Description

Technical Field

[0001] This utility model relates to the field of energy storage battery box technology, and in particular to a stamped liquid-cooled lower box body. Background Technology

[0002] Traditional power generation methods or new energy power generation methods all rely on energy storage systems, such as thermal power generation, hydropower generation, wind power generation, and solar energy invention. The battery packs of energy storage systems generate a lot of heat during the charging and discharging process. Therefore, how to dissipate heat and cool down the energy storage battery packs is a key technical point.

[0003] Traditional battery pack cooling typically employs air cooling, which relies on fans. However, this method is inefficient, noisy, and has a short lifespan. In contrast, liquid cooling is more efficient, provides more uniform temperature control, and results in lower temperature rise, thus extending battery life. Current liquid-cooled battery lower casings are manufactured using traditional casting or extrusion welding processes. While increasing plate thickness or using a frame structure can improve load-bearing capacity, increasing plate thickness has limited effect. Frame structures, which rely on connection points for fixation, are prone to cracking, damaging the liquid cooling plate and reducing its lifespan. This approach fails to meet the increasingly demanding requirements for lower casings.

[0004] Therefore, existing technologies need to be improved and enhanced. Utility Model Content
