According to the present situations of the two production lines and the temperature needed by the producing technics of the heat-exchanger , using the numerical simulation with the Airpark software to analyze the reason why the cooling system can not meet the technicals requirement; with the heat transfer theory computation based on the heat transfer principle, the technical parameters of the cooling sect refer to the system technic and configuration are obtained. That are made for reasonable organization of the airflow of the cooling system and the new cooling equipment achieving the technical requirement. At the same time, it will ease the thermal pollution of the circumjacent environment and improve IAQ of the workshop
