[0053] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0054] The present application aims to at least solve the technical problems of complex circuit connection and insufficient heat dissipation capacity existing in the related art. To this end, the present application proposes a hydrogen production power supply, which improves the layout of various components in the housing cavity of the hydrogen production power supply, optimizes the wiring, saves costs, and improves the heat dissipation capacity of the radiator, thereby ensuring the stable operation of the system.

[0055] Reference below Figure 1-Figure 8 A hydrogen production power supply 1 according to an embodiment of the present application is described.

[0056] like Figure 1 As shown, the hydrogen production power supply 1 includes: a housing 10, an AC reactor 110, an AC switch 120, a DC reactor 130, a DC switch 140 and a conversion module 170.

[0057] The housing 10 is the outer shell of the hydrogen production power source 1, and can form a housing chamber 20 for accommodating and protecting the internal electrical and electronic components, and can also play a role in supporting and fixing the internal components, thereby ensuring the stability and safety of the power source.

[0058] In the technical solution of this application, Figure 1 As shown, the upper end can be used as the first vertical end and the lower end as the second vertical end. Figure 8 As shown, the upper end may be used as the first vertical end and the lower end as the second vertical end.

[0059] The AC inductor 110 is installed at the first vertical end of the accommodating cavity 20, and is usually used to filter and stabilize the input AC power supply, which can reduce harmonic interference in the power grid and improve the power quality of the power supply. The DC inductor 130 is installed at the second vertical end of the accommodating cavity 20, and is usually used to filter and stabilize the output DC power supply, and is used to smooth the rectified DC voltage and reduce ripple.

[0060] The AC switch 120 is used to control the on and off of the power supply to realize the functions of starting, stopping and fault protection of the power supply. It can be a circuit breaker, a contactor or other types of switching devices. At least one AC switch 120 is installed at the first vertical end of the accommodating chamber 20. The DC switch 140 is used to control the output of the DC power supply to realize the connection and disconnection with the hydrogen production equipment. It can be a DC circuit breaker, a relay or other types of DC switch 140 devices. At least one DC switch 140 is installed at the second vertical end of the accommodating chamber 20.

[0061] The conversion module 170 is electrically connected between the AC inductor 110 and the DC inductor 130 and is installed in the middle of the accommodating cavity 20. It is the core part of the hydrogen production power supply 1 and is responsible for converting the input AC power supply into a DC power supply suitable for the hydrogen production equipment. It usually includes a rectifier, a filter and possible voltage and current adjustment circuits. The rectifier is used to convert AC power into DC power, and the filter can reduce ripple.

[0062] It can be understood that the hydrogen production power supply 1 is a complex system integrating multiple electrical and electronic components, which is used to convert input electrical energy into electrical energy suitable for hydrogen production. By improving the layout of the components in the accommodating cavity of the hydrogen production power supply, the AC and DC switch wiring can be optimized, the length and complexity of the lines can be reduced, and crossing and overlapping between lines can be avoided, thereby reducing heat accumulation and mutual interference, while facilitating the heat dissipation of the AC and DC switches to ensure the normal operation of the circuit.

[0063] In some embodiments, Figure 1 and Figure 6As shown, at least part of the input end of the hydrogen production power supply 1 is introduced into the accommodating cavity 20 from the first end of the casing 10, and is electrically connected to the AC switch 120 located at the first end; at least part of the output end of the hydrogen production power supply 1 is introduced into the accommodating cavity 20 from the second end of the casing 10, and is electrically connected to the DC switch 140 located at the second end.

[0064] In the technical solution of the present application, the input and output ends of the hydrogen production power supply 1 are connected to the accommodating cavity 20 inside the casing 10 through specific paths and switches, wherein the input end is the input part of the hydrogen production power supply 1, which is used to receive electric energy provided by an external power supply, and at least part of the input end is introduced into the accommodating cavity 20 from the first end of the casing 10. The AC switch 120 is located at the first end of the casing 10, and is used to control the connection and disconnection of the input end with the external power supply. The AC switch 120 can be manually operated by a relay, or automatically controlled by an electronic switch.

[0065] The output end is the output part of the hydrogen production power supply 1, which is used to provide electric energy to external equipment such as an electrolyzer. At least part of the output end is introduced into the accommodating cavity 20 from the second end of the casing 10. The DC switch 140 is located at the second end of the casing 10 and is used to control the connection and disconnection between the output end and the load. Similar to the AC switch 120, the DC switch 140 can be manually operated by a relay or automatically controlled by an electronic switch.

[0066] It can be understood that by electrically connecting the input and output ends of the hydrogen production power supply 1 to the AC switch 120 and the DC switch 140 respectively, the physical separation of the input and output ends can be ensured, reducing electrical interference and safety risks, and the existence of the AC switch 120 and the DC switch 140 makes the operation and control of the hydrogen production power supply 1 safer and more flexible.

[0067] In some embodiments, Figure 1-Figure 5 As shown, the DC switch 140 and the AC switch 120 are respectively installed on the first side and the second side of the accommodating cavity 20 in the front-to-back direction.

[0068] In the technical solution of the present application, the front side is the first side and the rear side is the second side. The DC switch 140 and the AC switch 120 are respectively installed on the first side and the second side of the accommodating cavity 20 in the front-to-back direction. This can better utilize the space and make the circuit layout more compact and reasonable. The DC and AC circuits have different electrical characteristics. Separating them can improve the safety and stability of the circuit, reduce mutual interference, and help improve the heat dissipation effect to prevent excessive heat concentration.

[0069] It is understandable that the specific installation positions of the DC switch 140 and the AC switch 120 in the accommodating cavity 20 are on different opposite sides, which is convenient for wiring, can ensure the neatness and reliability of the circuit, and can also reduce the interference that the switching operation may cause to other electronic equipment.

[0070] In some embodiments, Figure 3 and Figure 4 As shown, a DC connection area 210 is formed on the first side of the accommodating chamber 20 in the front-to-back direction, and the DC connection area 210 is located at the second end of the accommodating chamber 20 in the vertical direction; an AC connection area 220 is formed on the second side of the accommodating chamber 20 in the front-to-back direction, and the AC connection area 220 is located at the first end of the accommodating chamber 20 in the vertical direction.

[0071] In the technical solution of the present application, the DC wiring area 210 is used to connect the DC output terminal of the hydrogen production power supply 1 with the DC input terminal of the external device, and may include a clamp, a socket or other connecting device for fixing and connecting the wires, wherein the external device may be an electrolyzer. The DC wiring area 210 is located on the first side of the accommodating chamber 20 in the front-to-back direction and the second end of the accommodating chamber 20 in the vertical direction, which can make the connection of DC power more convenient and is conducive to the management and wiring of DC wires in the vertical direction.

[0072] The AC wiring area 220 is used to connect the AC input end of the hydrogen production power supply 1 with the AC output end of the external power supply, and may include a clamp, a socket or other connecting device for fixing and connecting wires, wherein the external power supply may be a power grid. The AC wiring area 220 is located on the second side of the accommodating chamber 20 in the front-to-back direction and the first end of the accommodating chamber 20 in the vertical direction, which can separate AC power from DC power, reduce mutual interference, and facilitate the management and wiring of AC wires in the vertical direction.

[0073] It is understandable that arranging DC and AC in different areas can guide the wires to different wiring areas, improve the safety of the circuit, and reduce the potential risks of electrical faults such as short circuits and electric shocks.

[0074] In some embodiments, Figure 3 As shown, the hydrogen production power supply 1 further includes: an auxiliary power switch 160, which is installed on a first side of the accommodating chamber 20 in the front-to-back direction and is located above the DC wiring area 210;

[0075] A communication wiring area 230 and a parallel wiring area 240 are formed on a second side of the accommodating cavity 20 in the front-to-back direction and are located below the conversion module 170 .

[0076] In the technical solution of the present application, there is an external power supply device to supply power to the internal components of the accommodating cavity 20. The auxiliary power supply switch 160 can control the opening and closing of the circuit of the external power supply device to ensure the normal operation of each component, thereby ensuring the safety of the circuit and equipment. The auxiliary power supply switch 160 is installed on the first side of the accommodating cavity 20 in the front-to-back direction, above the DC wiring area 210, to avoid direct interference or influence of the DC current on the switch.

[0077] The wiring area layout of the accommodating chamber 20 is located below the conversion module 170, and includes a DC wiring area 210, an AC wiring area 220, a communication wiring area 230 and a parallel wiring area 240, wherein the DC wiring area 210 is located at the first vertical end of the accommodating chamber 20, and the AC wiring area 220 is located at the second vertical end of the accommodating chamber 20. The DC wiring area 210 has a clear upper and lower relationship with the auxiliary power supply switch 160, and the auxiliary power supply switch 160 is located above the DC wiring area 210. The communication wiring area 230 is located on the second side of the accommodating chamber 20 in the front-to-back direction, and the current and voltage required by the communication line are lower than those of the DC line, and can be placed in a more accessible but relatively safe position, that is, below the conversion module 170. The parallel wiring area 240 is also located on the second side of the accommodating chamber 20 in the front-to-back direction, adjacent to the communication wiring area 230. When multiple power supply devices need to be connected, the wiring work can be carried out in a centralized area for easy operation and management.

[0078] It can be understood that the location of the auxiliary power switch 160 is easy to operate and access, and the modular and regionalized layout of the wiring area ensures the safety and maintenance convenience of different types of lines, making the hydrogen production power supply 1 easier to maintain and manage.

[0079] In some embodiments, Figure 4 As shown, there are multiple AC switches 120 , and the multiple AC switches 120 are spaced apart to form an AC wiring area 220 .

[0080] In the technical solution of the present application, the spaced-apart AC switches 120 make the wiring area clearer and provide sufficient space for the arrangement of wires and cables, making wiring work easier and neater, helping to reduce wire entanglement and confusion, thereby reducing the risk of electrical accidents caused by accidental contact or short circuits, and improving the reliability and maintainability of the system. The spaced-apart layout also helps to improve heat dissipation performance. There is a certain amount of air circulation space between each switch, which can reduce heat accumulation and improve the heat dissipation efficiency of the switch and the entire system.

[0081] It can be understood that spacing the multiple AC switches 120 to form the AC wiring area 220 can ensure the safety and heat dissipation of the hydrogen production power supply 1 system, and contribute to the reliable operation of the hydrogen production power supply 1 system.

[0082] In some embodiments, Figure 3 As shown, the hydrogen production power supply 1 also includes: a control board 150, an AC reactor 110 and an AC switch 120 installed at the upper end of the accommodating chamber 20, the control board 150 is installed at the upper end of the accommodating chamber 20, and the AC reactor 110 is located between the control board 150 and the AC switch 120 in the front-to-back direction.

[0083] In the technical solution of the present application, the control board 150, the AC inductor 110 and the AC switch 120 are all installed at the second end of the accommodating cavity 20 in the vertical direction, and are the control board 150, the AC inductor 110 and the AC switch 120 from front to back. The control board 150 is the core part of the power supply system, responsible for monitoring the power supply status, controlling the operation of each component and communicating with the hydrogen production system. It is installed at the second end of the accommodating cavity 20 for easy operation and maintenance. The main function of the AC inductor 110 is to limit the rate of change of current through inductance characteristics, stabilize the current fluctuation of the power supply system when the power supply is started, stopped or the load changes, prevent current mutations, and thus protect other components in the power supply system. The AC switch 120 is an important component of the power supply system, used to control the on and off of the power supply, and the connection with an external power supply or load, and is also installed at the second end of the accommodating cavity 20.

[0084] It can be understood that the control board 150, the AC inductor 110 and the AC switch 120 are all installed at the upper end of the accommodating cavity 20 and located above the conversion module 170, which makes wiring easier, can reduce the length and complexity of cables, reduce the risk of failure, and at the same time help heat rise and be more effectively discharged from the system through natural convection or a fan. The AC inductor 110 is located between the control board 150 and the AC switch 120, which can ensure that the current passes through the inductor before passing through the switch, thereby protecting the system from the impact of sudden current changes.

[0085] Multiple AC switches 120 and multiple DC switches 140 are installed in the accommodating cavity 20, and there are multiple layouts, including but not limited to:

[0086] First, the AC switch 120 and the DC switch 140 are located at the same end.

[0087] In some embodiments, Figure 6 As shown, the plurality of AC switches 120 are all installed at the first end of the accommodating cavity 20 in the vertical direction, and the plurality of DC switches 140 are all installed at the second end of the accommodating cavity 20 in the vertical direction.

[0088] In this embodiment, multiple AC switches 120 and multiple DC switches 140 will generate heat when working. Distributing them at both ends can avoid excessive concentration of heat and the formation of local high-temperature areas, thereby improving the reliability of the entire power supply system. In addition, AC and DC are different in nature. Separate processing can reduce electrical interference and potential safety risks, and it is also convenient to cut off the power supply of the corresponding circuit in time when an abnormal situation occurs.

[0089] It can be understood that installing the AC switch 120 and the DC switch 140 at different vertical ends of the accommodating cavity 20 respectively can realize the functional partitioning and heat dissipation management of the power supply system, reduce line crossing, reduce interference, and facilitate subsequent maintenance and management, thereby improving the overall performance and reliability of the hydrogen production power supply 1 system.

[0090] Second, the AC switch 120 and the DC switch 140 are located at different ends.

[0091] In some embodiments, Figure 7 As shown, an AC switch 120 is installed at both the first and second vertical ends of the accommodating cavity 20 , and a DC switch 140 is installed at both the first and second vertical ends of the accommodating cavity 20 .

[0092] In this embodiment, in a large system or a distributed system, it is necessary to control the power supply from multiple locations, and multiple AC switches 120 are installed at both ends of the accommodating cavity 20, and multiple DC switches 140 are also installed at both ends of the accommodating cavity 20 for easy operation. When maintaining or repairing the equipment, it is necessary to disconnect the power supply to ensure safety. By installing the AC switch 120 and the DC switch 140 at both ends of the accommodating cavity 20, it can be ensured that the power connection is completely isolated, and the power input type can be changed or replaced without changing other parts.

[0093] It can be understood that an AC switch 120 and a DC switch 140 are installed at each end of the accommodating cavity 20, which can realize the functional partitioning and heat dissipation management of the power supply system, reduce line crossing, reduce interference, and facilitate subsequent maintenance and management, thereby improving the overall performance and reliability of the hydrogen production power supply 1 system.

[0094] In some embodiments, Figure 1 and Figure 2 As shown, the conversion module 170 includes: a PWM module 171 (pulse width modulation module), a capacitor pool 172 and a BUCK module 173 (voltage conversion module).

[0095] The input end of the PWM module 171 is electrically connected to the AC inductor 110, and the output end of the PWM module 171 is electrically connected to the capacitor pool 172; the PWM module 171, the capacitor pool 172 and the BUCK module 173 are distributed in the front-to-back direction, and the PWM module 171 is arranged on the side close to the AC inductor 110, and the BUCK module 173 is arranged on the side close to the DC inductor 130.

[0096] In the technical solution of the present application, the PWM module 171, the capacitor pool 172 and the BUCK module 173 together constitute a system for power conversion, wherein the PWM module 171 is the core part of the conversion module 170, which is arranged on the side close to the AC inductor 110 and is responsible for converting the input AC power into DC power with adjustable pulse width. By adjusting the width of the pulse, the PWM module 171 can control the average voltage and current of the DC power.

[0097] The input end of the PWM module 171 is electrically connected to the AC inductor 110, which is used to filter the input AC power and remove high-frequency noise and clutter therein to ensure that the PWM module 171 receives a stable AC signal. The output end of the PWM module 171 is electrically connected to the capacitor pool 172, which is located between the PWM module 171 and the BUCK module 173 and is used to store electrical energy and smooth the DC power output by the PWM module 171. It can absorb ripples in the output of the PWM module 171, improve the quality of the DC power, and release electrical energy when needed to provide a stable DC power supply.

[0098] The BUCK module 173 is arranged on a side close to the DC reactor 130, and is used to step down or step up the DC power output from the capacitor pool 172 to a required voltage level, thereby ensuring that the DC power output from the capacitor pool 172 can still maintain good stability and ripple performance after voltage transformation.

[0099] In the actual working process, the PWM module 171 serves as the starting point, first converting the AC power into DC power, then the capacitor pool 172 performs energy storage and filtering, and finally the buck module 173 performs voltage adjustment. Placing the PWM module 171 on the side close to the AC inductor 110 can reduce electromagnetic interference to subsequent circuits and facilitate heat dissipation.

[0100] It is understandable that the configuration of the conversion module 170 can effectively convert AC power into stable and controllable DC power, and further optimize and adjust it through the capacitor pool 172 and the BUCK module 173 to meet the needs of different devices and circuits.

[0101] In some embodiments, Figure 2 As shown, the hydrogen production power supply 1 also includes: a first fan 181 , a second fan 182 and a heat exchanger 190 .

[0102] The first fan 181 is installed between the AC switch 120 and the BUCK module 173;

[0103] The second fan 182 is installed between the DC switch 140 and the PWM module 171 and the capacitor pool 172;

[0104] The heat exchanger 190 is installed between the DC switch 140 and the second fan 182 .

[0105] In the technical solution of the present application, the first fan 181 is installed between the AC switch 120 and the BUCK module 173. Its main function is to provide cooling airflow, remove the heat around the components through circulating air, maintain a good ventilation environment inside the system, ensure that these components can operate at an appropriate temperature, and prevent overheating from causing performance degradation or damage. The second fan 182 is installed between the DC switch 140 and the PWM module 171 and the capacitor pool 172. Its function is to provide cooling airflow, accelerate the dissipation of heat inside the system by promoting air flow, maintain the stability and reliability of the power supply, and ensure that these components operate within an appropriate temperature range. The heat exchanger 190 is installed between the DC switch 140 and the second fan 182 to transfer the heat generated by the DC switch 140 to the cooling medium, thereby realizing heat transfer and dissipation. When used in conjunction with the second fan 182, it can significantly improve the heat dissipation efficiency of the heat exchanger 190.

[0106] It can be understood that arranging the first fan 181, the second fan 182 and the heat exchanger 190 near the key heat-generating components can optimize the air flow path inside the system, help form an effective cooling cycle, improve heat dissipation efficiency, ensure that these components are cooled in a timely and effective manner, improve the overall performance and reliability of the power supply, and ensure that the hydrogen production power supply 1 can operate stably under various working conditions.
