[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0035] Reference below Figures 1-8 A compact fuel cell combined heat and power system according to an embodiment of the present invention is described.

[0036] The compact fuel cell cogeneration system of the embodiment of the present invention includes 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, with partitions disposed within the container body 1 to divide the installation cavity into multiple functional compartments. The multiple functional compartments include an adjacent fuel cell compartment 11 and a hydrogen valve circuit compartment 12. The fuel cell module includes a fuel cell (not shown) and a hydrogen valve circuit system 32. Hydrogen enters the fuel cell compartment 11 through a pipeline from the hydrogen valve circuit compartment after undergoing multi-stage decompression. The fuel cell is disposed within the fuel cell compartment 11, and the hydrogen valve circuit system 32 is disposed within the hydrogen valve circuit compartment 12. The electrical module 4, plate exchange module, and heat dissipation module 5 are correspondingly disposed within the other functional compartments, and the plate exchange module and heat dissipation module 5 are connected in parallel to the fuel cell module. It is understood that the fuel cell and hydrogen valve circuit system 32 are disposed adjacent to each other.

[0038] The compact fuel cell cogeneration system of the present embodiment places the fuel cell compartment 11 and the hydrogen valve path compartment 12 adjacent to each other, allowing hydrogen to enter the fuel cell compartment 11 through a pipeline from the hydrogen valve path compartment. This significantly shortens the length of this hydrogen pipeline, and through the rational layout of the interior of the container body 1, reduces the overall volume of the container body 1. This helps to improve the compactness of the fuel cell cogeneration system layout.

[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, as 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, electrical module 4, plate exchange module and heat dissipation module.

[0042] Alternatively, 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 multiple 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 disposed in the battery compartment 13, and the electrical component 42 is disposed in the electrical compartment 14. It is understood that the battery 41 and the electrical component 42 are disposed in two adjacent functional compartments.

[0044] The compact fuel cell cogeneration system of this embodiment shortens the length of the electrical wiring harness connecting the electrical components 42 to the battery 41 by locating the battery compartment 13 and the electrical compartment 14 adjacent to each other. This reduces the space occupied by the wiring harness and its cost. Consequently, this fuel cell cogeneration system offers the advantages of further increased compactness and reduced equipment costs.

[0045] Optionally, a battery module is arranged inside the battery 41 to store the electricity generated by the fuel cell and provide electricity 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 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 utility model 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 in a one-to-one correspondence in a plurality of different electrical placement areas. Support is provided 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 convenience of installation 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. The relevant high and low voltage lines are all gathered in the electrical compartment 14; the electrical compartment 14 is connected to the battery 41 through the wiring harness channel.

[0049] Furthermore, the support member 425 can be a mounting bracket that is welded or screwed to the partition or the wall of the container body 1. The high-voltage control cabinet 421, low-voltage control, inverter 423, and electric exhaust fan 424 are retractably mounted on the mounting bracket. Thus, the compact fuel cell cogeneration system of this embodiment of the utility model further enhances the convenience of equipment installation and maintenance.

[0050] Optionally, the electric exhaust fan 424 is arranged 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. The multiple functional compartments also include a main heat dissipation compartment 15 and a plate heat exchanger compartment 17. The main heat dissipation compartment 15 is located adjacent to the fuel-electric compartment 11. The main heat exchanger 51 is located within the main heat dissipation compartment 15, and the plate heat exchanger module is located within the plate heat exchanger compartment 17. The main heat exchanger 51 is located near the wall of the container body 1. The fuel cell module is connected to the main heat exchanger 51 and the plate heat exchanger module via a first three-way valve 61 to form a main heat exchange circulation pipeline. It is understood that the main heat exchanger 51 is located adjacent to the fuel cell module.

[0053] The compact fuel cell cogeneration system of this embodiment of the utility model, by arranging the main heat dissipation compartment 15 adjacent to the fuel cell compartment 11, connects the fuel cell module to the main heat exchanger 51 and the plate heat exchange module via the first three-way valve 61 to form a main heat exchange circulation pipeline. This shortens 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 its overall compactness and reduces equipment costs.

[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. 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 need for heating, 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 achieve urban heating scene utilization. When there is no need for heating, 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. The multiple functional compartments also include an auxiliary bulk compartment 16. The auxiliary heat exchanger 52 is disposed in the auxiliary bulk compartment 16. The auxiliary heat exchanger 52 is disposed adjacent to the battery 41 and is disposed near the side wall of the container body 1. It is understood that the auxiliary heat exchanger 52 is disposed adjacent to the battery 41.

[0056] The compact fuel cell cogeneration system of the present invention reduces the length of wiring harnesses and piping in this area by placing the auxiliary heat exchanger 52 adjacent to the battery compartment 13. This further enhances the overall compactness of the fuel cell cogeneration system and reduces equipment costs.

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

[0058] In the compact fuel cell cogeneration system of this embodiment, the coolant inside the electrical compartment 14 and the battery compartment 13 (the fuel cell system's BOP components) is connected to the auxiliary heat exchanger 52 and the plate exchange module via a second three-way valve 62, forming an auxiliary heat exchange circulation circuit. The BOP components are connected to the auxiliary heat exchanger 52 and the plate exchange module via the second three-way valve 62, forming a main heat exchange circulation circuit. The second three-way valve 62 can be used to control the connection between at least one of the auxiliary heat exchanger 52 and the plate exchange module and the BOP component's cooling channel. For example, when heating is needed, the plate exchange module can be connected to the BOP component, cooling the fuel cell interior with cooling water. The heated water after heat exchange can then be discharged for use in urban heating scenarios. When heating is not needed, the auxiliary heat exchanger 52 can be used to cool the BOP component to prevent overheating. If the internal temperature of the BOP component is too high, the plate exchange module and the auxiliary heat exchanger 52 can be activated simultaneously to cool the coolant.

[0059] Furthermore, an auxiliary heat exchange circulation pipeline is provided with an auxiliary heat dissipation 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 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 completing heat exchange.

[0061] like Figure 2 、 Figure 6 and Figure 7 As shown, the auxiliary bulk compartment 16 is arranged adjacent to the fuel and power compartment 11. This further reduces the cost of the heat exchange pipeline of the combined heat and power device.

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

[0063] The compact fuel cell cogeneration system of the embodiment of the utility model 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, avoiding 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 its width direction. 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 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 the 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 dispersion compartment 16, the second upper chamber sub-chamber forms an electrical compartment 14, and 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 this embodiment of the utility model is constructed by arranging 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 within the installation cavity to form a fuel cell 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 a simple structure and a rational layout. Furthermore, locating the fuel cell compartment 11 and the hydrogen valve circuit compartment 12 on the lower level further reduces the difficulty of installation and maintenance.

[0066] The auxiliary bulk compartment 16 and the battery compartment 13 can be the same space, and no partition is provided 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 within the first lower chamber. Hydrogen enters the fuel-electric compartment 11 via a pipeline from the hydrogen valve circuit compartment, significantly reducing its length. The main heat dissipation compartment 15, located in the second layer above the two, is connected to the fuel-electric compartment 11 via a pipeline for heat exchange, significantly reducing its length. The auxiliary cooling compartment 16 and the battery compartment 13 are arranged side by side on the first layer, with the electrical compartment 14 located in the second layer above them. The electrical wiring harness between the electrical compartment 14 and the battery compartment 13 is significantly shortened. The fuel-electric compartment 11 and the auxiliary cooling fan compartment are connected via a pipeline for heat exchange, significantly reducing their length. The plate exchange compartment 17, the largest in volume, is located separately in the third chamber and is connected to the fuel-electric compartment 11 via a pipeline for heat exchange, significantly reducing its length.

[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 bulk compartment 16 in sequence and extends to the outside of the container body 1.

[0069] Specifically, the fuel cell contains a coolant for cooling it. This coolant flows through the main circulation outlet and the main circulation electronic three-way valve (first three-way valve 61), which controls its flow rate to the main heat exchanger 51 and the plate heat exchanger's main circulation. The coolant flowing to the main heat exchanger 51 passes through the main radiator inlet and enters the main radiator for heat dissipation. After being cooled, the coolant passes through the main circulation outlet of the main heat exchanger 51. The coolant flowing to the plate heat exchanger passes through the plate heat exchanger inlet and enters the plate heat exchanger's main circulation for heat dissipation. After being cooled, the coolant passes through the plate heat exchanger's main circulation outlet, flows through the three-way valve to receive water from the main radiator expansion tank, flows through the first three-way valve 61 of the main heat exchange circulation pipeline, merges with the return water from the main radiator's main circulation outlet, and then passes through the main circulation inlet of the fuel cell. It is then pressurized by the electronic water pump within 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 and then passes through the auxiliary circulation second three-way valve 62, which controls its flow to the auxiliary heat exchanger 52 and the plate heat exchanger's auxiliary circulation. The coolant entering the auxiliary heat exchanger 52 is cooled, then flows out of the auxiliary heat exchanger 52 and passes through the auxiliary circulation second three-way valve 62. The coolant flowing to the plate heat exchanger passes through the plate heat exchanger inlet and enters the plate heat exchanger's auxiliary circulation for heat dissipation. After cooling, the coolant passes through the plate heat exchanger's main circulation outlet, receives water from the auxiliary expansion tank outlet, flows through the auxiliary circulation second three-way valve 62, merges with the return water from the auxiliary heat exchanger outlet, and is pressurized by the auxiliary electronic water pump. Together, they pass through the auxiliary circulation inlet of the fuel cell system's BOP components and enter the fuel cell system's BOP components for cooling.
