collector and the heat pump is also realized; thus, the use of traditional energy sources is reduced; of course, the utilization rate of renewable energy and clean energy is also increased and the overall efficiency is improved; and multi-mode application is realized.

[0062] Of course, in order to increase the vaporization rate of liquid hydrogen in the liquid hydrogen pipeline 111, in another embodiment, the liquid hydrogen pipeline 111 can also be arranged as follows to increase the contact area between the liquid hydrogen pipeline 111 and the pipeline that exchanges heat with the liquid hydrogen pipeline 111:

[0063] The liquid hydrogen pipeline 111 includes at least two installation pipelines. Among them, the installation pipeline is used to install the heat-conducting medium pipeline, and the number of the installation pipelines corresponds one-to-one to the number of pipeline units in the heat-conducting medium pipeline. Specifically, when the heat-conducting medium pipeline only includes: an initial vaporization pipeline 31 and a vaporization-completed pipeline 32, the liquid hydrogen pipeline 111 includes: an initial installation pipeline 11 for the initial vaporization pipeline 31 to wind around, and a vaporization-completed installation pipeline 12 for the vaporization-completed pipeline 32 to wind around.

[0064] Among them, the number of the initial installation pipelines 11 corresponds one-to-one to the number of the initial vaporization pipelines 31; moreover, the initial installation pipeline 11 at least includes two initial parallel branches 112, and at least one of the initial parallel branches 112 is for the operation room heat exchange pipeline 311 to wind around, and the remaining initial parallel branches 112 are for the hydrogen filling machine pipeline to wind around. For example, according to Figure 1 As shown, the initial installation pipeline 11 includes three initial parallel branches 112, so that the three initial parallel branches 112 in the initial installation pipeline 11 are arranged in a "day" shape. One of the initial parallel branches 112 is for the 35 MPa hydrogen filling machine pipeline 313 to wind around, one of the initial parallel branches 112 is for the 70 MPa hydrogen filling machine pipeline 312 to wind around, and one of the initial parallel branches 112 is for the operation room heat exchange pipeline 311 to wind around.

[0065] Therefore, when the liquid hydrogen is diverted to the three initial parallel branches 112, the liquid hydrogen in the initial parallel branches 112 wound by the hydrogen filling machine pipeline and the operation room heat exchange pipeline 311 can be heated respectively to increase the vaporization rate of the liquid hydrogen in the initial installation pipeline 11.

[0066] Of course, in another embodiment, at least one of the initial parallel branches 112 in the initial installation pipeline 11 is for the combustion medium pipeline 221 to wind around. Thus, in this embodiment, the combustion medium pipeline 221 can be used as a part of the initial vaporization pipeline 31 to heat the liquid hydrogen in the initial parallel branches 112 wound by the combustion medium pipeline 221, so as to increase the vaporization rate of the liquid hydrogen in the initial installation pipeline 11.

[0067] The number of the gasification completion installation pipelines 12 corresponds one-to-one to that of the gasification completion pipelines 32; moreover, the gasification completion installation pipeline 12 includes at least three completed parallel branches 113, and at least one of the completed parallel branches 113 is for the heat pump pipeline 321 to wind around, and at least one of the completed parallel branches 113 is for the solar thermal pipeline to wind around.

[0068] In addition, at least one of the completed parallel branches 113 in the gasification completion installation pipeline 12 is for the combustion medium pipeline 221 to wind around. Thus, in this embodiment, the combustion medium pipeline 221 can be used as a part of the gasification completion pipeline 32 to heat the mixture of gaseous hydrogen and liquid hydrogen flowing out of the initial installation pipeline 11 so as to continuously gasify the mixture.

[0069] Such as: according to Figure 1 As shown, the gasification completion installation pipeline 12 includes three completed parallel branches 113, so that the three completed parallel branches 113 in the gasification completion installation pipeline 12 are arranged in a "day" shape. One of the completed parallel branches 113 is for the heat pump pipeline 321 to wind around, one of the completed parallel branches 113 is for the solar thermal pipeline to wind around, and one of the completed parallel branches 113 is for the combustion medium pipeline 221 to wind around.

[0070] Certainly, in this embodiment, the combustion medium pipeline 221 may be wound only on the initial installation pipeline 11, or only on the gasification completion installation pipeline 12, or may be wound on both the initial installation pipeline 11 and the gasification completion installation pipeline 12. In this embodiment, there is no limitation on this, as long as it meets the requirements of this embodiment.

[0071] Certainly, in this embodiment, after the liquid hydrogen in the liquid hydrogen pipeline 111 is completely gasified, it will enter the subsequent pressure regulating device through the pipeline, such as entering the power system of a fuel vehicle.

[0072] Certainly, in another embodiment, in order to improve the assembly rate of the hydrogen filling station heating system, each component is integrated into a module. Specifically, the hydrogen filling station heating system includes: a primary heat exchange module 41, a backend heat exchange module 42, and a hydrogen ignition heat exchange module 43. Specifically, in this embodiment, the above-mentioned initial installation pipeline 11, the operation room heat exchange pipeline 311 and the hydrogen filling machine pipeline are integrated into the housing of the primary heat exchange module 41. Specifically, according to Figures 1 to 2As shown, the above-mentioned initial installation pipeline 11, operation room heat exchange pipeline 311, 70 MPa hydrogen refueling machine pipeline 312, and 35 MPa hydrogen refueling machine pipeline 313 are integrated into the housing of the primary heat exchange module 41. Moreover, the above-mentioned gasification completion installation pipeline 12, heat pump pipeline 321, solar heater pipeline 322, and combustion medium pipeline 221 are integrated into the housing of the rear-end heat exchange module 42. In addition, the burner 21 and the operation room heat exchanger 23 are also integrated into the housing of the hydrogen ignition heat exchange module 43.

[0073] Of course, according to Figure 3 As shown, the primary heat exchange module 41, the rear-end heat exchange module 42, and the hydrogen ignition heat exchange module 43 can also be integrated into the same housing to form a hydrogen refueling station heating module 40.

[0074] In addition, in another embodiment, a fuel vehicle is also provided. The fuel vehicle includes: the hydrogen refueling station heating system provided in any of the above embodiments, a hydrogen collector, and an energy conversion device. Among them, the hydrogen collector is used to collect the hydrogen overflowing from the hydrogen storage tank, and moreover, the hydrogen collector is used to collect the gaseous hydrogen overflowing from the hydrogen storage tank and is connected to the hydrogen ignition device 24 to supply the collected gaseous hydrogen to the hydrogen ignition device 24.
