Water cooling plate structure of automobile power battery

The utility model discloses a water cooling plate structure of an automobile power battery, which comprises a closed water cooling plate, an inner cavity is arranged in the water cooling plate, and a plurality of ribs arranged in sequence are arranged on the inner wall of the inner cavity. According to the water-cooling plate structure of the automobile power battery, the contact area of cooling liquid and the water-cooling plate is increased, so that the water-cooling plate can take away more heat on a heat conduction material, and a battery cell can be cooled more quickly. 本实用新型公开了一种汽车动力电池水冷板结构，包括封闭形状的水冷板，水冷板内设有内腔，内腔的内壁上设有若干个依次排列的筋条。本实用新型提供了一种汽车动力电池水冷板结构，增加冷却液与水冷板的接触面积，使水冷板能带走导热材料上更多热量，使电芯能更快的降温。
