Lightweight new energy battery pack liquid cooling plate assembly

The utility model provides a light-weight liquid cooling plate assembly of a new energy battery pack. The light-weight liquid cooling plate assembly comprises an aluminum plate, a plurality of liquid cooling pipes, a liquid inlet collecting pipe and a liquid outlet collecting pipe, a plurality of liquid cooling pipes are uniformly mounted on one side surface of the aluminum plate; and two ends of each liquid cooling pipe are respectively communicated with the liquid inlet collecting pipe and the liquid outlet collecting pipe. The liquid cooling pipe and the aluminum plate are combined to replace a traditional stamping plate runner structure, the development period and the die cost are reduced, the weight is reduced by more than 30%, and the cost is reduced by 20%. 本实用新型提出了一种轻量化新能源电池包液冷板总成，包括铝板、多个液冷管、进液集流管和出液集流管；多个液冷管均匀安装在铝板一侧面上，液冷管两端分别与进液集流管、出液集流管连通。本实用新型通过液冷管与铝板的结合取代传统冲压板流道结构，减少开发周期以及模具费费用，重量减轻30％以上，成本降低20％。
