COMBINED FAN AND EJECTOR COOLING

Quintus Technologies AB, ...

1. A pressing arrangement for treatment of at least one article by hot isostatic pressing, the pressing arrangement comprising a pressure vessel including:a furnace chamber comprising a furnace, wherein the furnace chamber is at least in part surrounded by a heat insulated casing, and wherein the furnace chamber includes a load compartment configured to hold at least one article to be treated, wherein the load compartment is arranged so as to allow for a flow of pressure medium through the load compartment; and
at least two flow generators arranged for generating the flow of pressure medium into the load compartment, wherein the flow of pressure medium into the load compartment is generated by transporting pressure medium upwards from a space below a bottom insulating portion and above a bottom end portion of the pressure vessel and injecting the pressure medium into the load compartment by way of a transport pipe having an inlet arranged within the space, a section coupled to the inlet and extending through the bottom insulating portion, and an outlet coupled to the section;
wherein the at least two flow generators comprise
a primary flow generator arranged below the bottom insulating portion, and
a secondary flow generator arranged in relation to the primary flow generator so as to receive the flow of pressure medium generated by the primary flow generator and generate the flow of pressure medium into the load compartment,
with the primary flow generator comprising a primary lower bell-mouth end of an intermediate pipe and a nozzle for delivering the pressure medium to the primary lower bell-mouth end of the intermediate pipe, and with the secondary flow generator comprising a secondary lower bell-mouth end aligned with the inlet of the transport pipe and receiving the pressure medium delivered by the intermediate pipe of the primary flow generator.
