Description

TECHNICAL FIELD

[0003] A cooling tower for a metal silicon manufacturing system is disclosed in Chinese Patent No. CN218781654U. The working principle of the device is that when the sprayed cooling water cools the silicon ingot, a large amount of water vapor is generated. By starting the negative pressure fan, the water vapor in the tower body continuously rises, and part of the water vapor is discharged from the air pipe. During the rising of part of the water vapor, it will come into contact with the condensing plate and the fins. By connecting the circuit of the semiconductor refrigeration block, the semiconductor refrigeration block generates low temperature. The low temperature is conducted to the condensing plate and the fins. After the water vapor meets the condensing plate and the fins, it quickly condenses into water droplets. The water droplets accumulate and then fall into the tower body again. Part of the water sprayed by the spray head and the condensed water droplets enter the water tank from the filter screen, realizing the reuse of water resources and avoiding waste.
