[0038] As shown in Figure 1 and Figure 3 The application provides a kind of energy storage control machine, including cabinet 1, grid-connected / off-grid component and input / power component.

[0039] Cabinet 1 is as the main structure of energy storage control machine, plays the role of bearing and protection internal component, therefore, grid-connected / off-grid component and input / power component are all arranged in the internal space of cabinet 1, to grid-connected / off-grid component and input / power component play the role of protection and isolation with external environment.

[0040] Grid-connected / off-grid component includes grid-connected PCB board 2 and off-grid PCB board 3 that are stacked up and down along the thickness direction of cabinet 1, to reduce the space occupied by grid-connected / off-grid component in plane, improve the compactness of structure and space utilization. Meanwhile, this stacked mode also helps to shorten circuit path, improve signal transmission efficiency.

[0041] The input / power assembly also adopts the similar stacking concept, specifically including a DC input PCB board 4 and a power PCB board 5. The two circuit boards are also stacked along the thickness direction of the cabinet 1, effectively reducing the planar space occupation and further enhancing the compactness of the overall structure. It is worth noting that, in order to optimize the heat dissipation performance and air flow, the DC input PCB board 4 is arranged flush with one of the grid-connected PCB board 2 and the off-grid PCB board 3, and the power PCB board 5 is arranged flush with the other one of the grid-connected PCB board 2 and the off-grid PCB board 3, not only making the structure more regular, but more importantly, it ensures the smoothness of the heat dissipation channel and helps the heat dissipation, thereby improving the thermal stability and long-term operation reliability of the system.

[0042] The energy storage control machine provided in the present application not only reduces the required space occupation for installing the device, but also improves the internal space utilization, while ensuring the effective heat dissipation of the device.

[0043] As shown in Figure 1 and Figure 2 , in one specific embodiment of the present application, the energy storage control machine further includes a first heat dissipation fan 6 and a second heat dissipation fan 7. The first heat dissipation fan 6 and the second heat dissipation fan 7 are respectively arranged at the two ends of the cabinet 1, which not only can enhance the heat dissipation effect, but also can effectively avoid the occurrence of heat dissipation blind area or dead angle, thereby ensuring that the heat dissipation demand of each component inside the cabinet can be balanced and fully met, and the performance degradation or failure risk caused by local uneven heat dissipation can be reduced by setting the first heat dissipation fan 6 and the second heat dissipation fan 7. Specifically, the grid-connected / off-grid assembly is located on the air supply path of the first heat dissipation fan 6, and the first heat dissipation fan 6 can directly send cold air to the heat dissipation area of the grid-connected / off-grid assembly, effectively removing the heat generated during its operation. Similarly, the input / power assembly is located on the air supply path of the second heat dissipation fan 7.

[0044] As shown in Figure 1 and Figure 4 , in one specific embodiment of the present application, the energy storage control machine includes a load PCB board 8. The load PCB board 8 is specifically arranged in the cabinet 1, and is located on the air supply path of the first heat dissipation fan 6 or the second heat dissipation fan 7, so as to realize effective heat dissipation of the load PCB board 8 by the first heat dissipation fan 6 or the second heat dissipation fan 7.

[0045] As shown in Figure 1 and Figure 4As shown, in one specific embodiment of this application, the energy storage controller includes a communication PCB board 9. The specific implementation of the communication PCB board 9 includes, but is not limited to, various communication methods such as RS485, GPRS, and WiFi, enabling the energy storage controller to be jointly monitored with mobile terminals such as computers and mobile phones or connected to the Internet, and to achieve remote operation. The communication PCB board 9 is specifically located inside the chassis 1, and the connectors on the communication PCB board 9 extend to the outside of the chassis 1, facilitating easy access for connected devices.

[0046] like Figure 1 As shown, in one specific embodiment of this application, the energy storage controller includes an interactive panel 10, which is located on the front end of the chassis 1. This facilitates the setting and adjustment of various functions and parameters of the energy storage controller, and also displays the real-time operating status and key information of the energy storage controller, such as power, voltage, and current. The interactive panel 10 can be either a touchscreen or a traditional button to meet the preferences of different users for operation methods and interactive experiences.

[0047] The interactive panel 10 includes a first cover plate 101 and a second cover plate 102. The first cover plate 101 covers the grid-connected / off-grid components and the input / power components, and the second cover plate 102 covers the load PCB board 8 and the communication PCB board 9. Both the first cover plate 101 and the second cover plate 102 are sealed to the chassis 1, and the second cover plate 102 is connected to the chassis 1 by a snap fastener. This allows the second cover plate 102 to be opened and closed easily, thereby facilitating the maintenance of the load PCB board 8 and the communication PCB board, which require frequent maintenance.

[0048] like Figure 1 As shown, in one specific embodiment of this application, the energy storage controller includes a chassis peripheral assembly located at the rear end of the chassis 1. The chassis peripheral assembly includes a heat sink 11 and an inductor, both of which are located on the outside of the chassis 1. As the main components of the energy storage controller requiring heat dissipation, placing the heat sink 11 and the inductor on the outside of the chassis 1 reduces their impact on internal components and allows for direct and rapid heat dissipation to the outside.

[0049] like Figure 1As shown in a specific embodiment of this application, the heat-absorbing end of the heat sink 11 corresponds to the positions of the grid-connected / off-grid components and the input / power components. The first cooling fan 6 and the second cooling fan 7 disperse the heat from the grid-connected / off-grid components and the input / power components inside the chassis 1, preventing heat accumulation and transferring the heat to the heat sink 11. The heat sink 11 then conducts the heat to the outside of the chassis 1, effectively transferring the heat generated by these functional components to the heat-absorbing end of the heat sink 11. The heat dissipation end of the heat sink 11 has multiple heat dissipation fins spaced apart from each other. These heat dissipation fins increase the heat dissipation area of ​​the heat sink 11, allowing it to exchange heat more fully with the surrounding environment, thereby improving heat dissipation efficiency while maintaining the sealed state inside the chassis.

[0050] like Figure 1 As shown, in one specific embodiment of this application, the chassis peripheral components include a third cooling fan 12, and the heat sink 11 and inductor are both disposed on the airflow path of the third cooling fan 12. The third cooling fan 12 can directly deliver outside air to the surface of the heat sink 11 and the inductor, thereby allowing the heat on the heat sink 11 and the inductor to flow away with the airflow, reducing the accumulation of heat inside the chassis.

[0051] like Figure 1 As shown, in a specific embodiment of this application, the inductor specifically includes one or both of a boost inductor 13 or an inverter inductor 14.

[0052] like Figure 1 As shown, in one specific embodiment of this application, the chassis peripheral components also include a cover 15, which has multiple ventilation holes to ensure smooth airflow. The cover 15 is connected to the rear end of the chassis 1, forming a protective space with the chassis 1. The heat sink 11, inductor, and third cooling fan 12 are all located inside the cover 15, making full use of the protective space provided by the cover 15 to ensure the safety and stability of the internal components.

[0053] like ​ As shown in one specific embodiment of this application, the chassis peripheral components also include a mounting bracket 16, a handle, and a latch. Specifically, the mounting bracket 16, as an auxiliary component for chassis installation, is located at the rear end of the chassis 1, allowing the chassis to be securely mounted on the wall. To enhance the portability and mobility of the chassis, a handle is provided on the side of the chassis 1, ensuring that users can easily grip it when carrying or moving the chassis. Furthermore, to ensure the security of the internal equipment, the latch is used to lock the interactive panel 10, effectively preventing unauthorized access and operation.

[0054] Since the hanger, the handle, the lock catch and the like belong to the category of the prior art, and their working principles and operation processes have been widely recognized and applied in the related field, therefore, the specific structure and operation details thereof will not be described here.

[0055] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
