[0039] The energy storage cabinet provided in this embodiment is used for storing energy and has a good heat dissipation effect.

[0040] like Figures 1 to 3 As shown, a specific implementation of the energy storage cabinet provided in this embodiment includes a cabinet body 1, a battery cluster 5, a heat exchange device and a fan 8.

[0041] The heat of the battery cluster 5 in the placement area 2 is absorbed by the heat exchange pipe 7, and the battery cluster 5 is cooled. At the same time, under the action of the fan 8, the heat dissipation effect in the cabinet 1 is improved to prevent the local temperature of the battery cluster 5 from being too high and affecting its life and performance. Specifically, the cabinet 1 is a rectangular structure, and there is no baffle between the placement area 2 and the ventilation area 3, which are in a connected state. A battery rack is provided in the placement area 2 for installing the battery cluster 5. The fan 8 works to timely replace the airflow in the cabinet 1 with the external airflow to complete the heat dissipation of the cabinet 1.

[0042] like Figure 2 and Figure 3 As shown, in the energy storage energy cabinet provided in this embodiment, the placement area 2 and the ventilation area 3 are adjacently arranged along the length direction of the cabinet body 1. The two areas are arranged adjacently in the transverse direction, so that the structure of the cabinet body 1 is compact, and heat dissipation and ventilation of the cabinet body 1 are achieved in the case of a small volume of the energy cabinet. Specifically, the ventilation area 3 can be arranged on the left or right side of the placement area 2. In addition, as an alternative implementation, the ventilation area 3 can also be arranged above the placement area 2.

[0043] like Figure 2 As shown, in the energy storage energy cabinet provided in this embodiment, the ventilation area 3 includes a first installation area 9, the heat exchanger 6 is arranged in the first installation area 9, a second installation area 10 is arranged above and / or below the first installation area 9, and the fan 8 is arranged in the second installation area 10.

[0048] like Figure 1 As shown, in the energy storage cabinet provided in this embodiment, the ventilation opening 4 is a grid structure, which achieves a ventilation effect and also avoids a large area of ​​the interior being exposed to the outside, so that dust and impurities fall into the cabinet body 1.

[0049] In the energy storage cabinet provided in this embodiment, the heat exchanger 6 is a liquid-cooled heat exchanger 6. In addition, as an alternative implementation, the heat exchanger 6 may also be an air-cooled heat exchanger.

With the cooperation of the heat exchanger 6 and the fan 8, the heat dissipation effect is greatly improved, avoiding excessive local temperature in the cabinet 1; and the placement area 2 and the ventilation area 3 are adjacently arranged along the length direction of the cabinet 1, so that the cabinet 1 is small and compact, avoiding excessive increase in the volume of the cabinet 1 for heat dissipation, thereby increasing costs.

[0052] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the scope of protection of the present utility model.
