COOLING PLATE ASSEMBLY

A cooling plate assembly, comprising a first cooling plate, a second cooling plate, and a connecting member. The first cooling plate and the second cooling plate each comprise a mounting potion; and the connecting member is sealedly connected to mounting potions. The cooling plate assembly comprises a positioning potion. In an assembly direction of the mounting potions and the connecting member, the positioning potion limits the relative movement of the connecting member and the mounting potions. In the assembly direction of the mounting potions and the connecting member, the cooling plate assembly limits the relative movement of the connecting member and the mounting portions by means of the positioning portion. That is, during assembly, the positioning portion achieves a blocking effect on the connecting member or the mounting portions, so as to position the assembly, thereby reducing the mounting difficulty.
