Liquid cooling plate and battery pack

The utility model discloses a liquid cooling plate and a battery pack, and belongs to the technical field of power batteries. The liquid cooling plate comprises the cooling plate body and the heating piece, the heating piece is arranged on the edge of the cooling plate body, the heating piece is arranged on the cooling plate body in advance, the heating piece is assembled along with the cooling plate body, the liquid cooling plate is not limited by an external structure and is more flexible, the structure is simple, and structural layout is convenient. The heating piece is arranged on the edge of the cold plate body, the problem that temperature distribution is not uniform can be effectively solved for products with the peripheral temperature lower than the middle temperature, and therefore the performance of the products is improved. When the liquid cooling plate is used for the battery pack, the condition of non-uniform temperature distribution of the battery pack is effectively improved, and the heat prese
