The cooling duct 31 has an opening 311 toward the battery holder 1.

In the vertical direction, the height of the heat dissipation assembly 32 is higher than the height of the battery frame 1. The heat dissipation assembly 32 blows cold air into the cooling air duct 31, and the cold air takes away the heat in the battery 2 through the opening 311.

The heat dissipation assembly 32 includes a limiting block 321 disposed at two sides, a supporting frame 322 disposed between the two limiting blocks 321, and a fan 323 fixed on the supporting frame 322.

The limiting block 321 protrudes towards the fan 323 and is provided with a limiting piece 3211, the bottom of the limiting block 321 protrudes towards the supporting frame 322 and is provided with a supporting bar 3212, and the limiting piece 3211 is a limiting shaft or a limiting bearing. In this embodiment, the limiting member 3211 is a limiting shaft. Screw holes are formed at the end parts of the two limiting blocks 321.

The limiting block 321 is integrally formed with the cooling air duct 31.

The support bar 3212 serves to support the support frame 322 and the fan 323 in a vertical direction.

As shown in fig. 5, the supporting frame 322 is disposed on the supporting bar 3212, the supporting frame 322 includes a fixing bar 3221 disposed at the bottom of the fan 323, a fixing plate 3222 disposed at one end of the fan 323, a fixing screw 3223 for fixedly connecting the fixing plate 3222 with the limiting block 321, a limiting bar 3224 extending from the fixing bar 3221 toward a side far away from the supporting bar 3212, a guiding portion 3225 disposed at one end of the limiting bar 3224 toward the limiting member 3211, and a handle 3226 disposed at one side of the fixing plate 3222 far away from the fan 323.

The fan 323 blows air towards the cooling air duct 31, and the fixing strips 3221 are used for supporting the fan 323, and in addition, the fixing strips 3221 on two sides of the fan 323 are arranged at intervals so that the fan 323 is fully exposed, so that cold air can be blown out.

The width of the fixing plate 3222 is greater than the distance between the two limiting blocks 321, the fixing screws 3223 are arranged at two ends of the fixing plate 3222, and the fixing screws 3223 are in threaded fit with screw holes, so that the fixing plate 3222 and the limiting blocks 321 are fixed, and the effect of fixing the heat dissipation assembly 32 is achieved.

When the heat dissipation assembly 32 is fixed, the guiding portion 3225 is located below the limiting member 3211. The guiding portion 3225 is configured to enable the supporting frame 322 to better match with the limiting block 321.

The air inlet duct 33 is used for supplying air to the fan 323 and the cooling air duct 31.

The energy storage battery cluster level device 100 of the present utility model is used as follows: the cooling air duct 31 is fixed to the battery rack 1, the fan 323 is fixed to the supporting frame 322, the supporting frame 322 with the fan 323 is inserted between the two limiting blocks 321 along the horizontal direction until the limiting strips 3224 are abutted to the limiting pieces 3211, and then the fixing screws 3223 are screwed down, so that the installation can be completed. When the fan 323 is required to be maintained in the later period, the fixing screw 3223 is only required to be unscrewed, so that the fan is simple and convenient.
