[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0039] It is inevitable that green hydrogen will gradually replace grey hydrogen. According to the forecast of major international energy organizations, the output of green hydrogen such as water electrolysis will account for 34% in 2030. By 2060, almost all hydrogen demand will be met by low-emission technologies, of which nearly 80% will be water electrolysis. Hydrogen energy is praised by the international community as the clean energy with the greatest development potential in the 21st century. The technological innovation and industrial development of hydrogen energy continue to be favored, so it is necessary to seize the opportunity and commanding heights of industrial development.

[0040] However, the existing hydrogen production power supply structure often needs to consider the heat dissipation problem, so the structural layout is not compact enough. The existing structural layout occupies most of the space of the structure, resulting in a large power supply structure and insufficient space utilization. In order to solve the above technical problems, the embodiment of the present application provides a power supply module, which improves the space utilization of the hydrogen production power supply structure through a compact structural layout, or reduces the volume structure of the power supply module.

[0041] Specifically, see Figures 1 to 3 The embodiment of the present application provides a power module, which includes a box body 1, and a cold plate 2, a rectifier diode 3, a transistor 4 and an inductor module 5 arranged in the box body 1. The box body 1 includes a main body, and a first cover plate 101 and a second cover plate 102 assembled on the main body. In the embodiment of the present application, since the existing power supply structure is mostly a square structure for easy installation and placement, the box body 1 provided in the embodiment of the present application is a cubic structure, and a cavity is arranged in the box body 1; the cold plate 2 is arranged in the box body 1, and the cold plate 2 is provided with a cold channel for heat conduction on its plate surface, and the cold channel is a circulating cold channel so that the power module circulates and dissipates heat; the cold plate 2 is provided with a rectifier diode 3, a transistor 4 and an inductor module 5 along the cold channel, and the order in which the rectifier diode 3, the transistor 4 and the inductor module 5 are arranged on the cold channel is adjustable.

[0042] Preferably, the rectifier diode 2, the transistor 3 and the inductor module 4 form a U shape on the cold plate 2 along the cold channel.

[0043] In a fixed setting of the present application, the rectifier diode 3 is arranged on the cold plate 2 and is arranged at the first position of the cold channel along the water-cooled heat dissipation channel; the transistor 4 is arranged on the cold plate 2 and is located at the second position of the cold channel along the cold channel; the inductor module 5 is arranged on the cold plate 2 and is located at the third position of the cold channel along the cold channel.

[0044] Through the above structural settings, such as Figure 3As shown, the three major heat sources in the power module, namely the rectifier diode 3, the transistor 4 and the inductor module 5, form a U shape along the cold channel on the cold plate 2. Through such a structural layout, the layout of the rectifier diode 3, the transistor 4 and the inductor module 5 on the cold plate 2 is more compact, and the layout of the three major heat sources is arranged around the cold channel of the cold plate 2, which will not affect the heat dissipation effect. While ensuring the heat dissipation effect, the space utilization rate inside the box 1 is improved, or the volume structure of the power module is reduced from the manufacturing perspective.

[0045] In the embodiment of the present application, as mentioned above, the three major heat sources are the rectifier diode 3, the transistor 4 and the inductor module 5, among which the transistor 4 is an IGBT module, which plays a key role as the main functional electronic component of the power module. Therefore, ensuring its good heat dissipation effect is the key to ensuring its excellent performance. The embodiment of the present application sets it at the end position of the cold plate 2, i.e., the third position, to facilitate power-on and circulating heat dissipation.

[0046] In an optional example, the power supply module provided in the embodiment of the present application also includes a metal conductive busbar 6, which is arranged between the transistor 4 and the inductor module 5 to electrically connect the transistor 4 to the inductor module 5. The metal conductive busbar 6 is preferably connected to a copper busbar, which has good electrical and thermal conductivity, as well as good signal transmission capability. By arranging the copper busbar between the transistor 4 and the inductor module 5, when the circuit is turned on, the auxiliary heat conduction function can be further achieved.

[0047] In an optional example, the power module provided in the embodiment of the present application further includes an output capacitor plate 7, which is arranged on the cold plate 2 and close to the rectifier diode 3. The output capacitor plate 7 is used to store energy and stabilize the voltage of the rectifier diode 3. By integrating the output capacitor plate 7 at a position close to the rectifier diode 3, the structure inside the box 1 is further made compact, thereby improving the utilization rate of the space inside the box 1.

[0048] In an optional example, the necessary electronic components of the hydrogen production power supply structure provided in the embodiment of the present application also include a Hall sensor 8, and the Hall sensor 8 is arranged between the rectifier diode 3 and the output capacitor plate 7 along the cold channel.

[0049] In an optional example, the inductor module 5 is constructed by integrating a plurality of inductors and a metal shell into one module.

[0050] Preferably, the inductor module 5 is constructed to integrate three inductors and an aluminum shell into one module. With such a structure, the inductor module 5 can efficiently input direct current, and the three inductors are integrated into one module instead of being dispersed, thereby reducing the space occupied.

[0051] The above is the internal structure layout setting of the power module provided in the embodiment of the present application. Through the compact layout setting of the internal structure, while improving the space utilization, the functions of the electronic components in the power module will not be affected and the heat dissipation effect is good.

[0052] Next, the external structure of the power module provided in the embodiment of the present application is introduced:

[0053] In an optional example, the cold plate 2 provided in the embodiment of the present application is a water-cooled plate, and the cold plate 2 in the box body 1 is provided with a water inlet joint 9 and a water outlet joint 10, and the water inlet joint 9 and the water outlet joint 10 extend outside the box body 1, and accordingly, the first cover plate 101 is provided with positioning holes for fixing the water inlet joint 9 and the water outlet joint 10.

[0054] like Figure 1 As shown, the water inlet joint 9 and the water outlet joint 10 are arranged corresponding to the cold plate 2 inside the box body 1. When extended to the outside of the box body 1, the water inlet joint 9 and the water outlet joint 10 are just located on the surface of the first cover plate 101. The circulating water can be input and output into and out of the cold plate 2 through the water inlet joint 9 and the water outlet joint 10.

[0055] In the embodiment of the present application, the water inlet joint 9 and the water outlet joint 10 are both quick-install joints, which are convenient for installation and removal with the internal cold plate 2.

[0056] It should be noted that, in actual applications, those skilled in the art may also set the cold plate 2 as an air-cooled plate, on which corresponding air inlets and outlets are set to complete an air-cooled cycle. Such flexible changes and adjustments do not deviate from the principles and scope of the present application and should be limited within the scope of protection of the present application.

[0057] In an optional example, a positive electrode output metal bar 11 and a negative electrode output metal bar 12 are provided on the first cover plate 101, and the positive electrode output metal bar 11 and the negative electrode output metal bar 12 are preferably copper bars, and the positive electrode output metal bar 11 is conductively connected to the negative electrode output metal bar 12, and the positive and negative electrode output metal bars are provided on the outer wall of the first cover plate 101 for connecting to an external socket, and the positive electrode output metal bar 11 and the negative electrode output metal bar 12 are conductively connected on the first cover plate 101, which can effectively avoid eddy currents generated by the positive and negative electrodes.

[0058] Furthermore, a through-the-wall terminal 13 for connecting an input line is also provided on the first cover plate 101 , and the through-the-wall terminal 13 is fixed to the first cover plate 101 by screws.

[0059] In an alternative example, Figure 2As shown, the second cover plate 102 is provided with an indicator light 14 , a signal terminal 15 and a debugging network port 16 , and the indicator light 14 , the signal terminal 15 and the debugging network port 16 are used to display the status of the power module.

[0060] For example, the indicator light 14 is divided into different colors to indicate different working states or faults, etc. The signal terminal 15 is used as a device interface to connect external electronic components, and the debugging network port 16 is used by staff to test or debug the power module, etc.

[0061] In an optional example, the second cover plate 102 is further provided with a handle 17 for installing the power module on a cabinet. The power module provided in the present application can be installed in a cabinet or other equipment through the handle 17 for application.

[0062] The above is the external structure layout setting of the power module provided in the embodiment of the present application. Through the above-mentioned layout setting of the external structure, it is closely connected and coordinated with the internal structure to further ensure the normal operation of the power module provided in the embodiment of the present application.

[0063] It should be noted that the power supply module provided in the embodiment of the present application is only introduced and described around the three major heat sources provided in the present application. Other electronic components not involved are existing technologies that can be adjusted and adapted by personnel in this field according to actual conditions, and will not be repeated in this application.

[0064] According to the power module provided in the embodiment of the present application, the power module arranges the three major heat sources, namely the rectifier diode, the inductor module and the transistor, in a U-shaped layout around the cold channel of the cold plate, which does not affect the heat dissipation effect of the three major heat sources, and makes the internal structure layout of the rectifier diode, the inductor module and the transistor in the box more compact, occupies less internal space of the power module, improves the space utilization of the power module, or reduces the volume structure of the power module.
