The invention provides an ice storage tank with a cooling device for an evaporative supercooled water continuous ice making system, which can effectively eliminate the supercooled state of the supercooled water and realize the separation of ice water. In the ice storage tank box, the supercooled water droplets collide with the wire mesh for decooling. Its characteristic is that the two adjacent slopes of the corrugated wire mesh make some of the water droplets falling on it rebound and collide with each other, and some small ice crystals will accumulate at the angle between the slopes during the cooling process, and its effect is similar to adding water to supercooled water. In addition, the end of the uppermost wire mesh is installed on the spring, which will accelerate the nucleation and freezing of supercooled water under the action of impact, vibration and "nucleating agent".
