<p><P>PROBLEM TO BE SOLVED: To attain a high cooling efficiency while maintaining a hot zone in a thermally uniform condition in a hot isostatic pressing device. <P>SOLUTION: This hot isostatic pressing device 1 includes an inner casing 3, an outer casing 4, and a heating means 7 which are provided inside a high-pressure container 2. The device further includes a first cooling means for forcibly circulating a pressure medium gas in such a manner that the pressure medium gas guided upward between the inner and outer casings 3, 4, is guided to the outside of the outer casing 4 through an upper part of the outer casing 4, cooled while being guided downward along an inner circumferential surface of the high-pressure container 2, and then returned to between the inner casing 3 and the outer casing 4 through a lower part of the outer casing 4, and a second cooling means for guiding the pressure medium gas within the hot zone formed inside the inner casing 3 to the outside of the hot zone, cooling the pressure medium gas guided to the outside by merging it with the pressure medium gas forcibly circulated by the first cooling means, and returning the cooled pressure medium gas into the hot zone. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
