[0033] The principles and structures of the present application will be described in detail below with reference to the drawings and embodiments.

[0034] Embodiment: A high-efficiency cooling energy storage cabinet structure, as shown in Figures 1-8 , includes a mounting support 1, a battery energy storage cabinet 2 and a cooling assembly 3. The mounting support 1 has the battery energy storage cabinet 2 placed from bottom to top on the top, and the cooling assembly 3 is arranged on the top of the uppermost battery energy storage cabinet 2. The cooling assembly 3 is connected with the battery energy storage cabinet 2.

[0035] As shown in Figure 2 , the mounting support 1 includes a base 11, wheels 12 and a connecting plate 13. The base 11 is provided with wheels 12 symmetrically on the bottom by bolts, and the wheels 12 are used to move the entire equipment. The left side of the base 11 is provided with a connecting plate 13, and the connecting plate 13 is used to connect the battery energy storage cabinet 2. Every two adjacent battery energy storage cabinets 2 are fixedly connected by the connecting plate 13.

[0036] As shown in Figures 3-6As shown, the battery energy storage cabinet 2 comprises a mounting box 21, a positioning protrusion 22, a positioning concave block 23, a handle 24, a mesh plate 25, a first forced fan 26, a battery placement plate 27 and an aluminum strip 28. The abutting surfaces of two adjacent mounting boxes 21 are respectively provided with the positioning protrusion 22 and the positioning concave block 23. When the two mounting boxes 21 are placed together, the positioning protrusion 22 is inserted into the positioning concave block 23, so as to install and position the two adjacent battery energy storage cabinets 2. The handle 24 is embedded on the front and rear sides of the mounting box 21, so as to facilitate the carrying of the battery energy storage cabinet 2. The battery placement plate 27 is fixedly connected in the mounting box 21 by bolts. The battery is fixed on the battery placement plate 27 by bolts. The left side of the mounting box 21 is fixedly connected with the mesh plate 25 by bolts. The right side of the mesh plate 25 is fixedly connected with the first forced fan 26 by bolts. The right side of the mounting box 21 is provided with a strip-shaped hole 29. The strip-shaped hole 29 and the mesh plate 25 can form air convection. When it is necessary to accelerate heat dissipation, the first forced fan 26 can be controlled to work. External air is sucked in through the strip-shaped hole 29, and then passes through the battery to dissipate heat. Hot air is discharged through the mesh plate 25. The right wall of the mounting box 21 on the left side of the strip-shaped hole 29 is provided with the aluminum strip 28 which is inclined downward. When air passes through the aluminum strip 28, the aluminum strip 28 cools the air, so that the temperature of the air entering the heat dissipation is lower, and the battery is better cooled. At the same time, because the aluminum strip 28 is blocked on the inner side of the strip-shaped hole 29, when there are impurities in the air, the air passes through the aluminum strip 28 and hits the aluminum strip 28, so that the impurities in the air are separated from the air. The impurities fall down, and the air continues to move to the first forced fan 26 to dissipate heat. The aluminum strip 28 can block the impurities and reduce the impurities entering the mounting box 21. The air enters the mounting box 21 to dissipate heat.

[0037] As Figure 7 and Figure 8As shown, the cooling assembly 3 comprises a water tank 31, a heat dissipation aluminum plate 32, a water pipe 33, a heat conduction copper pipe 34, a branch pipe 35, a heat conduction plate 36 and a second forced fan 37. The water tank 31 is mounted on the top of the uppermost mounting box 21. The bottom of the battery placing plate 27 is provided with the heat dissipation aluminum plate 32. The heat dissipation aluminum plate 32 is embedded with the heat conduction copper pipe 34. The embedded part of the heat dissipation aluminum plate 32 is S-shaped. The end of the heat conduction copper pipe 34 is out of the left side of the heat dissipation aluminum plate 32. The water tank 31 is provided with two water pipes 33 for water inlet and outlet. The water inlet pipe is connected with the inlet of the heat conduction copper pipe 34. The water outlet pipe is connected with the outlet of the heat conduction copper pipe 34. When the battery is cooled, the heat of the battery is conducted to the heat dissipation aluminum plate 32 and the heat conduction copper pipe 34. When the water tank 31 works, the water in the heat conduction copper pipe 34 is cooled, so that the heat emitted by the battery can be quickly taken away. The heat dissipation aluminum plate 32 is composed of an aluminum shell 321, an aluminum cover plate 322, a flow guide fin 323 and an L-shaped connecting pipe 324. The heat conduction copper pipe 34 is installed in the aluminum shell 321. The aluminum cover plate 322 is sealed and connected above the aluminum shell 321. The bottom of the aluminum cover plate 322 is provided with at least two groups of flow guide fins 323. The flow guide fins 323 are wave-shaped to increase the contact area with the water flow and better take away the heat. The L-shaped connecting pipe 324 is connected between the aluminum shell 321 and the two water pipes 33. When the water tank works to cool the battery, the water will enter the aluminum shell 321. The water flowing in the aluminum shell 321 can not only cool the battery, but also quickly cool the heat conduction copper pipe 34, improving the cooling effect. The water pipe 33 between two adjacent heat conduction copper pipes 34 is composed of three branch pipes 35. The branch pipe 35 divides the flowing water into small streams. The mounting box 21 at the branch pipe 35 is provided with a heat conduction plate 36. The heat conduction plate 36 is installed staggered with the handle 24. The heat conduction plate 36 is vertically provided with a through hole. The branch pipe 35 is clamped in the heat conduction plate 36. Because the branch pipe 35 divides the flowing water into small streams, the contact area of the water flow with the heat conduction plate 36 is increased. When the water flow passes through the heat conduction plate 36 or flows in the branch pipe 35, the heat in the water flow can be better taken away, so that the water tank can work better. The second forced fan 37 is installed on the water tank 31 above the water pipe 33.

[0038] In use: when the battery energy storage cabinet 2 needs to be cooled, first, according to the needs, the first violent fan 26 is controlled to start working, the first violent fan 26 sucks the air outside through the strip-shaped hole 29 into the installation box 21, when the air passes through the aluminum strip 28, the aluminum strip 28 first cools the air and blocks impurities in the air, then the air enters the installation box 21 to cool the batteries in the installation box 21, when further improving the cooling performance is needed, the water tank 31 is controlled to start working, because of the high thermal conductivity of the heat dissipation aluminum plate 32, and the heat dissipation aluminum plate 32 is hollow inside, the water flow enters the heat dissipation aluminum plate 32 through the L-shaped connecting pipe 324, the heat dissipated by the battery first enters the heat dissipation aluminum plate 32, the water inside the heat dissipation aluminum plate 32 first cools the battery, and the heat dissipated enters the heat dissipation copper pipe 34, the water tank 31 works, because the heat dissipation copper pipe 34 is a kind of high-efficiency heat transfer element, the heat dissipated by the heat dissipation aluminum plate 32 is quickly taken away by using the phase change process of water in the closed pipe to transfer heat, and the water in the heat dissipation aluminum plate 32 can also cool the heat dissipation copper pipe 34, so that the temperature of the heat dissipation copper pipe 34 can be quickly cooled down, the two complement each other, the heat inside the battery energy storage cabinet 2 can be quickly taken away, and the effect of high-efficiency cooling is achieved, at the same time when the water tank 31 works, the second violent fan 37 works at the same time, the heat dissipated by the heat dissipation plate 36 and the water pipe 33 is taken away, and the water entering and flowing out of the water tank 31 is cooled, the water temperature is reduced while the water tank 31 is cooled, the vertical through hole in the heat dissipation plate 36 can let the wind from top to bottom to dissipate heat.

[0039] The device stacks multiple battery energy storage cabinets 2, when one of them needs to be removed or needs to be disassembled because of a problem, the bolts on the connecting plate 13 are unscrewed, and the stacked battery energy storage cabinets 2 can be quickly disassembled.

Furthermore, it should be understood after reading the content of the present application, those skilled in the art can make various modifications or changes to the present application, and these equivalent forms also fall within the scope defined by the appended claims.
