Technical Field

[0001] The invention relates to the field of aluminum ingot processing equipment, in particular to aluminum ingot cooling equipment for an aluminum ingot production line. Background Art

[0005] However, this aluminum ingot cooling device of the aluminum ingot production line also has some defects.

[0015] As a further solution of the present invention: a turbulator is installed inside the turbulence tube at the position where the air inlet pipe is connected to the turbulence tube, one side of the turbulator is facing the hot air pipe, a spiral tube is installed inside the hot air pipe, and an air expansion nozzle is installed inside the hot air pipe at the outlet position of the spiral tube; the middle of the turbulator is connected to the cold air cavity.

Due to the difference in angular velocity, friction is generated between the layers of the free vortex, and the airflow in the center layer loses energy, has low kinetic energy, reduced speed, and reduced temperature, and becomes a cold airflow that is discharged through the cold air cavity. The airflow in the outer layer gains momentum, resulting in an increase in kinetic energy, and at the same time, it continuously rubs against the turbine tube wall, converting part of the kinetic energy into heat energy, forming a hot airflow that is finally discharged from the expansion nozzle, achieving rapid cooling of the original hot air while also heating the air after heat exchange to a higher temperature, so as to regain heat at a higher temperature for use.
