In order to make the energy storage cabinet operate normally and efficiently, heat generated by the energy storage cabinet needs to be emitted to ensure that the temperature of the energy storage cabinet is kept in an optimal range. On the other hand, because the battery system in the energy storage cabinet is formed by connecting a plurality of battery cells in series, the capacity of the battery cells is greatly influenced by the running temperature, so that the temperature difference between the inside of the battery module and the battery cells is required to be controlled within a certain range, and the consistency of the working temperature between the battery cells is ensured, which is the key for ensuring the capacity of the energy storage cabinet.

In some embodiments, the air supply mechanism further includes a deflector 28 disposed in the total air supply duct 22 for dispersing cool air blown out from the air supply port 121b of the air conditioning unit 121.
As shown in fig. 3, in this embodiment, the air supply port 121b is provided with the baffle 28, and the cold air blown by the air conditioning unit 121 is blown to the middle of the baffle 28 and is diffused and flows into the central air supply duct 23 and the side air supply duct 24 along the periphery of the baffle 28, so that the excessive wind speed and excessive wind quantity at the air supply port 121b are avoided, the excessive wind quantity in the central air supply duct 23 is caused, the heat exchange efficiency between the battery pack 211 close to the central air supply duct 23 and the cold air is caused to be excessive, the temperature inside the battery pack 211 is caused to be uneven, and the temperature consistency of the battery pack 211 is affected.
In some embodiments, as shown in fig. 4, a honeycomb structure 281 for increasing wind resistance is disposed on the baffle 28 at a position corresponding to the air supply port 121 b.
Because the wind speed at the air supply port 121b is maximum and the air quantity is maximum, if the air guide plate 28 is not arranged for guiding, the heat exchange efficiency near the air supply port 121b is possibly too high, the temperature of the electric core near the air supply port 121b is too low, if the air guide plate 28 is arranged for shielding, all cold air is blown to the periphery, the battery pack 211 near the air supply port 121b does not exchange heat with cold air, therefore, a through honeycomb hole-shaped structure 281 is required to be arranged at the position corresponding to the air supply port 121b on the air guide plate 28, as shown in fig. 4, a column 13 for supporting is arranged in the energy storage cabinet body 1, the battery clusters 21 are arranged on the column 13, a central air supply channel 23 is arranged between the columns 13, the air guide plate 28 is arranged in the total air supply channel 22 and is opposite to the air supply port 121b, the width and the position of the honeycomb hole-shaped structure 281 are arranged corresponding to the central air supply channel 23 and the air supply port 121b of the air conditioner 121, so that the cold air blown out by the air guide plate 121b can reach the central air supply 23 at the rear part of the air guide plate 28 for exchanging heat, and the honeycomb hole-shaped structure 281 can be blocked, and the air speed can be blocked at the same time, and the air guide hole-shaped structure 281 can be blocked at the position corresponding to the central air channel 23, and the uniform air flow channel 24 and the air flow speed can be guaranteed, and uniform, and the air flow speed can be uniform, and the air flow channel 24 can be blown to the uniform.
In some embodiments, as shown in fig. 7, the baffle 28 includes a main plate 282 and a flow control plate 283 connected to the main plate 282 for adjusting the air supply direction.
Since the air outlets 121b of the air conditioning units 121 with different specifications are located at different positions, if the air guide plate 28 is a flat plate without bending radian, when the air outlets 121b are located at the upper or lower positions, the air volumes at the upper side and the lower side of the air guide plate 28 cannot be unified.

The return air cover 27 is arranged on the energy storage cabinet body 1 and is sealed with the return air inlet 121a on the air conditioning unit 121 through the sealing piece 271, when the back door 12 of the air conditioning unit 121 is installed and is opened, the return air cover 27 is separated from the return air inlet 121a, and when the back door 12 is closed, the sealing piece 271 can fill a gap between the two parts, so that the two parts are tightly connected, the return air can be guaranteed to stably circulate, the return air is prevented from leaking and flowing in a mixed mode with cold air, and the cooling and radiating effects of the energy storage cabinet are affected.
In some embodiments, an electric cabin 3 is further disposed in the energy storage cabinet body 1 and parallel to the battery cabin 2, and a power conversion module 31, a main control box 32, a distribution box 33 and a circuit breaker 34 are installed in the electric cabin 3 along the height direction.
In some embodiments, a louver 35 for ventilation is disposed at a position of the energy storage cabinet body 1 close to the electric cabin 3, an air outlet is disposed at the rear of the electric cabin 3, and a negative pressure fan is disposed in the electric cabin 3 to cooperate with the louver 35 and the air outlet to dissipate heat in the electric cabin 3.
In this embodiment, as shown in fig. 2, the electric cabin 3 and the battery cabin 2 are arranged in parallel, so that the electric cabin is inherited integrally, the occupied area is reduced, the system integration rate is improved, and the electric cabin is convenient to transport and install. The energy storage cabinet body 1 is divided into an electric cabin 3 and a battery cabin 2 by an intermediate partition plate. The power conversion module 31, the main control box 32, the distribution box 33, and the circuit breaker 34 are mounted in the electric cabin 3 in the height direction, and the air conditioning unit 121, the baffle 28, and the battery pack 211 are mounted in the battery cabin 2. The integrated design method improves the system integration rate and reduces the occupied area.
Wherein, through the negative pressure fan (not shown in the figure) in the electric cabin 3, outside air is inhaled through the shutter 35 to cool the power conversion module 31 in the electric cabin 3, and is discharged through the air outlet (not shown in the figure) at the back of the electric cabin 3, thereby ensuring safe and efficient operation of the power conversion module 31.
The applicant declares that the above is only a specific embodiment of the present utility model, but the scope of the present utility model is not limited thereto, and it should be apparent to those skilled in the art that any changes or substitutions that are easily conceivable within the technical scope of the present utility model disclosed by the present utility model fall within the scope of the present utility model and the disclosure.
