[0002] As the core equipment in the field of renewable energy, the development of inverters is closely related to technological progress. Since the birth of thyristors (SCR) in the 1950s, the foundation of inverter technology has been laid. Subsequently, key components such as gate turn-off thyristors (GTOs), power field effect transistors (MOSFETs) and insulated gate transistors (IGBTs) have been introduced, which has greatly promoted the development of inverters towards large capacity and high efficiency. Entering the 21st century, with the continuous progress of power electronics technology, microelectronics technology and modern control theory, inverters are moving towards high frequency, high efficiency, high power density and intelligence.

[0003] However, in the prior art, inverters also face some challenges, especially the problem of unreasonable layout is becoming increasingly prominent. The layout design of the internal components of the inverter is directly related to its heat dissipation performance, the difficulty of troubleshooting, and the convenience of maintenance. Unreasonable layout often leads to the inability to effectively dissipate internal heat after the inverter has been running for a long time, causing the temperature to be too high, which in turn affects the overall performance and life of the inverter, and even triggers the overheating protection mechanism to cause shutdown. In addition, unreasonable layout also makes it difficult for technicians to quickly locate the source of the problem during troubleshooting and maintenance, which increases maintenance time and cost and reduces the overall operating efficiency of the system.

[0033] Figures 1 to 4 As shown, in the first aspect, an embodiment of the present application provides an inverter layout structure, including a mounting shell 100 , a main control module 200 , an interaction module 210 , a power board 220 , an AC / DC module 230 and a DC / DC module 240 .

[0034] like Figure 1 As shown, the mounting shell 100 is a rectangular shell structure with an opening. Figure 2 As shown, the opening of the installation shell 100 is opened at the top, and the internal space of the installation shell 100 includes a first chamber 140 and a second chamber 150. Exemplarily, the first chamber 140 and the second chamber 150 can be connected or isolated.

[0035] like Figure 3 As shown, the main control module 200 is installed on the inner wall of the first chamber 140 . The interaction module 210 is installed on the inner wall of the first chamber 140 .

[0036] like Figure 3 As shown, the power board 220 is disposed at the bottom of the second chamber 150. The AC / DC module 230 is installed in the second chamber 150 and is located on the power board 220. The DC / DC module 240 is installed in the second chamber 150 and is located on the power board 220.

[0037] Installing components with relatively high heat generation, such as the power board 220 , the AC / DC module 230 , and the DC / DC module 240 , at the bottom of the second chamber 150 is beneficial to natural convection and radiation heat dissipation of heat.

[0038] Installing components that are more sensitive to electromagnetic interference, such as the main control module 200 and the interactive module 210, in the first chamber 140 and physically isolating them from the AC / DC module 230 and the DC / DC module 240 helps reduce electromagnetic interference and improve stability and reliability.

[0039] By dividing the internal space of the inverter into different chambers and reasonably arranging them according to the actual size and functional requirements of each module, the space in the installation shell 100 can be maximized, making the entire inverter compact, small in size, light in weight, and easy to install and transport.

[0040] The main control module 200 and the interactive module 210 are distributed in the first chamber, and the power board 220, the AC / DC module 230 and the DC / DC module 240 are distributed in the second chamber, realizing a modular design. This design reduces the coupling between the modules, and when a module needs to be repaired or replaced, it can be done more conveniently and quickly without disassembling the entire inverter, thereby improving maintenance efficiency.

[0041] Exemplarily, auxiliary heat dissipation devices such as heat sinks are provided in the first chamber 140 and the second chamber 150 to further improve the heat dissipation effect and ensure that the inverter can maintain stable performance during long-term high-load operation.

[0042] Exemplarily, the first chamber 140 and the second chamber 150 are separated by an electromagnetic shielding material to further enhance the electromagnetic shielding effect.

[0043] like Figure 1 As shown, in one embodiment, the inverter layout structure also includes a cover plate 300, which is detachably mounted at the opening at the top of the mounting shell 100. The top of the mounting shell 100 is provided with an opening for easy maintenance. The cover plate 300 is arranged at the opening of the mounting shell 100. The cover plate 300 can block the opening to prevent debris from entering the first chamber 140 and the second chamber 150. The cover plate 300 is detachably mounted at the opening of the mounting shell 100, so that the cover plate 300 can be removed to open the opening of the mounting shell 100 for maintenance.

[0044] In one embodiment, the inverter layout structure further includes a connection component, and the cover plate 300 and the mounting shell 100 are detachably connected via the connection component. Figure 4 As shown, the connection assembly includes a connection sleeve 110 and a connection bolt (not shown in the drawings).

[0045] The connecting sleeve 110 is a sleeve structure arranged along a straight line and having openings at both ends. The two openings of the connecting sleeve 110 are respectively a first opening and a second opening. One end of the connecting sleeve 110 provided with the second opening is fixed to the mounting shell 100. The bottom of the mounting shell 100 is provided with a matching through hole communicating with the second opening, and a threaded hole is provided on one side of the cover plate 300 close to the first opening. Exemplarily, the connecting sleeve 110 is fixedly mounted on the bottom of the mounting shell 100 by welding, gluing, integral molding or clamping.

[0046] One end of the connecting bolt is threadedly matched with the first opening, and the other end of the connecting bolt is threadedly matched with the threaded hole, and the cover plate 300 is fixed to the opening of the installation shell 100 by the connecting bolt.

[0047] During use, the connecting bolt is first installed into the connecting sleeve 110 from the matching through hole, the connecting bolt enters the second opening from the matching through hole, and then enters the connecting sleeve 110 from the second opening, part of the screw of the connecting bolt extends from the first opening, the part of the screw of the connecting bolt extending from the first opening is threadedly matched with the threaded hole of the cover plate 300, and the part of the screw of the connecting bolt located in the connecting sleeve 110 is threadedly matched with the internal thread on the inner wall of the first opening.

[0048] More than two connection components are provided, at least one connection component is distributed in the first chamber 140, at least one connection component is distributed in the second chamber 150, and the matching through holes are provided correspondingly to the connection components.

[0049] Exemplarily, two connection components are provided, one connection component is distributed in the first chamber 140, and the other connection component is distributed in the second chamber 150. Figure 4 As shown, in another embodiment, four connecting components are provided, the mounting shell 100 is a rectangular structure, and the four connecting components are respectively provided at the four corners of the rectangular structure of the mounting shell 100, that is, two connecting components are provided in the first chamber 140, and the other two connecting components are provided in the second chamber 150.

[0050] In one embodiment, an end cover is provided at the mating through hole on the mounting shell 100. The end cover is detachably provided at the mating through hole to close the mating through hole and prevent debris from entering the mating through hole. When the connecting bolt needs to be installed, the end cover is removed to open the mating through hole.

[0051] like Figure 1 and Figure 2 As shown, in one embodiment, a first ventilation channel 120 is provided on the inner wall of the first chamber 140 to connect the first chamber 140 with the outside.

[0052] like Figure 1 and Figure 2 As shown, in one embodiment, a plurality of first ventilation channels 120 are provided.

[0053] The first ventilation channel 120 increases the heat exchange area between the first chamber 140 and the outside, which is conducive to quickly discharging the heat in the first chamber 140 and reducing the internal temperature. This is of great significance for improving the heat dissipation effect of the electronic components inside the mounting case 100 and extending its service life.

[0054] The plurality of first ventilation channels 120 can form more air flow paths, increasing the uniformity and efficiency of air circulation. This helps to reduce local overheating and make the temperature distribution in the first chamber more uniform. Through effective heat dissipation, it can ensure that the electronic components inside the mounting shell work within a suitable temperature range, avoiding performance degradation or failure caused by high temperature, thereby improving the stability and reliability of the entire system.

[0055] The first ventilation channel 120 allows external air to smoothly enter and exit the first chamber 140 , which helps to reduce dust accumulation in the chamber.

[0056] like Figure 3 As shown, in one embodiment, a second ventilation channel 130 is provided on the inner wall of the second chamber 150 to connect the second chamber 150 with the outside.

[0057] like Figure 3 As shown, in one embodiment, a plurality of second ventilation channels 130 are provided.

[0058] The second ventilation channel 130 increases the heat exchange area between the second chamber 150 and the outside, which is conducive to quickly discharging the heat in the second chamber 150 and reducing the internal temperature. This is of great significance for improving the heat dissipation effect of the electronic components inside the mounting case and extending their service life.

[0059] The plurality of second ventilation channels 130 can form more air flow paths, increasing the uniformity and efficiency of air circulation. This helps to reduce local overheating and make the temperature distribution in the second chamber more uniform. Through effective heat dissipation, it can ensure that the electronic components inside the mounting shell work within a suitable temperature range, avoiding performance degradation or failure caused by high temperature, thereby improving the stability and reliability of the entire system.

[0060] The second ventilation passage 130 allows external air to smoothly enter and exit the second chamber 150 , which helps to reduce dust accumulation in the chamber.

[0061] like Figure 1 and Figure 2 As shown, in one embodiment, the interaction module 210 includes a button unit 212 , which is disposed on the outer wall of the mounting housing 100 near the first cavity 140 .

[0062] For example, through the button unit 212, the user can easily send instructions to the inverter, such as starting, stopping, adjusting the output power, etc. The button unit 212 is directly arranged on the outer wall of the mounting shell 100, so that the user can directly operate without opening the inverter housing, which greatly improves the convenience of use. The user only needs to simply press the button unit 212 to control the inverter. This intuitive operation method reduces the learning cost and improves the user experience.

[0063] In one embodiment, the interaction module 210 further includes an indicator light unit, which is disposed on the outer wall of the mounting housing 100 near the first chamber 140 .

[0064] For example, the main control module 200 displays the current status information of the inverter, such as the operating status, fault alarm, etc., to the user through the indicator light unit of the interactive module 210, thereby enhancing the interactivity of the system and the user's perception. For example, the indicator light unit flashes a red light to indicate a fault, the indicator light unit flashes a green light to indicate a good operation, and the indicator light unit flashes a white light to indicate waiting. This is only an example, and the protection scope of this application is not limited to this.

[0065] For example, the user sends a control instruction to the main control module 200 through the interactive module 210. After receiving the instruction, the main control module 200 controls the power board 220 and the AC / DC module 230 and DC / DC module 240 thereon to perform corresponding operations. At the same time, the main control module 200 feeds back the status information of the inverter to the user through the indicator light unit of the interactive module 210, such as the operating status, fault alarm, etc.

[0066] In a second aspect, an embodiment of the present application further provides an inverter, which adopts the inverter layout structure described in any of the above embodiments.

[0067] In all examples shown and described herein, any specific values ​​should be interpreted as merely exemplary and not as limiting, and thus other examples of the exemplary embodiments may have different values.

[0068] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0069] The above-mentioned embodiments only express several implementation methods of the present invention, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
