description The utility model relates to a cooling device and a battery pack, the cooling device comprises a shell and a valve core, one end of the top of the shell is provided with a water inlet, and the middle part of the bottom of the shell is provided with a water outlet; the valve element is arranged in the shell and can move in the body length direction of the shell so that the water inlet and the water outlet can be communicated or disconnected. And the water outlet is directly communicated with the shell of the battery pack. When the battery pack is subjected to thermal runaway, water is injected into the water inlet, water flows through the shell and enters the battery pack through the water outlet, the battery cell module in the battery pack is cooled, meanwhile, water flows out of the pressure release valve of the battery pack, the safety performance is good, and the structure is simple. And the valve core is also arranged at the water outlet, so that the water inlet and the water outlet can be communicated or
