A semiconductor cooling sheet 203 is fixed inside the water storage tank 201, a water pump 204 is fixed on the top of the water storage tank 201, and a control panel is provided on the front of the water storage tank 201.

The water pump 204 is connected to the control panel through the existing technology, the water inlet pipe 205 is fixed to the water inlet end, the water inlet pipe 205 extends to the inside of the water tank 201, and the inside of the insulation shell 202 is provided with a meandering cooling pipe 206, the meandering cooling pipe 206 is fixed to the water outlet end of the water pump 204, the water outlet end of the meandering cooling pipe 206 extends to the inside of the water tank 201, and the water source in the meandering cooling pipe 206 is continuously input through the water pump 204 and automatically flows back to the water tank 201.

[0028] A pick-and-place assembly 3 is provided above the cooling pool 1, and the pick-and-place assembly 3 is used to pick up and place the smelt in the cooling pool 1. The pick-and-place assembly 3 includes two winding rods 301 that are rotated on the top of the cooling pool 1 through a support column and a carrying plate 302 arranged inside the cooling pool 1. One end of the two winding rods 301 is fixed with a pulley 303, and a belt 304 is sleeved between the outer surfaces of the two pulleys 303. The belt 304 drives the two winding rods 301 to rotate and reel at the same time. A driving machine 305 is fixed at one end of one of the winding rods 301, and the driving machine 305 is electrically connected through the existing technology and the external control system. Two ropes 306 are wound around the outer surfaces of the two winding rods 301, and the ropes 306 on the two winding rods 301 are wound in the same direction to ensure that the ropes 306 are reeled in or released together when the winding rods 301 rotate in the same direction, and one end of the rope 306 passes through the cooling pool 1 and is fixed to the top of the carrying plate 302.

[0029] A waste heat protection component 4 is provided on the top of the cooling pool 1. When the smelt is put into the cooling pool 1, the hot steam generated instantly will drift to the outside from the access port. The waste heat protection component 4 is used to prevent the hot steam inside the cooling pool 1 from dissipating outward. The waste heat protection component 4 includes a protective shell 401 fixed to the top of the cooling pool 1. The protective shell 401 is outside the access hole.

A fan blade 503 is fixed at one end of the output shaft of the motor 502, and the fan blade 503 is located above the waste heat collection hole. The motor 502 drives the fan blade 503 to draw hot steam into the protective cover 501 and transport it to the designated use position.

[0031] In order for those skilled in the art to fully understand the technical solution, this application makes the following overall summary:

[0032] When in use, the driving machine 305 is used to drive the winding rod 301 to rotate. The winding rod 301 makes the two winding rods 301 rotate in the same direction at the same time through the belt 304, so as to reel in the rope 306. As the rope 306 is reeled in, the supporting plate 302 rises to the bottom of the protective shell 401, the smelt is placed on the supporting plate 302, and the protective cover 402 is covered. The driving machine 305 is reversed to release the rope 306, and the supporting plate 302 falls into the coolant with the smelt. The protective cover 402 blocks the hot steam in advance when it is generated, so as to recover the waste heat to the maximum extent and avoid the loss of waste heat.

[0033] When the hot steam is drawn into the protective cover 501 by the fan blades 503, the water pump 204 starts to pump the water in the water tank 201 into the circular cooling pipe 206. The circular cooling pipe 206 takes away the heat through the outside of the motor 502 to prevent the hot steam temperature from being too high and causing damage to the motor 502, thereby preventing the motor 502 from being in a high temperature environment for a long time and quickly losing its service life.
