[0036] The compact fuel cell cogeneration system according to the embodiment of the present invention comprises a container body 1 , a partition, a fuel cell module, an electrical module 4 , a plate exchange module (not shown) and a heat dissipation module 5 .

[0037] The container body 1 has an installation cavity, and a partition is arranged in the container body 1 to divide the installation cavity into multiple functional compartments, and the multiple functional compartments include adjacent fuel-electric compartments 11 and hydrogen valve circuit compartments 12; the fuel cell module includes a fuel cell (not shown) and a hydrogen valve circuit system 32, and hydrogen enters the fuel-electric compartment 11 after multiple stages of decompression from the hydrogen valve circuit compartment through a pipeline, and the fuel cell is arranged in the fuel-electric compartment 11, and the hydrogen valve circuit system 32 is arranged in the hydrogen valve circuit compartment 12; the electrical module 4, the plate exchange module and the heat dissipation module 5 are correspondingly arranged in other functional compartments, and the plate exchange module and the heat dissipation module 5 are connected in parallel with the fuel cell module. It can be understood that the fuel cell and the hydrogen valve circuit system 32 are arranged adjacent to each other.

[0038] The compact fuel cell cogeneration system of the embodiment of the present invention arranges the fuel-electric compartment 11 and the hydrogen valve path compartment 12 adjacently, so that hydrogen enters the fuel-electric compartment 11 from the hydrogen valve path compartment through a pipeline, thereby significantly shortening the length of the hydrogen pipeline, so as to reduce the overall volume of the container body 1 through a reasonable layout inside the container body 1. This helps to improve the compactness of the layout of the fuel cell cogeneration system.

[0039] Therefore, the compact fuel cell cogeneration system according to the embodiment of the present invention has the advantage of helping to improve the compactness of the internal layout.

[0040] Optionally, the plate exchange module is a plate heat exchanger.

[0041] Alternatively, if Figure 1 As shown, the compact fuel cell cogeneration system also includes a main control screen 7, which can display the status of various components of the fuel cell cogeneration system and perform real-time control. The main control screen is electrically connected to the fuel cell module, the electrical module 4, the plate exchange module and the heat dissipation module.

[0042] Optionally, the fuel cell may be fixed to the interior of the fuel cell compartment 11 via a fixing groove.

[0043] like Figure 1 , Figure 5 and Figure 7 As shown, the plurality of functional compartments further include an adjacent battery compartment 13 and an electrical compartment 14, the electrical module 4 includes a battery 41 and an electrical component 42, the battery 41 is arranged in the battery compartment 13, and the electrical component 42 is arranged in the electrical compartment 14. It can be understood that the battery 41 and the electrical component 42 are arranged in two adjacent functional compartments.

[0044] The compact fuel cell cogeneration system of the embodiment of the present invention shortens the length of the electrical harness used to connect the electrical element 42 to the battery 41 by arranging the battery compartment 13 and the electrical compartment 14 adjacent to each other. Therefore, the space occupied by the harness and the harness cost are reduced. As a result, the fuel cell cogeneration system has the advantages of further improving compactness and reducing equipment costs.

[0045] Optionally, a battery module is arranged inside the battery 41 to store the electric energy generated by the fuel cell and provide electric energy for startup in an off-grid situation.

[0046] like Figure 1 , Figure 5 and Figure 7As shown, the electrical components 42 include a high-voltage control cabinet 421, a low-voltage control cabinet 422, an inverter 423, an electrical exhaust fan 424 and a plurality of supports 425. The plurality of supports 425 are arranged in the electrical compartment 14 so as to divide the electrical compartment 14 into a plurality of electrical placement areas. The high-voltage control cabinet 421, the low-voltage control cabinet 422, the inverter 423 and the electrical exhaust fan 424 are arranged one by one in a plurality of different electrical placement areas. The fuel cell module is connected to the external power grid through the inverter 423, and the electrical exhaust fan 424 is arranged close to the wall of the container body 1.

[0047] The compact fuel cell cogeneration system of the embodiment of the present invention is provided with a plurality of support members 425 in the electrical compartment 14 so as to divide the electrical compartment 14 into a plurality of electrical placement areas, and the high-voltage control cabinet 421, the low-voltage control cabinet 422, the inverter 423 and the electrical exhaust fan 424 are arranged one by one in a plurality of different electrical placement areas. Support is formed for the corresponding components to avoid the problems of poor structural stability and poor installation and maintenance convenience caused by concentrated accumulation. Thus, the advantages of installation convenience and structural stability are improved. In addition, the electrical exhaust fan 424 is arranged close to the wall of the container body 1, thereby improving the efficiency of heat dissipation.

[0048] The electric energy generated by the fuel cell is inverted and boosted by the inverter 423 to be connected to the power grid, and the relevant high and low voltage lines are gathered in the electrical compartment 14; the electrical compartment 14 is connected to the battery 41 through a channel for the wiring harness.

[0049] Furthermore, the support member 425 may be a mounting frame, which is welded or screwed to the partition or the wall of the container body 1, and the high-voltage control cabinet 421, the low-voltage control, the inverter 423 and the electric exhaust fan 424 can be pulled out and arranged on the mounting frame. Thus, the compact fuel cell cogeneration system of the embodiment of the present invention further enhances the convenience of equipment installation and maintenance.

[0050] Optionally, the electric exhaust fan 424 is disposed close to the top wall of the container body 1 .

[0051] Optionally, the inverter 423 may be a DC / AC inverter.

[0052] like Figure 1 , Figure 2 , Figure 5 , Figure 7 and Figure 8As shown, the heat dissipation module 5 includes a main heat exchanger 51, and the multiple functional cabins also include a main heat dissipation compartment 15 and a plate exchange compartment 17. The main heat dissipation compartment 15 is arranged adjacent to the fuel-electric compartment 11, the main heat exchanger 51 is arranged in the main heat dissipation compartment 15, and the plate exchange module is arranged in the plate exchange compartment 17. The main heat exchanger 51 is arranged close to the wall of the container body 1, and the fuel cell module is connected to the main heat exchanger 51 and the plate exchange module through the first three-way valve 61 to form a main heat exchange circulation pipeline. It can be understood that the main heat exchanger 51 is arranged adjacent to the fuel cell module.

[0053] The compact fuel cell cogeneration system of the embodiment of the present invention arranges the main heat dissipation compartment 15 adjacent to the fuel-electric compartment 11, and the fuel cell module is connected to the main heat exchanger 51 and the plate exchange module through the first three-way valve 61 to form a main heat exchange circulation pipeline, thereby shortening the length of the pipeline connecting the main heat exchanger 51 and the fuel cell module. As a result, the fuel cell cogeneration system further improves the overall compactness and reduces the equipment cost.

[0054] In addition, the fuel cell module is connected to the main heat exchanger 51 and the plate exchange module through the first three-way valve 61 to form a main heat exchange circulation pipeline, and the first three-way valve 61 can be used to control at least one of the main heat exchanger 51 and the plate exchange module to be connected to the cooling channel of the fuel cell module. For example, when there is a heating demand, the plate exchange module can be connected to the fuel cell module, the inside of the fuel cell can be cooled by cooling water, and the hot water after heat exchange can be exported to realize the use of urban heating scenarios. When there is no heating demand, the fuel cell module can be cooled by the main heat exchanger 51 to avoid overheating inside the battery. When the internal temperature of the fuel cell is too high, the plate exchange module and the main heat exchanger 51 can be started at the same time to cool the coolant at the same time.

[0055] like Figure 2 , Figure 6 and Figure 7 As shown, the heat dissipation module 5 includes an auxiliary heat exchanger 52, and the plurality of functional compartments further include an auxiliary heat exchanger 52. The auxiliary heat exchanger 52 is disposed in the auxiliary heat exchanger 16, and the auxiliary heat exchanger 52 is disposed adjacent to the battery 41, and the auxiliary heat exchanger 52 is disposed adjacent to the side wall of the container body 1. It can be understood that the auxiliary heat exchanger 52 is disposed adjacent to the battery 41.

[0056] The compact fuel cell cogeneration system of the embodiment of the present invention can reduce the length of the wiring harness and pipeline of this part by arranging the auxiliary heat exchanger 52 adjacent to the battery compartment 13. Therefore, the fuel cell cogeneration system has the advantages of further improving the overall compactness and reducing the equipment cost.

[0057] like Figure 2As shown, the BOP components integrated in the fuel cell system are connected to the auxiliary heat exchanger 52 and the plate exchange module to form an auxiliary heat exchange circulation pipeline. The BOP components include the air compressor, air compressor controller, hydrogen pump controller, DCDC and other heat-generating components integrated in the fuel cell system.

[0058] The compact fuel cell cogeneration system of the embodiment of the present invention is connected to the auxiliary heat exchanger 52 and the plate exchange module through the second three-way valve 62 through the coolant inside the electrical compartment 14 and the battery compartment 13 (fuel cell system BOP component) to form an auxiliary heat exchange circulation pipeline arrangement. The BOP component is connected to the auxiliary heat exchanger 52 and the plate exchange module through the second three-way valve 62 to form a main heat exchange circulation pipeline. The second three-way valve 62 can be used to control at least one of the auxiliary heat exchanger 52 and the plate exchange module to be connected to the cooling channel of the BOP component. For example, when there is a heating demand, the plate exchange module can be connected to the BOP component, the fuel cell can be cooled by cooling water, and the hot water after heat exchange can be exported to realize the use of urban heating scenarios. When there is no heating demand, the BOP component can be cooled by the auxiliary heat exchanger 52 to avoid the problem of overheating inside the BOP component. When the internal temperature of the BOP component is too high, the plate exchange module and the auxiliary heat exchanger 52 can be started at the same time to cool the coolant.

[0059] Furthermore, an auxiliary heat exchange circulation pipeline is provided with an auxiliary diffuser electronic water pump to control the water in the auxiliary circulation pipeline of the fuel cell system and change the flow rate to the plate heat exchanger and the auxiliary diffuser heat exchanger respectively.

[0060] Furthermore, the first three-way valve 61 and the second three-way valve 62 are both electronic three-way valves, which control the incoming flow rate and output hot water for use in urban scenarios after heat exchange is completed.

[0061] like Figure 2 , Figure 6 and Figure 7 As shown, the auxiliary bulkhead compartment 16 is arranged adjacent to the fuel-electric compartment 11. Thus, the cost of the heat exchange pipeline of the combined heat and power generation device is further reduced.

[0062] The compact fuel cell cogeneration system of the embodiment of the present invention further includes a water replenishment tank, and water replenishment ports are provided in the main heat exchange circulation pipeline and the auxiliary heat exchange circulation pipeline. The water replenishment tank is connected to the main heat exchange circulation pipeline and the auxiliary heat exchange circulation pipeline through the water replenishment ports.

[0063] The compact fuel cell cogeneration system of the embodiment of the present invention can replenish the cooling water of the main heat exchange circulation pipeline and the auxiliary heat exchange circulation pipeline in time through the provided water replenishment tank to avoid the problem of internal liquid shortage, and can also increase the cooling speed through external water replenishment.

[0064] like Figures 1 to 8As shown, the partition includes a first vertical plate 21, a second vertical plate 22, a first horizontal plate 23, a second horizontal plate 24 and a longitudinal plate 25 arranged in the installation cavity. The first vertical plate 21 and the second vertical plate 22 are arranged in the installation cavity to divide the installation cavity into a first chamber, a second chamber and a third chamber arranged in sequence along the width direction thereof. The first horizontal plate 23 is arranged in the first chamber to divide the first chamber into a first upper chamber sub-chamber and a first lower chamber sub-chamber. The longitudinal plate 25 is arranged in the first lower chamber sub-chamber so as to divide the first upper chamber sub-chamber into a fuel-electric compartment 11 and a hydrogen valve path compartment 12. The first upper chamber sub-chamber is a main heat dissipation compartment 15. The second horizontal plate 24 is arranged in the second chamber to divide the second chamber into a second upper chamber sub-chamber and a second lower chamber sub-chamber. The second lower chamber sub-chamber forms an auxiliary heat dissipation compartment 16, and the second upper chamber sub-chamber forms an electrical compartment 14. The plate exchange module is arranged in the third chamber to form a plate exchange compartment 17. It can be understood that the auxiliary heat exchanger 52 is arranged in the second lower chamber sub-chamber, the electrical compartment 14 is arranged in the second upper chamber sub-chamber, and the plate heat exchanger module is arranged in the third chamber.

[0065] The compact fuel cell cogeneration system of the embodiment of the present invention is provided with a first vertical plate 21, a second vertical plate 22, a first horizontal plate 23, a second horizontal plate 24 and a longitudinal plate 25 in the installation cavity to form a fuel-electric compartment 11, a hydrogen valve circuit compartment 12, a main heat dissipation compartment 15, an auxiliary heat dissipation compartment 16, an electrical compartment 14, a battery compartment 13 and a plate exchange compartment 17. As a result, the fuel cell cogeneration system has the advantages of simple structure and reasonable layout. Furthermore, the fuel-electric compartment 11 and the hydrogen valve circuit compartment 12 are arranged in the lower layer, which can also reduce the difficulty of installation and maintenance.

[0066] The auxiliary bulkhead compartment 16 and the battery compartment 13 may be the same space, with no partition plate arranged in between.

[0067] For example, Figures 1 to 8 As shown, the fuel-electric compartment 11 and the hydrogen valve circuit compartment are arranged side by side in the first lower chamber sub-chamber, and hydrogen enters the fuel-electric compartment 11 from the hydrogen valve circuit compartment through a pipeline, and the length is significantly shortened. The main heat dissipation compartment 15 is located in the second layer above the two, and the coolant is connected to the fuel-electric compartment 11 through a pipeline for heat exchange, and the length is significantly shortened. The auxiliary heat dissipation compartment 16 and the battery compartment 13 are arranged side by side on the first layer, and the electrical compartment 14 is located on the second layer above the two. The length of the electrical harness between the electrical compartment 14 and the battery compartment 13 is significantly shortened; the fuel-electric compartment 11 and the auxiliary heat dissipation fan compartment are connected through a pipeline for heat exchange, and the length is significantly shortened. The plate exchange compartment 17 has the largest volume and is separately arranged in the third chamber. It is connected to the fuel-electric compartment 11 through a pipeline for heat exchange, and the length is significantly shortened.

[0068] like Figure 1 and Figure 6As shown, one end of the tail exhaust pipe 31 of the fuel cell module is connected to the fuel cell, and the other end of the tail exhaust pipe 31 passes through the fuel-electric compartment 11 and the auxiliary diffuser compartment 16 in sequence and extends to the outside of the container body 1.

[0069] Specifically, the fuel cell has a cooling liquid for cooling it, which passes through the main circulation water outlet and the electronic three-way valve (first three-way valve 61) of the main circulation to control the flow of the main circulation to the main heat exchanger 51 and the plate heat exchanger. The cooling liquid flowing to the main heat exchanger 51 passes through the main heat sink inlet and enters the main radiator for heat dissipation. After the cooling liquid is cooled, it passes through the main circulation outlet of the main heat exchanger 51; the cooling liquid flowing to the plate heat exchanger passes through the plate heat exchanger inlet and enters the main circulation of the plate heat exchanger for heat dissipation. After the cooling liquid is cooled, it passes through the main circulation outlet of the plate heat exchanger, flows through the three-way valve to receive water replenishment from the main heat sink expansion tank, flows through the first three-way valve 61 of the main heat exchange circulation pipeline, and merges with the return water from the main circulation outlet of the main radiator, and then passes through the main circulation water inlet of the fuel cell together, and is then pressurized by the electronic water pump inside the fuel cell system to cool the fuel cell.

[0070] The coolant used to cool the BOP components flows out through the auxiliary circulation outlet, passes through the second three-way valve 62 of the auxiliary circulation, and controls the flow rate of the auxiliary circulation to the auxiliary heat exchanger 52 and the plate heat exchanger. The coolant entering the auxiliary heat exchanger 52 is cooled, and flows out of the auxiliary heat exchanger 52 and passes through the second three-way valve 62 of the auxiliary circulation; the coolant flowing to the plate heat exchanger passes through the inlet of the plate heat exchanger and enters the auxiliary circulation of the plate heat exchanger for heat dissipation. After being cooled, the coolant passes through the outlet of the main circulation of the plate heat exchanger, receives water from the outlet of the auxiliary heat exchanger expansion tank, flows through the second three-way valve 62 of the auxiliary circulation, merges with the return water at the outlet of the auxiliary heat exchanger, is pressurized by the auxiliary heat exchanger electronic water pump, and passes through the auxiliary circulation inlet of the fuel cell system BOP components together, and enters the fuel cell system BOP components for cooling.
