Abstract
Description
Technical Field
[0001] This utility model relates to the field of power electronics technology, and in particular to a hydrogen production power supply device and system. Background Technology
[0002] Hydrogen power supplies play a crucial role in hydrogen production systems, serving as core equipment connecting electrolyzers and various power grids.

[0003] The hydrogen production power supply in the above scheme uses liquid cooling to dissipate heat from each module component. However, the above scheme does not have any anti-leakage measures. If the coolant leaks at the pipe connection, it can easily cause equipment failure or even danger. In addition, the liquid cooling pipe path in this scheme is relatively long, which increases the pipe resistance and layout cost and affects the heat dissipation efficiency.
[0004] It should be noted that the information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model, and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art.

[0027] Please see Figure 1 and Figure 2 , Figure 1 A schematic diagram of a hydrogen production power supply device provided in an embodiment of this utility model; Figure 2 This is a schematic diagram of the power module and inductor module provided in an embodiment of the present invention.
[0028] To address the technical problem of existing hydrogen production power supplies lacking anti-leakage measures, or to achieve at least one or more of the aforementioned advantages, an embodiment of this utility model provides a hydrogen production power supply device. As shown in the figure, the hydrogen production power supply device includes a cabinet 10, a power module 20, an inductor module 30, and a liquid-cooled piping assembly 40.
[0029] The interior of rack 10 is hollow, providing installation space for power module 20 and inductor module 30. Rack 10 has internal partitions dividing its interior into a first chamber 11 and a second chamber 12, which are isolated from each other. Power module 20 and inductor module 30 are respectively housed in the first chamber 11 and the second chamber 12. Power module 20 and inductor module 30 are electrically connected, as shown in the schematic diagram below. Figure 3 As shown.
[0030] The power module 20 has a lower temperature resistance than the inductor module 30. The power module 20 and the inductor module 30 are respectively placed in the first chamber 11 and the second chamber 12, which are isolated from each other. The air in the first chamber 11 and the second chamber 12 is dissipated relatively independently, which can meet the different temperature requirements of different devices and avoid heat accumulation.
[0031] The liquid cooling piping assembly 40 is located in the first chamber 11 and close to the second chamber 12. As illustrated, the liquid cooling piping assembly 40 is situated between the power module 20 and the inductor module 30, and is connected to both modules via piping to dissipate heat. Compared to existing top-mounted liquid cooling piping designs, this design shortens the piping path, reduces piping resistance, and lowers costs.
[0032] Based on the above, such as Figure 4 As shown, the cabinet 10 is also equipped with a leak detection module 50. The leak detection module 50 can detect whether there is coolant leakage at the connection between the power module 20 and the liquid cooling pipe assembly 40, and at the connection between the inductor module 30 and the liquid cooling pipe assembly 40, through a leak detection wire 60, and promptly alarm and trigger a shutdown signal to avoid equipment damage caused by coolant leakage.
[0033] In specific implementation, such as Figure 5 As shown, the leak-proof wire 60 can be composed of at least two strands of wire intertwined and connected to form a circuit. The leak-proof wire 60 runs below the connection points of the power module 20 and the liquid cooling pipe assembly 40, and below the connection points of the inductor module 30 and the liquid cooling pipe assembly 40. When coolant leakage occurs, the leak-proof wire 60 at the corresponding location comes into contact with water, and its resistance changes. The leak detection module 50 detects the change in the resistance value of the leak-proof wire 60 and triggers an alarm and shutdown signal to prevent equipment damage caused by coolant leakage.
[0034] Furthermore, the leak-proof wire 60 can be in multiple segments, which are connected by jumper wires 61. Each segment of the leak-proof wire 60 is located below the connection point between the power module 20 and the liquid cooling piping group 40, or below the connection point between the inductor module 30 and the liquid cooling piping group 40. This establishes a correspondence between each component and its corresponding leak-proof wire 60. When coolant leakage occurs, the resistance value of the corresponding leak-proof wire 60 changes, accurately locating the leak and facilitating maintenance.
[0035] Of course, it is understandable that a control center (not shown) and a control panel (not shown) can also be installed on rack 10. The leak detection module 50 communicates with the control center to trigger alarms and shutdown signals, and displays the precise location of the leak on the control panel for easy maintenance.
[0036] The power module 20 includes a rectifier module 21, a chopper module 22, an AC switch 23, and a DC switch 24. The rectifier module 21 and the chopper module 22 are arranged at intervals in the first chamber 11. The AC switch 23 and the DC switch 24 are also arranged at intervals in the first chamber 11.
[0037] In specific implementation, the rectifier module 21 and the chopper module 22 can include multiple modules. This embodiment takes three rectifier modules 21 and two chopper modules 22 as an example. The three rectifier modules 21 are arranged alternately in the first chamber 11. The two chopper modules 22 and the three rectifier modules 21 are arranged back-to-back and alternately in the first chamber 11.
[0038] AC switch 23 and DC switch 24 are arranged alternately below rectifier module 21 and chopper module 22.
[0039] The liquid cooling piping assembly 40 includes an inlet pipe 41 and an outlet pipe 42. Both ends of the inlet pipe 41 and both ends of the outlet pipe 42 extend downwards towards the rectifier module 21 and the chopper module 22, respectively. The rectifier module 21 is connected to both the inlet pipe 41 and the outlet pipe 42 via piping. The chopper module 22 is connected to both the inlet pipe 41 and the outlet pipe 42 via piping.
[0040] Both the rectifier module 21 and the chopper module 22 are equipped with independent liquid cooling modules (not shown in the figure), which are connected to the inlet pipe 41 and the outlet pipe 42 to achieve liquid cooling heat dissipation. The AC switch 23 and the DC switch 24 are cooled by air.
[0041] Taking the diagram as an example, the connection points of the rectifier module 21 and the liquid cooling pipeline group 40, and the connection points of the chopper module 22 and the liquid cooling pipeline group 40 are located in the middle of the front and the middle of the rear of the hydrogen production power supply device, respectively. This not only shortens the pipeline path, reduces pipeline resistance and cost, but also facilitates pipeline connection and maintenance.
[0042] Furthermore, the power module 20 also includes an air guide chamber 25 and a heat exchange module 26. The air guide chamber 25 is disposed between the rectifier module 21 and the chopper module 22. The heat exchange module 26 is located below and connected to the air guide chamber 25. The heat exchange module 26 is connected to the water inlet pipe 41 and the water outlet pipe 42.
[0043] In practice, the air guide chamber 25 is positioned between the rectifier module 21 and the chopper module 22. The upper and lower ends of the air guide chamber 25 are interconnected, and its top end is spaced apart from the cabinet 10, facilitating the flow of air from the first chamber 11 into the air guide chamber 25. The lower end is connected to the heat exchange module 26, which exchanges heat between the air and coolant in the first chamber 11, thus reducing the temperature. The heat exchange module 26 can be a conventional water-air heat exchange module, and its selection is not limited based on actual needs.
[0044] In some preferred embodiments, the inductor module 30 includes an AC inductor 31 and a DC inductor 32. Specifically, the AC inductor 31 and the DC inductor 32 are spaced apart within the second chamber 12. The AC inductor 31 has an independent liquid-cooling module (not shown) internally, and is connected to the inlet water pipe 41 and the outlet water pipe 42 via pipes to achieve liquid cooling. The DC inductor 32 also has an independent liquid-cooling module (not shown) internally, and is connected to the inlet water pipe 41 and the outlet water pipe 42 via pipes to achieve liquid cooling.
[0045] Furthermore, the inductor module 30 also includes a fan 33. The fan 33 is disposed between the AC inductor 31 and the DC inductor 32, and the air outlet direction of the fan 33 is towards the DC inductor 32. The fan 33 can drive the air in the second chamber 12 to circulate, avoiding heat accumulation. Preferably, the fan 33 is an axial flow fan.
[0046] In some preferred embodiments, the hydrogen production power supply device further includes a plurality of liquid storage tanks 70. The plurality of liquid storage tanks 70 are respectively disposed below the rectifier module 21, the chopper module 22, and on the AC inductor 31 and the DC inductor 32.
[0047] Specifically, several liquid storage tanks 70 are respectively located below the connection points of the rectifier module 21 with the inlet pipe 41 and the outlet pipe 42, below the connection points of the chopper module 22 with the inlet pipe 41 and the outlet pipe 42, below the connection points of the AC inductor 31 with the inlet pipe 41 and the outlet pipe 42, and below the connection points of the DC inductor 32 with the inlet pipe 41 and the outlet pipe 42. When coolant leakage occurs at the connection points, the liquid storage tanks 70 have a certain liquid storage capacity to prevent coolant leakage from causing equipment damage.
[0048] Furthermore, the anti-leakage wires 60 pass through the liquid storage tanks 70 below the rectifier module 21 and the chopper module 22, as well as the liquid storage tanks 70 on the AC inductor 31 and the DC inductor 32. When coolant leaks at the connection point, the leaking coolant flows into the liquid storage tanks 70 and is trapped by them. When the coolant comes into contact with the anti-leakage wires 60, it causes a change in the resistance value of the anti-leakage wires 60. The anti-leakage detection module 50 detects the change in the resistance value of the anti-leakage wires 60 and triggers an alarm and shutdown signal to prevent coolant leakage from damaging the equipment.
[0049] In some preferred embodiments, the hydrogen production power supply unit further includes a plurality of quick-connect connectors 80. These quick-connect connectors 80 are respectively disposed on the rectifier module 21, the chopper module 22, the AC inductor 31, the DC inductor 32, the water inlet pipe 41, and the water outlet pipe 42. The design of the quick-connect connectors 80 ensures that coolant does not leak when the pipes are pulled out, avoiding the need for draining and refilling the entire unit during equipment maintenance, thus saving maintenance time and reducing costs.
[0050] In some preferred embodiments, flange interfaces 90 are provided on the inlet pipe 41 and the outlet pipe 42 respectively, to facilitate the entry and exit of coolant.
[0051] In some preferred embodiments, the present invention also provides a hydrogen production power system, comprising the hydrogen production power device of any one of the above.
[0052] In summary, the hydrogen production power supply device and system provided by this utility model, compared with the prior art, can detect whether there is coolant leakage by using a leak detection module in conjunction with a liquid storage tank set at the connection between the power module and the inductor module and the liquid cooling pipeline group, and can promptly alarm and trigger a shutdown signal. At the same time, the liquid storage tank has a certain liquid storage capacity to avoid equipment damage caused by coolant leakage.
