[0039] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.
[0040] It should also be noted that this application uses an arrow labeled X to indicate the first direction X, and an arrow labeled Y to indicate the second direction Y. The first direction X can be the arrangement direction of the first power unit 2 and the second power unit 3, and the second direction Y can be the arrangement direction of the cooling unit 11 and the control unit 4. The first direction X and the second direction Y are introduced to more clearly illustrate the structural positional relationship of the components of the hydrogen production power supply. The first direction X and the second direction Y intersect, and further, the first direction X and the second direction Y are perpendicular.
[0041] In related technologies, hydrogen production power supplies convert alternating current (AC) to direct current (DC), generating a significant amount of heat during operation. This heat can reduce the efficiency of power units or even damage them. Therefore, cooling is necessary for the hydrogen production power supply. Two common cooling solutions are used: forced air cooling with fans and liquid cooling. As the scale of hydrogen production systems and the hydrogen production capacity per electrolyzer increase, the power requirements for the power supply also rise, rendering forced air cooling insufficient. Liquid cooling typically involves a separate heat exchanger, which is bulky and expensive. Furthermore, separate control systems for the hydrogen production power supply and the heat exchanger can lead to poor coordination and unclear responsibility during malfunctions, as well as delays in maintenance.
[0042] In view of the above, embodiments of this application provide a hydrogen production power source and a hydrogen production system, which aim to solve at least one of the above-mentioned technical problems.
[0043] According to the first aspect of this application, please refer to Figure 1 This application provides a hydrogen production power supply, which includes a thermal management component 1, a first power unit 2, a second power unit 3, and a cabinet 5. The first power unit 2 is disposed on one side of the thermal management component 1 along a first direction X and is thermally connected to the thermal management component 1. The second power unit 3 is disposed on the side of the thermal management component 1 away from the first power unit 2 along the first direction X and is thermally connected to the thermal management component 1. The thermal management component 1, the first power unit 2, and the second power unit 3 are all disposed inside the cabinet 5.
[0044] In this embodiment, by placing the thermal management component 1 between the first power unit 2 and the second power unit 3, the thermal management component 1 can uniformly exchange heat for the first power unit 2 and the second power unit 3, thereby improving the heat exchange uniformity while achieving effective heat exchange of the power units. At the same time, by placing the thermal management component 1, the first power unit 2 and the second power unit 3 all inside the cabinet 5, the thermal management component 1 can be integrated into the hydrogen production power supply, thereby achieving the integration of the entire hydrogen production power supply, effectively reducing the overall volume of the hydrogen production power supply and reducing equipment costs.
[0045] It should be noted that, in this embodiment, the thermal management component 1 is positioned between the first power unit 2 and the second power unit 3, forming a symmetrical layout. This allows the thermal management component 1 to simultaneously establish efficient thermal conductive connections with both the first power unit 2 and the second power unit 3 on both sides. This effectively shortens the heat transfer path and allows for a more even distribution of the coolant for refrigeration and heat exchange, avoiding the localized overheating problem that may occur when the coolant flow is insufficient on one side in traditional heat dissipation methods. This effectively improves the overall operational stability of the hydrogen production power supply.
[0046] It should also be noted that integrating the thermal management component 1, the first power unit 2, and the second power unit 3 into the same cabinet 5 eliminates the complex connecting pipelines between the hydrogen production power supply and the heat exchanger compared to the separate setting of the hydrogen production power supply and the heat exchanger. This improves the integration of the hydrogen production power supply, thereby effectively reducing the overall size of the hydrogen production power supply and lowering the equipment cost.
[0047] It should also be noted that the first power unit 2 and the second power unit 3 can be identical power units or power units with different power ratings. The first power unit 2 and the second power unit 3 can be rectifiers.
[0048] It should also be noted that cabinet 5 adopts a high protection level solution, meeting the IP54 standard (an international standard established by the International Electrotechnical Commission, where IP stands for Ingress Protection, which specifically refers to the equipment enclosure's ability to protect against the intrusion of solid foreign objects (such as dust) and liquids (such as water). IP54 indicates that the solid protection level can protect against solid objects larger than 1mm, the dust protection level can protect against water splashes from any direction) and above. This can meet the needs of indoor or outdoor applications and improve product reliability and service life.
[0049] Alternatively, please refer to Figure 2 and Figure 3 In some embodiments, the thermal management component 1 includes a cooling unit 11, a first heat exchange unit 12, and a second heat exchange unit 13. The cooling unit 11 is disposed between the first power unit 2 and the second power unit 3 along a first direction X. The first heat exchange unit 12 is connected to the cooling unit 11 and is thermally connected to the first power unit 2. The second heat exchange unit 13 is connected to the cooling unit 11 and is thermally connected to the second power unit 3.
[0050] In this embodiment, the first heat exchange unit 12 is used to exchange heat with the first power unit 2, the second heat exchange unit 13 is used to exchange heat with the second power unit 3, and the cooling unit 11 is used to exchange heat between the first heat exchange unit 12 and the second heat exchange unit 13, thereby exchanging the heat absorbed by the first heat exchange unit 12 and the second heat exchange unit 13 with the power unit, and achieving cooling of the first heat exchange unit 12 and the second heat exchange unit 13. This application sets the first heat exchange unit 12 and the second heat exchange unit 13 to exchange heat separately, effectively reducing the heat exchange path, that is, shortening the heat transfer distance from the power unit to the cooling unit 11, and reducing heat loss during the transfer process.
[0051] It should be noted that the first heat exchange unit 12 and the second heat exchange unit 13 exchange heat along separate paths, which can be adjusted in a targeted manner according to the actual heating conditions of the first power unit 2 and the second power unit 3, effectively avoiding the waste of heat exchange resources and improving the energy efficiency of the hydrogen production power source.
[0052] It is understandable that the first heat exchange unit 12 and the second heat exchange unit 13 operate independently without interfering with each other. If one of them fails, the other can still cooperate with the cooling unit 11 to provide cooling, maintaining the continued operation of some power units of the hydrogen production power supply. This improves the fault response capability of the hydrogen production power supply and maintains its operational stability.
[0053] Alternatively, please refer to Figure 4 In some embodiments, the hydrogen production power source includes a plurality of first power units 2 and a plurality of second power units 3. The plurality of first power units 2 are arranged along a first direction X on one side of the cooling unit 11. The plurality of first power units 2 are all thermally connected to the first heat exchange unit 12. The plurality of second power units 3 are arranged along the first direction X on the side of the cooling unit 11 away from the first power units 2. The plurality of second power units 3 are all thermally connected to the second heat exchange unit 13.
[0054] In the embodiments of this application, the hydrogen production power supply integrates multiple first power units 2 and multiple second power units 3, which can effectively improve the power of the hydrogen production power supply and achieve a greater power supply.
[0055] In this embodiment, multiple first power units 2 are arranged along the first direction X and all use the first heat exchange unit 12 for heat dissipation; multiple second power units 3 are arranged along the first direction X and all use the second heat exchange unit 13 for heat dissipation; this can improve the ability of a single heat exchange unit to adapt to multiple power units, and use one heat exchange unit to transfer the heat of multiple power units to the cooling unit 11. The heat dissipation path is unified, which can effectively improve the integration of heat dissipation pipe distribution, facilitate subsequent system maintenance, and effectively optimize the internal space layout of the cabinet 5.
[0056] Alternatively, please refer to Figure 5 In some embodiments, the first heat exchange unit 12 includes a first heat exchange pipe 121 and a plurality of first liquid cooling plates 122. The first heat exchange pipe 121 is connected to the cooling unit 11, and the plurality of first liquid cooling plates 122 are all connected to the first heat exchange pipe 121. Each first liquid cooling plate 122 is thermally connected to a first power unit 2. The second heat exchange unit 13 includes a second heat exchange pipe 131 and a plurality of second liquid cooling plates 132. The second heat exchange pipe 131 is connected to the cooling unit 11, and the plurality of second liquid cooling plates 132 are all connected to the second heat exchange pipe 131. Each second liquid cooling plate 132 is thermally connected to a second power unit 3.
[0057] In this embodiment, the first liquid cooling plate 122 and the second liquid cooling plate 132 are used for one-to-one targeted heat exchange with the power unit, and transfer the heat generated by the power unit to the heat exchange pipeline. The first heat exchange pipeline 121 and the second heat exchange pipeline 131 are used to connect to the cooling unit 11 for heat exchange, thereby achieving effective heat dissipation of the hydrogen production power supply.
[0058] It should be noted that in this embodiment, the liquid-cooled plate has a large heat exchange area. By attaching the liquid-cooled plate to the power unit, rapid and uniform heat exchange is achieved. Simultaneously, the heat exchange unit, which combines heat exchange pipes with the liquid-cooled plate, enables point-to-point heat conduction. The heat absorbed by multiple liquid-cooled plates is uniformly transferred to the cooling unit 11 through the heat exchange pipes, achieving both distributed collection and centralized heat exchange, effectively improving heat exchange efficiency.
[0059] It should also be noted that, in the embodiments of this application, the plurality of first liquid cooling plates 122 can be connected in series with the first heat exchange pipeline 121 or in parallel with the first heat exchange pipeline 121. Similarly, the plurality of second liquid cooling plates 132 can be connected in series with the second heat exchange pipeline 131 or in parallel with the second heat exchange pipeline 131.
[0060] Optionally, in some embodiments, the first heat exchange pipeline 121 and the second heat exchange pipeline 131 are both formed by sealing and splicing multiple pipes.
[0061] In this embodiment, by configuring both the first heat exchange pipeline 121 and the second heat exchange pipeline 131 as a combined pipe consisting of multiple sealed and spliced pipes, the flexibility and adaptability of the pipeline layout can be effectively improved, facilitating rapid capacity expansion of the hydrogen production power source. Specifically, the length of the heat exchange pipeline can be flexibly adjusted according to the arrangement of the power units.
[0062] Meanwhile, heat exchange pipelines assembled from multiple pipes can effectively reduce manufacturing and transportation costs, and can be assembled on-site into pipelines of the desired length. In the event of localized pipeline damage, the heat exchange pipeline can be quickly maintained by replacing the affected section.
[0063] It should be noted that the multiple pipes in this embodiment can be connected using quick-release clamps. The connection between the liquid cooling plate and the pipes can be made using a tee connector or a tee valve. Furthermore, the pipes in this embodiment can be stainless steel pipes or rubber pipes.
[0064] Alternatively, please refer to Figure 5 In some embodiments, a plurality of first liquid cooling plates 122 are connected in parallel and connected to a first heat exchange pipeline 121; a plurality of second liquid cooling plates 132 are connected in parallel and connected to a second heat exchange pipeline 131.
[0065] In this embodiment, multiple liquid cooling plates are connected in parallel and connected to heat exchange pipes. This allows each liquid cooling plate to directly obtain coolant or cooling medium from the heat exchange pipes, and the coolant flow rate of each liquid cooling plate is relatively independent. Specifically, the coolant is distributed to multiple liquid cooling plates through the heat exchange pipes, completes heat exchange, and then flows back to the heat exchange pipes. This ensures that each liquid cooling plate receives a similar coolant flow rate and temperature, thereby achieving approximately consistent heat dissipation effects across multiple power units and uniform heat exchange. Specifically, the coolant in the first heat exchange pipe 121 is evenly distributed to multiple first liquid cooling plates 122, and the coolant in the second heat exchange pipe 131 is evenly distributed to multiple second liquid cooling plates 132.
[0066] It should be noted that the parallel connection of multiple first liquid cooling plates 122 and multiple second liquid cooling plates 132 ensures that the remaining first liquid cooling plates 122 and second liquid cooling plates 132 continue to operate stably for heat exchange even if one or more of the first liquid cooling plates 122 or one or more of the second liquid cooling plates 132 fail. This improves the fault tolerance and redundancy of the entire thermal management component 1. Furthermore, each first liquid cooling plate 122 and each second liquid cooling plate 132 can be independently controlled, enabling corresponding flow control and effectively avoiding energy waste, thus reducing energy consumption.
[0067] Alternatively, please refer to Figure 4 In some embodiments, the number of first power units 2 and second power units 3 are equal.
[0068] In this embodiment, by setting the number of the first power unit 2 and the second power unit 3 to be equal, the power units of the hydrogen production power supply can be symmetrically arranged relative to the cooling unit 11 of the thermal management component 1. This allows the heat generated on both sides to form a relatively symmetrical distribution. At this time, the load of the first heat exchange unit 12 and the second heat exchange unit 13 of the thermal management component 1 can be relatively balanced, avoiding excessive load on one side of the heat exchange unit, which is conducive to achieving uniform heat exchange.
[0069] In addition, the symmetrical arrangement of power units enables a more regular layout within the cabinet 5, which is conducive to the regular layout of the first heat exchange unit 12 and the second heat exchange unit 13, reduces pipe crossings and component interference, and helps to improve space utilization.
[0070] Alternatively, please refer to Figure 1 In some embodiments, the thermal management component 1 further includes a refrigeration pipe 14, which is connected to the cooling unit 11 and is thermally connected to the first heat exchange unit 12 and the second heat exchange unit 13 respectively; the refrigeration pipe 14 is used to connect to an external cold source system.
[0071] In this embodiment, by connecting the refrigeration pipe 14 to the cooling unit 11 and partially placing it within the cooling unit 11, and by connecting the refrigeration pipe 14 to an external cold source system, the cooling medium provided by the external cold source system can circulate within the refrigeration pipe 14. The refrigeration pipe 14 exchanges heat with the first heat exchange pipe 121 and the second heat exchange pipe 131, thereby achieving effective heat exchange between the coolant in the first heat exchange pipe 121 and the second heat exchange pipe 131. After the coolant in the first heat exchange pipe 121 and the second heat exchange pipe 131 is cooled, it continues to circulate into the corresponding liquid cooling plate and absorbs heat from the power unit, thus achieving cyclic heat exchange.
[0072] It should be noted that by setting up the refrigeration pipeline 14, this application can separate the flow path of the external cold source system from the internal heat exchange flow path, improve the mobility of the hydrogen production power source, prevent the external cooling medium from entering the power unit of the hydrogen production power source, reduce the flow path of the cooling medium, and thus reduce the risk of leakage of the external cooling medium.
[0073] Alternatively, please refer to Figure 2 In some embodiments, a control unit 4 is also included. The control unit 4 is disposed on one side of the cooling unit 11 along the second direction Y. The control unit 4 is communicatively connected to the cooling unit 11, the first heat exchange unit 12, the second heat exchange unit 13, the first power unit 2, and the second power unit 3, respectively. The first direction X intersects with the second direction Y.
[0074] In this embodiment, by arranging the control unit 4 and the cooling unit 11 adjacent to each other along the second direction Y, the control unit 4 avoids occupying internal space of the cabinet 5 in the first direction X, which is beneficial to improving the utilization rate of internal space of the cabinet 5 and reducing its size. Simultaneously, in this embodiment, the control unit 4 is positioned symmetrically to the hydrogen production power supply and adjacent to the cooling unit 11. This facilitates wiring layout, reduces wiring, and also reduces the communication distance between the control unit 4 and the first power unit 2, the second power unit 3, the first heat exchange unit 12, and the second heat exchange unit 13, thereby maintaining control accuracy and system operational stability.
[0075] It is understood that in this embodiment, the control unit 4 mainly integrates the control modules of the power unit and the control modules of each unit of the thermal management component 1 into a unified control unit 4. This effectively reduces the size of the control unit 4 and enables coordinated control of the power unit and the thermal management component 1. For example, the control unit 4 of the hydrogen production power supply can directly control the operation of each power unit and each unit of the thermal management component 1, improving temperature control accuracy and reliability, reducing the number of components, and lowering the failure rate and cost.
