Abstract: According to the structure of the vacuum furnace forced cooling system widely used in China at present, and the investigation and theoretical analysis of the advanced forced cooling system in the domestic and foreign markets, it is concluded that the airflow reversed forced cooling system can improve the cooling rate of vacuum furnace and improve production efficiency with reducing energy consumption. It also improves the temperature uniformity of the workpiece, so that the workpiece being treated cools more evenly, and improves the heat treatment quality of the workpiece treated[1]. Finally, some suggestions are put forward on the structural design and development of air flow change technology for vacuum furnace forced cooling system.

Key words: vacuum furnace, forced cooling system, convection heat transfer, air flow reversing
