Heat treatment system and a method for cooling a loading chamber

摘要

A heat treatment system and method for cooling a loading chamber that includes a heat treatment furnace for heat-treating an object to be treated. The heat treatment furnace includes a throat for carrying the object in and out, and a cooling mechanism for cooling the vicinity of the throat. The cooling mechanism has a ventilating unit with a ventilating port for sending a cooling fluid toward the vicinity of the throat and a heat exchanger arranged so as to face the ventilating port in the vicinity of the throat. The cooling mechanism also has an intake fan for sucking the cooling fluid in the vicinity of the throat over the heat exchanger. When the object to be treated is carried in, the structure of various mechanisms in the vicinity of the throat is simplified, and space is saved.
