Description

Heat exchange assembly and battery pack Technical Field The utility model belongs to the technical field of battery production and manufacturing, and particularly relates to a heat exchange assembly and a battery pack. Background The battery is limited by the size of the internal space of the battery, and the tight arrangement of the battery internal cells inevitably leads to heat accumulation, so that the battery needs to be radiated through a heat exchange assembly, wherein the heat exchange assembly mainly comprises a liquid collecting pipe and a heat exchange plate, the liquid collecting pipe mainly comprises a liquid inlet cavity and a liquid outlet cavity, the liquid inlet end of the heat exchange plate is connected with the liquid outlet cavity of the liquid collecting pipe, and the liquid outlet end of the heat exchange plate is connected with the liquid inlet cavity of the liquid collecting pipe.
