The invention relates to the technical field of liquid-cooled battery packs, provides a top-bottom liquid-cooled battery pack, and aims to solve the problem that the screwing degree of bolts at all positions cannot be automatically increased when a vehicle bumps in the conventional battery pack. The device comprises a shell, a top plate is mounted above the shell, a screwing assembly is mounted in the top plate, through holes are formed in the left side and the right side of the shell, and the through holes are formed in the left side and the right side of the shell. And a rotating rod is rotationally installed in the through opening, fans are fixedly installed on the upper side and the lower side of the rotating rod, motors are fixedly installed on the left side and the right side of the upper surface of the top plate, and output shafts of the motors are connected with the rotating rod. According to the battery pack, the top liquid cooling plate can be automatically melted through during thermal runaway, coo
