Description

Technical Field

[0001] This utility model relates to the field of liquid-cooled battery housing technology, specifically to a liquid-cooled battery housing for energy storage. Background Technology

[0002] Liquid-cooled battery enclosures for energy storage refer to enclosure structures used in energy storage systems that cool battery packs through liquid circulation. Their main functions are to support and protect the battery packs and effectively dissipate heat through the liquid cooling system, ensuring the battery packs maintain a suitable operating temperature during charging and discharging, thereby improving system stability and lifespan. However, existing liquid-cooled battery enclosures for energy storage, while using liquid cooling plates to dissipate heat from the battery packs, still have room for improvement in heat dissipation performance. Furthermore, the bottom of the enclosure is constructed from multiple welded plates, resulting in relatively poor overall strength. Therefore, this paper proposes a liquid-cooled battery enclosure for energy storage with higher overall strength and better heat dissipation performance. Utility Model Content
