気相式加熱方法及び気相式加熱装置
Document Type and Number:
Japanese Patent JP6799814
Kind Code:
B2
Abstract:
In a vapor-phase type heating method, an object is heated by a heated gas containing vapor in a heating furnace. The heat transfer fluid falling from a front surface of the object to a lower portion of the heating furnace is collected, after the vapor comes into contact with the object and cools to liquefy and latent heat of vaporization of the vapor is applied to the object through phase change. The heated gas obtained after heating the object is discharged from an inside of the heating furnace to the circulation route. In the circulation route, the heat transfer fluid is supplied as droplets to the discharged heated gas and is vaporized after heating, and the heated gas including the vapor is supplied to the heating furnace.
