| description | A hot isostatic pressing device (1) according to the present invention includes an inner casing (3), an outer casing (4), and a heating means (7) which are provided inside a high-pressure container. The device further includes a first cooling means (41) for forcedly circulating pressure medium gas in such a manner that pressure medium gas guided upwardly between the inner casing (3) and the outer casing (4) is guided to the outside of the outer casing (4) through an upper part of the outer casing (4), cooled while being guided downwardly along an inner circumferential surface of the high-pressure container, 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 (43) for guiding pressure medium gas within a 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 forcedly circulated by the first cooling means, and returning the cooled pressure medium gas into the hot zone. According to such a structure, a high cooling efficiency can be attained while maintaining the hot zone in a thermally uniform condition. |
