When you want to lower the temperature inside the cooling bin 1, the temperature inside the cooling bin 1 is conducted to the outside of the cooling bin 1 through the heat sink 19. At this time, turn on the heat sink fan 18, which drives the air to flow and take away the heat on the heat sink 19, while lowering the temperature of the heat sink 19. At the same time, the heat sink 19 will cause the cooling liquid evaporated by the steel to condense on the surface of the heat sink 19, and then fall down the slope to continue cooling the steel, thereby lowering the temperature inside the cooling bin 1 while reducing the amount of cooling liquid used.
