The heat in the water will be transferred to the multiple heat-conducting plates 7. The staff starts the fan 9, and the fan 9 rotates to generate airflow. The airflow blows through the multiple heat-conducting plates 7 to take away the heat on the heat-conducting plates 7, thereby reducing the water temperature inside the cooling box 2.
