Battery pack and heat exchange plate

Abstract

The utility model discloses a kind of heat exchange plates, including heat exchange plate main body, the heat exchange plate main body is at least partially arranged between the first side of two adjacent battery monomers, the first side is the large face of the battery monomer;The part of the heat exchange plate between the first side is provided with cavity structure, multiple support portions are spaced apart along the height direction of the heat exchange plate, and accommodating cavity is formed between adjacent two support portions, the wall thickness of the accommodating cavity one side is L1, the width of the accommodating cavity is L2, the range of L1 / L2 is 0.1-1.The heat exchange plate of the utility model can not only meet the strength needs of heat exchange plate, but also improve the deformation capacity of heat exchange plate, so that the deformation capacity of heat exchange plate is better, and the damage probability when battery monomer expands is reduced.The utility model further discloses a kind of battery pack.
