Patent ID: 8695494

Claim:
A method for rapid cooling a hot isostatic press comprising a pressure container having an internal load space and comprising insulation disposed at least partially around the load space, heating elements disposed inside the insulation, and a load disposed on a load bearing plate, the method comprising: directing fluid into the load space of a pressure container using at least one nozzle located in an upper region of the load space and near an inner sidewall of the insulation, the fluid from the at least one nozzle forms a rotational flow around a central axis of the pressure container, wherein the rotational flow is in contact with the load and forms along a perimeter of the insulation; and mixing the fluid from the at least one nozzle as it passes through the rotational flow around the central axis near the insulation with fluid near the load, wherein the fluid from the at least one nozzle has a lower temperature than the fluid in the load space and/or the load, wherein the fluid from the at least one nozzle is directed into the load space tangentially to the central axis of the pressure container.
