One end of the water supply pipe 3 is connected to the cold water chamber 102, and a first water pump is arranged at the connection between the water supply pipe 3 and the cold water chamber 102. The upper spray pipe group 4 is installed on the jet flow cover 106 and is used for spraying the part of the aluminum alloy ingot except the bottom. The upper spray pipe group 4 and the lower spray pipe group 5 are prior arts, and their specific structures and principles are detailedly recorded in the patent with the authorization announcement number CN220612277U, so they will not be elaborated here. The lower spray pipe group 5 is installed inside the hot water chamber 101 and above the filter screen 105, and is used for spraying the part of the aluminum alloy ingot except the top. One end of the water supply pipe 3 far away from the cold water chamber 102 is connected to the upper spray pipe group 4 and the lower spray pipe group 5.

[0021] Furthermore, the input end of the chiller 6 is connected to the hot water chamber 101 through a water extraction pipe 601, and the output end of the chiller 6 is connected to the cold water chamber 102 through a drain pipe 602.
