Description

Technical Field

[0001] The invention patent relates to the field of energy storage battery racks, and specifically, to an energy storage battery heat dissipation rack. Background Art

[0002] In the prior art, the battery bodies are tightly stacked inside the box of the energy storage battery container, making it difficult to dissipate heat. Since the internal temperature of the battery is usually relatively high when it is working, it is necessary to actively cool the battery. There are two cooling methods for energy storage battery containers: air cooling and liquid cooling. Among them, the liquid cooling method has the safety hazard of leakage, while the air cooling method can avoid this. However, the air cooling method usually uses air conditioning to cool the entire box, and the cooling effect is relatively poor. In summary, whether it is the existing battery body placement method or the air cooling method, the heat exchange efficiency of the battery pack is relatively low. Summary of the invention
