HIGH PRESSURE CHAMBER AND METHOD OF HIGH PRESSURE CHAMBER COOLING Russian patent published in 2015 - IPC B30B11/00 B22F3/15 F27B17/00 

FIELD: technological processes.

SUBSTANCE: this invention relates to treatment of items with hot pressing, preferably by hot isostatic pressing. The pressing device comprises a furnace chamber located inside a high pressure chamber of a device and surrounded with a heat insulated jacket. Under the furnace chamber there is the lower insulating section. For circulation of the working medium under pressure in the furnace chamber there is a fan with adjustable number of rotations. In the device there is at least one supply channel with an outlet. The specified channel provides for connection between the zone under the lower insulating section and the fan inlet for mixing of the flow from the specified zone with a flow in the channel above the lower insulating section and below the furnace chamber. At the same time it is possible to adjust the specified mixed flow by correction of number of fan rotations.

EFFECT: invention provides for accurate regulation of working medium temperature under pressure and speed of its variation.
