[0023] Specifically, the air-conditioning room 7 is equipped with an air conditioner; the electrical room 3 is equipped with electrical equipment. In actual use, the cold air blown out by the air conditioner enters the cabinet 1 through the air outlet of the air-conditioning room 7, and enters the rear side of the cabinet 1 through the air inlet channel 4. The cold air flowing out to the rear side of the cabinet 1 is shielded by the wind shield 5, so that the cold air flows downward to the multiple battery plug boxes 2, and enters the battery plug box 2 through the box air inlet 11, cools down the electrical components in the battery plug box 2, and then flows out from the box air outlet 8 to the front side of the cabinet 1 under the action of the fan 9 of the box air outlet 8, and enters the air-conditioning room 7 through the air inlet of the air-conditioning room 7, thereby completing the gas circulation of the energy storage cabinet, taking away the heat in the energy storage cabinet, and completing the cooling. The utility model sets the electrical room 3 on one side of the battery plug box 2, reduces the overall height of the energy storage cabinet, facilitates the packaging and transportation of the energy storage cabinet, and makes the structure of the energy storage cabinet more compact. Furthermore, the wind shield plate 5 is arranged at the outlet of the air inlet channel 4, so that the cold air is directed to the battery plug box 2 below, thereby improving the utilization efficiency of the cold air. Furthermore, a plurality of wind shield strips 10 are arranged behind the battery plug box 2. When it is necessary to increase the length of the box air inlet 11 of the battery plug box 2, one or more wind shield strips 10 can be removed from the battery plug box 2 by tools according to actual needs, thereby increasing the length or size of the box air inlet 11, thereby facilitating the rapid entry of cold air into the battery plug box 2, meeting different installation requirements, and increasing the practicality and utilization rate of the utility model.

[0024] Furthermore, the energy storage cabinet further includes a reinforcing rib 15 disposed at the bottom end of the cabinet body 1. The reinforcing rib 15 is added to improve the load-bearing capacity of the utility model.

[0025] Furthermore, the air inlet of the air-conditioning chamber 7 is located below the air outlet of the air-conditioning chamber 7 .

[0026] In actual use, the air inlet of the air-conditioning room 7 is arranged below the air outlet of the air-conditioning room 7, which is conducive to the cold air circulating from top to bottom before entering the air-conditioning room 7. The circulating flow of gas has high heat dissipation efficiency.

[0027] Furthermore, the energy storage cabinet also includes a first air collecting member 12 disposed on the front cabinet door 6 , and the first air collecting member 12 is used to connect the air outlet and the air inlet channel 4 of the air-conditioning room 7 .

[0028] In actual use, the first air collecting member 12 is added to guide the cold air blown out of the air-conditioning room 7 into the air inlet channel 4 to prevent the cold air from being retained at the front side of the cabinet 1 , thereby improving the cooling efficiency of the battery box 2 .

[0029] Furthermore, the energy storage cabinet also includes a second air collecting member 13 disposed on the front cabinet door 6 , and the second air collecting member 13 blocks the air inlet of the air-conditioning room 7 and extends downward.

[0030] During actual use, the air inlet of the air-conditioning room 7 and the front space of the cabinet 1 are connected through the second air-collecting piece 13, and the air exhausted from the air outlet of the battery box 2 enters the front side of the cabinet 1. The second air-collecting piece 13 is added to guide the gas on the front side of the cabinet 1 downward along the outer wall of the second air-collecting piece 13, and then enter the second air-collecting piece 13 from below, and finally guide it to the air inlet of the air-conditioning room 7 through the second air-collecting piece 13, thereby further optimizing the gas flow path of the energy storage cabinet.

[0031] Furthermore, the cross-sectional view of the second air collecting member 13 is in the shape of a letter 7. The second air collecting member 13 has a simple structure and the front cabinet door 6 is easy to install.

[0032] Furthermore, the energy storage cabinet also includes a rear cabinet door 14 rotatably disposed on the rear side of the cabinet body 1 .

[0033] In actual use, the rear cabinet door 14 is added. When the windshield strip 10 on the rear side of the battery plug box 2 needs to be removed, the rear cabinet door 14 can be directly opened to operate, thereby reducing the installation and removal steps of the battery plug box 2.

[0034] All technical features in this embodiment can be freely combined according to actual needs.

[0035] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
