Abstract
An apparatus includes a cooling plate with a central opening. The central opening within the cooling plate is positioned to be opposite an opening in a workpiece when the cooling plate is positioned at a target location opposite the workpiece. The cooling plate is configured to absorb heat from a gas heated by the workpiece. A diffuser is in the central opening of the cooling plate. The diffuser is configured to receive a gas from a gas input. The diffuser is further configured to slow a flow of the gas and output the gas into the workpiece opening.
Claims20
An system comprising:
- a cooling chamber;
- a carrier configured to position a workpiece at a target location within the cooling chamber, wherein the workpiece includes an inner diameter, and outer diameter, and a workpiece opening at the inner diameter;
- a first cooling plate including a first cooling plate central opening, wherein the first cooling plate central opening is positioned opposite the workpiece opening when the workpiece is positioned at the target location;
- a first diffuser in the first cooling plate central opening, wherein the first diffuser is configured to reduce a first velocity of a first gas from a first gas input to the workpiece opening;
- a second cooling plate including a second cooling plate central opening, wherein the second cooling plate central opening is positioned opposite the workpiece opening and the first cooling plate central opening when the workpiece is positioned at the target location;
- and
- a second diffuser in the second cooling plate central opening, wherein the second diffuser is configured to reduce a second velocity of a second gas from a second gas input to the workpiece opening.

An apparatus comprising:
- a first diffuser within a first cooling plate;
- a second diffuser within a second cooling plate, wherein the second diffuser is positioned opposite the first diffuser;
- a first gas input in the first cooling plate, wherein the first gas input injects a first gas through the first diffuser and into an open space between the first diffuser and the second diffuser;
- and
- a second gas input in the second cooling plate, wherein
- the second gas input injects a second gas through the second diffuser and into the open space between the first diffuser and the second diffuser, and
- the first cooling plate and the second cooling plate are positioned to permit a flow of a mixture of the first gas and the second gas from an inner diameter of the first and second cooling plates to an outer diameter of the first and second cooling plates.
