[0002] An energy storage cabinet is a device for storing electric energy. An energy storage cabinet usually includes a cabinet body and energy storage batteries, busbar assemblies, battery packs, etc. arranged inside the cabinet body. When working, heat will be generated inside the cabinet. Since there are a large number of battery modules in the energy storage cabinet, if the heat is not dissipated in time inside the cabinet, it will affect the internal operation stability of the cabinet. Currently, heat exchangers or air conditioners are usually used for heat dissipation in cabinets on the market. When the heat load is high, there are defects such as large volume of the heat exchanger or air conditioner, incomplete heat dissipation, uneven heat dissipation, difficult installation arrangement, and high cost; or if air ducts are arranged inside a conventional cabinet for heat dissipation, there are defects such as unobvious heat dissipation effect. Summary of the Utility Model

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art shall fall within the protection scope of the present invention.

[0023] The present invention provides a top heat dissipation structure, which includes a top plate structure 1. A cavity 11 is formed inside the top plate structure 1. A vent hole 12 communicating the cavity 11 with the external environment and facing downward is provided on the side of the top plate structure 1. The top plate structure 1 includes a top plate 15 and a bottom plate 16. After the top plate 15 and the bottom plate 16 are connected, they enclose a box-shaped structure. The inside of this box-shaped structure is hollow, which is the cavity 11. The side of the top plate 15 is bent and extends downward to form a vent hole 12 with the edge of the bottom plate 16. In this embodiment, there are two vent holes 12, which are distributed oppositely on the opposite sides of the bottom plate 16.

[0024] A mounting hole 13 communicating with the cavity 11 is provided at the center of the bottom plate 16. The mounting hole 13, the cavity 11 and the vent hole 12 form a hot air flow channel, that is, hot air enters the cavity 11 through the mounting hole 13, then flows along the cavity 11 to the vent hole 12, and finally flows from the vent hole 12 to the external environment. In this embodiment, since the top plate structure 1 is a box-shaped structure, the vent holes 12 are located on both sides of the box-shaped structure, and the mounting hole 13 is located at the center. An exhaust fan structure 14 is installed in the mounting hole 13. Hot air is extracted into the cavity 11 through the exhaust fan structure 14 and the mounting hole 13. Due to the blockage and guidance of the top of the top plate structure 1, the hot air flow will flow to both sides, that is, the side where the vent holes 12 are located, so that the hot air flow can be smoothly discharged to the outside.

[0025] A chamfer 17 is formed at the bent part of the top plate 15 above the vent hole 12. The chamfer 17 has a certain width, and a corresponding chamfer 17 is formed at the top of the cavity 11. In this way, when the hot air flow passes along the cavity 11 through the chamfer 17 surface, it will not accumulate at the bent part to form a backflow or a cyclone effect, so that the hot air flow can quickly enter the vent hole 12 and accelerate the heat dissipation effect.

[0026] In this embodiment, the bottom plate 16 is rectangular, and the air vents 12 are distributed along one set of opposite edges of the bottom plate 16 and are rectangular in shape. After the hot air flow enters the top plate structure 1 from the center, it is first blocked by the top of the top plate structure 1 and diffuses in all directions. Then, blocked by two closed sides of the top plate structure 1, the hot air flow can only flow to the other two sides, that is, the side where the air vents 12 are located. Since the air vents 12 extend along this side, the hot air flow on this side can all flow into the air vents 12.

[0027] A cover plate 18 is provided on the air vents 12. The shape of the cover plate 18 is adapted to the shape of the air vents 12. The cover plate 18 is provided with air holes 19. When the shape of the air vents 12 is rectangular, the shape of the cover plate 18 is also rectangular. The number of air holes 19 is multiple, and the air holes 19 are rectangular and are equidistantly distributed along the length direction of the cover plate 18, and the air holes 19 are horizontally distributed, that is, the length direction of the air holes 19 is perpendicular to the length direction of the cover plate 18. In this way, the air holes 19 can cover the air vents 12 with the largest area, so that the hot air flow in the air vents 12 can be discharged from the air holes 19 to the greatest extent, not only accelerating the discharge speed of the hot air flow, but also preventing the hot air flow from remaining between the air vents 12 and the cover plate 18.

[0028] In addition, in this embodiment, the edge of the bottom plate 16 is bent downward to form a box body structure with an inverted opening shape. In this way, the air vents 12 are located on the side of the bottom plate 16, that is, a groove body structure with a certain depth is formed between the side of the bottom plate 16 and the side of the top plate 15. The opening of the groove body structure faces downward to form the air vents 12.

[0029] The outer side edge of the cover plate 18 is bent upward by 90 degrees and hidden in the air vents 12. When the shape of the cover plate 18 is rectangular, the side edge of the cover plate 18 that is the long side is bent upward by 90 degrees to form a flanging. One flanging fits on the side of the bottom plate 16, and the other flanging fits on the inner side of the side edge where the top plate 15 is bent downward. In this way, when the rainwater flows down along the top plate 15, it will not enter the air vents 12 along the joint between the cover plate 18 and the top plate 15.

[0030] Two opposite short sides of the cover plate 18 and the top plate 15 are fixedly connected by connecting pieces 110. The connecting pieces 110 are thin sheets bent in an L shape. One end of the connecting pieces 110 fits to the edge of the top plate 15 and is fixed by fasteners, and the other end fits to the cover plate 18 and is fixed by fasteners, which is convenient for the loading and unloading of the cover plate 18. Each cover plate 18 corresponds to two.

[0031] The shape of the cover plate 18 is also rectangular, and the air holes 19 are long waist-shaped. Multiple air holes 19 are horizontally equidistantly distributed along the long side direction of the cover plate 18.

[0032] The inner surface of the cover plate 18 is covered with a dust-proof net to prevent dust or foreign objects from entering the cavity 11. The shape of the dust-proof net is the same as that of the cover plate 18. The periphery of the dust-proof net and the cover plate 18 can be fixed to each other by magnetic stickers. The mesh surface of the dust-proof net is made of washable material, which makes the dust-proof net easy to install and disassemble and convenient to clean. While preventing dust, it will not affect the heat dissipation effect.

[0033] The present utility model also provides a waterproof machine, which includes a waterproof cabinet body 2. The top of the waterproof cabinet body 2 is open and is provided with the above-mentioned top heat dissipation structure. In this embodiment, the waterproof cabinet body 2 is connected to the top plate structure 1 through the bottom plate 16. The edge of the top opening of the waterproof cabinet is bent inward by 90 degrees and then fits to the bottom surface of the bottom plate 16 and is fixed by fasteners. Such a design facilitates the installation and disassembly between the waterproof cabinet and the top heat dissipation structure. There is also a U-shaped connecting piece between the top plate 15 and the bottom plate 16. The connecting pieces are respectively located at the four corners of the bottom plate 16. One end of the connecting piece fits and is fixed to the top plate 15 by fasteners, and the other end fits and is fixed to the bottom plate 16 by fasteners to connect the top plate 15 and the bottom plate 16, so that the top plate 15 and the bottom plate 16 can be stably connected. The inside of the waterproof cabinet body 2 is communicated with the cavity 11 through the mounting holes 13. The air extraction fan structure 14 extracts the hot air in the waterproof cabinet body 2 into the cavity 11. The hot air usually moves upward. Therefore, the hot air in the waterproof cabinet body 2 moves from bottom to top to the top and is extracted by the air extraction fan structure 14 at the top. Therefore, such a design makes the heat dissipation effect of the whole waterproof cabinet very remarkable, and the whole vent 12 is located on both sides of the top of the waterproof cabinet body 2, which can play a waterproof role and prevent rainwater from entering the waterproof cabinet body 2 from the top.

[0034] A control component, an inverter component, a battery pack 22 and a busbar component 21 are installed inside the waterproof cabinet body 2. The inverter component is electrically connected to the control component and the battery pack 22. The battery pack 22 is used for storing electric energy. The battery pack 22 is electrically connected to the control component. The control component is electrically connected to the busbar component 21. The busbar component 21 is used for converging current. The specific working process and principle are not elaborated here.

[0035] The present utility model is not limited to the above-mentioned best implementation mode. Anyone can obtain other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in its shape or structure, as long as it has a technical solution identical or similar to that of the present application, it falls within the protection scope of the present utility model.
