Abstract
The invention relates to a method for regulating the temperature of a hot isostatic press and to a hot isostatic press, consisting of a pressure vessel (1) having an interior loading space (19) and insulation (8) arranged in between, wherein heating elements (4) and a loading space (19) having a load (18) are arranged inside the insulation (8), wherein at least the loading space (19) is surrounded by a convection sleeve (27) to form a convection gap (28). Fluid is sprayed through at least one nozzle (13) in the interior of the pressure vessel (1) and/or the loading space (19) to generate a rotational flow (23) so that said fluid mixes with the fluid held therein, and said fluid simultaneously forms a circulation (29) around the convection sleeve (27) and enters the loading space (19) via the convection gap (28). The invention also relates to a hot isostatic press in which at least one conduit (12) that is connected to at least one nozzle (13) within the pressure vessel (1) is arranged inside the pressure vessel (1), wherein the discharge angle of the nozzle (13) is suited to form a rotational flow (23) within the loading space (19), and wherein the conduit (12) is connected to an area of the pressure vessel (1) having a different temperature.
