The liquid level sensor 17 senses the water level data, and the overflow valve 19 controls the water level. The water tank heating tube 18 controls the temperature of the water. After starting to cool, the hydraulic cylinder 11 will lower the lifting plate 12 along the slide bar 9, thereby lowering the bottom plate 13. The float ball 28 under the bottom plate 13 will be lifted by buoyancy, thereby lifting the connecting rod 26 and opening the heat insulation sealing valve body 25, so that the water flows onto the bottom plate 13 and submerges the parts to complete the cooling.
