[0002] A charging pile power inverter is a device that converts alternating current (AC) supplied by the power grid into direct current (DC) required by the electric vehicle battery, or in some cases, converts DC into AC for power supply. Its main function is to realize the conversion and regulation of electrical energy, ensuring that electric vehicles obtain electrical energy safely and stably during the charging process.

Some traditional inverters have heat dissipation vents on the side and dustproof plates for dust prevention, but dust and impurities will accumulate on the dustproof plates after a period of use and need to be cleaned. Furthermore, the dustproof plates of traditional inverters are fixed with multiple bolts, making it inconvenient to disassemble and assemble the heat dissipation plates and not practical. To address these issues, a charging pile power-drawing inverter with multi-layer heat dissipation grooves is proposed. Utility Model Content

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3 The present invention provides an embodiment of a charging pile power inverter with multi-layer heat dissipation grooves, including a housing 1, which is the housing of the charging pile power inverter. A heat dissipation mechanism is provided in the middle of the housing 1, which is used to help dissipate heat when the charging pile power inverter is in use. The heat dissipation mechanism includes a heat dissipation component 2 and a heat dissipation fan 4. The heat dissipation fan 4 is fixedly connected to the rear side of the housing 1, and there are multiple fans, which are used to help control the forced flow of air. Dustproof components 3 are provided on the left and right sides of the housing 1, which are used to prevent external dust and impurities from entering the housing 1.

[0033] like Figure 3 and Figure 6As shown, the heat dissipation assembly 2 includes a heat dissipation plate 22, which is used to assist in heat dissipation. The heat dissipation plate 22 is fixedly connected to the top of the inner wall of the outer shell 1. The heat dissipation plate 22 is an inverted quadrangular frustum shape, which makes it easier for airflow to enter the heat dissipation grooves of the heat dissipation plate 22 from all sides. The heat dissipation plate 22 has three layers of heat dissipation grooves to facilitate faster heat exchange. The upper and lower parts of the heat dissipation plate 22 are provided with heat dissipation longitudinal grooves 221, and the middle part of the heat dissipation plate 22 has multiple heat dissipation transverse grooves 222 to facilitate multi-directional airflow heat exchange. The top surface of the outer shell 1 is fixedly connected with multiple heat dissipation fins 21 to assist in heat dissipation.

[0034] Please see Figures 4-5 Heat exchange fins 11 are fixedly connected to both the left and right sides of the outer casing 1 for heat dissipation. They are installed on the inner and outer walls of the outer casing 1. Multiple heat dissipation vents 13 are provided on both the left and right sides of the outer casing 1 for airflow. Multiple installation ports 12 are provided on both the left and right sides of the outer casing 1 for installation of the dustproof component 3. The front and rear parts of the inner wall of the installation port 12 are fixedly connected to the retaining strips 121, which can be made of metal or plastic. The retaining strips 121 are arc-shaped elastic strips used to limit the position of the mounting block 32.

[0035] Furthermore, the dustproof component 3 includes a mounting frame 31, which is used to connect various components. Mounting blocks 32 are fixedly connected to the four corners of the mounting frame 31 near the outer shell 1, which are used to limit the mounting frame 31. The mounting blocks 32 are movably connected to the mounting port 12. The front and rear sides of the mounting blocks 32 are provided with slots 321, which are used to connect with the slots 121. The slots 121 and the slots 321 are engaged. Multiple auxiliary ports 311 are provided in the middle of the mounting frame 31. The heat exchange plate 11 is movably connected to the auxiliary ports 311. A connection port 312 is provided in the middle of the mounting frame 31. A dustproof net 313 is fixedly connected to the middle of the connection port 312. When the dustproof component 3 is fixed to the outer shell 1, the dustproof net 313 can block the outside of the heat dissipation port 13. Pull plates 314 are fixedly connected to the left and right sides of the mounting frame 31, which are used to pull the mounting frame 31.

[0036] Working principle: When the inverter needs to be cooled, multiple cooling fans 4 are turned on. The cooling fans 4 will force the airflow to flow inside the outer casing 1. When the airflow passes through the three-layer heat dissipation grooves on the heat dissipation plate 22, it will assist the heat dissipation plate 22 in heat exchange. At the same time, the airflow after heat exchange will be sent out through the heat dissipation vents 13 on both sides of the outer casing 1. The heat dissipation fins 21 on the top of the outer casing 1 and the heat exchange plates 11 on both sides will assist the inverter in heat exchange, thereby achieving a more efficient heat dissipation effect.

[0037] When the dust filter 313 of the dustproof component 3 accumulates a certain amount of dust and needs to be cleaned, the pull plate 314 can be pulled to move the mounting block 32 away from the mounting port 12 through the mounting frame 31, so that the retaining strip 121 in the mounting port 12 is disengaged from the retaining slot 321, thereby removing the dustproof component 3 from the outer shell 1. Then the dustproof component 3 can be cleaned or replaced immediately. When installing the dustproof component 3, the heat exchange fins 11 on the side of the outer shell 1 need to be passed through multiple auxiliary ports 311 first, and then the mounting block 32 is inserted into the mounting port 12, so that the retaining strip 121 is locked in the retaining slot 321, thereby restricting the position of the mounting block 32 and fixing the dustproof component 3 to the outer shell 1.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
