Liquid cooling plate and battery pack

The utility model belongs to the technical field of heat dissipation, and particularly relates to a liquid cooling plate and a battery pack, the liquid cooling plate comprises a cooling plate body and a protective plate, the cooling plate body is provided with a flow channel, the protective plate is arranged at the bottom of the cooling plate body, and one surface of the protective plate facing the bottom of the cooling plate body is provided with a raised line for supporting a flow channel area on the cooling plate body. The length direction of the protruding strips intersects with the direction of the flow channel located above the protruding strips, and the protruding strips can stretch across the flow channel at the bottom of the cold plate body in the width direction of the flow channel and support different areas of the flow channel in the width direction of the flow channel at the same time. Deformation of the cold plate body can be reduced, the structural strength of the cold plate body can be improve
