With the rapid development of renewable energy, energy storage cabinets have become important equipment for storing electrical energy. During the energy storage process, a large amount of heat will be generated, which needs to be effectively dissipated to maintain the normal operating temperature of the energy storage cabinet.

[0003] In the prior art, the temperature control of the battery compartment is usually achieved by directly delivering airflow to the energy storage cabinet using an air conditioner. However, the airflow directly delivered by the air conditioner is easily dispersed disorderly due to the obstruction of the top of the battery compartment, resulting in a low air flow at the bottom of the energy storage cabinet, which in turn causes a large temperature difference between the upper and lower parts of the energy storage cabinet, affecting the temperature regulation effect of the energy storage cabinet.

[0004] Therefore, in view of this, the shortcomings of the existing structure are studied and improved, and an air duct structure of an energy storage device is proposed. Utility Model Content

[0007] Furthermore, overhead legs are fixed at four corners of the bottom of the battery rack group, and a hollow overhead layer is formed between the four overhead legs.

[0008] Furthermore, slots are symmetrically provided on both sides of the battery rack assembly, and the dimensions of the slots match the shape of the mounting plate.

[0012] Furthermore, an air outlet duct is fixed on the right side of the top of the energy storage cabinet, and a reflux channel located on the right side of the battery rack group is correspondingly arranged on the inner side of the air outlet duct.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1.
