An energy storage inverter

Abstract

This utility model relates to the field of inverter technology and provides an energy storage inverter. It includes a mounting housing, a heat dissipation assembly, a circuit assembly, and a power supply assembly. An isolation frame is provided on the inner wall of the mounting housing. The heat dissipation assembly, circuit assembly, and power supply assembly are installed at intervals along the isolation frame. After assembly with the heat dissipation assembly, the isolation frame forms a mutually sealed upper cavity and a lower cavity. While improving heat dissipation by having the circuit assembly closely attached to the heat dissipation assembly, the lack of communication between the upper and lower cavities effectively isolates the power supply assembly's working environment from the heat dissipation environment. This prevents moisture or dust from entering the power supply assembly's working environment, thus achieving dustproof and waterproof functions, reducing equipment failure rate, and extending service life.

Description

Technical Field

[0001] This utility model relates to the field of inverter technology, and in particular to an energy storage inverter. Background Technology

[0002] Energy storage inverters are one of the core devices in energy storage systems. They are mainly used in energy storage devices for photovoltaic, wind, and nuclear power generation systems and are key equipment for energy transition. Their technological development is driving the efficient utilization of renewable energy.

[0003] Energy storage inverters are responsible for the efficient conversion between direct current (DC) and alternating current (AC) and for managing the charging and discharging process of energy. Energy storage inverters have bidirectional energy conversion capabilities: in charging mode, they convert AC power from the grid or solar power into DC power for storage in the battery; in discharging mode, they convert DC power from the battery back into AC power to supply loads or feed it back to the grid.

[0004] In existing technologies, to improve the heat dissipation efficiency of power devices inside the cabinet, cooling fans are typically installed inside the energy storage inverter. Directional airflow directly acts on the surface of heat-generating electronic components. However, due to limitations in jet characteristics, uneven airflow distribution leads to localized overheating. Alternatively, passive / active exhaust can create a pressure difference between the inside and outside of the cavity, guiding hot air outwards along a pre-designed air duct. Airflow flows from the cavity of the heat-generating components outwards, but this requires a strictly sealed cavity, resulting in complex duct design. Both of these forced airflow methods can introduce particulate matter (such as dust and fibers) into the equipment, causing short circuits or corrosion. Utility Model Content

[0005] This invention provides an energy storage inverter that solves the technical problems of low heat dissipation efficiency, lack of dustproof and waterproof functions, and consequently high equipment failure rate and short lifespan of existing energy storage inverters.

[0006] To solve the above technical problems, this utility model provides an energy storage inverter, which is provided with a mounting housing and also includes a heat dissipation component, a circuit component and a power supply component. The inner side wall of the mounting housing is provided with an isolation frame. The bottom surface of the isolation frame is covered and equipped with the heat dissipation component, and the top surface is fixedly equipped with the power supply component; after the isolation frame and the heat dissipation component are assembled, they form a mutually sealed and isolated upper cavity and lower cavity. The circuit assembly is installed at the bottom of the upper cavity and is in close contact with the heat dissipation assembly; the bottom of the power supply assembly is fixed to the top surface of the isolation frame and is isolated from the circuit assembly. The upper cavity is not connected to the lower cavity.

[0007] This basic design incorporates an isolation frame on the inner wall of the mounting housing. The heat dissipation assembly, circuit assembly, and power supply assembly are installed at intervals along this frame. The assembly of the heat dissipation assembly and the isolation frame forms a sealed upper and lower cavity. While the circuit assembly is in close contact with the heat dissipation assembly to improve heat dissipation, the lack of communication between the upper and lower cavities effectively isolates the power supply assembly's operating environment from the heat dissipation environment. This prevents moisture or dust from entering the power supply assembly's operating environment, thus achieving dustproof and waterproof functions, reducing equipment failure rates, and extending service life.

[0008] In a further embodiment, the isolation frame includes a horizontal plate, a vertical plate, and a connecting plate; the horizontal plate is horizontally and vertically connected to the inner wall of the mounting housing, and the vertical plate extends vertically upward at its end; the vertical plate is parallel to the inner wall of the mounting housing and is connected and fixed to the inner wall of the mounting housing through a plurality of connecting plates; The horizontal plate surrounds the lower part of the mounting housing to form a mounting platform. The mounting platform is provided with first studs that protrude upwards around its perimeter. The top of the first studs is sealed, and the internal screw holes penetrate the mounting platform and communicate with the lower cavity to install the heat dissipation assembly.

[0009] This solution addresses the impact of heat dissipation and power supply components on the operation of the circuit components. It incorporates an isolation frame consisting of a horizontal plate, a vertical plate, and a connecting plate. The horizontal plate allows for a surface-to-surface installation of the heat dissipation component, improving the isolation between the upper and lower cavities. The vertical plate supports the power supply component without affecting the electrical connection between the power supply component and the circuit components. The connecting plate enhances the strength of the isolation frame. Furthermore, the top-sealed first stud for mounting the heat dissipation component further prevents moisture and dust from escaping through the mounting holes, ensuring a dry and clean working environment for the equipment's circuit components.

[0010] In a further embodiment, the installation platform has a second stud that protrudes upward at the front and rear ends. The bottom of the second stud is sealed, and the top is provided with a screw hole for installing the power supply assembly. The vertical plate surrounds the mounting cavity of the circuit assembly to form a barrier, and its top is also nested and connected to the power supply assembly.

[0011] This solution, by setting a vertical plate to support the power supply assembly and configuring a second stud for nested installation, can ensure that the power supply assembly is always stably in a specific position within the mounting housing, avoiding shaking.

[0012] In a further embodiment, the heat dissipation assembly includes a heat sink and two sets of cooling fans. The heat sink includes a base plate and heat dissipation fins disposed on the base plate. The edge of the base plate is fixedly mounted to the bottom surface of the isolation frame by screws. The front of the base plate is in close contact with the circuit assembly, and the heat dissipation fins are distributed on the back. The heat dissipation fins are arranged in pairs to form air ducts. The two sets of cooling fans are respectively installed on both sides of the mounting housing, facing the two ends of the air ducts.

[0013] This design incorporates a radiator with heat dissipation fins, which effectively increases heat dissipation efficiency by expanding the heat dissipation surface. Furthermore, the two sets of cooling fans located at both ends of the air duct further enhance heat dissipation efficiency by increasing the convection rate.

[0014] In a further embodiment, the power supply assembly includes a left battery bracket, a right battery bracket, and a power supply connector. The left battery bracket and the right battery bracket are provided with at least one battery charging position. Each battery charging position is provided with the power supply connector, and the power supply connector is electrically connected to the circuit assembly and the battery pack.

[0015] This design includes at least one battery charging position on both the left and right battery brackets to accommodate the energy storage and discharge of multiple battery packs.

[0016] In a further embodiment, the back of the left and right battery brackets are provided with nested grooves along the edge of the mounting housing. A sleeve is provided at the bottom of the nested groove. The nested groove is nested in the vertical plate. The sleeve is fitted onto the top of the second stud. The screw passes through the sleeve and the second stud in sequence to fix the left battery bracket to the isolation frame.

[0017] This design features nested grooves on the back edges of the left and right battery brackets, close to the mounting housing. A sleeve is provided at the bottom of the nested grooves, which reduces installation difficulty and improves installation stability.

[0018] In a further embodiment, a display assembly is also included, which is installed through the front of the mounting housing. The display assembly includes a panel and a cover plate, buttons, an LCD screen, a PCB board, and at least one electrical connector fixed to the panel. The panel is provided with multiple power interfaces, and the electrical connector is installed on the back of the power interfaces. The LCD screen is electrically connected to the PCB board and the buttons, and the electrical connector, the PCB board, and the buttons are electrically connected to the circuit assembly.

[0019] This solution features a variety of power connectors to meet the power requirements of different interfaces. The display screen improves interaction efficiency, and the buttons for power control further enhance power efficiency.

[0020] In a further embodiment, it also includes an upper shell, a bottom shell, and a support strip; the upper shell covers the top of the mounting housing and is rotatably mounted on the mounting housing via one end of a pivot; the bottom shell covers the bottom of the mounting housing and has upwardly protruding reinforcing strips around its perimeter; the reinforcing strips are closely attached to the four corner sides of the mounting housing and the support strips are mounted on them.

[0021] This solution incorporates nested support strips at the four corners of the mounting housing, which reinforce the housing and provide collision protection.

[0022] In a further embodiment, a latching assembly is also included, the latching assembly comprising a first latch and at least one set of second latches respectively mounted on the side and the back of the mounting housing; The first latch includes a first lock cover and a first latch. The first lock cover is fixedly installed on the upper part of the outer side wall of the mounting housing. The first latch is rotatably installed on the first lock cover and is engaged with the upper housing. The second latch includes a second cover and a second latch. The second cover is fixedly installed on the upper part of the outer side wall of the back of the mounting housing. The second latch is rotatably installed on the second cover and is engaged with the upper housing.

[0023] This solution involves installing first latches on the side and back of the mounting housing, and at least one set of first latches, to form multi-point locking, which can significantly improve the overall sealing stability.

[0024] In a further embodiment, two sets of handles are also included, which are rotatably mounted on both sides of the mounting housing.

[0025] This design features two sets of handles that are rotatably mounted on both sides of the housing. On the one hand, the handles on both sides can suppress the swaying of the housing and prevent damage to internal components due to shaking. On the other hand, the rotatable mounting allows the handles to be folded and fitted to the sides of the housing, saving space occupied during storage or transportation. Attached Figure Description
