Furthermore, the water-cooling plate 11 of the present invention can improve the bearing strength of the water-cooling plate 11 and reduce the cost increase of the water-cooling plate 11 by arranging the edge strips 112 and 113 with strength greater than that of the water-cooling plate main body 111 at the two opposite sides of the water-cooling plate main body 111, and when the water-cooling plate 11 is supported below the module 21 in the battery pack, the edge strips 112 and 113 with high strength can provide strong support for the module 21, so as to effectively improve the bearing effect of the water-cooling plate 11, ensure the bearing reliability of the water-cooling plate 11, and further improve the safety and reliability of the battery pack.
Currently, most of the battery packs have a square module, and based on the shape of the module, according to an embodiment of the present invention, the water-cooling plate 11 is correspondingly square, specifically, for example, as shown in fig. 1, the water-cooling plate 11 is substantially rectangular, the first side 1111 and the second side 1112 are parallel to each other and are two long sides of the water-cooling plate main body 111, and the first side 112 and the second side 113 extend over the entire length of the first side 1111 and the second side 1112, respectively, that is, the length of the first side 112 is substantially equal to the length of the first side 1111, and the length of the second side 113 is substantially equal to the length of the second side 1112.
