Description

Technical Field

[0001] This utility model belongs to the field of hybrid inverter technology, specifically relating to a hybrid inverter chassis structure and a hybrid inverter. Background Technology

[0002] A hybrid inverter is an intelligent power electronic device that integrates multi-energy management and power conversion functions. Its core features extend beyond the traditional photovoltaic inverter's function of converting DC power from photovoltaic modules to AC power by integrating three additional core capabilities: energy storage battery charging and discharging control, multi-energy interaction (such as grid / generator connection), and automatic switching between grid-connected and off-grid modes. This enables coordinated management of photovoltaics, energy storage, the grid, and loads. The hybrid inverter chassis (or cabinet) is a dedicated enclosure structure that houses the core electrical components of the hybrid inverter, providing physical protection and functional support. It serves as the "hardware carrier" of the hybrid inverter and must simultaneously meet requirements for electrical safety, heat dissipation, layout integration, and environmental adaptability. Existing hybrid inverter chassis suffer from poor heat dissipation and difficulties in hanging installation. Utility Model Content

[0015] Example 1 In this embodiment, a hybrid inverter chassis 1 structure and a hybrid inverter are proposed, which are easy to install and use with excellent heat dissipation.

[0016] like Figure 1 and Figure 2 As shown, in one embodiment of the present invention, the hybrid inverter chassis 1 structure of the present invention includes chassis 1, upper cover 2, lower cover 3, bottom plate 4, air inlet grille 5, cooling fan 6, main heat sink 7, inductor heat sink 8, AC power distribution support plate 9 and AC output support plate 10. The chassis 1 is a structure with a large rear height and a small front height (or can be understood as thicker at the rear and thinner at the front). The upper cover 2 is installed on the upper rear of the chassis 1, and the lower cover 3 is installed on the upper front of the chassis 1 and is adjacent to the upper cover 2. The upper cover 2 is provided with a display screen 13. The bottom plate 4 is provided on the bottom side of the chassis 1 and is provided with several mounting hooks 12. In specific applications, a mounting plate that is compatible with this utility model can be taken first, and the mounting plate can be installed in the working position. The upper and lower parts of the mounting plate protrude outward. After the mounting plate is fixed, this utility model can be suspended on the mounting plate by the hooks. The air intake mesh 5 is located at the bottom left side of the chassis 1. The cooling fan 6 is located inside the chassis 1 and adjacent to the air intake mesh 5. The main heat sink 7 is located at the front bottom side of the chassis 1, and the inductor heat sink 8 is located at the rear bottom side of the chassis 1. The left side of both the main heat sink 7 and the inductor heat sink 8 is adjacent to the cooling fan 6. As the name suggests, the air intake mesh 5 is a mesh plate for air intake. In this utility model, there are 3 cooling fans 6 arranged in a front-to-back sequence. When the cooling fan 6 is activated, the air blows from the air intake mesh 5 into the inductor heat sink 8 and the main heat sink 7. The inductor heat sink 8 and the main heat sink 7 can work together with the cooling fan to achieve efficient heat dissipation. The right side panel of the chassis 1 has an air outlet to dissipate heat. The inductor heat sink 8 is a special component for heat dissipation of inductor components. Its core function is to quickly dissipate the heat generated when the inductor is working through heat conduction and heat convection, so as to prevent the component from failing due to high temperature and ensure the stable operation of the circuit. Please continue to refer to Figure 2 The AC power distribution support plate 9 of this utility model is located at the rear of the chassis 1 and above the inductor heat sink 8. The AC output support plate 10 is located at the front of the chassis 1 and above the inductor heat sink 8. The core function of the AC power distribution support plate 9 is to support the key components of the AC side of the photovoltaic inverter (such as AC terminals, AC contactors, voltage / current sampling resistors, filter capacitors, etc.) and provide physical support and electrical connection foundation for these components, ensuring that the AC power output from the inverter unit can be stably transferred to the subsequent power distribution or grid connection. A turbulence fan 11 is installed on the AC power distribution support plate 9. The turbulence fan 11 is a special heat dissipation component that actively turbulents the airflow and optimizes the heat dissipation field distribution. The core function of the turbulence fan 11 in this utility model is to break the "local thermal stagnation zone" inside the chassis 1 and improve the overall heat dissipation efficiency. The core function of the AC output support plate 10 is to support the "output interface components" of the inverter (such as output terminal blocks, output protection relays, surge protection components, etc.) and organize the wires and circuits on the output side to ensure that the power is safely and compliantly delivered to the outside.

[0017] This utility model also discloses a hybrid inverter, including the aforementioned hybrid inverter chassis 1 structure. The hybrid inverter also includes components such as a control board and a filter module. These components are all installed in appropriate positions within the chassis 1. This is prior art and will not be described in detail here. This utility model achieves better heat dissipation by cooperating with the turbulence fan 11, the cooling fan 6, the main heat sink 7, and the inductor heat sink 8.

[0018] The upper cover 2, lower cover 3 and chassis 1 of this utility model are all equipped with sealing strips at the mating positions, so as to achieve waterproof sealing. The chassis 1, upper cover 2, lower cover 3 and other components are all made of aluminum alloy bending, which greatly improves the overall heat dissipation capacity.

[0019] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
